A jury сonvicted Brannon L. Hatchett of distributing crack cocaine and of aiding and abetting Ms purchaser’s re-sale of the same cocaine to an informant and an undercover officer. Hatchett contends that his concurrent sentence on the aiding and abetting charge amounts to a second punishment for the same offense. He also challenges the admission of evidence concerning a prior narcotics transaction, as well as the district court’s refusal to admit certain fingerprint evidence. We conclude that Hatchett’s conviction and sentence on the aiding and abetting charge do not amount to an impermissible multiple punishment for a single offense. We also find no abuse of discretion in the admission of testimony concerning the prior drug transaction or in the exclusion of the fingerprint evidence.
I.
In reviewing Hatchett’s conviction, we are obligated to credit testimony and in *628 dulge inferences that benefit the prosecution. We therefore recount the facts in the light most favorable to the government.
Hatchett met John L. Riley at a Madison, Wisconsin nightclub in October of 1998, and shortly thereaftеr Hatchett began to sell crack cocaine to Riley. Typically, when Riley wanted to make a purchase, he would contact Hatchett either by paging him or by telephoning him at the apartment of Hatchett’s girlfriend, where Hatchett often stayed.
In November 1998, Tracy Panzer, whose brother was married to Riley’s sister, telephoned Riley to ask whether he could obtain an ounce of crack cocaine for himself and a friend. Unbeknownst to Riley, Panzer was working as a confidential informant with the Oneida County Sheriffs Department, and his “friend,” Dan Hess, was a deputy sheriff working undercover. After a number of telephone calls to Hatchett, Riley told Panzer that he had the cocaine Panzer and his friend wanted.
On November 24, 1998, Riley met Panzer and Hess at a PDQ near Riley’s apartment in Madison. Riley did not have the cocaine with him at that time, and explained to Panzer and Hess that he needed to telephone his “guy” in order to get it. Riley borrowed Hess’s cellular phone for that purpose and placed a call to the home of Hatchett’s girlfriend. After completing the call, Hatchett told the two men that they would have to wait awhile in order to complete the transaction. Panzer and Hess then drove Riley to his apartment complex. Riley invited them in to his apartment to wait for his source to deliver the cocaine. The two men declined, however, and Riley went up to this second-floor apartment alone. There he contacted Hatchett, arranged for delivery of the cocaine, and then telephoned Panzer and Hess to let them know that the narcotic was on its way.
A surveillance officer subsequently observed a car drive into the parking lot of the apartment complex, circle the lot, and then leave. Moments later Hatchett telephoned Riley and said that he thought there was “heat” in the vicinity of the apartment building. Riley assured him that everything was fine and encouraged him to come to his apartment. A short time later the same car that had circled and left the parking lot earlier returned and parked. A man later identified as Hatchett left the vehicle and entered Riley’s apartment building. No more than two minutes later, Riley telephoned Panzer and Hess to tell them that he had the cocaine and to name the price ($775) that he wanted. Panzer and Hess, who were waiting at a local shopping mall, drove back to Riley’s apartment complex. While they were en route, Riley left Hatchett in his apartment awaiting -payment and walked downstairs to the building entryway. He stopped there to collect his mail and to look outside in order to determine whether there might be any “heat” in the parking lot, as Hatchett had suspected. He satisfied himself that there was none. Impatient for Panzer and Hess to arrive, Riley telephoned them again wondering where they were. They assured him that they were on their way. In fact, they arrived almost immediately, parked in front of the apartment building, and spotted Riley waiting for them in the doorway. Riley walked over to Panzer’s car, got in the back seat, and handed to Hess a Marlboro cigarette package containing a substance that was later determined to be nearly 10 grams of crack cocaine.
Once Riley had delivered the cocaine, an arrest signal was given and officers moved in to arrest Riley. As they did so, Hess saw Hatchett standing on Riley’s second- *629 floor balcony. Hatchett, whо was ordered to remain where he was, tried to flee but was unsuccessful.
A grand jury indicted Hatchett on two charges. R. 11. As elucidated by the government’s subsequent bill of particulars (R. 81 at 2-3), Count One alleged that Hatchett knowingly and intentionally distributed crack cocaine-to Riley, in violation of 21 U.S.C. § 841(a)(1), while Count Two alleged that he aided and abetted Riley’s subsequent delivery of that same cocaine to Hess, in violation of 18 U.S.C. § 2 and 21 U.S.C. § 841(a)(1). Before trial, Hatchett moved to dismiss Count Two as multiplicitous, asserting that the indictment effectively charged him twice for the same crime. R. 22, 32. On the recommendation of the magistrate judge (R. 41), the district court denied the motion (R. 52). The court emphasized that the indictment charged Hatchett with participating in two distinct criminal transactions, his own initial distribution of cocaine to Riley, and Riley’s subsequent distribution of the cocaine to Hess. In order to prove Hatchett’s guilt on Count Two, the court pointed out, the government would have to establish that the second distribution from Riley to Hess took place, and that Hatchett knowingly associated himself with that second transaction, that he participated in it, and that he tried to make it sucсeed. R. 41 at 7, R. 52 at 3. Therefore, the court reasoned, the indictment did not charge Hatchett twice for the same offense.
The case proceeded to trial. Hatchett’s defense was that he was not Riley’s source of cocaine. Riley was a goldsmith, and Hatchett maintained that he associated with Riley solely because he believed he might be able to get jewelry at a discounted price. Indeed, Hatchett had introduced his cousin to Riley, and according to the defense, Riley was in the process of making some jewelry for his cousin in late November 1998. That was Hatchett’s explanation for his presence in Riley’s apartment on the evening of November 24, when he and Riley were arrested. (The police found no narcotics, no large sums of cash, and no drug paraphernalia either on Riley’s person or in his car.)
It turned out, however that there had been a prior cocaine transaction that brought Hatchett, Riley, and Tracy Panzer’s brother Robert together. In late October, 1998 (one month prior to the events culminating in Hatchett’s indictment), Riley had mentioned to Robert that he had a new source for crack cocaine. Robert expressed interest in obtaining some of the illicit drug from Riley’s source and asked Riley to make' appropriate arrangements. Robert drove to Riley’s apartment in Madison in order to retrieve the cocaine. After he arrived, Riley made a number of telephone calls to his source. After a three-hour wait, Hatchett arrived at Riley’s apartment. After Robert was introduced to Hatchett and the two had shaken hands, Riley and Hatchett went into a bathroom together. When they emerged, Riley turned over an “eight-ball” quantity of crack cocaine to Robert and kept a similar amount for himself. Hatchett then left the apartment. Over Hatchett’s objection, the district court permitted the government to elicit testimony from Robert about this October transaction, reasoning that the evidence was admissible under Fed.R.Evid. 404(b) in order to establish plan or preparation, knowledge, and opportunity. R. 79 at 14-19.
At the close of the defense case, Hatchett’s counsel offered an uncertified copy of a fingerprint analysis report issued by the Wisconsin Crime Laboratory. R. 80 at 268. That report indicated that the laboratory was unable to match to either Riley or Hatchett a latent fingerprint *630 found on a metal cigar box in which Hatchett had delivered the cocaine to Riley on November 24. Def. Ex. 4. Judge Shabaz declined to admit the report into evidence without an appropriate foundation. R. 80 at 269-72.
The jury convicted Hatchett on both counts of the indictment. Judge Shabaz ordered him to serve a prison term of 90 months, to be followed by a five-year term of supervised release. The judge did not impose a fine or any restitution obligation, but he did order Hatchett to pay a special assessment of $100 on each count of conviction.
II.
A.
The Double Jeopardy Clause of the Fifth Amendment provides that no “person [shall] be subject for the same offence to be twice put in jeopardy of life or limb.” U.S. Const., amend. V. Three separate guarantees inhere in this constitutional provision: (1) once acquitted of a charge, a person shall not be prosecuted again for the same offense; (2) once convicted of a crime, a person shall not be prosecuted again for that same crime; and (3) one shall not be punished twice for the same offense.
E.g., Illinois v. Vitale,
The two punishments imposed on Hatchett are based on two separate transactions — Hatchett’s distribution of crack cocaine to Riley, and Riley’s re-distribution of that cocaine to Panzer and Hess.
Blockburger v. United States,
Yet, as we shall see, Hatchett’s asserted liability as an aider and abetter of the second of these transactions — Riley’s distribution of the cocaine to Panzer and Hess — depends largely on proof that Hatchett supplied Riley with the cocaine. Consequently, the fact that there were two transactions in this case does not resolve the multiple-punishments question.
See Brown v. Ohio,
Dixon
informs us that in deciding •whether two offenses are the same or not, our inquiry must focus on the elements of each of the charged offenses rather than the underlying conduct.
Dixon
re-established the “same elements” test articulated by
Blockburger
as the one and only test that courts are to apply in considering -whether a defendant may be prosecuted or punished twice based on a single act or transaction.
Id.
at 703-12,
The applicable rule is that, where the same act or transaction constitutes a violation of two distinct statutory provisions, the test to be applied to determine whether there are two offenses or only one is whether each provision requires proof of an additional fact that the other does not.
The elements of the two crimes at issue here are, of course, distinct. In order to prove Hatchett guilty of distributing cocaine base in violation of 21 U.S.C. § 841(a)(1), the government was required to show that Hatchett distributed the crack cocaine to Riley, that he did so knowingly and intentionally, and that he knew he was distributing a controlled substance.
E.g., United States v. Clarke,
However, putting theoretical possibilities aside to focus on the facts of this case, it is clear that Hatchett could not have been convicted on the aiding and abetting charge in the absence of proof that he knowingly and intentionally distributed the cocaine to Riley. Hatchett did nothing to further Riley’s transaction with Panzer and Hess apart from supplying Riley with the cocaine. The government’s theory of the case was that Hatchett was not indifferent to the reasons for which Riley was purchasing the cocaine from him, and instead delivered the cocaine to Riley specifically for re-sale, with the understanding that Riley would pay him for the cocaine after Riley himself received payment from his customers. See R. 31 at 4, R. 81 at 37. Thus, although Count One of the indictment — Hatchett’s distribution to Riley— stood on its own, the aiding and abetting charge set forth in Count Two did not. Indeed, the government conceded at argument that even if Hatchett had been indicted only for aiding and abetting Riley’s sale, it still would have been required to prove that Hatchett delivered the cocaine to Riley.
Where proof of one offense necessarily entails proof that another offense occurred, rendering the latter a lesser included offense of the former, the two offenses are deemed to be the “same” for purposes of
Blockburger. See Rutledge,
*633 In a factual sense, one could view the distribution charge against Hatchett as a lesser included offense of the aiding and abetting charge. It was by supplying Riley with crack cocaine that Hatchett was said to have aided and abetted Riley’s distribution of the cocaine to Panzer and Hess. Consequently, in order to prove Hatchett guilty on the aiding and abetting charge, the government inevitably had to establish each of the elements necessary to convict Hatchett on the distribution charge. Obviously, it had to prove that Hatchett distributed a controlled substance to Riley, for without that delivery, Riley would have been unable to make the sale to Panzer and Hess. The government also had to show that the transfеr from Hatchett to Riley was knowing and intentional in order to prove that Hatchett knowingly assisted Riley’s distribution of the cocaine to his customers. For the same reason, the government was required to show that Hatchett realized he was delivering a controlled substance, for if Hatchett was ignorant of that fact, he could not have knowingly aided Riley’s redistribution of the cocaine.
However, there is one readily apparent respect in which the relationship between the two charges at issue in this case differs from the lesser-included-offense status that courts have cited in other cases. Distribution of a controlled substance obviously is not always a lesser included offense of aiding and abetting the distribution of a controlled substance. One can aid and abet a narcotics transaction in myriad ways other than by supplying the controlled substance.
Cf. Illinois v. Vitale, supra,
Precedent does make clear that one offense need not
invariably
be a lesser included offense of another in order for the two to be deemed the same-offense. In
Harris v. Oklahoma,
Three years later, in Vitale, the Court acknowledged the obvious implication of Hams — that one offense need not always constitute a lesser included offense of another in order to raise the double jeopardy bar, but that it may be recognized as such within the confines of an individual case.
*634 The Oklahoma felony-murder statute [at issue in Harris] on its face did not require proof of a robbery to establish felony murder; other felonies could underlie a felony-murder prosecution. But for the purposes of the Double Jeopardy Clause, we did not consider the crime generally described as felony murder as a separate offense distinct from its various elements. Rather, we treated a killing in the course of a robbery as itself a separate statutory offense, and the robbery as a species of lesser-included offense.
The Supreme Court’s more recent handling of
Dixon,
although it produced no majority opinion, confirms this point. In
Dixon,
the two respondents had been convicted of criminal contempt. One of the respondents, Dixon, by possessing cocaine with the intent to distribute, had violated a pre-trial release order issued in an unrelated сase that prohibited him from committing “any criminal offense,” and the other, Foster, by assaulting and threatening his estranged wife, had violated a civil protection order that required him not to “molest, assault, or in any manner threaten or physically abuse” her. Both were convicted of criminal contempt of court. The question presented to the Court was whether the contempt convictions prevented the government from later trying the men for the underlying acts of cocaine possession, assault, and threats to injure another. Most of the Court’s members agreed that
Grady v. Corbin
would bar the later prosecutions, as they implicated the same conduct on which the contempt convictions were based.
See
Justice Scalia’s opinion, joined in its lesser-included-offense analysis only by Justice Kennedy, reflected the judgment of the Court. Justice Scalia emphasized that the relationship between the criminal offenses under scrutiny cannot be assessed in the abstract, wholly divorced from the particular circumstances of the case:
We have described our tersé- per curiam opinion in Harris as standing for the *635 proposition that, for double jeopardy-purposes, “the crime generally described as felony murder” is not “a separate offense distinct from its various elements.” Illinois v. Vitale,447 U.S. 410 , 420-421,100 S.Ct. 2260 , 2267,65 L.Ed.2d 228 (1980). Accord, Whalen v. United States,445 U.S. 684 , 694,100 S.Ct. 1432 , 1439,63 L.Ed.2d 715 (1980). So too here, the “crime” of violating a condition of release cannot be abstracted from the “element” of the violated condition. The Dixon court order incorporated the entire criminal code in the samе manner as the Harris felony-murder statute incorporated the several enumerated felonies. Here, as in Harris, the underlying substantive criminal offense is “a species of lesser-included offense.” Vitale, supra,447 U.S., at 410 ,100 S.Ct., at 2267 . Accord, Whalen, supra.
In contrast to Justices Scalia and Kennedy, Chief Justice Rehnquist, joined by Justices O’Connor and Thomas, did not think that Harris’s lesser-included-offense analysis barred any of the later charges against Dixon and Foster. He did not quarrel with the notion that a conviction for a greater offense like felony murder would bar subsequent prosecution for any *636 of the myriad felonies that might have served as the predicate for the felony murder charge:
In Harris, we held that a conviction for felony murder based on a killing in the course of an armed robbery foreclosed a subsequent prosecution for robbery with a firearm. Though the felony-murder statute in Harris did not require proof of armed robbery, it did include as an element proof that the defendant was engaged in the commission of some felony. We construed this generic reference to some felony as incorporating the statutory elements of the various felonies upon which a felony-murder conviction could rest.
Id.
at 717,
Justice White, on the other hand, joined in relevant part by Justice Stevens, believed that the lesser-ineluded-offense analysis barred prosecution for
all
of the crimes for which Dixon and Foster were charged in the wake of their contempt convictions. Like Justice Scalia, Justice White believed that one had to look to the terms of the court orders that the respondents had been found to have violated in order to determine whether their contempt convictions necessarily entailed proof of the later-charged crimes.
See id.
at 731-32,
In sum, these three opinions reflect differences among the Supreme Court’s members as to how one should define the elements of the crimes under scrutiny for purposes of the lesser-included-offense analysis. Chief Justice Rehnquist and his contingent, as we have discussed, would look solely to the formal, statutory elements of the offenses to decide whether one offense required proof of another. Justices Scalia and White and them contingents, on the other hand, would look a bit further. Where, for example, the defendant has been convicted of contempt, as the respondents in Dixon were, they would look to the terms of the order that the defendant had disobeyed; and to the extent that order forbade the defendant from committing particular criminal acts, they would treat proof of such acts as an element of the contempt charge. However, although these three camps differed as to how one identifies the pertinent elemеnts of an offense for double jeopardy purposes, all agreed on one important premise: that an offense need not always be a lesser included offense of the other in order for the two to be treated as the “same” offense under Blockburger. If one offense, among many possibilities, serves in a particular case as the predicate for a greater offense like felony murder, then the defendant cannot be prosecuted or punished twice for both offenses, because the greater offense in that case necessarily requires proof of the lesser, and the two are in that sense one crime.
So, the fact that distributing a narcotic does not invariably constitute a lesser included offense of aiding and abetting does not foreclose the possibility that they could be considered the “same” offense for purposes of the double jeopardy analysis. Yet there remains one clear point of distinction that separates this case from both
Harris
and
Dixon.
In each of those cases, the greater offense demanded proof that another criminal offense had occurred. In
Harris,
the government had to prove that the defendant had committed a felony in order to prove him liable for felony murder. In
Dixon,
the court orders, either explicitly or implicitly, required the two respondents not to engage in criminal activity, so a conviction for criminal contempt required proof that they had committed one of the proscribed crimes. In each case, a variety of criminal acts might have sufficed as the predicate,
*638
but proof of some type of independent crime was necessary to establish the greater offense. Aiding and abetting, by contrast, does not demand, as one of its elements, proof that another crime occurred.
See
18 U.S.C. § 2; Federal Criminal Jury Instructions Of The Seventh Circuit, No. 5.06, at 78-79 (1999). One can aid and abet the commission of an offense without engaging in activity that amounts to a crime in and of itself.
See generally United States v. Irwin,
Prior to
Dixon, Vitale
would have been of some help to Hatchett on this point. In
Vitale,
a teenaged driver had struck and killed two children. A police officer cited him at the scene for failing to reduce his speed in order to avoid an accident, and he subsequently pleaded guilty to that charge. Subsequently, the State initiated a juvenile proceeding alleging that the driver had committed involuntary manslaughter. The Illinois Supreme Court held that the manslaughter charge was barred by the Double Jeopardy Clause, reasoning that the lesser offense (failure to reduce speed) required no proof beyond that which was necessary to establish that the juvenile had committed involuntary manslaughter and that, consequently, the two offenses were essentially the same. The U.S. Supreme Court agreed that “[i]f, as a matter of Illinois law, a careless failure to slow is
always
a necessary element of manslaughter by automobile, then the two offenses are the ‘same’ under
Blockburger
and Vi-tale’s trial would constitute double jeopardy under
Brown v. Ohio.”
[I]t may be that to sustain its manslaughter case the State may find it necessary to prove a failure to slow or to rely on conduct necessarily involving such failure; it may concede as much prior to trial. In that case, because Vitale has already been convicted for conduct that is a necessary element of *639 the more serious crime for which he has been charged, his claim of double jeopardy would be substantial under Brown [v. Ohio] and our later decision in Harris v. Oklahoma,433 U.S. 682 ,97 S.Ct. 2912 ,53 L.Ed.2d 1054 (1977).
Vitale
thus signaled the Court’s willingness to expand the lesser-included-offense analysis of
Harris
beyond the relatively limited category of cases in which one offense (felony murder being the obvious example) always requires proof that some other, lesser offense occurred. The Illinois involuntary manslaughter statute did not require proof that the defendant had committed another offense, it simply required proof that the defendant had recklessly engaged in an act that was likely to cause death or great bodily harm.
See
The scenario that Vitale envisioned is exactly the one we confront here. As we have explained, the aiding аnd abetting charge did not, on its face, demand proof that Hatchett distributed cocaine or that he engaged in any other act that was criminal in and of itself. But as it happens, the government could not prove him guilty of aiding and abetting Riley without also proving each and every element of the distribution charge.
But Vitale’s dictum has now been rejected, as the short life of Grady v. Corbin makes clear. Grady, as we mentioned earlier, embraced a double-jeopardy test that asked not only whether the two offenses in question had the same elements, but whether they rested on the same conduct. Grady, like Vitale, arose out of an automobile accident. The respondent, Corbin, had driven his automobile across the double yellow line of a highway and collided with two oncoming vehicles. The driver of one of those vehicles eventually died as a result of the collision, and her husband sustained serious injuries. Immediately after the accident, Corbin was cited for driving while intoxicated and for failing to keep to the right of the median. He pleaded guilty to those charges; and the sentencing judge, who was unaware that anyone had died as a result of the accident, suspended Corbin’s driver’s license for six months and imposed a modest fíne. A grand jury subsequently indicted Corbin on charges of, inter alia, reckless manslaughter and criminally negligent homicide in connection with the death of the one accident victim, and reckless assault in connection with the injuries to the other. The prosecution filed a bill of particulars identifying three acts on which it would rely to establish that Cor-bin had operated his automobile in a negligent or reckless fashion: (1) driving while intoxicated; (2) failing to keep to the right of the median, and (3) driving at a rate of speed that was excessive given the weather and road conditions.
Taking its cue from
Vitale,
the Supreme Court concluded that double jeopardy principles prevented the prosecution of Corbin on the new charges. “As we suggested in
Vitale,
the Double Jeopardy Clause bars any subsequent prosecution in which the government, to establish an es-r sential element of an offense charged in that prosecution, will prove conduct that constitutes an offense for which the defendant has already been prosecuted.”
By its own pleadings, the State has admitted that it will prove the entirety of the conduct for which Corbin was convicted — driving while intoxicated and failing to keep right of the median — to establish essential elements of the homicide and assault offenses. Therefore, the Double Jeopardy Clause bars this successive prosecution....
Ibid.
In all material respects, the instant case is indistinguishable from Grady. 5 The government has conceded that in order to prove Hatchett guilty of abetting and abetting Riley’s distribution of cocaine to Panzer and Hess, it necessarily had to establish that Hatchett supplied the cocaine to Riley. That concession, like the bill of particulars in Gmdy, leaves no doubt that conviction on the second, greater charge depends on proof of conduct that constitutes the first, lesser offense. If Grady remained good law, then, we would deem the distribution charge and the aiding and abetting charge to be a single offense for which (absent a congressional signal to the contrary) only one punishment could be imposеd.
But
Grady,
after all, has been overruled. The Supreme Court in
Dixon
unequivocally rejected
Grady’s
“same conduct” test,
see
We note that the First Circuit, in a similar case that also post-dates
Dixon,
has reached the same conclusion that we do today.
See United States v. Colon-Osorio,
Indeed, the district court’s analysis is precisely what the Dixon Court rejected. Under Dixon, the fact that the government will attempt to prove that Colon-Osorio was a fugitive by referring to the same conduct used to prove the elements of failure to appear does not offend the Double Jeopardy Clause. The same actions can constitute an offense under two distinct statutes and can be prosecuted separately under each statute as long as the statutes do not define a single offense within the meaning of Blockburger. United States v. White,1 F.3d 13 , 17 (D.C.Cir.1993); see also Blockburger,284 U.S. at 304 ,52 S.Ct. at 182 (quoting Morey v. Commonwealth,108 Mass. 433 (1871)).
For all of these reasons, we conclude that the offenses charged in Counts One and Two of the indictment did not constitute a single offense within the Blockburger framework. The two charges were distinct in the sense that each required proof of an element that the other did not. Moreover, although, under the circumstances of this particular case, the aiding and abetting charge required proof of the very same conduct which underlay the distribution charge, the aiding and abetting charge did not demand proof that Hatchett had committed any other crime, be it narcotics distribution or something else. Consequently, in light of Dixon, the distribution charge cannot be described as a lesser included offense of the aiding and abetting charge.
B.
Hatchett contends that the district court abused its discretion in permitting Robert Panzer to testify that he had purchased crack cocaine from Hatchett (through Riley) one month before the transaction with which he was charged in this case. As we have noted, the court deemed this testimony admissible pursuant to Rule 404(b), which grants the district court discretion to admit evidence of a defendant’s “other crimes, wrongs, or acts” in order to establish something other than the defendant’s propensity to engage in criminal conduct.
See generally United States v. Wash,
We are satisfied that testimony concerning the October transaction was admissible to establish Hatchett’s knowledge, if nothing else. In discussing Hatchett’s double jeopardy claim, we pointed out that in order to prove Hatchett guilty of distributing cocaine to Riley, the government was obliged to prove that Hatchett knowingly and intentionally distributed the narcotic to Riley and that he knew cocaine was a
*643
controlled substance. Similarly, in order to prove that Hatchett aided and abetted Riley, the government was required to show, inter alia, that Hatchett knowingly associated himself with Riley’s delivery of the cocaine to Panzer and Hess.
Ante
at 631. Hatchett’s awareness of the illicit nature of the business that Riley was transacting with Panzer and Hess on November 24 was thus a key element of the prosecution’s case. Although Hatchett insists that his knowledge was actually not in issue, because he simply argued that he did not supply Riley with the cocaine (Blue Br. at 27), the record belies his contention. In fact, Hatchett specifically denied having any knowledge that Riley was distributing cocaine to Panzer and Hess. R. 70 at 11-12, 14. Under these circumstances, we believe that testimony concerning the October transaction—which involved both Riley and Panzer’s brother—was admissible to prove that Hatchett was not merely an unwitting bystander to the distribution of crack cocaine, but a knowing participant.
See United States v. Mounts,
We are also satisfied that Panzer’s testimony concerning the October transaction was sufficiently reliable to qualify for admission under Rule 404(b).
See Huddleston v. United States,
Consequently, we find no abuse of discretion in the district court’s decision to admit Robert Panzer’s testimony. The testimony was probative of Hatchett’s knowledge as to the nature of the November 24 transaction. Moreover, the district сourt appropriately instructed the jury as to the limited purposes for which it might consider this evidence. That cautionary instruction adequately addressed the concern that the jury might improperly infer from the testimony a propensity on Hatchett’s part to engage in narcotics transactions.
See Williams,
C.
At the close of the defense case, Hatchett offered into evidence a laboratory report prepared by the Wisconsin Crime Laboratory which indicated that a fingerprint located on a metal cigar box in which Hatchett had delivered the crack cocaine to Riley could not be identified as belonging to either Hatchett or Riley. Hatchett contended principally that the report was admissible as a public record pursuant to *644 Fed.R.Evid. 803(8). 6 Absent a stipulation between the parties as to the authenticity of the lab report, the district court declined to admit the report into evidence without appropriate testimony from a foundation witness. R. 80 at 270-71. Although the defense had already rested, the court indicated that it was prepared to allow Hatchett to re-open his case in ordеr to supply that testimony. “If that’s what you want to do,” Judge Shabaz remarked, “I’ll give you that opportunity.” Id. at 271. Hatchett’s counsel declined the court’s offer, however:
In all candor, Your Honor, I did not subpoena Mr. Heslip [the laboratory analyst] nor will I ask the Court to reopen evidence. This was my attempt to offer this document in this format and that was my choice, so I will live with the Court’s ruling.
Id.
Hatchett contends that the laboratory report was admissible pursuant to Rule 803(8)(C), which provides that official investigative findings are admissible “against the Government in criminal cases,” unless there is reason to doubt their reliability.
See
n. 6,
supra.
In passing, the district judge expressed doubt whether subsection (C) applied, because “this isn’t a matter against the government.” R. 80 at 271. In this respect the judge misread the rule, which requires only that the report be offered against the government, not that the proceeding be one against the government,
e.g., United States v. King,
At most, however, the district court’s construction of Rule 803(8)(C) amounted to an alternative ground for excluding the report. The principal reason why the court did not admit the repоrt, and the one it cited both first and last in its ruling, was the lack of a witness who could identify and authenticate the report.
See
R. 80 at 270-71. Read in their entirety, the district court’s remarks leave no doubt that, irrespective of its understanding as to the scope of Rule 803(8)(C), the court would not have allowed the lab report into evidence without foundation testimony from an appropriate witness.
See United States v. Romo,
Hatchett has not addressed the district court’s observations with respect to the need for a foundation witness.

“[I]n situations in which there is one or more alternative holdings on an issue, we have stated that failure to address one of the holdings results in a waiver of any claim of error with respect to the court’s decision on that
