Appellant, Thomas Robertson, who was found mentally competent to stand trial, expressly refused to invoke the defense of insanity. He was convicted by a jury of second-degree murder, assault with intent to kill while armed and carrying a pistol without a license (22 D.C.Code §§ 2403, 3202, 3204), for which he received concurrent sentences of ten years to life, two to fifteen years, and one year respectively.
*1150After the jury found that Robertson committed the acts charged, the court held a hearing to consider whether it should raise the insanity defense sua sponte and submit the issue to the jury in a bifurcated proceeding. Robertson opposed imposition of the insanity defense. In accordance with that opposition, he called no witnesses and did not cross-examine the witnesses who testified for the prosecution. The hearing culminated in the court’s determination not to raise the insanity defense. Robertson now contends in this appeal that this decision was erroneous.1
For the reasons set forth herein, we remand the record to the District Court.
I.
A. Events of August 20, 1971
The facts in this case are not in dispute. Appellant Robertson suffered a bloody wound over his forehead during a fist fight outside the Academy pool hall sometime between 4:30 and 5:00 on the afternoon of August 20, 1971. The reason for the fight and the identity of Robertson’s opponent were not disclosed at trial. After the fight was stopped by on-lookers, Robertson left in his car. He returned approximately one-half hour later and momentarily appeared at the entrance of the Academy pool hall. He then crossed the street to another pool hall before once again returning to the Academy. Passing by a table where two men were playing pool, he suddenly turned, whipped out a gun, and shot one of the men at the table, injuring him in the shoulder. Robertsoh then ran out of the pool hall, jumped into his car, and drove the wrong way down a one-way street.2
About fifteen minutes later, Robertson was seen in the midst of rush hour traffic, speeding and careening down the wrong lane of busy U Street in the face of on-coming traffic. He collided with a parked car, swerved over into the opposite lane and, after striking still other ears, came to a stop. Robertson then got out of his car, drew a gun, and stopped to talk briefly with the occupants of a car directly behind him, all of whom were Black.3 Robert Aleshire, whose parked car Robertson had struck initially, was inspecting the damage when Robertson strode across the street towards him. Aleshire, who was White, leaned against the car as Robertson approached. When he reached Aleshire, Robertson shot him at point blank range, once in the shoulder and twice in the chest and abdomen. As one witness described it, “. . . [the] surprising thing [was] that he [Aleshire] made no motion at all. As he turned around, Mr. Robertson was there and he [Robertson] just lifted the gun and shot him.” 4
After shooting Aleshire, Robertson raced down the middle of the street, brandishing his pistol and cursing the “white sons-of-bitches.” 5 Seeing a police officer, he shouted, “You are doing it; why can’t I?”6 “Yes, I shot the white honkey son-of-a-bitch. What are you all going to do about it?” 7 A witness who was taken to the police station with Robertson testified that he continued to make such statements throughout the trip, saying, for example: “[a] 11 of the white sons of bitches need to be killed or shot, I had did [sic] my part *1151and I can’t do anymore. . . . All the sons of bitches should be shot, . and that is the problem there isn’t enough of us doing this sort of thing.” 8
B. Pre-trial Mental Examinations and Status Hearings on the Insanity Defense
At a preliminary hearing on August 30, 1971, the Superior Court of the District of Columbia ordered Robertson committed to Saint Elizabeths Hospital pursuant to 24 D.C.Code § 301(a) for a psychiatric examination to determine competency and mental status at the time of the crime. Addressing the court, Robertson stated:
“. . . I’m not going to get justice, I realize this perfectly. See, I’m one who is well versed in whiteness. You won’t get your white vengeance. ... I have never been guilty of nothing [sic] but being born black in a white America — racist white America. . . . But, I am not going to let you think that I do not realize who I am and who you are. You are the beast and I am a man. You say I killed a man. I have killed no man in my whole life.”
The court responded, “I will sign the order, gentlemen. We’ll make it forthwith. I think he should be at the hospital and not in jail.” 9
While awaiting admission to Saint Elizabeths, Robertson was arraigned before the District Court, which on September 20 entered a new order for commitment to Saint Elizabeths. Shortly thereafter Robertson was admitted for examination. Two letters to the court from Saint Elizabeths Hospital, dated October 21 and November 9, 1971, reported Robertson competent and not suffering from a mental disease or defect. On September 28, the court granted the government’s motion for examination of Robertson by Dr. John Cavanagh, a private psychiatric practitioner. Shortly thereafter the court granted Robertson’s motions for an examination by Dr. Alyce Gullattee, a psychiatrist, and by Dr. Ronald Dockett, a psychologist, both engaged in private practice.
After all pre-trial mental examinations had been completed, Robertson notified the court at a March 24 status hearing held for purposes of scheduling the trial that, against advice of his counsel, he would not rely on the defense of insanity. Because all of the psychiatric evaluations found Robertson competent to stand trial, his counsel said that they would abide by his decision. The government, however, cited the “bizarre facts of this case” and called the court’s attention to the fact that some of the experts’ reports contained information supporting an insanity defense.10
When the court asked Robertson his reasons for refusing to rely on the insanity defense, he declined to respond, but wrote a note that read: “I refuse to communicate in your language for the duration of my last six hours of incar*1152ceration. By my left side.” After reading the note, the court agreed with the government that a pre-trial hearing was necessary to decide whether the. insanity defense should be raised sua sponte over Robertson’s objection.11
At the pre-trial insanity defense hearing held April 10, Robertson’s counsel informed the court that they had discussed with him the “substantial” merits of an insanity defense, but that he still declined to raise it.12 Therefore, Robertson’s counsel argued, inter alia, that imposition of the insanity defense would violate Robertson’s Sixth Amendment right to effective assistance of counsel, would improperly interfere with the conduct of the defense, and would violate his right to due process since D.C.Code § 24-301 (j), enacted in 1970, transfers the burden of proof of insanity onto the defendant.13
The government urged the court to hear and determine the merits first, and then to turn to the insanity issue in a bifurcated proceeding. The court thereupon certified Robertson competent to stand trial and set a trial on the merits. It also announced that if the jury found against Robertson, the court would determine whether a sufficient basis existed for imposing the insanity defense in a bifurcated trial.14
C. Trial on the Merits
On Robertson’s motion at the close of the government’s case, the court directed a verdict of acquittal on the first degree murder charge and submitted to the jury the lesser included offense of second degree murder. The court characterized the circumstances surrounding the death of Aleshire as “uncontradicted evidence that this was an impulsive frenzied act.” 15 The court explained:
“We have here testimony in this case what this man’s state of mind was, what the situation was at the poolroom, outside the poolroom, inside the poolroom, . . . the Hart shooting [in the poolroom] happened so quickly and under such circumstances there can be no reasonable inference that his state of mind when he left the poolroom was any different from his state of mind when he arrived at 13th and U.” 16
During the last two days of the trial, Robertson had to be carried into the courtroom; his posture was “limp” and his head often rested on the table as if he were in a stupor17 The trial court viewed Robertson’s conduct as intentional posturing: “I am convinced that he is feigning. I am convinced that it is an act.”18 At a subsequent hearing on whether the insanity defense should be raised sua sponte, witnesses called by the government supported the trial court’s observations. The Superintendent of the District of Columbia Jail and a United States Marshal reported that, when observed outside the courtroom, Robertson acted “normally.” 19 Dr. Albert E. Marland, a psychiatric consultant at Saint Elizabeths Hospital, and Dr. John Cavanagh, a private psychiatrist appointed at the government’s request,20 testified that Robertson’s conduct did not indicate a mental disorder but rather conscious malingering.21
*1153D. Consideration of the Insanity Defense
After the jury found Robertson had committed the acts in question, the court held a hearing on whether the insanity defense should be raised sua sponte. The court had before it the differing opinions set forth in the written reports of the experts concerning Robertson’s mental state at the time of the crimes. In his written report filed with the court, Dr. Marland described Robertson’s history as one of “aggressive nonconformity, [and] assaultive activity.” According to Dr. Marland, Robertson reportedly spent much of his time in maximum security and solitary confinement in prisons in Virginia, Ohio, Illinois, Kentucky, Georgia, and Washington, D. C. He was raised in Washington, “mostly in precinct two which he admits is a tough area.” Dr. Marland found that although Robertson was polite, his remarks were heavily overladen with “anti-racial philosophy with a lot of double talk.” Dr. Marland concluded his report with the diagnosis of “anti-social personality, severe” on the basis of Robertson’s past conduct and racial philosophy:
“I believe that his talk about human-isn is not delusional, but that he is malingering with his double talk. He is impulsive, but not delusional. . He has a long history of aggressive antisocial behavior with rebellion against authority, but although today he denies racism verbally, [sic] Today there is no question of his identity with racial rebellion. He is superior intellectually with an arrogant expression of superiority to most people. He has always been hyperki-netic, he applies the word to himself. His attitude to authority ... is one of rebellion and aggression.
Dr. Marland testified at the hearing that Robertson was not mentally ill but rather a “sociopathic personality.” Robertson did not suffer from a “neurosis” or “psychosis” but instead was diagnosed as “anti-social personality —severe type,” defined as “a condition in which a person does not relate well with others.” “It is not a mental disorder. It is merely a disturbance.”22 Marland characterized Robertson’s conduct after the shooting of Aleshire as consistent with “exhibitionistic tendencies,” i. e., those of a “show-off.” He asserted, “I knew that he was an exhibitionist before I ever examined him.”23
The written report of Dr. John Cavanagh, the other prosecution expert, described his version of the shooting. According to the report, Robertson stated (Dr. Cavanagh’s comments are in parentheses) :
“. . . [a]ll my education which was aimed at making me white was in the District of Columbia. (Are you white?) I am what I am — The man I allegedly shot was a beast — neither *1154white nor black. The worst kind of beast. I was trying, but never succeeded. (They tried to make him white, i. e., an inferior being. The man I allegedly shot was a beast, i. e., not a human being.)”
Robertson, a student at Federal City College, revealed to Dr. Cavanagh that he was writing an essay entitled “In Search of an Identity in Racist White America.” According to Dr. Cavanagh’s report, Robertson explained his “search” this way (Dr. Cavanagh’s comments are in parentheses):
“The negro has a limited degree of manhood. He can be one-third man. A Black Man is unlimited. I am a man. I am the man you think you are. This is a trial for my extinction. They don’t want too many me’s running around. (He gesticulates constantly. A Black Man has unlimited power and is not restricted by law. They have arrested me and by this trial seek my elimination. The powers that be want to eliminate people like “me”.)
Murder is no different that [sic] war. (In war one is allowed to kill.)
If a black man kills a white man, it is not a crime. It is getting the oppression off his neck.
If a black man kills a black man, it is murder. I was under a lot of pressure on that day. The tension was due to the circumstances of my birth. People talk about me wherever I am. I am the topic of conversation. (More grandiosity, more need to be respected and looked up to. More hostility against the white man, “circumstances of my birth.”)”
Robertson had explicitly asked Cava-nagh to find him competent to stand trial. Cavanagh interpreted Robertson’s remarks to mean that a finding of incompetency would indicate a defect in his character (and presumably impeach his philosophy). In reviewing the content of the interview, Dr. Cavanagh’s report concluded: “Mr. Robertson at first glance appears to be psychotic, but on better acquaintance, it becomes clear that what appears to be psychotic mental content is more likely an expression of a cultural [sic] adopted language.” [Emphasis added.] The doctor diagnosed Robertson as “antisocial personality,” which he described as behavior “grossly selfish, callous, irresponsible, impulsive, and unable to feel guilt or to learn from experience and punishment.”
In his testimony at the hearing, Dr. Cavanagh indicated that Robertson could distinguish “right from wrong” and could exercise freedom of choice: “[There is] no evidence that would cause me to believe that he was compelled to do anything on that date. He knew it would have been wrong to kill a black man. He wasn’t sure it was wrong to kill a white man. But he knew he was breaking the law. . . . ”24 Dr. Cavanagh concluded that Robertson was not schizophrenic at the time of the Aleshire shooting, an opinion contrary to that expressed in the written report of Dr. Gullattee discussed below.
Because Robertson opposed raising the insanity defense, neither Dr. Cavanagh nor Dr. Marland was cross-examined. The court was not requested to appoint independent counsel as amicus and did not do so on its own initiative. Furthermore, the experts who had been appointed at the request of Robertson were not called to testify. One of these experts, Dr. Alyce Gullattee, a psychiatrist, in her written report found Robertson to be competent but “suffering from a mental condition and [his] criminal offenses were a product of that mental condition diagnosed as schizophrenia, schizo-affected type.” She reported that Robertson had a history of “juvenile aberrant behavior,” had been sentenced under the Youth Corrections Act for a narcotics conviction, and had a prior history of treatment for “emotional problems" as an adult. On examination, Dr. Gullattee found Robertson’s *1155emotions frequently inappropriate. He often answered questions not asked of him, behavior that he attributed to extra-sensory perception. Extremely articulate, he seemed to be obsessed with concerns about “his sexual identity and Black ideology.” Robertson described himself as a “victim” with “multiple threats to his existence” including “attempts to poison him.” Because of these fears, he was “always sensitive to white oppression which interfres [sic] with the economics of Blacks.”
The other defendant expert, Dr. Ronald Dockett, a clinical psychologist, found significant psychological impairment. His report stated that, although Robertson “overtly presents the impression of a well-oriented person,” on further examination “delusional material becomes apparent.” These delusions include “delusions of persecution and influence” as well as the belief that a “computor [sic] is controlling his life.” Psychological examination showed Robertson’s thinking (cognitive) processes intact. They also showed, however, considerable “sexual confusion,” generating rage that could overwhelm Robertson’s “splintered” ego and result in aggressive behavior. Dr. Dockett described the identity problems of Robertson as “confused, irrational and basically pathological,” which were projected on Whites. These emotional forces created a breakdown in reality testing, contributing to impulsive and destructive behavior.
The government informed the courts that the purpose of the hearing testimony elicited from Drs. Marland and Cava-nagh was to counter the findings of Dr. Gullattee. The court acknowledged its awareness of this conflict. Apparently relying on the fact that of all the examining experts only Dr. Gullattee was Black, the court, which was also Black, observed at the conclusion of the hearing:
“Dr. Gallotti [sic] is talking the same language as this defendant; he [sic] is talking it as a psychiatrist, who knows this defendant in a way that Dr. Marland and the other doctor will never know him.
It is a world that they don’t understand. It is a world that they are not a part of. It is a world that they only relate to through books.
And that is why Dr. Gallotti’s [sic] interpretation and her conclusion that he is mentally ill is only in her attempt to fit his situation and her understanding of it into the lexicon and into the vernacular vocabulary of psychiatric medicine, as we are forced to use it in a court of law. That is what it is all about.” 25
After the government presented its experts, Robertson’s request to testify was allowed over the objections of his counsel. Robertson said that his name was not “Thomas L. Robertson” but rather “Thomas X. King.” He told the court that the murder of Aleshire was a “double murder” for on that day Robertson, as well as Aleshire, had died, and King was born: “It was life being given as to life being taken.” In Robertson’s view the trial was a charade: “[W]hat is spoken doesn’t matter. It is what is unspoken that counts. What is on the line is nothing. What is between the lines is everything.”26 In response to questions by the government, Robertson stated that he had been “in a prison all my life” and declared that he was “paranoid as the term is understood,” and “begging for help.” 27
At the conclusion of this hearing, the trial judge also commented:
“He [appellant] knows that I know that he is not crazy. He knows that I know that he is not crazy.
And all this byplay about his name and all that kind of business — I understand Robertson. And he knows *1156that I understand him — because I have dealt with Robertsons over the years, little Robertsons and big Rob-ertsons.
And I know everything about the condition of life that made him exactly what he is and what he is going to be. And what he is going to be. He is not alone.
The public at large will never understand. But there are people who do. Now, there is no basis for me to raise the insanity plea in this case, the insanity defense.
Do you see what he is saying to his lawyers and what he is saying to the community? T won’t cop out.’
‘I won’t cop out.’
T won’t cop out.’
No. I will not raise the insanity defense.”28 (Emphasis supplied.)
Appellant was remanded to custody to await sentencing.
E. Sentencing Hearing
Thereafter, and prior to the sentencing hearing, Robertson was placed in the jail hospital for bizarre behavior and examined by Dr. Alec J. Whyte, a consultant to the Forensic Psychiatric Office for the District of Columbia.
Apparently because he had reported Robertson incompetent to stand sentencing on the basis of his examination and had referred Robertson to Saint Eliza-beths for further examination, Dr. Whyte was called by the defense at the sentencing hearing. He testified that his impression, one not confirmed by full diagnosis, was that Robertson was in an “acute psychotic decompensation”:
“Well, I found him . . . in a bed without clothes on, rocking back and forth constantly. He responded to my questions in a completely unintelligible way, usually with a rather bizarre laughter. . . . But none of his responses were in any way appropriate, nor were the . . . emotional responses to the questions what you would expect to the seriousness of the interview.” 29
On the basis of a letter to the court from Saint Elizabeths Hospital reporting that Robertson was competent and that the original hospital diagonsis of “anti-social personality” was confirmed,30 the court concluded that Robertson was competent and could be sentenced. In addressing the court prior to sentencing, Robertson said of the court’s comments concerning Dr. Gullattee’s report:
“You [the court] made a statement once before that I was [in] a world— that none of them understood and I have thought about that a great deal, you know. And that was the trest [sic] statement that I ever heard in this courtroom, but I didn’t understand it, as you said.”31
The government argued for a sentence commensurate with the high degree of dangerousness of appellant. In response the court stated,
“[Robertson] is dangerous in our view because you know that the system doesn’t understand him. And you know the system can’t control him. That is why he is dangerous. They can’t control him, except by the use of force. That is why he is dangerous.”32
Defense counsel argued that Robertson required help. The court responded,
“Don’t you understand Mr. Robertson doesn’t want your help. He doesn’t need it because the only help that can be offered is help that he completely *1157rejected. That is what he is telling you. ... He will make it on his terms in his good time. That is what he has said. That is what his life has said. ... He has the capacity for insight. And he has a sensitivity, too, the likes of which few defendants have about his predicament, not just his personal predicament, but his predicament generally.” 33
II
Counsel for Robertson in this court argues that the overriding factual issue in this case- remains unanswered:
“What went on in the mind of Thomas L. Robertson [appellant] on August 21, 1971, that caused him to enter a poolroom and shoot a man in the shoulder and minutes later approach a total stranger in the middle of the street and fire fatal shots into his chest and abdomen from point blank range ?” 34 Under our system of jurisprudence this kind of question is traditionally left for jury resolution under the rubric of the insanity defense. But here the defendant refused to interpose that defense.
In Whalem v. United States, this court sitting en banc held that
when there is sufficient question as to a defendant’s mental responsibility at the time of the crime, that issue must become part of the case. . . . So, our query is whether in this case there was a combination of factors which required the trial judge to inject the insanity issue for, if such factors existed, his failure to do so is an abuse of discretion and constitutes error.35
The rule in Whalem rests on the belief that “[o]ur collective conscience does not allow punishment where it cannot impose blame.”36 In accordance with that philosophy, the District Court in the present case properly observed that “[n]o insane person — no person with a mental disease or a mental defect— should ever be convicted of a crime in this jurisdiction.” 37
This court has accepted the Whalem formulation by repeatedly acknowledging the trial court’s authority to impose an insanity defense. While we have acknowledged our power to review the trial court’s exercise of discretion, in cases subsequent to Whalem we have never overturned a trial court’s determination in the matter of raising the defense sua sponte?38 nor have we articulated standards to govern that determination. In Whalem the court added in a footnote, “No rigid standard exists to control the District Court in deciding whether it should require the insanity issue to be submitted. As a matter *1158within the sound discretion of the District Court, this question must be resolved on a case by case basis.” 39 In Cross v. United States we rejected the government’s suggestion that the trial court’s determination may be disturbed only if the evidence would require a directed verdict of not guilty by reason of insanity.40 Nor did this court accept the suggestion that “[t]he ‘substantial doubt’ test of competency to be tried set out in Hansford v. United States, 124 U.S.App.D.C. 387, 365 F.2d 920, . . . [be] transferred to the issue of responsibility [under Whalem].” 41
In this case there is much in the record suggesting that Robertson may have been unable to control himself at the time he committed the acts in question. The acts themselves are sufficiently bizarre to be “suggestive on [their] face of mental illness” ;42 indeed, in reducing the charge from first degree murder to second degree murder, the court characterized these acts as “impulsive and frenzied.”
Robertson opposed the insanity defense largely, according to some evidence, because of his belief that that defense would impugn the credibility of his racial and political views.43 However, defense counsel apparently thought it appropriate to raise the insanity defense. He refused to do so solely because Robertson forbade it. Even the government thought that the evidence of mental illness was sufficiently great that there should be careful consideration given to the “interposing of the insanity defense out of an abundance of caution. . . . ”44 Most importantly, perhaps two of the four experts who examined Robertson prior to the hearing which Judge Robinson held in order to determine whether an insanity defense should be interposed, along with Dr. Whyte in his subsequent report, expressed views which in large part were highly supportive of an insanity plea. Additionally, Robertson’s behavior at trial raises troubling questions about his mental condition.-
Under the circumstances, it seems clear that Judge Robinson acted fully and most commendably in accord with the spirit of Whalem in ordering an insanity hearing. However, once having embarked upon a W/iaiem-type hearing, the trial judge should have insured that he hear evidence supporting as well as opposing the imposition of an insanity defense. The appointment of amicus counsel would appear to be one way of insuring the presentation of such evidence.45 Drs. Marland and Cavanagh should have been questioned closely as to *1159any problems, defects or incompleteness there may have been either in their written reports or in their oral testimony. The basis for their conclusions as to Robertson’s sanity should have been probed. Moreover, one or more of Drs. Gullattee, Docket and Whyte, and/or one or more of the staff doctors at Saint Elizabeths should have testified in sufficient number and in sufficient depth to present to the court views different than those expressed by Drs. Marland and Cavanagh. To hear only from these latter two doctors, in repetition of their earlier expressed written views, was in effect to render repetitious and nugatory a Whalem-type hearing. We think that Whdlem dictates that a trial court’s final assessment of conflicting expert opinion and its decision whether or not to raise the insanity defense may not rest solely on the unchallenged testimony of the government experts in the absence of testimony of the other experts. This dictate is especially compelling in this case where Dr. Gullattee, the expert who found the defendant mentally ill, had been characterized by the District Court as one who “knows this defendant in a way that [the government’s psychiatrists] will never know him.” 46
The failure in this case to hold a full hearing and the decision to entertain only the testimony of Drs. Marland and Cavanagh is aggravated by the concluso-ry type of reports offered by these two doctors. Dr. Marland testified for the government that Robertson was not mentally ill but was an “anti-social personality, severe.” Dr. Cavanagh reported that Robertson “at first glance appears to be psychotic, but on better acquaintance it becomes clear that what appears to be psychotic mental content is more likely an expression of a cultural [sic] adopted language.” 47 What factors led the two doctors to their respective conclusions? This is precisely the kind of question which requires probing by cross-examination. .
In the end, any trial judge faced with the problem before the court below will of necessity be required to make an appraisal of the defendant. We note, as Judge Wilkey writes in his dissent, that we are “three white appellate judges who have never laid eyes on the defendant or heard a witness in the case.” We note also that the trial judge, a Black, appropriately took into account, as a matter of common sense and his own experience and background, his own “feel” of the defendant. Trial judges instruct jurors as a matter of routine that they should carefully weigh all opinion evidence and should not leave their common sense behind them when they enter the jury room to deliberate and to decide. A trial judge exercising his discretion in a Whalern setting should of course do no less. But before a District Court relies upon its own understanding of the defendant, and indicates that in the court’s view the community lacks understanding of the defendant, the District Court must set forth the reasons upon which it *1160rests such conclusions,48 must articulate the basis for its common sense reasoning, and must hear and consider the differing views of the experts in a case such as this one, in which those differences go straight to the heart of the ultimate issue.
The common sense conclusion reached by the trial judge in this case makes especially compelling the need for the full consideration of the testimony of opposing experts. The trial court’s decision not to impose the insanity defense rested, in large part, on Robertson’s rejection of the defense as a “cop out.” Plainly, since it is a defendant’s rejection which triggers a Whalem inquiry, that rejection should not have been controlling. Robertson’s rejection and his reasons for it should have been weighed with evidence derived from a full presentation of testimony relevant to the issue of criminal responsibility.
III
A few further words about Whale to would appear appropriate. The rule in that case may itself fly in the face of the views of the draftsmen of the Model Penal Code49 who, though finding it “desirable” to accord a trial judge the power sua sponte to raise the insanity defense in a “proper ease” omitted such a provision from the Code as “too great an interference with the conduct of the defense.” 50 On the other hand, the use of a bifurcated procedure, pursuant to which the insanity issue remains out of the case until after trial on all of the other merits has been concluded, would seemingly make it possible for consideration to be given to the interposition of an insanity defense without “too great an interference with the conduct of the defense.” 51 But be that as it may, we think that Whalem itself dictates certain substantive norms and *1161procedural devices by which the duty it imposes must be exercised. Whalem speaks in terms of a “sufficient question” as to the defendant’s “mental responsibility” as the criterion for the court’s imposing the insanity defense sua sponte and submitting it to the jury. Accordingly, we think a viable construction of the rule in Whalem requires that when a “sufficient question” is potentially posed by differing views of experts, the trial judge must conduct on the record a thorough exploration of the same and in addition set forth in reasonable detail the reasons for his own ultimate determination. In reaching that determination he is of course not bound to adopt in whole or in part the views of any expert. But no appellate court in our position can sensibly decide whether the trial judge has explored and exercised his discretion as required by Whal-em unless the trial judge completes the exploration on the record and thereafter records in sufficient detail the reasons for his own expression of opinion.
The record is therefore remanded for supplementation in accordance with this opinion.
Separate Statement of Chief Judge BAZELON:
I did not join this court’s decision in Whalem,1 nor have I been a member of any division of this court in eases which applied Whalem2 The issues in Whalem have been and continue to be deeply troubling for me. They are painfully posed in the present case by a defendant who claims that the insanity defense denigrates and denies his racial and social protest.
At least until Whalem may be reconsidered by the court en banc, its flexibility allows confrontation with the ethical conflict between the individual’s right to recognition of his protest and society’s right to deny such recognition.
. Appellant also contends that his conviction for assault with intent to kill should be reversed on the ground that there was insufficient evidence to sustain the jury verdict on the element of intent. Robertson shot the victim at a distance of six feet and injured his shoulder. Such evidence was sufficient to support the jury verdict. See United States v. Bridges, 139 U.S.App.D.C. 259, 432 F.2d 692 (1970).

Defense counsel stated that appellant’s family had informed him that:
since about a six month period of this year they have noticed the defendant had severe mental problems and manifested by fits of anger and they have tried to have him committed but efforts have failed. The brother went to Saint, Elizabeth’s [sic] and inquired as to how he would get his brother in and apparently they were unsuccessful in getting him committed.

Dr. Marland did not define tlie terms “psychosis,” “neurosis,” or “mental illness.” The use of such conclusory medical labels without explanation contributes nothing to the determination of the legal issue of defendant’s criminal responsibility. “[F]or purposes of the insanity defense, ‘mental illness’ is a legal term of art. A criminal defendant’s responsibility cannot turn on the label attached to his condtion.” United States v. Alexander & Murdock, 152 U.S.App.D.C. 371, 471 F.2d 923, 958 (1972) (Bazelon, C. J., dissenting) ; see also United States v. Brawner, 153 U.S.App.D.C. 1, 42, 471 F.2d 969, 1010 (1972) (Bazelon, C. J., concurring in part and dissenting in part).

The Saint Elizabeths staff report which accompanied Dr. Mar-land’s report noted that Robertson’s mother reported an incident in which he “disrobed and for the better part of the night terrorized [the family], but did not hurt them, [and] made numerous various statements of his manhood.” The staff also reported that while at Saint Elizabeths Robertson quoted from the “literature of the black culture.” The staff interpreted these quotations as a means to “reinforce his manhood.” Robertson informed the staff that the shooting in the pool hall was not intended to kill the victim. It was simply aimed at “put [ting] an underling in his place.” The killing of Aleshire, he claimed, was not murder since “white [s] are [not] human.”

. The government argued that the Saint Elizabeths report was more thorough than Dr. Whyte’s findings since the Hospital had greater opportunity for evaluation. Defense counsel, however, noted that the Hospital report had repeated verbatim the diagnosis contained in the earlier report on sanity and competency. Sen.Tr. at 12, 15.

. Cross v. United States, 122 U.S.App.D.C. 380, 354 F.2d 512 (1965) was remanded for reconsideration in light of Whalem, since the trial court had indicated its belief that it lacked power to impose the defense over the objections of the defendant. Otherwise, we have affirmed refusal to raise the defense. E. g., United States v. Simms, 150 U.S.App. D.C. 182, 463 F.2d 1273 (1972) ; United States v. Bradley, 149 U.S.App.D.C. 405, 463 F. 2d 808 (1972) ; Trest v. United States, 122 U.S.App.D.C. 11, 350 F.2d 794 (1965), cert. denied, 382 U.S. 1018, 86 S.Ct. 634, 15 L.Ed. 2d 532 (1966).

. It would appear from the medical report filed by Saint Elizabeths that Robertson derived his thinking from Franz Fanón, a psychiatrist who wrote about the problems of Blacks in colonial Africa, and who argued that violence was a means needed to free Blacks from White oppression. See generally F. Fanón, The Wretched of the Earth (1968) ; F. Fanón, Black Skin, White Masks (1967). See also Adams, The Social Psychiatry of Franz Fanón, 127 Amer.J. of Psychiat. 809 (1970).
One of the cruelest ironies of this tragic case is that the victim, Robert Aleshire, whom Robertson viewed as a “white oppressor”, was committed to renewal of the central city and dedicated to social justice. In a eulogy delivered by Philip Rutledge, then director of Washington’s Human Resources Department, Aleshire was described as a man who “helped to map a strategy for the improvement and conservation of [this city’s] human resources — a strategy that through renewing human beings [one could] prevent tragedies such as the one which stalked him at 13th and U.” Editorial, I Never Thought of Violence, Washington Post, Sept. 3, 1971, p. 24 at col. 1.

. In a situation in which defense counsel is not permitted by his own client, the defendant, to call, examine and cross-examine witnesses, the appointment and participation of amicus counsel may well be the only way to *1159elicit such evidence. As to the possible duality of roles which the trial judge might play, there are many dangers. Cf. the probing analysis of Chief Judge Aldrich in Figueroa Ruiz v. Delgado, 359 F.2d 718 (1st Cir. 1966).
. I.H.Tr. at 66. The court also noted that Dr. Gullattee undertook the difficult task of trying “to fit [Robertson’s] situation and her understanding of it into the lexicon and into the vernacular vocabulary of psychiatric medicine, as we are forced to use it in a court of law.” Considerable dispute has arisen over the question of cultural and racial bias in psychiatric practice. See Sab-shin, Diesenhaus, & Wilkerson, Dimension of Institutional Racism in Psychiatry, 127 Amer.J.Psychiat. 787, 788 (1970) (“the black American has had to face the charges of white racists that he is supposed to be innately lazy, unhealthy, unintelligent, and criminal. White American psychiatry has its equivalent racist stereotypes about the black psychiatric patient: hostile and not motivated for treatment, having primitive character structure, not psychologically minded, and impulse ridden”) (emphasis in original). See also H. Greer & P. Cobbs, Black Rage (1968) (different norms govern evaluation of symptoms such as “paranoia” and “depression” depending on race of patient).

. The court did not attempt to itemize the factors on which it relied in claiming to “understand” Robertson. There were, however, records before the court indicating that appellant was raised by his mother in one of Washington’s “tougher” areas. His criminal record is extensive. In 1964 he was sentenced under the Youth Corrections Act for a drug-related offense, and his record indicates he was a disciplinary problem, that he was “belligerent” and a “racial agitator.” He assaulted two caseworkers, then stabbed a fellow inmate during a fight. For his own protection he was transferred to another federal prison.
. Relying on the ALI Model Penal Code position in his dissent, our dissenting brother finds no authority in this circuit to support the interposition of an insanity defense against appellant’s will. Dissent of Judge Wilkey, page 1167. We think Whalem, is clear authority. There we said that “in the pursuit of justice, a trial judge must have the discretion to impose an unwanted [insanity] defense on a defendant . . . ” Whalem v. United States, supra, 346 F.2d at 818-819.
. Model Penal Code § 403 (Comment, Tent. Dr. No. 4, 1955) (“While it was considered desirable to give the trial judge the power to raise the defense of irresponsibility in a proper case, where a defendant refuses to permit his counsel to do so, such a provision was finally omitted as being too great an interference with the conduct of the defense.”). Other commentators have reasoned similarly. See, e. g., A Goldstein, The Insanity Defense 188 (1967) ; J. Goldstein, The Brawner Rule — Why? or No More None-sense on Non Sense in the Criminal Law, Please!, 1973 Wash.U.L.Q. 126. But of. ABA Standards Relating to the Function of the Trial Judge 1.1(a) (Tent.Draft, June, 1972) :
The trial judge has the responsibility for safeguarding both the rights of the accused and the interests of the public in the administration of criminal justice. The adversary nature of the proceedings does not relieve the trial judge of the obligation of raising on his own initiative at all appropriate times and in an appropriate manner, matters which may significantly promote a just determination of the trial. The only purpose of a criminal trial is to determine whether the prosecution has established the guilt of the accused as required by law, and the trial judge should not allow the proceedings to be used for any other purpose.
. This court has repeatedly recognized the value of the bifurcated procedure. See, e. g., United States v. Green, 150 U.S.App. 222, 223-224, 463 F.2d 1313, 1314-1315 (1972) ; Holmes v. United States, 124 U.S.App.D.C. 152, 363 F.2d 281 (1966).
