STATEMENT OF CHIEF JUDGE BAZELON AS TO WHY HE WOULD GRANT REHEARING EN BANC..
BAZELON, Chief Judge:In large part this case involves questions arising out of the interplay between the District of Columbia (local) Criminal Code, on the one hand, and the
1. This case does not involve the problem of United States v. Thompson, 147 U.S.App. D.C. 1, 452 F.2d 1333 (1971), and I at least would have grave difficulty with an assertion that the legislature could require, in a prosecution under the national criminal code, that one Federal district court must deny important protections granted to defendants by other Federal district courts. United States (federal) Criminal Code, on the other. It also involves a due process challenge to a recent amendment to the D.C.Code requiring a defendant to prove his insanity defense by a preponderance of the evidence.1
For disarming several federal marshals, and then shooting one of them as he assisted his brother to escape, La Vance Greene was convicted of two U.S. Code offenses — -premeditated murder of a federal officer,2 and assisting a federal prisoner to escape; 3 he was also convicted of five D.C.Code offenses — felony murder,4 and four counts of armed robbery.5 The jury rejected a plea of insanity after being instructed in accordance with the recently enacted D.C. Code provision requiring a defendant to establish his plea by a “preponderance of the evidence.”
The court affirms all of appellant’s D.C.Code convictions, and vacates all of his U.S.Code convictions. A brief summary of the court’s holdings, and my views thereon, which I will address more fully below, are as follows:
I. The court holds that the D.C.Code felony murder statute applies to U.S. Code felonies. (Court’s opinion at 1150, 1151.)
In my view:
A. The court’s reasons do not support its interpretation of the D.C. Code felony murder statute, and there are strong reasons for limiting the statute to local offenses. (Pp. 1161-1164.)
*1161B. If the D.C.Code felony murder provision applies to federal offenses, it is a denial of equal protection. (Pp. 1164-1165.)
C. This court’s decision in United States v. Canty6 requires vacation
of appellant’s D.C. felony murder conviction irrespective of the general application of the D.C. felony murder provision. (Pp. 1166-1165.)
II. The court expressly recognizes that the federal premeditated murder conviction, for which sentence was imposed concurrently with the sentence on the D.C.Code felony murder conviction, raises a serious constitutional question. To avoid this serious issue, it vacates the federal homicide conviction under the Hooper doctrine.7 (Court’s opinion at 1157-1158.)
It also vacates the federal conviction for assisting escape because, as the underlying felony of the felony murder conviction, it merges into the felony murder. (Court’s opinion at 1158.)
In my view:
A. The court’s use of Hooper is an improper exercise of appellate discretion. (Pp. 1166-1167.)
B. It is manifestly improper to merge an underlying felony with a felony murder conviction. (Pp. 1168-1169.)
III. The court concludes that it need not decide whether the D.C.Code provision governing the burden of proof on an insanity plea can apply to federal offenses since it has vacated both of appellant’s U.S.Code convictions. (Court’s opinion at 1153.)
In my view:
A. The court has not vacated all of appellant’s federal offenses, because it has affirmed his D.C.Code felony murder conviction for a homicide that occurred in the commission of a federal offense. (P. 1170.)
B. The court was required to consider the application of the D.C. burden of proof statute to federal offenses even if there were no U.S. Code offenses in the present case since the statute applies in “any criminal proceeding in the United States District Court for the District of Columbia,” which must include the trial of federal offenses. (Pp. 1170-1174.)
IV. The court finds that the D.C. Code burden of proof statute governing insanity pleas may constitutionally be applied to local offenses. (Court’s opinion at 1152-1156.)
In my view:
A. Even if it applied only to local offenses, the D.C. burden of proof statute would be a denial of equal protection. (Pp. 1173-1174.)
B. The D.C. burden of proof statute is a denial of due process. (Pp. 1174-1180.)
I
Appellant was convicted of felony murder under the D.C.Code for killing a deputy marshal while assisting a federal prisoner to escape in violation of the U. S.Code. The D.C.Code felony murder provision applies to homicides committed in the course of “any offense punishable by imprisonment .in the penitentiary.” The court finds that the words “any offense” were intended to include federal offenses, and that the statute so construed is not a denial of equal protection. It also fails to consider United States v. Canty,8 which requires vacation of appellant’s local felony murder conviction irrespective of the applicability or constitutionality of the D.C.Code felony murder statute.
A. STATUTORY ANALYSIS
Until passage of the District of Columbia Court Reorganization Act of *11621970,9 all felonies committed in D.C., both local and federal, were tried in the federal district court.10 The 1970 Act created a court system “comparable to those in the States, separate and apart from the [federal court system].”11 And the Supreme Court has stated that the local court system was established in order “[to] handle criminal cases only under statutes that are applicable to the District of Columbia alone,” and, therefore, a defendant tried in this jurisdiction is “no more disadvantaged . than any other citizen of any of the 50 States who is tried for a strictly local crime.” Palmore v. United States, 411 U.S. 389, 407, 410, 93 S.Ct. 1670, 1681, 1682, 36 L.Ed.2d 342 (1973) (emphasis supplied). Thus, the Court has made it plain that the Court Reorganization Act contemplates two separate court systems, each administering a separate code.
Nevertheless, this court fails to consider this critical history of the Court Reorganization Act, and contrary to Pal-more, concludes that the two codes were generally intended to “mesh with each other.” It rests on the following three assertions.
First, it says:.
“The Federal Criminal Code embodied in Title 18 and the District of Columbia Code of Title 22. were both enacted by Congress and were intended to exist together. Johnson v. United States, 225 U.S. 405 [32 S.Ct. 748, 56 L.Ed. 1142] (1912).” (Court’s opinion at 1150.)
The court’s claim that the two codes were intended to “exist together,” and its citation to Johnson, the case from which those words were taken, is plainly misleading since Johnson stands for the proposition that the two codes are “separate instruments” that are not intended to mesh with each other. Johnson involved a challenge to the original D.C. Code, which was enacted in 1901,12 on the ground that its homicide provision did not allow juries to prohibit capital punishment in murder cases. The United States Criminal Code, which was enacted in 1909,13 did permit juries to nullify capital punishment. Johnson claimed that the U.S.Code was intended to modify the D.C.Code since the original D.C.Code, still in force at the time of Johnson’s case in 1912, provided that “so far as [future] acts [of Congress] may vary from or conflict with any provision contained in this code, they are to have effect as subsequent statutes and as repealing any portion of this act inconsistent therewith.” 14 The Court rejected this argument because “Congress certainly in enacting the [1901] District Code, recognized the expediency of separate provisions for the District of Columbia,” and “[h]aving definite territorial operation, [the U.S. and D.C. Codes] can exist together.” 225 U.S. at 418-419, 32 S.Ct. at 752, 753 (emphasis supplied). As a general principle, the Court concluded:
the effect of separation is important and necessarily had its purpose. The codes had in the main special spheres of operation and provisions accommodated to such spheres. 225 U.S. at 417, 32 S.Ct. at 752.
Thus, Johnson strongly undercuts this court’s conclusion that the two codes were intended to mesh. On the contrary, it indicates that long before Pal-more, indeed since the inception of the two codes, they have been viewed as separate and independent instruments. This court ignores the Johnson holding, and simply lifts two words — “exist together” — from the decision, and cites them wholly out of context.
The court’s second assertion is:
“We believe further that [the two codes] were intended to mesh with each other, and that they have been so *1163construed in the past. [Citations omitted.]” (Court’s opinion at 1150.)
The court relies solely upon some early eases in this Circuit which held that the federal conspiracy statute could charge conspiracies to violate the D.C.Code as well as conspiracies to violate the federal code.15 It implies that because this one section has been held to apply across the two codes, Congress generally intended them to mesh. The D.C.Code felony murder provision, however, has been in effect for over seventy years, and the court cites no case, nor have I been able to find any case, in which it has been applied to a federal offense.
Moreover, application of the federal conspiracy statute to local offenses filled an important need: conspiracies to violate the provisions of the D.C.Cdde would otherwise have gone unpunished, because prior to the Court Reorganization Act of 1970 16 the D.C.Code lacked a general conspiracy section. No such lacuna has ever existed with respect to the homicide sections of the two codes.17 Indeed, appellant was convicted under both the local felony murder provision, and the federal premeditated murder statute, for the same killing.
Finally, application of the federal conspiracy statute to local offenses raises no serious equal protection issues since the result is solely to allow punishment for those who conspire to violate the D.C. Code. In effect, Congress enacted a local conspiracy statute and placed it in the federal code. Since Congress has not punished such conspiracies differently under any other provision there is no potential constitutional infirmity. Application of the D.C.Code felony murder provision to U.S.Code offenses, on the other hand, raises a serious equal protection problem that will be discussed below.18
Finally, the court asserts:
“To adopt appellant’s construction would lead to an anomalous result, one that Congress could not conceivably have intended. If one [committed a killing] during the course of a robbery on the street in front of a bank, he could be prosecuted for felony murder under the D.C.Code, but if during the course of a robbery in a bank a killing occurred, that robber could not be prosecuted for felony murder under the D.C.Code.” (Court’s opinion at 1151.)
I assume the court is claiming that it would be anomalous to hold the D.C. felony murder statute applicable to all robberies committed in D.C. except bank robberies. Congress, however, has made it a federal crime — applicable in D.C. as well as every other jurisdiction — to commit a homicide in the course of any bank robbery.19 There is nothing anomalous about punishing, on the one hand, purely local robberies (and any homicides that occur in the course of their commission) under the D.C.Code, and, on the other hand, punishing those robberies and homicides that are of national concern under the U.S.Code, even if they all take place in the District of Columbia.
On the contrary, it is the court’s interpretation of the D.C. felony murder *1164statute, not appellant’s, that leads to an anomalous result: namely that Congress intended to punish homicides that occur in the course of a bank robbery more severely in D.C. than in the remainder of the country. The D.C. felony, murder statute, which the court holds applicable to federal bank robberies, carries a mandatory life sentence with parole eligibility only after twenty years,20 whereas the federal bank robbery statute’s felony murder provision carries a sentence of ten years to life imprisonment,21 with parole eligibility after one third of any sentence is served, but in no case beyond fifteen years.22
In sum, the court’s three assertions simply do not support its conclusion. Indeed, at least the first and third justifications appear to cut the other way. Moreover, the court ignores our opinion in United States v. Thompson, 147 U.S. App.D.C. 1, 452 F.2d 1333 (1971). There, appellant had been convicted of two U.S.Code violations in this jurisdiction, and was seeking release pending appeal. He argued that his petition for release should be governed by the federal bail statute.23 The government urged that it be judged under the harsher standards of the D.C.Code bail statute which applies to anyone “convicted of any criminal offense committed in the District of Columbia . in violation of an Act of Congress.”24 We held that this provision was intended to apply only to those convicted of D.C. Code offenses. Thus, the court’s decision in this ease violates the spirit, if not the holding, of Thompson.
B. EQUAL PROTECTION
Reading the D.C. felony murder statute to include U.S. felonies raises a serious equal protection issue that the court simply fails to confront.25 In the court’s view, Congress intended to punish someone who kills a federal marshal while escaping (or assisting another to escape) in the District of Columbia under the D.C.Code felony murder statute, as well as under the federal murder and escape statutes, whereas in every other jurisdiction Congress intended to punish exactly the same conduct solely under the two federal statutes, neither of which has an applicable felony murder *1165provision.26 As a result, Congress has imposed a mandatory sentence of twenty years to life in D.C. for the same conduct as to which it has imposed a sentence ranging from “any term of years” to a maximum of fifteen years to life in every other jurisdiction.27
In Thompson, supra, we held that when Congress establishes “discriminatory classifications affecting District residents” with respect to federal crimes, equal protection requires that “the justification offered must actually be convincing.” 452 F.2d at 1341 (emphasis in original). Yet this court does not suggest even a colorable legislative justification for imposing greatly disparate sentences for the same conduct.28 The simple fact — one that apparently eludes the court — is that the only reason to apply the D.C.Code to conduct that has already been made criminal under the U.S.Code is to increase sentences solely for those who commit their crimes in this jurisdiction.29
C. UNITED STATES v. CANTY
Even if the D.C. felony murder statute may validly include federal offenses, our decision in United States v. Canty, 152 U.S.App.D.C. 103, 469 F.2d 114 (1972), which the court ignores, requires dismissal of appellant’s D.C.Code felony murder conviction.30 In Canty, the defendant committed a bank robbery while armed. He could have been charged with violating section “d” of the federal bank robbery statute (bank robbery while armed),31 which carries a twenty-five year maximum sentence. Instead, he was charged with simple bank robbery under the federal statute,32 which carries a twenty year maximum sentence, and assault with a deadly weapon under the D.C.Code,33 which carries a ten year maximum. In *1166sum, by going outside the federal bank robbery statute, and charging in part under the D.C.Code, the government was able to increase the defendant’s potential maximum sentence from 25 to 30 years. We vacated the D.C.Code assault conviction, holding that the government is prohibited from “venturing outside the federal scheme,” and thereby “circumvent[ing its] carefully crafted hierarchy of penalties.” 469 F.2d at 128.
In the present case, appellant was charged with one count of premeditated murder under the federal code, which carries a mandatory sentence of 15 years to life, and also one count of felony murder under the D.C.Code, which carries a mandatory sentence of 20 years to life. The federal homicide statute, like the federal bank robbery statute in Canty, is carefully subdivided to cover varying degrees of the same offense; it includes two degrees of murder, two types of manslaughter, and attempted murder and manslaughter, and each crime carries a different penalty. Hence, the only reason for the government to go outside this “carefully crafted federal scheme,” and charge under the D.C. Code, was to increase appellant’s minimum sentence by at least five years.34 Canty prohibits this.35
The court affirms appellant’s D.C. Code felony murder conviction without discussion of (1) a grave equal protection problem, (2) the Court Reorganization Act, (3) the Supreme Court’s decision in Patmore, and (4) our decisions in Thompson and Canty — all of which require dismissal of the D.C.Code felony murder conviction. Moreover, it does so gratuitously since appellant was also convicted of premeditated murder under the federal homicide statute for the same killing, and the sentences on the D.C. and federal murder convictions were imposed concurrently. In the face of all this, one must wonder why this court pursued the course it did. I think we can glean some light from parts V and VI of its opinion.
JI
In part V, the court concludes that it has the discretion to vacate appellant’s federal premeditated murder conviction under the Hooper doctrine.36 Hooper is a judicially created doctrine of appellate discretion allowing vacation of a conviction raising “an issue not governed by controlling precedent,” when the sentence imposed on it is concurrent with a sentence on a valid conviction. 432 F.2d at 606. In this casé, the sentence on the federal premeditated murder conviction was concurrent with the sentence on the D.C. felony murder conviction, and the court found that the federal conviction “raises serious issues.” 37 in part VI, the court holds that it is required to vacate the federal conviction for assisting escape because it was the underlying felony of the D.C. felony murder conviction, and therefore merges into it.
Thus, by affirming the D.C.Code felony murder conviction, the court believes that it is able to vacate both of appellant’s federal convictions. This affirm-*1167anee notwithstanding, I think that it was an unwise use, if not an abuse, of discretion to vacate the federal murder conviction, and that it borders on the ridiculous to merge the federal assisting escape conviction into the local felony murder conviction.
A. THE FEDERAL PREMEDITATED MURDER CONVICTION
Appellant attacked this conviction claiming that application of the D.C. statute — which requires a defendant to establish his plea of insanity by a preponderance of the evidence — to federal offenses tried in this jurisdiction is a denial of equal protection because in every other federal trial the prosecution must prove sanity beyond a reasonable doubt.38 Acknowledging the power of this argument, the court vacates the federal murder conviction for the reason given in Hooper that “[i]t better serves the general interest of the administration of justice if the court limits its resources to the determination of those questions and cases that must be decided, especially in light of the ever-mounting docket that besets this and other appellate courts.” 432 F.2d at 606. Hooper states, however, that a conviction raising a difficult issue should be vacated only when “no present public interest or need is furthered” by resolution of the issue. The issue that triggered the use of the Hooper doctrine in this case is whether the D.C. burden of proof statute can be applied to federal offenses. That issue is bound to recur frequently. By postponing its resolution, and thereby allowing application of the D.C. statute governing burden of proof to trials in our federal district court, we undercut both justice and efficiency. Since many convictions will be secured under this questionable statute, there will be strong incentive for upholding it in order to avoid reversals; and, if wholesale reversals are ultimately required, we will suffer the burden of many time-consuming retrials. The simple fact — which again appears to elude the court — is that when the constitutionality' of a statute of general application is called into question, justice and fairness require an expeditious resolution.
Hooperizing appellant’s federal murder conviction can perhaps be viewed as indicative of a strong, albeit misguided, commitment to judicial restraint. That same restraint, however, is not evidenced in other parts of the opinion. Appellant also challenged his grand and petit juries, claiming in part that “young people” were inadequately represented in violation of the federal jury selection statute.39 Although the court denies this claim because it was not timely raised in the trial court, it proceeds to expound its view that “young persons” should not be considered a cognizable group for jury composition, and concludes:
We have thought it useful to discuss problems presented by appellant’s thesis even though, in view of the lack of timely objection, we do not decide this matter on the merits. (Court’s opinion at 1150.)
The court reached out for this issue on an admittedly “inadequate record,” and despite the lack of controlling precedent in this jurisdiction and a decision of a Sister Circuit holding “youth” to be a cognizable class for jury selection as a matter of constitutional law.40
Thus, contrary to Hooper, and on an issue that was clearly not before it, the court devoted its “time and energies to the research, and opinion writing, incident to appropriate determination of an issue not governed by controlling precedent.” 432 F.2d at 606.
*1168B. THE FEDERAL ASSISTING ESCAPE CONVICTION
Since the sentence imposed for this federal conviction was consecutive to the sentence for the D.C. felony murder conviction, the court was unable to Hooperize it in order to avoid deciding the constitutionality of the D.C. burden of proof statute governing insanity as it applies to federal offenses. The court does find, however, that the D.C. “charge of felony murder [while assisting an escape] includes every essential fact element of the [federal assisting escape] charge,” and concludes, therefore, that there has been a “merger between the felony alleged as part of the felony murder,” and vacates the federal assisting escape conviction. (Court’s opinion at 1158.)
The government itself pointed out in its petition for rehearing41 that this merger was predicated on a wholly erroneous understanding of the felony murder doctrine.42 At common law, homicides were divided into two categories, murder and manslaughter, with murder requiring a showing of “malice.” Any homicide committed in the course of a felony was considered murder because malice could be implied from the commission of the felony.43 When homicides were further subdivided by statute into first degree murder, second degree murder and manslaughter,44 the doctrine of felony murder was preserved, and the underlying felony was viewed as providing the “premeditation” and “deliberation” otherwise required for first degree murder, as well as malice, where necessary.45
Given this rationale for the felony murder doctrine, it strains credulity to hold that the underlying felony merges into the felony murder.46 The statute proscribing the underlying felony — robbery, for example — is designed to protect a wholly different societal interest from the felony murder statute, which is intended to protect against homicide.47 *1169The underlying felony is an essential element of felony murder only because without it the homicide might be second degree murder or manslaughter.48 Clearly, neither manslaughter nor second degree murder merges with any other felony like robbery or assisting a prisoner to escape.49
This analysis undoubtedly accounts for the court’s failure to cite a single case suggesting that a felony murder and the underlying felony merge.50 Indeed, it explains why this court has affirmed both the underlying felony and the felony murder in countless cases.51
In short, to avoid deciding whether the D.C.Code burden of proof statute governing the insanity plea can be applied to U.S.Code offenses, the court affirms appellant’s D.C.Code felony murder conviction, and vacates his U.S.Code convictions for premeditated murder and assisting escape. Thus far, I have tried to show that well-settled judicial doctrine required the court to do the opposite of what it has done: namely, to vacate the D.C.Code felony murder conviction, and decide if the application of the D'.C. burden of proof statute to appellant’s federal offenses was proper.
The court’s failure to adhere to established legal doctrine was by no means inconsequential. Even if the D.C.Code burden of proof provision was properly applied to appellant’s federal offenses, the course taken by the court increased his minimum sentence by more than three years.52 And, if the burden of proof could not be applied to his federal offenses, appellant is entitled to a new trial on the insanity phase of his convictions53 under a more favorable burden of proof.54
The court’s tortured course was not only prejudicial to appellant, it was also of no avail. In the following section I will show that even if the court had *1170been correct in taking each of the steps discussed so far, it was still required to decide whether the D.C. burden of proof statute could apply to federal offenses.
Ill
In Part III, the court upholds the application of the insanity burden of proof statute to D.C.Code offenses, and also decides “to put to one side [the questions of] whether those provisions were intended to or can have application to a prosecution in the District Court of [a federal offense].” (Court’s opinion at 1153.) It is able to do this, it believes, because it has vacated appellant’s federal convictions.
Notwithstanding these vacations, I believe the court was required to consider whether the D.C. burden of proof statute could apply to federal offenses for two reasons: first, because it has wittingly or unwittingly approved the statute’s application to a federal offense by affirming appellant’s D.C. felony murder conviction for a homicide committed in the course of a federal offense; and second, because if the D.C. burden of proof statute cannot constitutionally be applied to federal offenses, the whole statute, including' its application to D.C. Code offenses, fails.
A. D.C.CODE FELONY MURDER WHILE COMMITTING A FEDERAL OFFENSE
The court affirms appellant’s D.C. Code felony murder conviction on the ground that the D.C. burden of proof statute can be applied to local offenses. The underlying felony of the felony murder conviction, however, was the federal offense of assisting a prisoner to escape; without proof of this federal offense, the felony murder conviction necessarily fails.55 Thus, it is clear that on this U.S.Code offense appellant had the burden under the D.C. statute to prove his sanity by a preponderance of the evidence.56
B. BASIC PRINCIPLES OF EQUAL PROTECTION
Even without any federal convictions before it, the court was required to consider whether the D.C. burden of proof statute could apply to U.S.Code offenses. Appellant argued first that the statute in plain terms applies to “any criminal proceeding in the District Court,” which obviously includes the trial of federal offenses;57 on this point, the government agreed.58 Second, he claimed that such a legislative classification is either underinclusive59 because it does not apply to federal crimes tried in other jurisdictions, or overinclusive60 because it *1171does not apply exclusively to D.C.Code offenses, and that for either reason, it is a denial of equal protection.
In the face of this challenge, the court’s decision to “put to one side” the applicability of the D.C. burden of proof statute to federal offenses evidences a misunderstanding of basic equal protection analysis. By claiming that the D.C. burden of proof statute is overinclusive because it applies to federal offenses tried in the District of Columbia, appellant acknowledges that Congress might well be able to enact a burden of proof statute limited to local offenses,61 unless of course it would be a violation of due process.62 Congress, however, has chosen to pass a different statute. And by failing to consider the overinclusive aspect of that statute, this court has decided to “make a new law, not to enforce an old one”; and “this,” the Supreme Court has held, “is no part of our duty.” 63 Obviously, every equal protection challenge could be rejected if a court is willing to ignore the existing statutory classification.64
By failing to address the equal protection issue, the court forces us to choose between two unacceptable alternatives. Either we can read the D.C. burden of proof statute to apply only to local offenses, or we can hold that its application to federal offenses is not a denial of equal protection. Limiting the statute to local offenses is not only contrary to its language65 and legislative history,66 *1172but also leads to the imposition of two different burdens of proof on the issue of sanity67 when federal and local offenses are joined in federal district court.68
On the other hand, holding that the statute may apply to U.S.Code offenses tried in this jurisdiction requires us to find that the “justification offered” by Congress for limiting its application to federal offenses tried in the District is “actually convincing.”69 Thompson, supra, 452 F.2d at 1341. The justification offered70 was our decision in Bolton v. Harris, 130 U.S.App.D.C. 1, 395 F.2d 642 (1968), where we held that the government could not automatically commit for long term treatment those found not guilty by reason of insanity; first, it had to prove by a preponderance of the evidence that they were mentally ill and dangerous at the time of commitment.71 Congress feared that Bolton would allow “dangerous criminals, particularly psychopaths to win acquittals of serious criminal charges on grounds of insanity by raising a mere reasonable doubt as to their sanity and then to escape hospital commitment because the government is unable to prove their insanity following acquittal by a preponderance of the evidence.”-72 This reasoning rests on a misapprehension about how the insanity defense has been administered in this jurisdiction.73 Even if it were a reason*1173able concern, however, it is inadequate as a justification for a classification distinguishing between D.C. and other jurisdictions. In D.C. there is a statutory-procedure, applicable to both local and federal offenses, that permits post-trial confinement of those found not guilty by reason of insanity.74 No such statute applies to federal offenses tried in other jurisdictions, where an accused found not guilty by reason of insanity is released.'75 He may, of course, be committed pursuant to a state civil commitment statute,76 but no state permits long term civil commitment unless the state establishes mental illness by at least a preponderance of the evidence.77 Therefore, there is no justification, let alone a convincing one, for singling out the District of Columbia, and applying a different burden of proof on federal offenses.
Thus, the court in the present case— by failing to consider the equal protection issue raised by the D.C. burden of proof statute — has forced us to choose in subsequent cases between two wholly unacceptable choices.
IV
The court finally affirms appellant’s D.C.Code felony murder conviction and his D.C.Code robbery convictions, all of which rested on the application of the D.C.Code provision placing .the burden *1174on the defendant to establish his insanity defense by a preponderance of the evidence. It holds that the burden of proof statute is neither a denial of equal protection nor due process.
A. EQUAL PROTECTION
The court summarily concludes that the application of a burden of proof standard for D.C.Code offenses different from that for federal offenses is not a denial of equal protection because “[i]n enacting local criminal statutes [for the District of Columbia], Congress need not hew to the same path it elects in defining criminal offenses of nationwide applicability.” (Court’s opinion at 1153.) Rather than resting upon this sort of ipse dixit, it seems to me that equal protection requires some consideration of the reasons that would permit the same legislature to impose a burden of proof for the trial of D.C. crimes that is different from the one applied in the trial of federal crimes.78
While I am troubled that the court fails to conclude that Congress is barred from enacting a different burden of proof statute for D.C.Code offenses, I am even more concerned that the court thinks the question unworthy of serious consideration. The District of Columbia, which is over seventy percent black,79 is wholly disfranchised. Traditionally, this would call forth a higher standard of equal protection scrutiny.80 In this jurisdiction, however, it appears that it does not.
B. DUE PROCESS
The court also rejects appellant’s argument that any statute, irrespective of application, requiring a defendant to prove his insanity is a denial of due process. Appellant relies on In Re Winship, 397 U.S. 358, 90 S.Ct. 1068, 25 L.Ed.2d 368 (1970), which held that the government must “pro[ve] beyond a reasonable doubt . . . every fact necessary to constitute the crime,” and claims that sanity is such a fact. In rejecting this contention, the court advances several arguments, reasons, and cases, which I shall examine in some detail. First, however, it is helpful to place the question in its proper historical context.
In 1895, Justice Harlan writing for a unanimous Supreme Court reversed a murder conviction because the trial court had instructed the jury that “the burden of proof of the insanity rests with the defendant.” Davis v. United States, 160 U.S. 469, 477, 16 S.Ct. 353, 354, 40 L.Ed. 499. The Court found that sanity was an “essential fact” of the crime of murder, and that the burden was on the prosecution “to show beyond a reasonable doubt the existence of every fact necessary to constitute the crime charged.” Id. at 493, 16 S.Ct. at 360.
In 1952, the Court upheld the constitutionality of an Oregon statute requiring the defendant to prove his insanity beyond a reasonable doubt, Leland v. Oregon, 343 U.S. 790, 72 S.Ct. 1002, 96 L. Ed. 1302, and indicated that Davis was not a constitutional holding, “but only the rule to be followed in federal courts.” Id. at 797, 72 S.Ct. at 1007. Justices Frankfurter and Black dissented, arguing that, by definition, a homicide without sanity is not a murder. They noted *1175that “[t]his duty of the State of establishing every fact of the equation which adds up to a crime, and of establishing it to the satisfaction of a jury beyond a reasonable doubt is the decisive difference between criminal culpability and civil liability.” Id. at 805, 72 S.Ct. at 1011. After Leland, we continued to apply the “beyond a reasonable doubt” standard in this jurisdiction.81
Finally, in 1970, in Winship, which involved an adjudication of juvenile delinquency,82 the Court went beyond the factual context of the case before it to hold:
Lest there remain any doubt about the constitutional stature of the reasonable-doubt standard, we explicitly hold that the Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged. 397 U.S. at 364, 90 S.Ct. at 1073 (emphasis supplied).
Due to the intentionally broad holding of Winship, the question for this court in deciding whether the D.C. burden of proof statute violates due process is whether Winship overrules. Leland sub silentio 83 — that is, whether “sanity” is a “fact necessary to constitute the crime.” Davis held that sanity was such a fact. Indeed, it is at least instructive that in setting out its holding the Winship Court returned to the Davis formulation of “every fact necessary to constitute the crime.” This court fails to mention Winship’s plain adoption of the Davis formulation.
The court offers nine justifications for its conclusion.
First:
“Winship involved proof of facts — ‘the occurrence of an event’ — while insanity deals with proof of ‘mental condition and propensity.’ United States v. Brown, [155 U.S.App.D.C. 402, 478 F.2d 606, 609 (1973)].” (Court’s opinion at 1155.)
On the contrary, sanity, as Davis clearly indicates, has always been a factual question, and nothing else. The panel cites no cases, and I believe there are no cases, suggesting that sanity, unlike the act in question, is not a factual issue.
The court’s reliance on United States v. Brown is misplaced. When Brown refers to “mental condition and propensity,” it is explicitly describing “dangerousness,” which is, presumably, a present status indicative of future behavior.84 Insanity, on the other hand, involves the same sort of factual inquiry needed to determine premeditation, deliberation, and intent, all of which are clearly covered by Winship 85
Second:
“The Supreme Court’s opinion in Win-ship cited with approval a group of prior decisions, including Leland v. Oregon.” (Court’s opinion at 1155.)
The Court did cite Leland once, (as part of a string citation that included Davis), but only to support a proposition that can hardly comfort my brethren:
Expressions in many opinions of this Court indicate that it has long been assumed that proof of a criminal *1176charge beyond a reasonable doubt is constitutionally required. 397 U.S. at 362, 90 S.Ct. at 1071.
Immediately thereafter, the Court quotes approvingly from the Leland dissent:
[i]t is the duty of the Government to establish . . . guilt beyond a reasonable doubt. This notion — basic in our law and rightly one of the boasts of a free society — is a requirement and a safeguard of due process of law in the historic, procedural content of “due process.” 397 U.S. at 362, 90 S.Ct. at 1071, quoting 343 U.S. at 802-803, 72 S.Ct. 1002 (elipses in original).
Then, further down the page, the Win-ship Court had this to say about Davis:
In Davis a murder conviction was reversed because the trial judge instructed the jury that it was their duty to convict when the evidence was equally balanced regarding the sanity of the accused. This Court said: “On the contrary, he is entitled to an acquittal of the specific crime charged if upon all the evidence there is reasonable doubt whether he was capable in law of committing crime. . No man should be deprived of his life under the forms of law unless the jurors who try him are able, upon their consciences, to say that the evidence before them ... is sufficient to show beyond a reasonable doubt the existence of every fact necessary to constitute the crime charged.” 397 U. S. at 362-363, 90 S.Ct. at 1072, quoting in part 160 U.S. at 484, 493, 16 S.Ct. 353 (elipses in original).
These quotations are the heart of the Court’s ruling on the burden of proof standard. They leave precious little doubt that Winship intended to include sanity within its constitutional holding.86
Third:
“The essential elements of the charge of felony murder do not include proof of sanity.” (Court’s opinion at 1155/)
The D.C. burden of proof statute applies to all crimes, not just felony murder. Thus, the question before the court was whether sanity is generally an element of criminal behavior. Indeed, the court’s summary affirmance of the application of the new burden of proof statute to appellant’s robbery convictions indicates that it was not concerned with the elements of a particular offense in deciding the statute’s constitutionality.
Even if it was appropriate to decide the constitutionality of the statute by considering a particular offense, felony murder was an especially poor selection. Its statutory definition, unlike that of most crimes, requires the perpetrator to be “of sound memory and discretion.” 22 D.C.Code § 2401. The court fails to consider this statutory definition when it discusses the constitutionality of the burden of proof statute as it applies to felony murder.
Earlier in its opinion, however, the court rejected appellant’s argument that the trial court’s failure to instruct the jury that “the government must prove [sound memory and discretion]” was error. The court suggested that this issue is “well-settled” against appellant be*1177cause several cases87 have held that sound memory and discretion need not be alleged in the indictment. The cases cited by the court, however, all rely upon Hill v. United States, 22 App.D.C. 395 (D.C.Cir.1903), which, while holding that “sound memory and discretion” need not be alleged in the indictment, also noted with approval that the trial judge had instructed the jury that they must find “beyond all reasonable doubt that the defendant . . . was a person of sound memory and discretion,” and that the government “establish [ed] the fact of sanity beyond a reasonable doubt.” 22 App.D.C. at 408. Thus, whether the government need prove “sound memory and discretion” in a felony murder case is hardly “well-settled.” 88
Thus, even if we were to read Win-ship not to include sanity within its holding, it might still be argued that once Congress chooses to make sanity a part of the statutory definition — as it has with felony murder — the government must prove the existence of this element beyond a reasonable doubt.
Fourth:
“Here [unlike Davis'], the charge is felony murder, not common law murder, and accordingly, no proof of premeditation, deliberation, and malice is required.” (Court’s opinion at 1156.)
While this distinction between Davis and the present case is true, it is also irrelevant. Davis, of course, has never been limited to premeditated murder eases.89
Moreover, the court’s distinction between premeditated murder and felony murder cuts in the wrong direction, as the Supreme Court in Leland, and this court in United States v. Brawner, 153 U.S.App.D.C. 1, 471 F.2d 969 (1972) (en banc), seem to suggest. When the prosecution must prove “premeditation and deliberation” beyond a reasonable doubt, and the jury is allowed to consider the evidence of the defendant’s mental illness in deciding whether the government has satisfied its burden on these cognitive factors, the government is required to make a significant showing on mental state and intent. Thus, in setting out the facts in Leland, the Court was careful to note that the trial judge had instructed the jury that the state had the burden of proving beyond a reasonable doubt:
premeditation, deliberation, malice and intent, . . . [and] that the evidence adduced during this trial to prove defendant’s insanity shall be considered ... in regard to the ability of the defendant to premeditate, form a purpose, to deliberate, act willfully, and act maliciously. 343 U.S. at 794-795, 72 S.Ct. at 1005.
And in Brawner, in explaining why the jury should be allowed to consider the evidence of mental illness on the question of intent, we made specific reference to the effect of the recently enacted D.C. statute governing the burden of proof on insanity pleas:
[T]o the extent that the [D.C. burden of proof statute] leads to a conviction of first degree murder when the evidence is in equipoise on the issue of insanity, there would be an additional miscarriage of justice if the evidence were not available for consideration as *1178raising a reasonable doubt on the issue of premeditation and deliberation. 471 F.2d at 1002.
Appellant in this case was made to suffer precisely this “additional miscarriage of justice,” although the court here makes no mention of it. His trial was conducted under the now defunct Fisher90 doctrine, which prohibited the jury from considering the evidence of a defendant’s mental illness in deciding whether the requisite mental state for murder existed. Indeed, the miscarriage of justice was even greater here since the trial court bifurcated appellant’s trial over his objection; thus, the jury was wholly cut off from the evidence on appellant’s mental state, and was unable to consider it even in the informal sense of jury notification tolerated in this jurisdiction 91 It is notorious that juries consider evidence of mental disorder to return verdicts for lesser degrees of homicide 92 as a compromise between a conviction of first degree murder and an acquittal by reason of insanity.93
Appellant challenged the trial court’s action bifurcating the trial over his objection. This court simply holds that bifurcation is largely within the “discretion” of the trial court; it cites no case permitting bifurcation over the objection of the defense.94 More importantly, it does not consider how this problem is affected by the jury’s widely known reluctance to accept an insanity plea, which is further aggravated by the fact that the defendant had to prove his insanity.
Once again, then, even if we were to hold that due process does not generally require the prosecution to prove sanity beyond a reasonable doubt, it might well be argued that appellant was denied due process in this case because the jury was totally barred from weighing the evidence of his mental condition as bearing on the degree of culpability.
Fifth:
“If [sanity were an essential element of felony murder], the Government would be required to produce evidence establishing sanity beyond a reasonable doubt as part of its direct case, before the defendant introduced an iota of testimony, and that is not and never has been the law. Davis in effect confirms [this] observation . . . for otherwise Davis would have required the prosecution to have proved sanity beyond a reasonable doubt as part of its direct case.” (Court’s opinion at 1155, 1156.)
Davis explicitly holds that sanity is a “fact essential to constitute the crime,” and that “[t]his view is not at all inconsistent with the” requirement that the government need not satisfy its burden until the accused produces “some evidence” of insanity.95 160 U.S. at 485-*1179486, 16 S.Ct. at 357. Thus, the court in the present ease completely misstates Davis.
Sixth:
“In determining whether Leland v. Oregon is modified or overruled by In Re Winship, consideration should be given to the more recent case of Lego v. Twomey, 404 U.S. 477, 92 S.Ct. 619, 30 L.Ed.2d 618 (1972), in which the Court held that it was consistent with due process to determine the volun-tariness of a confession by a preponderance of the evidence rather than by proof beyond a reasonble doubt.” (Court’s opinion at 1155.)
Winship, in plain terms, does not apply to the burden of proof required in testing the voluntariness of a confession. Thus, the question in Lego was whether to extend Winship, not whether to apply it. The Court decided not to extend it because “a voluntariness hearing has nothing whatever to do with improving the reliability of jury verdicts.” 404 U.S. at 486, 92 S.Ct. at 625. The insanity defense, on the other hand, has a great deal to do with “the reliability of jury verdicts.”
Seventh:
“[In United States v. Braver, 450 F. 2d 799 (1971), the Second Circuit] held that placing the burden of proving inducement [as part of an entrapment defense] on the defendant does not constitute a denial of due process.” (Court’s opinion at 1155.)
In the Second Circuit the defense of entrapment is split into two elements: governmental inducement and the criminal propensity of the defendant. The Braver court indicated, and the Supreme Court has subsequently reaffirmed,96 that if the prosecution proves propensity, the entrapment defense fails, irrespective of a showing of governmental inducement. Thus, inducement obviously negates no element of the crime since the crime can be proved notwithstanding such a showing. Propensity, on the other hand, bears directly on criminal intent; if propensity is not proved, proof of the crime fails. On propensity, as Braver noted, and as this court fails to mention, the government has the burden of proof beyond a reasonable doubt.97
Eighth:
“In Phillips v. State, [86 Nev. 720, 475 P.2d 671,] the Supreme Court of Nevada rejected the argument that In Re Winship changes the concept [of Leland] that one asserting the affirmative defense of insanity must prove insanity by a preponderance of the evidence.” (Court’s opinion at 1156.)
This naked holding of a state supreme court, unsupported by any analysis or reasoning, does not lend much weight to the court’s conclusion. For what it is worth, however, the Nevada opinion explicitly rests on the “well-settled” rule that “insanity is an affirmative proposition.” 98 In this jurisdiction, we have repeatedly held that the insanity plea is more than an affirmative defense, and that at times the interest of justice requires the court or prosecution to raise the issue even over the objection of the defendant.99 In fact, the burden *1180of proof statute in question provides that the defendant must prove his insanity “regardless of who raises the issue.” The court also notes that the Supreme Court denied certiorari in the Nevada ease, with only two Justices dissenting.100 The Supreme Court itself, however, has repeated countless times that a denial of certiorari “carries with it no support of the decision in that case, nor of any of the views in the opinion supporting it.” Agoston v. Pennsylvania, 340 U.S. 844-845, 71 S.Ct. 9, 95 L.Ed. 619 (1950) (opinion of Frankfurter, J.j.
Ninth:
“[S]anity is not one of the elements of felony murder but lack of sanity may be interposed as a defense.” (Court’s opinion at 1155.)
Throughout its opinion the court seems to suggest that because we discuss the question of criminal responsibility under the rubric of the “insanity defense,” sanity is not an element of the crime. It would be hollow, to say the least, for us to look at the label attached to the question at issue in deciding if Winship was meant to apply. Such an approach would allow the state to require a defendant to prove his “alibi defense” by a preponderance of the evidence. Compare Stump v. Bennett, 398 F.2d 111 (8th Cir. 1968) (en banc) (violation of due process to require defendant to prove alibi defense).
Thus, the cases, propositions, and arguments marshalled by the court fail to support its conclusion that Winship does not require the government to prove sanity beyond a reasonable doubt. On the contrary, almost without exception, they support precisely the opposite conclusion.
V
The issues in this case are critical to the fair administration of justice — for the prosecution101 as well as the defense. Moreover, they are central to the proper functioning of the new relationship between the federal criminal system and the recently created D.C. system. Because of the importance of these matters, it was necessary in setting forth my views to show that the opinion of the court ignored controlling precedent,102 misstated,103 misrepresented104 and misapplied105 several authorities, and manifested a failure to understand basic principles of equal protection analysis 106 and the felony murder doc-triné.107 It was my hope and expectation that the court would offer a reasoned response fully ventilating all of these issues. Regrettably, the only response was an admission from Judge Leventhal that the issues are “arguable” but too “narrow” to merit en banc consideration.

. See cases cited in court’s op. at 1150-1151. The rationale of these cases is that the U.S. Code conspiracy statute applies to those who conspire to commit “any offense against the United States,” and that a violation of the D.C.Code is not a crime “against the District, but against the United States.” United States v. Cella, 37 App.D.C. 423, 426 (1911), quoting Metropolitan R. Co. v. District of Columbia, 132 U.S. 1, 10 S.Ct. 19, 33 L.Ed. 231 (1889). But cf. P.L.No.91-358, § 172 (1970), codified at 28 U.S.C. § 1363 (“For purposes of this chapter, references to the laws of the United States or Acts of Congress do not include laws applicable exclusively to the District of Columbia.”).

. If the D.C.Code felony murder statute were limited to local offenses, those homicides falling within the explicit coverage of the U.S. Code could be prosecuted thereunder, and all other homicides occurring in D.C. could be prosecuted under the D.C.Code.

. 23 D.C.Code §§ 1325(c), 1331(2) (1973) (emphasis supplied).
. The court does consider a different equal protection argument, raised by appellant, to the effect that the D.C.Code felony murder statute is a denial of equal protection because it applies to homicides committed during “any offense,” whereas the U.S.Code felony murder provision, applicable in “the special maritime and territorial jurisdiction” of the United States, is limited to four felonies — rape, arson, burglary and robbery. The court rejects this argument, apparently relying upon the following analysis: (1) Virginia could enact a felony murder statute that applies to all homicides, including those committed during a federal offense; (2) Congress, legislating for the District of Columbia, has the same powers as the Virginia legislature; (3) therefore, the D.C. felony murder statute is valid.
This syllogism indicates that the court misunderstands appellant’s equal protection challenge. In the hypothetical constructed by the court, the Virginia legislature enacted a single felony murder statute. The gravamen of appellant’s claim, on the other hand, is that Congress lacks adequate justification for enact-ting two different felony murder statutes, one for D.O., and one for the special maritime and territorial jurisdictions.
Although I am not persuaded by the court’s analysis, I do agree with its conclusion that this particular equal protection claim is without merit. The federal maritime and territorial jurisdiction is limited to “the high seas,” “forts,” “U.S. aircraft,” etc. 18 U.S.C. § 7 (1970). For these areas Congress has enacted a skeletal set of substantive criminal provisions, and therefore a limited felony murder statute. For D.C., however, Congress has enacted a broad code of offenses to deal with a more complex set of criminal problems, and therefore has also enacted a wider-reaching felony murder statute. Accordingly, there is no denial of equal protection. See Coleman v. United States, 118 U.S.App.D.C. 168, 334 F.2d 558, 565 (1964). Compare United States v. McDonald, 156 U.S.App.D.C. 338, 481 F.2d 513, 518 (1973) (Bazelon, C. J„ dissenting).
. Compare 18 U.S.C. § 2113(e) (1970) (felony murder provision for homicides committed during bank robberies).
. Under the D.C.Code, the sentence for felony murder is twenty years to life imprisonment. 22 D.C.Code § 2404. The same homicide, if charged under the U.S.Code, would either be: (1) first degree premeditated murder, which carries a sentence of fifteen years to life, 18 U.S.C. §§ 1111, 4202; (2) second degree murder, which is punishable by any term of years to life imprisonment, 18 U.S.C. § 1111, with parole eligibility after one third of any sentence but in no case more than fifteen years, 18 U.S.C. § 4202; or (3) voluntary manslaughter, which carries a maximum sentence of ten years, 18 U.S.C. § 1112, with parole eligibility after one third of any sentence. 18 U.S.C. § 4202. See p. 1168 & n. 45 infra.
. To the extent the court relies on the argument that the Virginia legislature could include federal offenses in its felony murder statute, therefore Congress can include them in the D.C. felony murder statute, see note 25 supra, its reliance is misplaced. If Congress is to penalize a crime of nationwide applicability more severely in this jurisdiction than in every other state, it needs a strong justification. Thompson-, supra. The analagous situation with respect to the Virginia legislature would be if it punished robbery by a ten year sentence in every county in the state save one — which, incidentally, was not represented in the state legislature — and in that county it imposed a twenty year sentence. See also pp. 1173-1174 infra.
. A sharply divided Supreme Court, relying on the doctrine of “separate sovereigns,” held that a state could impose a greater sentence than Congress for conduct that it proscribed by the federal code, and that a prosecution under the U.S.Code does not bar a subsequent state prosecution. Bartkus v. Illinois, 359 U.S. 121, 79 S.Ct. 676, 3 L.Ed.2d 684 (1959); Abbate v. United States, 359 U.S. 187, 79 S.Ct. 666, 3 L.Ed.2d 729 (1959). However, we have explicitly recognized that the doctrine of separate sovereigns “has no application here, since the [federal] statute and the District of Columbia Code have both been enacted by the same sovereign — the federal government.” United States v. Canty, 469 F.2d 114, 128-129 n. 20 (1972) and cases cited therein. See also Waller v. Florida, 397 U.S. 387, 90 S.Ct. 1184, 25 L.Ed.2d 435 (1970) (prosecution under municipal ordinance bar- to subsequent prosecution under state statute since state and municipality are same sovereign).
. Canty was informed largely by equal protection considerations similar to those discussed in section IB supra, although it did not explicitly rest on that ground.
. 18 U.S.C. § 2113(d) (1970).
. 18 U.S.C. § 2113(a) (1970).
. 22 D.C.Code § 502 (1973).
. Indeed, appellant’s sentence could have been increased by considerably more than five years since what might otherwise be second degree murder or manslaughter under the U.S. Code could be first degree felony murder under the D.C.Code. See note 27 supra.
. If the D.C.Code felony murder provision validly includes federal offenses, it must be applied only to homicides not otherwise covered by the U.S.Code in order to avoid violating Canty. For example, if in the course of an escape a felon kills a federal marshal, that killing would not come within the coverage of the D.C.Code felony murder provision since there is a federal statute covering the killing of marshals. On the other hand, if in the course of an escape the felon kills a bystander, a co-felon or someone else not covered by a federal homicide provision, that homicide would fall within the D.C.Code felony murder statute.

. Different felony murder statutes require varying degrees of volition ranging from intentional (although not premeditated) homicide to absolute liability for any homicide occurring during certain “dangerous” felonies. See Arent & MacDonald, supra note 42 at 293-305; Wechsler & Michael, supra note 44 at 713-717.
The D.C. felony murder statute for example, requires that a homicide committed in the course of any felony except rape, arson, burglary or robbery, be “purposeful” [i. e., “intentional” — Collazo v. United States, 90 U.S. App.D.C. 241, 196 F.2d 573, 578 (1952)] for it to be first degree murder. Thus, without the felony murder doctrine, these slayings, if not premeditated, would likely be second degree murder, or perhaps voluntary manslaughter.
Homicides committed during rape, arson, burglary and robbery are felony murders even when committed “without purpose so to do.” Hence, these killings might otherwise be any level of homicide, including involuntary manslaughter, or even possibly a non-criminal killing. See Coleman v. United States, 111 U.S.App.D.C. 210, 295 F.2d 555, 559-561 & 565-566 (1961). The “absolute liability” limits of the D.C. felony murder statute have not as yet been judicially determined. Fuller v. United States, 132 U.S.App.D.C. 264, 407 F.2d 1199, 1229 (1968). Compare People v. Stamp, 2 Cal.App.3d 203, 82 Cal.Rptr. 598 (1969), with American Law Institute, Model Penal Code § 201.2, and tentative draft #9, comment 4 to § 201.2.
. A merger traditionally takes place when the greater offense contains all of the elements of- — and protects the same interest as— the lesser offense. For example, an assault merges into an assault with a deadly weapon, and an assault with a deadly weapon merges into armed robbery. See United States v. Johnson, 155 U.S.App.D.C. 28, 475 F.2d 1297 (1973); United States v. Benn, 155 U.S.App.D.C. 180, 476 F.2d 1127 (1972, as amended Mar. 8, 1973). See also note 47 infra.
. When the interest protected by the underlying felony is not distinct from that protected by the homicide, the doctrine of felony murder is inapplicable. Otherwise, all voluntary *1169homicides would be felony murders because an assault always precedes the homicide. But the assault, since it protects the same interest as the completed homicide, merges into the homicide. See Arent & MacDonald, supra note 42 at 298-99.
. Second degree murder and manslaughter are lesser included offenses of first degree felony murder. Fuller v. United States, 132 U.S.App.D.C. 264, 407 F.2d 1199, 1229 (1968) (en banc).
. See United States v. Butler, 149 U.S.App. D.C. 300, 462 F.2d 1195 (1972), where the defendant was indicted for first degree felony murder for a homicide committed during a housebreaking, and for housebreaking. He was convicted of second degree murder (as a lesser included offense of felony murder) and housebreaking, and was given consecutive sentences for these two convictions, which we sustained. See also Jackson v. United States, 114 U.S.App.D.C. 181, 313 F.2d 572 (1962). See generally, Williams v. Oklahoma, 358 U.S. 576, 79 S.Ct. 421, 3 L.Ed.2d 516 (1959) (murder committed during kidnapping, and kidnapping, are separate offenses, and may be sentenced separately).
. In its petition for rehearing, the government also indicates that it has “been able to find no reported cases which have held that a merger occurs between the felony murder and its underlying felony.”
. See, e. g., Fuller v. United States, 132 U.S.App.D.C. 264, 407 F.2d 1199 (1968); Calloway v. United States, 130 U.S.App.D.C. 273, 399 F.2d 1006 (1968); Coleman v. United States, 111 U.S.App.D.C. 210, 295 F.2d 555 (1962); Carter v. United States, 96 U.S.App.D.C. 40, 223 F.2d 332 (1955); Wheeler v. United States, 82 U.S.App.D.C. 363, 165 F.2d 225 (1947).
. The D.O. felony murder conviction carries a minimum sentence that is five years greater than the minimum sentence on the federal premeditated murder conviction, see n. 27 supra. The federal assisting escape conviction, vacated by the court, carried a 20 month, minimum sentence. Thus, appellant’s sentence was increased by three years and four months.
. If the D.C.Code provision governing the burden of proof on insanity pleas could not apply to U.S.Code offenses, appellant was entitled to a retrial on the insanity phase of all of his convictions. See p. 1170-1171 infra.
. If appellant had been acquitted by reason of insanity on the federal murder charge, he probably would have been sent to Saint Elizabeths for treatment even if his D.C.Code armed robbery convictions were affirmed. See Kent v. United States, 119 U.S.App.D.C. 378, 343 F.2d 247, 250 (1965).
. See United States v. Williams, 150 U.S. App.D.C. 122, 463 F.2d 958 (1972).
. Although the question has never been considered, it seems clear that a defendant acquitted by reason of insanity on the underlying felony cannot also be convicted of felony murder since the underlying felony provides the mental state and intent otherwise needed for first degree murder. See p. 1168 supra.
. The statute governing the burden of proof was an amendment to the general D.C.Code provision on the insanity defense, which is applicable “in any criminal proceeding in the United States District Court for the District of Columbia or in the Superior Court of the District of Columbia . . . ” 24 D.C. Code § 301 (j) (1973) (emphasis supplied). See also notes 58, 65, 66 & 67 infra.
. “[S]eetion 301 (j) would have to be stretched far beyond the breaking point to be held applicable only to local offenses.”
. An under inclusive classification applies only to a part of a group who are similarly situated. See Rinaldi v. Yeager, 384 U.S. 305, 86 S.Ct. 1497, 16 L.Ed.2d 577 (1966) (unsuccessful appellants must reimburse state for transcripts, whereas successful appellants need not); Skinner v. Oklahoma, 316 U.S. 535, 62 S.Ct. 1110, 86 L.Ed. 1655 (1942) (sterilization for those who commit larceny, but not for those who commit embezzlement). See generally, Tussman & tenBroek, The Equal Protection of the Laws, 37 Calif.L.Rev. 341, 348-50 (1949); Note, Developments in the Law — Equal Protection, 82 Harv.L.Rev. 1065, 1084-86 (1969).
. An over inclusive classification applies not only to those similarly situated, but also to others who are not similarly situated. See Korematsu v. United States, 323 U.S. 214, 65 S.Ct. 193, 89 L.Ed. 194 (1944) (all persons of Japanese lineage confined due to fear of espionage or sabotage); Carrington v. Rash, *1171380 U.S. 89, 85 S.Ct. 775, 13 L.Ed.2d 675 (1965) (all members of armed forces prohibited from voting in Texas). See generally, Tussman & tenBroek, supra note 59 at 351-52; Note, supra note 59 at 1086-87.
. But see p. 1173-1174 infra.
. See pp. 1174-1180 infra.
. United States v. Reese, 92 U.S. 214, 221, 23 L.Ed. 563 (1875). See Kunz v. New York, 340 U.S. 290, 71 S.Ct. 312, 95 L.Ed. 280 (1951); Aptheker v. Secretary of State, 378 U.S. 500, 515, 84 S.Ct. 1659, 12 L.Ed.2d 992 (1964); United States v. Robel, 389 U.S. 258, 262, 88 S.Ct. 419, 19 L.Ed.2d 508 (1967).
The court might just as well have said that the D.C. statute does apply to federal offenses in this jurisdiction, and “put to one side” the question of whether the statute applies to federal offenses in other jurisdictions, and thereby frustrate appellant’s contention that the statute was under inclusive. While this suggestion seems ridiculous because the statute plainly does not apply to federal offenses in other jurisdictions, it is equally ridiculous to ignore its application to federal offenses in this jurisdiction, since the statute plainly does apply to them. See notes 58 & 59 supra, and 65 & 66 infra.
. Compare Skinner v. Oklahoma, 316 U.S. 535, 62 S.Ct. 1110, 86 L.Ed. 1655 (1942). The statute at issue there allowed sterilization of a felon who had committed two or more crimes “amounting to felonies involving moral turpitude.” Crimes of moral turpitude included, inter alia, larceny, but not embezzlement. The Court could have held that the state can sterilize those who repeatedly commit larcenies, compare Buck v. Bell, 274 U.S. 200, 47 S.Ct. 584, 71 L.Ed. 1000 (1927), and “put to one side” the question of whether the statute applied to embezzlers, since appellant, himself, had no embezzlement convictions. Instead, the Court recognized that the statute did not apply to embezzlers, and therefore it was a denial of equal protection because “[w]e have not the slightest basis for inferring that [the line between larceny and embezzlement] has any significance in eugenics, nor that the inheritability of criminal traits follows the neat legal distinctions which the law has marked between those two offenses.” 316 U.S. at 542, 62 S.Ct. at 1113.
. The amendment to the D.C.Code governing the burden of proof in insanity pleas does not indicate to which offenses it applies. The section that it amends, however, explicitly applies in “any proceeding” in the District Court as well as the Superior Court. I know of no principle of statutory construction that would allow us to limit the amendment to a different set of offenses than that covered by the section that it amends. Indeed, the court specifically relies on the fact that the amending portion of section 301 (j) is to be read as an integrated part of the whole section. Appellant claimed that the amending section — since it speaks in terms of “insanity” — required him to prove only his insanity, and not that the crime was a product thereof. See Durham v. United States, 94 U.S.App.D.C. 228, 214 F.2d 862 (1954). The court rejects this argument because the statute begins, as it did before the amendment, with “Insanity shall not be a defense,” and for that reason, the court concludes that the amendment applies to both elements of the insanity defense. (Court’s op. at 1152) (emphasis in original).
. See note 66 on page 1172.
*1172Moreover, Congress has made it clear that the whole of 24 D.C.Code § 301 is intended to apply to federal offenses tried in the District of Columbia. 24 D.C.Code § 301(h) (1973).
66. See H.R.Rep.No.91-907, 91st Cong., 2nd Sess. 73-75 (1970). The reason for the amendment was this court’s decision in Bolton v. Harris, 130 U.S.App.D.C. 1, 395 F.2d 642 (1968), which applies to those acquitted by reason of insanity on federal as well as local offenses in this jurisdiction. See pp. 1172-1174 infra.
. On federal offenses, the government would have to prove sanity beyond a reasonable doubt, whereas on local offenses, the defendant would have to prove insanity by a preponderance of the evidence. The government argued in its brief that “[s]uch a result cannot reasonably have been intended by Congress.” Compare United States v. Brown, 157 U.S.App.D.C. 311, 483 F.2d 1314 (1973) (federal bail statute applicable to D.C. offenses tried in federal district court).
. See 11 D.C.Code § 502(3) (1973).
. Indeed, a classification affecting the insanity defense may require a compelling legislative justification. The “convincing justification” test was enunciated in Thompson, where the interest at issue was bail pending appeal, which is clearly not of constitutional magnitude. See Harris v. United States, 404 U.S. 1232, 92 S.Ct. 10, 30 L.Ed.2d 25 (1971) (Douglas, Circuit Justice). The insanity defense, on the other hand, appears to be constitutionally required. See State v. Strasburg, 60 Wash. 106, 110 P. 1020 (1910); Sinclair v. State, 161 Miss. 142, 132 So. 581 (1931); cf. United States v. Brawner, 153 U.S.App.D.C. 1, 471 F.2d 969, 985-986 (1972). Discriminations with respect to constitutional rights require a “compelling interest.” Shapiro v. Thompson, 394 U.S. 618, 89 S.Ct. 1322, 22 L.Ed.2d 600 (1969) (right to travel).
. See H.R.Rep.No.91-907, supra note 66 at 73-74.
. We indicated in Bolton that an acquittal by reason of insanity is obviously an important consideration in a subsequent commitment hearing because it “may tend to show [that the defendant] meet[s] the requirements for commitment, namely, illness and dangerousness.” 395 F.2d at 651 (emphasis original) .
. H.R.Rep.No.91-907, supra note 66 at 74, quoted at court’s op., p. 1154 n. 9.
. This is so in two respects. First, even when the government was required to prove sanity beyond a reasonable doubt, there were very few successful insanity pleas in cases where the government objected to the plea. Data compiled by the United States Attorney’s Office in the District of Columbia indicate that in the seven years preceding the burden of proof amendment there were a total of 23 acquittals by reason of insanity in contested cases, or just over three a year. The data do not indicate which crimes were charged in these cases, hence it is not possible to determine whether these were “serious offenses.” Commentators, however, suggest that insanity acquittals are not won in serious cases, particularly murder trials. See Chernoff & Schaffer, Defending the Mentally Ill: Ethical Quicksand, 10 Amer.Crim.L.Rev. 505, 510-11 & n. 23 (1972).
Second, it appears that no one acquitted by reason of insanity has been released at a Bolton hearing unless Saint Elizabeths Hospital recommended release. On the other *1173hand, there have been patients denied release by the court despite a Hospital recommendation favoring- release. Cf. In United States v. Ecker, 156 U.S.App.D.C. 223, 479 F.2d 1206 (1973). In the past year, 57 people were eligible for Bolton hearings. Five people, on the recommendation of the Hospital, were released unconditionally: one had been charged with second degree burglary; one with robbery; one with assault with a deadly weapon; one with possessing and distributing a controlled substance; and one with failure to pay his bill at a rooming house. Another six people, also on the recommendation of the Hospital, were conditionally released: one had been charged with second degree burglary; one with sodomy; one with simple assault; one with assault with a deadly weapon; one with unauthorized use of a vehicle; and one with carrying a dangerous weapon. The other 46 were hospitalized, [These data and conclusions were provided by the staff at John Howard Pavillion, Saint Elizabeths Hospital. By citing them, I do not intend to indicate my approval of the administration of the insanity defense in this jurisdiction. See United States v. Brawner, 153 U.S.App.D.C. 1, 471 F.2d 969, 1010 (1972) (opinion of Bazelon, C. J.).]
. 24 D.C.Code § 301(d) (1973). As part of the Court Reform Act, Congress also amended section 301(d) to change the Bolton rule by placing the burden on a defendant acquitted by reason of insanity to prove by a preponderance of the evidence that he is no longer mentally ill or dangerous before he can be released.
. There is currently a bill, H.R. 12081, pending before the House Committee on the Judiciary, which would provide postacquittal commitment for those found not guilty by reason of insanity of any federal offense. The bill requires a hearing antecedent to such commitment, at which time the court must find that the person “by reason of mental disease or defect, is dangerous to himself or to the person or property of others,” § 4238(f). Commitment to a federal hospital would continue until the person may be “civilly committed pursuant to State law to a State facility.” § 4238(h). See note 77 infra. Thus, if a post-acquittal statute generally applicable to federal offenses is enacted, it appears likely that it will require a commitment hearing similar to the one required by Bolton.
Past efforts to enact similar legislation have been unsuccessful. See S. 3689 in 112 Cong. Rec. 18326 (Aug. 4, 1966) (for commitment after acquittal by reason of insanity of federal offense, government must prove “by a preponderance of the evidence, that the person is mentally ill, and that . . . his release would constitute a danger to himself or to others.”).
. Civil commitment procedures and standards vary greatly among the states. See S. Brakel & R. Rock, The Mentally Disabled and the Law 34-98 (1971).
. In most states, civil commitment is considered a “civil” proceeding, and therefore, the government is required to prove mental illness by a preponderance of the evidence. See Dershowitz, Preventive Confinement: A Suggested Framework for Constitutional Analysis, 51 Tex.L.Rev. 1277, 1295-1301 (1973). This court, however, has recently held that due process requires the government to prove mental illness and dangerousness beyond a reasonable doubt before a person can be civilly committed. In Re Ballay, 157 U.S.App.D.C. 59, 482 F.2d 648 (1973). See also In Re Pickles, 170 So.2d 603 (Ct.App.Fla.1965); Ex Parte Perry, 137 N.J.Eq. 161, 43 A.2d 885 (1945).

United States, 118 U.S.App.D.C. 168, 334 F. 2d 558, 565-566 (1964) (Congress may allow juries to prohibit capital punishment in murder cases in “the special maritime and territorial jurisdiction,” while not permitting them to do so in D.C.).

. The Supreme Court has been less vigilant in protecting the procedural rights of juveniles than adults. Compare McKeiver v. Pennsylvania, 403 U.S. 528, 91 S.Ct. 1976, 29 L.Ed. 2d 647 (1971) (jury trial not required in state juvenile delinquency adjudication), with Duncan v. Louisiana, 391 U.S. 145, 88 S.Ct. 1444, 20 L.Ed.2d 491 (1968) (jury trial required in state criminal proceeding).
. Even before Winship, some commentators had cast doubt upon the continuing vitality of Leland. See Report of the President’s D.C. Crime Commission 553 (1966).
. Obviously, a finding of insanity at the time the crime was committed says nothing about the perpetrator’s “propensity.”
. The court in this case acknowledges that “intent” comes within the Winship holding. Court’s op. at 1155.
. The Court’s reasons for constitutionalizing the “beyond a reasonable doubt” standard also demonstrate its intention to include sanity within the holding:
The accused during a criminal prosecution has at stake interests of immense importance, both because of the possibility that he may lose his liberty upon conviction and because of the certainty that he would be stigmatized by the eonviction. Accordingly, a society that values the good name and freedom of every individual should not condemn a man for commission of a crime when there is reasonable doubt about his guilt. 397 U.S. at 363-364, 90 S.Ct. at 1072. (emphasis supplied).
The rationale upon which the insanity defense rests is that a person who is unable to control himself at the time he commits an antisocial act should not be “condemned” or “stigmatized.” See Holloway v. United States, 80 U.S.App.D.C. 3, 148 F.2d 665 (1945); Durham v. United States, 94 U.S.App.D.C. 228, 214 F.2d 862 (1954); United States v. Brawner, 153 U.S.App.D.C. 1, 471 F.2d 969 (1972).
. See cases cited in court’s op. at 1151-1152.
. The court also claims that “[i]n United States v. Green, 150 U.S.App.D.C. 222, 463 F.2d 1313 (1972), in footnote 5, we affirmed what we held in Sill and Coleman, supra." (Court’s op. at 1152.) Green did nothing of the sort.. In footnote 5, the Green court said, “ [i] t is by no means clear that ‘sound memory and discretion’ is an element of first degree murder requiring affirmative proof.” The court continued, however, “[w]e mention this in passing, as we are not called upon in this case to decide whether the matter does require affirmative proof in all cases, since the proof was made here.” (Emphasis in original.)

But see id. at 1138 (Bazelon, C. J., dissenting in part) (jury should be instructed on nullification).
. Second degree murder and manslaughter are lesser included offenses of both felony murder and premeditated murder. See Fuller v. United States, 132 U.S.App.D.C. 264, 407 F.2d 1199 (1968).
. What Justices Taft and Frankfurter have said in other contexts is appropriate here: “We would have to be [a] ‘blind’ Court . . . not [to] see what ‘[a]ll others can see and understand.’ ” United States v. Rumely, 345 U.S. 41, 44, 73 S.Ct. 543, 545, 97 L.Ed. 770 (1953), quoting Child Labor Tax Case, 259 U.S. 20, 37, 42 S.Ct. 449, 66 L.Ed. 817 (1922).
. See cases cited at court’s op. 1157. Most of these cases hold that it is not error for the trial judge to refuse a defense request for bifurcation.
. The Davis Court explained that the defendant was required to introduce some evidence of insanity because of the “presumption which the law, justified by the general experience of mankind as well as by considerations of public safety, indulges in favor of sanity.” 160 U.S. at 486, 16 S.Ct. *1179at 357. Nonetheless, it concluded, “a verdict of guilty [cannot] be properly returned, if the jury entertain a reasonable doubt as to the existence of a fact which is essential to guilt, namely, the capacity in law of the accused to commit th[e] crime.” Id. at 488, 16 S.Ct. at 358.
