     Before:  Wald, Williams and Tatel, Circuit Judges.

     Opinion for the Court filed by Circuit Judge Wald.

     Wald, Circuit Judge:  On December 6, 1995, a jury convict-
ed Larry Burch ("Burch") of possession with intent to distrib-
ute more than 50 grams of cocaine base in violation of 21 
U.S.C. ss 841(a)(1) and 841(b)(1)(A)(iii) (1994), while acquit-
ting him on a charge of conspiracy to distribute and to 
possess with intent to distribute cocaine base in violation of 21 
U.S.C. s 846 (1994).  While the defendant's direct appeal was 
pending, he petitioned for a writ of habeas corpus under 28 
U.S.C. s 2255 (1996), alleging both ineffective assistance of 
counsel and prosecutorial misconduct.  The district court 
judge who presided over the defendant's trial denied the 
petition on November 7, 1997.  An order of this court, dated 
January 27, 1998, consolidated the defendant's direct appeal 
with his subsequent petition for a certificate of appealability 
under 28 U.S.C. s 2253 (1996), necessary to appeal the denial 
of his s 2255 motion.

     In this consolidated appeal, the defendant challenges his 
conviction on the basis of alleged errors made by the district 
court in (1) holding that the defendant had made a knowing 
and voluntary waiver of his rights under Rule 11(e)(6) of the 
Federal Rules of Criminal Procedure and Rule 410 of the 
Federal Rules of Evidence, such that statements made during 
his plea hearing and subsequent debriefing could be offered 
into evidence by the prosecution;  (2) allowing evidence of the 
defendant's prior conviction for attempted cocaine distribu-
tion into evidence under Rule 404(b) of the Federal Rules of 
Evidence;  and (3) denying a motion to suppress the fruits of 
an August 11, 1995 search by officers of the Metropolitan 
Police Department on the grounds that its execution at 11:00 



p.m. violated federal law.  He further asserts that his trial 
counsel was constitutionally ineffective for failing to seek a 
judicial hearing to enforce the terms of a plea agreement 
signed by appellant and the United States Attorney's Office, 
and for failing to complete the impeachment of a government 
witness.  Finally, he alleges that the prosecutor knowingly 
sponsored false or misleading testimony by the same govern-
ment witness, and that this instance of prosecutorial miscon-
duct materially affected the outcome of his trial.1  Finding no 
merit in any of these claims, we affirm the conviction and 
deny the request for a certificate of appealability.

                                I. Background

     In August of 1995, a confidential informant notified the 
Metropolitan Police Department ("MPD") that crack cocaine 
was being sold out of a residence at 446 N Street in north-
west Washington, D.C.  In order to verify the allegation, the 
MPD arranged for this "special employee" to make a con-
trolled purchase of narcotics from that location.2  When the 
purchased substance tested positive for cocaine base, MPD 
Sergeant Gerald G. Neill procured a warrant that authorized 
a search of the premises "in the daytime/at any time of the 
day or night."  Before executing the warrant at approximate-
ly 11:00 p.m., Sergeant Neill and his fellow officers set up and 
observed a second controlled purchase.  After the special 
employee handed MPD funds over to a figure who then 
retreated into the house, the police officers announced their 
presence and proceeded to conduct their search.

__________
     1 Appellant makes a number of further claims, none of which 
warrant discussion.

     2 In the typical controlled buy, police officers will give a special 
employee money with which to make a narcotics purchase.  After 
first searching that individual to ensure that he has neither money 
nor drugs on his person, the officers will give him police department 
dollars and then observe the consummation of the intended transac-
tion.  Upon the special employee's return, the officers conduct a 
second search so as to verify that the police money has been 
exchanged for narcotics.



     Through the open front door, Sergeant Neill observed a 
woman descending the interior staircase, before halting her 
downward progress and sprinting back up the stairs.  He 
followed the woman into an upstairs bedroom, where he found 
and, after a brief altercation, subdued both the woman--
Oneida Bailey ("Bailey")--and the defendant.  At that time, 
Sergeant Neill and the two other officers conducted their 
search of the premises, discovering:  plastic bags containing 
rocks of crack cocaine packaged in an eighth of an ounce 
quantities commonly referred to as "eight balls," smaller 
rocks of crack cocaine wrapped in plastic bags, two ziploc 
bags containing cocaine powder, other plastic bags of various 
sizes, a razor blade, a scale, and eight hundred and thirty 
dollars, which included the MPD funds used by the special 
employee.  In total, the MPD recovered 50.58 grams of 
cocaine base and 1.16 grams of cocaine powder.  From the 
bedroom, the police also seized two photographs of the defen-
dant, as well as several forms of identification containing his 
name and the 446 N Street address.

     Following his arrest, Burch entered into plea negotiations 
with members of the United States ("U.S.") Attorney's Office, 
culminating in an October 25, 1995 agreement in which he 
pled guilty to possession with intent to distribute more than 
50 grams of crack cocaine, count two of his four-count indict-
ment.  Burch also agreed to assist law enforcement authori-
ties whenever and in whatever form the U.S. Attorney's 
Office deemed appropriate.  In return, the government 
agreed to request the dismissal of the other three counts of 
the indictment, to allow the defendant's presentence release 
into the community to assist in undercover operations, and to 
inform the U.S. Attorney's Departure Guideline Committee of 
the nature and extent of the defendant's cooperation.  Should 
the Departure Committee determine that the defendant had 
rendered substantial assistance to the investigation and pros-
ecution of another individual, it would file a motion pursuant 
to 18 U.S.C. s 3553(e) (1994) in order to allow the sentencing 
judge to depart downwards from the federal sentencing 
guidelines.



     Burch, however, did not prove particularly cooperative, 
despite being informed by the trial judge on several occasions 
that he faced a mandatory minimum sentence of twenty years 
if he did not provide some opening for a downward departure 
by assisting the government.  He did outline the history of 
his involvement in narcotics distribution in a debriefing ses-
sion with the Drug Enforcement Agency ("DEA"), discussing 
the identity of his sources as well as the quantities of crack 
cocaine that he typically purchased from them, but not much 
more.  The defendant's name came up in relation to a homi-
cide in May and June of 1996 and, at the government's 
request, the court revoked his bond and detained him pending 
sentencing.  When questioned about the homicide, Burch was 
not forthcoming, and told a story which he subsequently 
recanted.  On July 22, 1996, the Assistant U.S. Attorney 
supervising the case filed a memorandum with the Departure 
Committee outlining the limited nature of Burch's coopera-
tion.  Eight days later, the defendant's trial counsel filed a 
motion seeking to withdraw the guilty plea and alleging 
Burch's innocence of the underlying narcotics offense.  In the 
motion, as well as in an August 1, 1996 letter addressed to the 
trial judge, Burch disavowed any knowledge of the drugs 
prior to their discovery by the MPD, and asserted that the 
cocaine belonged to Bailey.  He explained his guilty plea as a 
product of threats by Bailey to implicate him as a part of her 
own cooperation agreement with the government, coupled 
with a belief that a jury would be more likely to credit her 
testimony over his denial, given his status as a young black 
male with a prior arrest for possession with intent to distrib-
ute crack cocaine.3

     After a hearing, the trial court judge ultimately allowed 
Burch to withdraw his plea pursuant to Rule 32(e) of the 
Federal Rules of Criminal Procedure.  "Implausible as Mr. 
Burch's belated claim of innocence may seem, the Court will

     3 Appellant was arrested on June 5, 1994, on the same block as 
the 446 N Street residence, for possessing 18 ziploc bags containing 
crack cocaine.  He later pled guilty to attempted possession with 
intent to distribute crack cocaine.



give Mr. Burch his day in court."  Memorandum Opinion and 
Order, United States v. Burch, Crim. No. 95-225-01, at 5-6 
(D.D.C. Oct. 8, 1996) ("Mem. Op.").  However, as part of its 
decision, the court stated that it would not allow him to 
benefit from Federal Rules of Criminal Procedure Rule 
11(e)(6) and Federal Rules of Evidence Rule 410's restriction 
on the admissibility of statements made pursuant to a with-
drawn plea.  Id. at 6.  In his plea agreement, as well as in a 
Rule 11 colloquy with the trial judge prior to entering the 
plea, Burch specifically had waived his rights under Rules 
11(e)(6) and 410.  In allowing him to withdraw the plea, the 
trial court announced its intention to hold the defendant to 
this part of the agreement.  See id. at 6-7.  The court 
ultimately ruled that statements made by appellant during 
the October 25, 1995 plea hearing and a January 22, 1996 
debriefing with the DEA could be used as part of the 
prosecution's case-in-chief, while those made during plea ne-
gotiations taking place on October 24, 1995 could only be used 
for rebuttal or impeachment purposes should the defendant 
contradict them while on the witness stand.

     After a three-day trial, a jury convicted the defendant of 
possession with intent to distribute more than 50 grams of 
crack cocaine, while acquitting him of conspiracy to do the 
same.  The trial judge subsequently imposed a sentence of 
one hundred fifty one months imprisonment, to be followed 
by five years of supervised release.

                                II. Discussion


A.Appellant's Evidentiary Challenges

     1.The Withdrawn Plea

          a. Waiver

     Federal Rule of Criminal Procedure 11(e)(6) and Federal 
Rule of Evidence 410 each restrict the admissibility in a trial 
of a guilty plea previously withdrawn, as well as any state-
ments made during the discussions leading up to such a plea.  
Appellant challenges the legality of his waiver of these rights 
as a part of his guilty plea, asserting that he entered into the 


plea agreement involuntarily.4  Appellant contends that Bai-
ley threatened to testify against him, and that he feared a 
trial wherein her false testimony could lead to his conviction 
on all four counts of his indictment.  To avoid this jeopardy, 
he claims, he accepted the U.S. Attorney's offer to plead 
guilty to a single offense.  Before reaching the question of 
the voluntariness of the plea, however, we must first deter-
mine whether and for what purposes an individual can waive 
the protections contained in Rules 11(e)(6) and 410.

     The Supreme Court provided a partial answer in United 
States v. Mezzanatto, 513 U.S. 196, 201 (1995), where it held 
that the "provisions of those Rules are presumptively waiva-
ble...." Since "[a] criminal defendant may knowingly and 
voluntarily waive many of the most fundamental protections 
afforded by the Constitution," id., the Court reasoned that 
evidentiary rules should be subject to a similar presumption.  

__________
     4 Rules 11(e)(6) and 410 restrict the admissibility of "any state-
ment made in the course of plea discussions ...," which appellant 
interprets to encompass the October 24th plea negotiations, the 
October 25th plea agreement, and the January 22nd DEA debriefing.  
Because the trial judge only admitted the plea agreement and the 
debriefing statements into evidence as part of the prosecution's 
case-in-chief, the discussion of extending United States v. Mezza-
natto, 513 U.S. 196 (1995), contained in this subsection only refers 
to those two items, and not to the plea negotiations.  Moreover, the 
Eighth, Tenth, and Eleventh Circuits have each held that state-
ments made after a plea agreement is reached are not entitled to 
the Rules' protections, see United States v. Watkins, 85 F.3d 498, 
500 (10th Cir.), cert. denied, 117 S. Ct. 269 (1996);  United States v. 
Lloyd, 43 F.3d 1183, 1186 (8th Cir. 1994);  United States v. Knight, 
867 F.2d 1285, 1288 (11th Cir. 1989), reasoning that "[o]nce a plea 
contract is formed, the policy behind Rule 11(e)(6)--to allow a 
defendant to freely negotiate without fear that statements will be 
used against him--is no longer applicable."  Id.  Interpreting an 
earlier version of Rule 11(e)(6), before a 1979 amendment estab-
lished its current form, this court drew a similar distinction.  See 
United States v. Davis, 617 F.2d 677, 685 (D.C. Cir. 1979).  Here, 
since we conclude that appellant waived the protections extended by 
Rules 11(e)(6) and 410, we need not determine whether they would 


While evidence of fraud or coercion can invalidate waiver 
agreements, "absent some affirmative indication that the 
agreement was entered into unknowingly or involuntarily, an 
agreement to waive the exclusionary provisions of the plea-
statement Rules is valid and enforceable."  Id. at 210.

     As expansive as this language sounds, the Supreme Court 
faced a narrower question in Mezzanatto than that which we 
confront today.  There, the prosecutor had required, as a 
precondition to conducting plea negotiations, that the accused 
agree to allow the use of any statements made over the 
course of their discussions to impeach any contradictory 
testimony given in the case of a trial.  When the negotiations 
faltered, the government prosecuted Mr. Mezzanatto for pos-
session with intent to distribute methamphetamine, and he 
took the stand as part of his defense.  On direct examination, 
Mezzanatto denied having knowledge that the package he 
sold to an undercover officer contained methamphetamine.  
On cross-examination, and later with rebuttal witnesses, the 
prosecutor impeached this testimony with Mezzanatto's state-
ments made during the plea negotiations.  See id., at 198-99.  
On appeal, then, the Supreme Court only had to decide 
whether the protections contained in Rules 11(e)(6) and 410 
could be waived for purposes of impeachment or rebuttal.  In 
the case at bar, by contrast, the district court allowed the 
defendant's plea statement, as well as the conversations he 
had during the January 22nd debriefing session with the DEA, 
into evidence as a part of the prosecution's case-in-chief.  See 
12/4/96 Trial Tr. at 29-30.

     Although we face here the additional question of whether a 
defendant's Rule 11(e)(6) rights can be waived for purposes of 
the prosecution's case-in-chief, our inquiry still begins with 
Mezzanatto.  Justice Thomas' opinion paints with broad 
brush strokes, and its reasoning resonates beyond the precise 
question upon which it ruled.  In a one paragraph concurring 
opinion, Justice Ginsburg, joined by Justices O'Connor and 
Breyer, cautioned that the Mezzanatto decision did not ad-
dress the question of whether a waiver of Rule 11(e)(6) for 
purposes of the prosecution's case-in-chief would be valid.  
The concurrence raised the question of whether "a waiver to

plea agreement had been reached.

use such statements in the case-in-chief would more severely 
undermine a defendant's incentive to negotiate," 513 U.S. at 
211 (Ginsburg, J., concurring), than the waiver for impeach-
ment purposes sanctioned by the Court's decision, thereby 
presenting a more pressing public policy justification for 
disallowing a presumption of waivability.

     On reflection, however, we cannot discern any acceptable 
rationale for not extending the majority opinion in Mezzanat-
to to this case.  Justice Thomas' opinion rests on three 
principles.  First, it finds that in the absence of an affirmative 
indication that Congress intended to preclude or to limit the 
waiver of statutory protections, including evidentiary rules, 
voluntary agreements to waive these protections are pre-
sumptively enforceable.  See Mezzanatto, 513 U.S. at 201-02.  
Second, the opinion rejects the argument that Rules 11(e)(6) 
and 410, as well as the Advisory Committee's Notes which 
accompany them, express congressional disfavor towards 
waivability.  See id. at 208 n.5.  Finally, the opinion stresses 
that in weighing whether to override a presumption of waiva-
bility, a court should assess the public policy justifications, if 
any, which counsel in favor of departing from that norm.  See 
id. at 204-10.  Cumulatively, we believe these principles do 
not countenance drawing any distinction in this case between 
permitting waivers for purposes of impeachment or rebuttal 
and permitting waivers for the prosecution's case-in-chief.

     There are two arguments in favor of restricting the reach 
of Mezzanatto to rebuttal and impeachment.  They go like 
this:  First, in enacting Rules 11(e)(6) and 410, Congress has 
signaled an intent to create rights that benefit both the 
accused and the federal judicial system.  Although most 
personal rights are presumptively waivable, when rights 
serve as a surrogate for protecting institutional interests, the 
economic model of bargaining, see United States v. Wenger, 
58 F.3d 280, 282 (7th Cir. 1995) ("Right holders are better off 
if they can choose between exercising the right and exchang-
ing that right for something they value more highly.") does 
not suffice.  The Advisory Committee's Notes reference both 
individual and systemic concerns, describing the purposes 
behind the two rules as not to "discourage defendants from 



being completely candid and open during plea negotiations," 
and "to permit the unrestrained candor which produces effec-
tive plea discussions."  Fed. R. Crim. P. 11 Advisory Commit-
tee's Note (1979) (internal citations omitted).  If extending 
Mezzanatto would undermine Congress' attempt to promote 
candid plea discussions, deference to congressional intent 
could counter the presumption of waivability.  We think that 
there is a ready answer to this argument:  the Mezzanatto 
Court declined to read the Notes as mandating any default 
rule against waiver, a position that Justice Souter staked out 
in dissent.  See 513 U.S. at 214 (Souter, J., dissenting) ("Since 
the zone of unrestrained candor is diminished whenever a 
defendant has to stop to think about the amount of trouble his 
openness may cause him if the plea negotiations fall through, 
Congress must have understood that the judicial system's 
interest in candid plea discussions would be threatened by 
recognizing waivers under Rules 410 and 11(e)(6).").  Accord-
ing to the Court, "[t]he Advisory Committee's Notes always 
provide some policy justification for the exclusionary provi-
sions in the Rules, yet those policies merely justify the default 
rule of exclusion;  they do not mean that the parties can never 
waive the default rule."  Id. at 208 n.5.  Since the Supreme 
Court has already rejected congressional intent to promote 
candor as a justification for refusing to enforce voluntary 
waivers of these Rules in rebuttal, any argument relying on 
that intent is too weak to justify refusing to allow use of the 
plea statement in the government's case-in-chief.  In any 
event, the waiver in this case was part of the plea agreement;  
it resulted from successful plea negotiations.  During the 
negotiations, the defendant was protected by Rules 11(e)(6) 
and 410.  Thus, it is difficult to see how the waiver in this 
case could have reduced the "zone of unrestrained candor" 
during negotiations, as the waiver in Mezzanatto, which was 
secured by the prosecutor at the start of bargaining, arguably 
did.

     Second, while it is conceivable that sanctioning waivers for 
the use of statements made during plea proceedings in the 
prosecution's case-in-chief, as opposed to impeachment or 
rebuttal, could have a markedly greater impact on the willing-



ness of defendants to participate in such negotiations, the 
three-Justice concurrence in Mezzanatto presents no reason 
why that would be the case.  Nor has the appellant.  Lacking 
any evidence to the contrary, it seems unlikely to us that 
most defendants would draw fine distinctions as to whether 
statements made in the course of or after the plea proceeding 
could be used in the government's case-in-chief or only in 
rebuttal.  It is true that the three concurring Justices in 
Mezzanatto, whose votes were necessary for the majority, 
expressed concern that admitting plea negotiation statements 
in the case-in-chief would too severely undermine the defen-
dant's incentives to negotiate.  See id. at 211.  Such concern 
is far less warranted with respect to a waiver, like the one in 
this case, which is executed as a result of plea negotiations, 
rather than as a condition for such negotiations. In any event, 
allowing the government to bargain for a waiver during plea 
negotiations certainly does not undermine the reliability of 
the fact-finding process, the only institutional concern cited 
by Mezzanatto as a potential counterweight to the presump-
tion in favor of waivability.  See id. at 204 (some evidentiary 
provisions are so fundamental that permitting their waiver 
would discredit the integrity of the federal judicial process;  
"if the parties stipulated to trial by 12 orangutans the defen-
dant's conviction would be invalid notwithstanding his con-
sent") (citations omitted).  As a result, we can discern no 
reason not to uphold the trial judge's ruling in this case that a 
defendant can waive his rights under Rules 11(e)(6) and 410 
to the extent of allowing statements made in the plea pro-
ceeding itself and in a subsequent debriefing to be used as 
part of the prosecution's case-in-chief.

     b. Knowing and Voluntary

     Having decided that a defendant can affirmatively waive his 
rights under Rules 11(e)(6) and 410 to allow his plea state-
ment to be admitted into evidence, we move on to appellant's 
more basic contention that his waiver was involuntary.  Be-
fore any waiver can be deemed unenforceable, Mezzanatto 
held that a trial judge must find "some affirmative indication 
that the agreement was entered into unknowingly or involun-
tarily."  Id. at 210.  For this indication, appellant relies on 



the district court's decision to permit him to withdraw his 
plea, alleging that it represents an implicit finding of involun-
tariness.5  The district court, however, gave no such indica-
tion.  It characterized appellant's belated assertion of inno-
cence as both "implausible" and "hard to accept," Mem. Op. 
at 5, and decided to grant him the opportunity to present his 
case before a jury primarily because a trial represented 
appellant's "only chance to avoid the draconian sentence 
adopted by Congress for possession of crack cocaine by one 
previously convicted of a drug offense."  Id. at 6.  Moreover, 
it specifically warned him that it would allow all of appellant's 
plea statements into evidence for impeachment, rebuttal, or 
the case-in-chief in any future trial, an act that belies any 
view that the plea or the waiver were coerced.

     "This court reviews a trial judge's admission of evidence for 
abuse of discretion," United States v. Smart, 98 F.3d 1379, 
1386 (D.C. Cir. 1996), cert. denied, 117 S.Ct. 1271 (1997) 
(citing United States v. Salamanca, 990 F.2d 629, 637 (D.C. 
Cir.), cert. denied, 510 U.S. 928 (1993));  that standard is 
easily satisfied here.  Neither the Rule 11 plea colloquy 
between the trial judge and appellant, nor the judge's order 
permitting appellant to withdraw the plea, support in any way 
appellant's contention that the plea itself was entered into 
involuntarily.  The trial court asked the appellant "has any-
body threatened you or forced you in any way to enter this 
plea of guilty?"  10/25/95 Tr. at 17.  "And are you pleading 

__________
     5 Appellant's specific contention that he involuntarily waived the 
protections of Rules 11(e)(6) and 410 derives from his broader claim 
that he did not enter into the plea agreement voluntarily.  He 
makes no attempt to deconstruct the plea agreement into individual 
components, nor to claim that he acceded to a particular provision 
involuntarily, independent of his intention with respect to the entire 
plea.  Therefore, we can only review whether his waiver was 
knowing and voluntary through examining, as the trial court did, 
the nature of the plea agreement that subsumes it.  By contrast, 
the waiver addressed in Mezzanatto had been negotiated separate-
ly, before the plea discussions began.  Therefore, the Mezzanatto 
Court could focus specifically on the voluntary nature of the waiver 
of the nonadmissibility guarantees.



guilty voluntarily and because you are guilty?"  Id. at 19.  
Appellant answered both questions in the affirmative.  The 
trial judge also went through the specific terms of the plea 
agreement with appellant, including the provision in which he 
waived his rights under Rules 11(e)(6) and 410.  When subse-
quently challenged, the judge characterized appellant's waiver 
of his rights under Rules 11(e)(6) and 410 as "knowing and 
voluntary," Mem. Op. at 7, and rejected the defendant's 
motion to suppress on the grounds that "[t]here was nothing 
wrong with the plea proceeding.  There was nothing wrong 
with [appellant's] understanding of what was going on.  He 
made the statements.  He made those statements under 
oath."  12/3/96 Trial Tr. at 75.  The extensive colloquy con-
ducted by the trial court clearly supports this determination 
that appellant knowingly and voluntarily waived his rights 
under Rules 11(e)(6) and 410.  In no way could such a 
decision to permit the plea statement and the debriefings into 
evidence constitute an abuse of discretion.

     Our ruling is in accord with our own precedent.  In United 
States v. Cray, 47 F.3d 1203 (D.C. Cir. 1995), the defendant 
sought to withdraw his plea as the product of coercion due to 
a co-defendant's alleged threats to testify against him in 
return for a lesser sentence.  See id. at 1205.  We refused to 
characterize the plea as involuntary, explaining that before 
accepting his guilty plea, the trial court judge had conducted 
a "textbook Rule 11 inquiry, taking pains to insure that the 
defendant's submissions were knowing and voluntary."  Id. at 
1208.  Since the trial judge's voluntariness determination 
ultimately rested upon a credibility finding, this court refused 
to disturb it absent clear evidence to the contrary.  Id. at 
1209 (citing the clearly erroneous standard utilized in United 
States v. Lloyd, 868 F.2d 447, 451 (D.C. Cir. 1989)).  See also 
United States v. Hernandez, 79 F.3d 1193, 1195 (D.C. Cir. 
1996) (where the trial court conducted an extensive Rule 11 
colloquy and a hearing on the defendant's plea withdrawal 
motion, there is no reason to cast doubt on the court's 
conclusion that the plea was voluntary);  United States v. 
Woolley, 123 F.3d 627, 632-34 (7th Cir. 1997) (extensive and 



careful Rule 11 colloquy conducted prior to accepting defen-
dant's guilty plea fully supports determination that defendant 
accepted plea knowingly and voluntarily);  United States v. 
Clements, 992 F.2d 417, 418-19 (2d Cir. 1993) (extensive Rule 
11 allocution fully established the voluntariness of defendant's 
plea).

     2.Prior Bad Acts

     Appellant also challenges the district court's denial of his 
motion in limine to exclude evidence of his prior arrest and 
conviction for attempted possession with intent to distribute 
crack cocaine, arguing that this "other crimes" evidence was 
both irrelevant to the charges against him and more prejudi-
cial than probative.  In addressing trial court determinations 
on the admissability of bad acts evidence under of the Feder-
al Rules of Evidence, this circuit has employed a two-step 
mode of analysis.  Under the first step, which addresses Rule 
404(b), "we must determine whether the evidence is relevant 
to a material issue other than character."  United States v. 
Mitchell, 49 F.3d 769, 775 (D.C. Cir. 1995) (citations omitted).  
See also Huddleston v. United States, 485 U.S. 681, 686 
(1988) ("The threshold inquiry a court must make before 
admitting similar acts evidence under Rule 404(b) is whether 
that evidence is probative of a material issue other than 
character.").  "If so, we proceed to the second inquiry," under 
Federal Rule of Evidence 403, "whether the probative value 
is substantially outweighed by the prejudice."  Mitchell, 49 
F.3d at 775.

     Here, appellant was tried for possession with intent to 
distribute more than 50 grams of crack cocaine and conspira-
cy to possess and distribute the same.  To establish the 
requisite elements on the possession count, the government 
needed to prove that appellant possessed crack cocaine know-
ingly and intentionally, and that when he possessed the 
cocaine he had a specific intent to distribute it.  See 21 U.S.C. 
s 841(a)(1).  In making the Rule 404(b) determination, the 
trial judge concluded that "[t]he fact is that the evidence [of 
appellant's prior conviction] is relevant to show knowledge 
and intent which are elements that the Government must 
prove....  It's within the very same block and it involved 



again crack cocaine.  And his knowledge and intent with 
respect to crack cocaine is what is at issue here."  12/3/96 
Trial Tr. at 42.  Since the evidence of appellant's prior 
conviction went beyond the issue of character, and went to 
the issues of knowledge and intent which formed the basis of 
appellant's trial defense, the prior conviction satisfies the first 
step of the Mitchell analysis.  See United States v. Harrison, 
679 F.2d 942, 948 (D.C. Cir. 1982) ("The intent with which a 
person commits an act on a given occasion can many times be 
best proven by testimony or evidence of his acts over a period 
of time prior thereto....");  United States v. Crowder, 141 
F.3d 1202, 1208 n.5 (D.C. Cir. 1998) (in banc) ("A defendant's 
hands-on experience in the drug trade cannot alone prove 
that he possessed drugs on any given occasion.  But it can 
show that he knew how to get drugs, what they looked like, 
where to sell them, and so forth.").

     The second step of the analysis takes place under Rule 403, 
and involves balancing the probative value of other crimes 
evidence against its prejudicial effect upon the defendant.  
See Fed. R. Evid. 403.  Because this balancing involves a 
highly subjective assessment, this court conducts its review 
under a "grave abuse of discretion" standard.  See Mitchell, 
49 F.3d at 776.  Here, the trial judge was clearly aware of the 
potential danger for "jury misuse of the evidence," United 
States v. Brown, 490 F.2d 758, 764 (D.C. Cir. 1973), and 
crafted a careful limiting instruction to guide the jury away 
from drawing a conclusion on the basis of character or 
propensity.  Given the likeness of the allegations, the similar 
mode of packaging the crack cocaine for distribution, the 
coincidence of the locations involved, and the corroboration 
provided by appellant in his debriefing session with the DEA, 
there is "no compelling or unique evidence of prejudice in this 
case that warrants upsetting the trial court's determination." 
United States v. Washington, 969 F.2d 1073, 1081 (D.C. Cir. 
1992).

B.The Validity of the Warrant as Executed

     Appellant also challenges the trial court's decision to permit 
the fruits of the MPD search into evidence, attacking the 



legal validity of both the underlying warrant and its nighttime 
execution.  While appellant contends that the validity of the 
warrant's execution must be measured against federal stan-
dards because "a federal offense has been charged and the 
trial was held in federal court," Appellant's Br. at 28, we need 
not decide whether the warrant is federal or local, nor need 
we choose between the federal and the local law standard to 
measure the legality of its execution.  The warrant and its 
nighttime execution were valid under either regime.

     Beginning with federal law, Rule 41 of the Federal Rules of 
Criminal Procedure directs that a "warrant shall be served in 
the daytime, unless the issuing authority, by appropriate 
provision in the warrant, and for reasonable cause shown, 
authorizes its execution at times other than daytime."  Fed. R. 
Crim. P. 41(c)(1).  See also Fed. R. Crim. P. 41(h) (defining 
"daytime" as "the hours from 6:00 a.m. to 10:00 p.m. accord-
ing to local time").  Nevertheless, in the face of a specific 
statutory regime for an articulated class of offenses, the 
general provisions contained in Rule 41 are displaced.  See 
United States v. Berry, 113 F.3d 121, 123 (8th Cir. 1997) 
(holding that s 879 governs search for marijuana, rather than 
Rule 41);  Mason v. United States, 719 F.2d 1485, 1489 (10th 
Cir. 1983) (interpreting Wyoming parallels to Rule 41 and 
s 879 such that the specific statutory provisions sanctioning 
nighttime search for controlled substances apply);  United 
States v. Alatishe, 616 F. Supp. 1406, 1411 (D.D.C. 1985) 
("Where there is a specific statute relating to the issuance 
and execution of search warrants, that particular statute as a 
general matter controls over any more diffuse search warrant 
legislation or policy.").  This case provides an example.

     21 U.S.C. s 879 instructs that a "search warrant relating to 
offenses involving controlled substances may be served at any 
time of the day or night if the judge or United States 
magistrate issuing the warrant is satisfied that there is 
probable cause to believe that grounds exist for the warrant 
and for its service at such time."  In Gooding v. United 
States, 416 U.S. 430 (1974), the Supreme Court addressed the 
interaction between Federal Rule of Criminal Procedure 41 



and then 21 U.S.C. s 879(a).6 After noting that Rule 41 had 
been amended subsequent to the passage of s 879(a), the 
Court went on to hold that "Congress, as it had in the earlier 
version of the Rule, nevertheless showed its clear intention to 
leave intact other special search warrant provisions, includ-
ing, of course, the provisions relating to searches for con-
trolled substances."  Id. at 453-54.

     The Gooding Court confronted a fact pattern analogous to 
the present case.  There, an Assistant United States Attor-
ney had sought a warrant authorizing a search for narcotics, 
and in support of his application presented an affidavit signed 
by an undercover MPD officer alleging knowledge of the 
possession and sale of drugs.  The defendant challenged the 
validity of the warrant for a search "at any time in the day or 
night," 416 U.S. at 442, alleging that the magistrate failed to 
make a special showing of need for its nighttime execution.  
In the present case, appellant similarly reads the final clause 
of s 879--requiring "that there is probable cause to believe 
that grounds exist for the warrant and for its service at such 
time"--as creating an obligation on the part of the govern-
ment to establish probable cause for a nighttime search.  
While this certainly constitutes a plausible reading of the 
statutory language, the Supreme Court has explicitly rejected 
it.  Speaking directly to the issue, the Court concluded "that 
21 U.S.C. s 879(a) requires no special showing for a night-
time search, other than a showing that the contraband is 
likely to be on the property or person to be searched at that 
time."  Id. at 458.7  Just as the prior controlled buy provided 

__________
     6 A 1974 amendment to 21 U.S.C. s 879(a) struck out the designa-
tion (a);  the statutory provision at issue in Gooding and in the 
present case are identical.  See Pub. L. No. 93-481, s 3, 88 Stat. 
1455 (1974).

     7 In the present case, the district court judge assumed that in the 
absence of a finding of time-related probable cause, a nighttime 
search for narcotics could only be valid under District of Columbia 
law.  While the district court judge believed that a search pursuant 
to 21 U.S.C. s 879 required that "an additional finding must be 
made by the Magistrate before authorizing a nighttime execution of 



the requisite "showing" in Gooding, so too does the previous 
purchase of crack from the 446 N Street residence legitimate 
the MPD's subsequent nighttime search under federal law.

     Under District of Columbia law, the analysis comes out the 
same.  The District of Columbia Code parallels federal law, in 
that it contains a background warrant provision in Title 23 
s 521,8 as well as a particular provision directed at controlled 
substances in Title 33 s 565.9  In United States v. Thomas, 
294 A.2d 164, 167-68 (D.C. 1972), cert. denied, 409 U.S. 992 
(1973), the District of Columbia Court of Appeals determined 
that the specific provisions contained in Title 33 of the D.C. 
Code are neither superceded nor qualified by the more 
general provisions contained in Title 23.  As both the warrant 
in question and its underlying affidavit each assert a belief 
that cocaine is being sold from the premises at 446 N Street, 
the more specific provisions contained in D.C. Code 
s 33-565(h) would apply.  Moreover, the District of Columbia 
Court of Appeals has also held that "once a judge has 
determined that probable cause exists to search for drugs in 
the District of Columbia, a search warrant may be issued.  
Such a warrant may be executed at any time of the day or 
night."  Hines v. United States, 442 A.2d 146, 148 (D.C. 
1982).10  According to the Court of Appeals, once a probable 

__________
a warrant," 12/3/96 Trial Tr. at 66-67, Gooding specifically holds to 
the contrary.

     8 "A search warrant shall contain ... a direction that the warrant 
be executed during the hours of daylight or, where the judicial 
officers have found cause therefor, including one of the grounds set 
forth in section 23-522(c)(1), and authorization for execution at any 
time of day or night."  D.C. Code Ann. s 23-521(f)(5) (1997).

     9 "The judge or Magistrate shall insert a direction in the warrant 
that it may be served at any time in the day or night."  D.C. Code 
Ann. s 33-565(h) (1997).

     10 In Hines, a warrant office clerk, acting without instructions, 
crossed out the 'at any time of the day or night' provision on the 
warrant form.  The Court of Appeals held that this inadvertent 
ministerial mistake did not render the subsequent nighttime search 
invalid.  Id. at 149.


cause determination has been made, the issuing judge must 
insert the "any time during the day or night" directive.  "The 
language [of D.C. Code s 33-565(h)] is mandatory."  Id. at 
149.

     As both federal and local law specifically provide for night-
time narcotics searches, appellant's argument stands or falls 
on its contention that the ambiguity resulting from Sergeant 
Neill's failure to cross out the warrant's "daytime" clause 
renders it invalid.  Since neither of the potentially applicable 
standards contain a time restriction, we do not believe that 
this ministerial oversight in any way undermines the war-
rant's validity.  Additionally, Sergeant Neill acted in good 
faith.  His belief, as the district court found it, "that he could 
execute it at any time of the day or night since this was a 
drug warrant ...," 12/3/96 Trial Tr. at 60, satisfies the 
"objectively reasonable" test articulated in United States v. 
Leon, 468 U.S. 897, 922 (1984).

C.Appellant's Petition for a Certificate of Appealability

     Under 28 U.S.C. s 2253(c)(1)(B), an appeal cannot be taken 
from a final order in a s 2255 habeas corpus proceeding 
unless a circuit judge issues a certificate of appealability.  28 
U.S.C. s 2253(c)(2) provides that a certificate may issue "only 
if the applicant has made a substantial showing of the denial 
of a constitutional right."

     1.Ineffective Assistance of Counsel

     In his s 2255 habeas corpus proceeding, appellant main-
tained that his trial counsel failed to satisfy the constitutional-
ly prescribed minimum standard for effectiveness.  He con-
tinues to press this claim in his petition for a certificate of 
appealability, challenging his counsel's failure:  (i) to seek 
enforcement of the contractual plea agreement between ap-
pellant and the government, or at the very least to seek an 
evidentiary hearing through which appellant could establish 
that the government's refusal to file a 5K1.1 motion constitut-
ed a breach;  and (ii) to complete the impeachment of Oneida 
Bailey with the notes from her debriefing session with the 
DEA.  Because neither of these alleged inadequacies, wheth-



er considered individually or in aggregate, suffice to establish 
a claim for constitutional ineffectiveness under the standard 
articulated in Strickland v. Washington, 466 U.S. 668 (1984), 
we decline to issue a certificate of appealability for appellant's 
Sixth Amendment claim.

     In Strickland, the Supreme Court advised reviewing courts 
that they need not undertake both components of the ineffec-
tive assistance inquiry should it prove possible to dispose of a 
challenge on either of its prongs.  See id. at 697.  Appellant's 
first assertion, that trial counsel should have sought to en-
force the plea agreement, falters in its inability to make the 
requisite showing of prejudice--"that there is a reasonable 
probability that, but for counsel's unprofessional errors, the 
result of the proceeding would have been different."  Id. at 
694.  A cursory comparison of the plea agreement's terms 
with the actions taken by the U.S. Attorney's Office reveals 
that the government fulfilled all of its responsibilities under 
it.11  In particular, sections 9(d) and (e) provide that the 
prosecutor "will inform the Departure Guideline Committee 
of the United States Attorney's Office for the District of 
Columbia the nature and extent of [appellant's] cooperation, 
or lack thereof," and that he will file a motion pursuant to 18 
U.S.C. s 3443(e) and s 5K1.1 of the federal sentencing guide-
lines should the Departure Committee determine "that [ap-
pellant] had provided substantial assistance in the investiga-
tion or prosecution of another person who has committed any 
offense...." Appellee's App. at 022-23.  The Assistant U.S. 
Attorney involved in appellant's prosecution filed papers to 
apprise the Departure Committee of appellant's progress, and 
the Committee declined to authorize that any such motion be 
filed with the court.  Because the government complied with 

__________
     11 The plain language of the plea signed by Burch makes it clear 
that he himself breached the agreement, first by failing to "cooper-
ate truthfully, completely and forthrightly with [the U.S. Attor-
ney's] Office and other Federal, state and local enforcement author-
ities whenever, wherever, and in whatever form this Office deems 
appropriate,"--as required by section 3(a) of the plea--and later by 
filing a motion to withdraw his plea--an act which section 5(a) 
defines as a breach of the agreement.  See Appellee's App. at 20-21.



the terms of the plea agreement, no effort by appellant's 
counsel could have obtained an order for specific perfor-
mance.

     Appellant next faults his trial counsel for failing to impeach 
Bailey with notes from a DEA debriefing session.  At trial, 
appellant's defense centered around the argument that the 
drugs recovered by the MPD belonged to Bailey.  In addition 
to so testifying, appellant developed this theory by arguing 
that he no longer resided at the 446 N Street residence in 
August of 1995, that the bedroom in which the cocaine was 
discovered belonged to Bailey, that she had made numerous 
drug sales earlier that day, and that she had recently pur-
chased a quantity of cocaine similar to the amount recovered 
by the MPD.  Notes from Bailey's DEA debriefing session 
provided some support for the last contention, in that they 
contained an entry, under the heading "Phil ... Source of 
supply," that reads "62 grams--the most she's gotten from 
him."  Appellant's App. at 151.  When cross-examining Bai-
ley, appellant's trial counsel repeatedly asked whether she 
had ever obtained 62 grams of crack cocaine from Phil.12  

__________
     12 The exchanges read:

     Q:Didn't you once get 62 grams or something in that range 
     from a guy named Phil?
     A:Named Phil?
     Q:Yes.
     A:I didn't--I didn't get it from him but I know he had it.
     Q:Did you ever get 62 grams from him or get something of 
     that amount from Phil?
     A:No, but he sells it but I never got it from him.
     Q:But on other occasions you got drugs from Phil?
     A:Yes.
12/5/96 Trial Tr. at 33.
     Q:Did you ever--do you remember ever telling an investiga-
     tor at a meeting that you got 62 grams once from Phil?
     A:No.
     Q:Didn't you once tell an investigator that you got 62 grams 
     from Phil?
     A:I never got that amount from him, never.


Though she answered in the negative, defense counsel did not 
present her with a copy of the notes and ask her to explain 
any disparity between the text and her testimony.

     Appellant alleges that this failure by defense counsel to 
produce the notes and to "complete the impeachment," Appel-
lant's Br. at 36, of Bailey's testimony constitutes an oversight 
of constitutional magnitude.  We cannot agree.  Even if it 
constitutes a failure of advocacy,13 appellant's claim cannot 
negotiate the hurdle of Strickland's prejudice prong when 
examined in light of the record as a whole.  See Strickland, 
466 U.S. at 695-96 (court looks to evidence in its totality when 
assessing potential prejudice).  In addition to his earlier 
admission of guilt, the evidence marshaled against appellant 
was substantial.  Most important, the DEA agent who con-
ducted the January 22nd debriefing testified that appellant 
admitted to owning the crack cocaine seized by the MPD, and 
to having made his most recent buy just prior to his arrest.  

__________
     Q:Well, you never got an amount of that sort from Phil or 
     from--
     A:And I don't remember telling the investigator that.
     Q:You don't remember telling the investigator that either.
     A:No.
     Q:So you didn't get 62 grams from Phil or from anyone, is 
     that right?
     A:No, I did not.
     Q:And you don't remember telling any investigator that you 
     got 62 grams from Phil.
     A:No.
Id. at 70-71.
     13 The trial court denied appellant's s 2255 petition on the 
grounds that defense counsel acted reasonably:  "[W]ould a reason-
able effective counsel have showed her the debriefing note?  I'd say 
some would and some wouldn't."  11/7/97 Tr. at 50.  Since we find 
any effect of defense counsel's alleged errors insufficient to justify 
overturning the jury's verdict, and "[f]ailure to make the required 
showing of either deficient performance or sufficient prejudice 
defeats the ineffectiveness claim," Strickland, 466 U.S. at 700, we 
need not pass judgment on the reasonableness of counsel's perfor-
mance.



According to the DEA agent, appellant also described his 
source of cocaine base, the quantities he typically purchased 
and their cost, as well as his subsequent distribution.  When 
Bailey testified that the cocaine belonged to appellant, she 
merely corroborated evidence already presented to the jury 
by numerous law enforcement officials.

     Had defense counsel presented Bailey with the DEA de-
briefing notes and asked her to explain any disparity, that 
impeachment would not have cast any doubt on the testimony 
given by the various law enforcement witnesses.  Since the 
notes lack any temporal references about the 62 grams, even 
if it could have been established that Bailey once received 
that quantity of cocaine from a supplier named Phil, no 
evidence links that receipt with the drugs appellant repeated-
ly admitted to owning.14  As for its capacity to vitiate Bailey's 
credibility, we do not believe that the introduction of the DEA 
notes could have undermined her reliability significantly more 
than the testimony she had already given.  Bailey admitted 
that she was intoxicated with a controlled substance on the 
night of the arrest, that she had participated in narcotics 
transactions which provided the basis for the search warrant 
and her arrest, that she had been convicted of possession with 
intent to distribute in the past, that she was cooperating with 
the government in return for a lighter sentence, and that she 
had broken the terms of her own plea agreement by continu-
ing to use drugs and by being rearrested for heroin posses-
sion.  Viewed in light of the overwhelming evidence against 
appellant, including his previous admission not just of the fact 
but the details of his guilt, we cannot find that there is a 
reasonable probability that, had Bailey been confronted with 

__________
     14 The only temporal reference consists of the statement "last 
contact--$150 purchase 8-ball in August."  Appellant's App. at 151.  
Testifying at appellant's s 2255 hearing, the DEA agent who de-
briefed Bailey interpreted her notes to mean that any receipt of 62 
grams would have had to have taken place prior to August.  How-
ever, as she had no specific recollection of her conversation with 
Bailey, she could offer only her best reconstruction of the notes.



the DEA notes, the jury verdict would have been any differ-
ent.  See Strickland, 466 U.S. at 694.

     2.Prosecutorial Misconduct

     Finally, appellant asserts that the prosecutor violated his 
Fifth Amendment right to due process of law by knowingly 
sponsoring, or by failing to correct, the allegedly false testi-
mony of a government witness.  Rehearsing the substance of 
his ineffective assistance claim, appellant highlights the dis-
crepancy between Bailey's trial testimony and the DEA de-
briefing notes on the subject of whether she received drugs 
from Phil.  He goes on to argue that, under Napue v. 
Illinois, 360 U.S. 264 (1959), the prosecution had a duty to 
alert the court to Bailey's prior inconsistent statement.  See 
also United States v. Iverson, 637 F.2d 799, 803 n.10 (D.C. 
Cir. 1980) ("[T]he prosecutor had an independent responsibili-
ty to alert the Court and jury to the truth."), modified on 
petition for reh'g, 648 F.2d 737 (D.C. Cir. 1981).  Rather than 
pointing out the disparity, appellant alleges that the prosecu-
tion exacerbated the deception by leading Ms. Bailey through 
the following rehabilitating exchange:

     Q:Did you ever tell a DEA agent you thought a guy 
          named Phil might have 62 grams of crack?

     A:Yeah, when they asked.

12/5/96 Trial Tr. at 71.  From this alleged failure by the 
prosecution to fulfill its affirmative obligation to correct the 
record when a government witness testifies falsely, appellant 
deduces a violation of due process.  We disagree.

     Even if appellant could establish that the prosecution either 
sponsored or failed to correct false testimony,15 he cannot 
satisfy the materiality test for prosecutorial misconduct artic-

__________
     15 Without passing judgment on this question, we note that the 
district court, in addressing appellant's s 2255 motion, specifically 
concluded that the prosecutor did not knowingly sponsor false 
testimony. "We still don't know that this is false testimony....  
Nothing I've heard in the last two days indicates to me that there 
was false testimony given at trial."  11/7/97 Tr. at 20-21.

ulated in Napue and reiterated in Giglio v. United States, 405 
U.S. 150, 154 (1972) and United States v. Agurs, 427 U.S. 97, 
112-13 (1976).  Before finding an error of constitutional 
significance, Giglio directs that a reviewing court must deter-
mine whether "the false testimony could in any reasonable 
likelihood have affected the judgment of the jury."  Id. at 154 
(citations omitted).  Although the prosecutor and defense 
counsel have different obligations, in this instance we believe 
that our discussion of appellant's ineffective assistance of 
counsel claim effectively settles the issue.  Just as we cannot 
find a reasonable probability that the jury verdict would have 
differed had defense counsel confronted Bailey with the notes, 
we cannot discern a reasonable likelihood of a different 
judgment even if appellant's interpretation of the notes had 
been expressed to the jury.

     Appellant offers two theories as to how the prosecutor's 
allegedly improper question satisfies the Giglio materiality 
standard.  We reject each in turn.  First appellant asserts 
that if the jury had been apprised of the DEA notes, it could 
have equated the transaction referred to in the notes with the 
drugs seized by the MPD, whether or not Bailey admitted to 
receiving 62 grams of cocaine on the stand.  However, appel-
lant admitted ownership of these specific drugs not merely in 
his guilty plea, but also in his more detailed debriefing 
session with the DEA.  Moreover, Bailey did testify to pur-
chasing large amounts of crack cocaine on previous occasions.  
Even if the jury had been made aware that she told the DEA 
agent that she had received 62 grams from Phil at some 
point, we do not believe that this additional admission would 
have cast any appreciable doubt upon the solid evidence 
establishing appellant's guilt.  Second, appellant claims that 
the prosecutor's question served to rehabilitate Bailey's credi-
bility as a witness, such that the jury was more likely to 
credit her testimony against appellant.  However, at this 
point Bailey's credibility had been thoroughly compromised 
by her own admissions of prior drug use and dealing, and we 
doubt any attempt at rehabilitation--if that it was--through 
rephrasing a single question peripheral to the main issue of 



the trial could have influenced the jury in its final verdict.16 
See discussion infra pp. 23-24.

                               III. Conclusion

     For reasons explained, we reject all of Burch's contentions 
and affirm his conviction.  Because appellant has failed to 
make a substantial showing of the denial of any constitutional 
right, we decline to issue a certificate of appealability and 
affirm the dismissal of his petition for a writ of habeas corpus.

                                                                                     So ordered.

denied that they had been promised lenient treatment, see Giglio 
405 U.S. at 152-53, and a recommendation of a reduced sentence, 
see Napue, 360 U.S. at 266-67, in return for their testimony.
