OPINION
The principal issue in this appeal is whether the district court’s permitting a police officer to testify as both an expert and a fact witness, without the court’s issuing a cautionary instruction to the jury, constitutes reversible error, pursuant to
United States v. Lopez-Medina,
I.
David Martin was a crack dealer in Louisville, Kentucky. The police set up two controlled buys during which a confidential informant purchased 1.5 and 1.39 grams of crack, respectively. The police obtained a warrant to search Martin’s residence, an apartment leased to one Susan Tyson. During the search, the police found and seized 5.16 grams of crack cocaine, drug paraphernalia, a 9 mm hand *658 gun with ammunition, some .357 caliber ammunition, and a phone bill addressed to Martin at that address. When the police later attempted to arrest Martin, he fled on foot but was quickly apprehended. The police found 3.21 grams of crack cocaine in his possession.
A federal grand jury indicted Martin on seven counts: two counts of distributing crack cocaine; one count of being a felon in possession of a handgun; two counts of possessing crack cocaine with the intent to distribute; one count of possessing a handgun in furtherance of drug trafficking; and criminal forfeiture of $870 in currency and a 9 mm handgun seized from the apartment. The case went to trial and a jury convicted Martin on five counts, but acquitted him on the gun-in-furtherance-of-trafficking charge. The court convicted him on the forfeiture charge when Martin chose not to oppose it. Martin now appeals.
II.
A.
Martin argues that the district court erred by allowing a police officer to testify as both an expert in drug trafficking and as a fact witness, because the court did not draw a clear line of demarcation between the two types of testimony or issue a cautionary instruction to the jury about the difference between expert and fact testimony. Martin neither raised any objection in the district court nor requested any cautionary instruction.
An appellant who fails to object in the district court forfeits the right to protest the error on appeal and we review the claim for plain error.
See
Fed.R.Crim.P. 52(b). Under the plain error standard, we may reverse if (1) there was error that (2) was plain, (3) affected a substantial right, and (4) “seriously affects the fairness, integrity, or public reputation of judicial proceedings.”
United States v. Oliver,
In
United States v. Lopez-Medina,
Because there was no cautionary jury instruction regarding the [DEA] agents’ dual witness roles nor a clear demarcation between their fact testimony and *659 expert opinion testimony, we conclude that the district court committed an error that was plain or obvious in permitting the dual-role testimony.
Id. at 745. Having found the first two requirements for plain-error, we turned to the third:
[W]e conclude that the district court’s error in its jury instruction, in conjunction with the other evidentiary errors we find occurred in Medina’s trial, may have affected the outcome of his trial and therefore warrants a reversal of his conviction. Thus, Medina can establish an effect on his substantial rights.
Id. And, the fourth requirement:
We conclude that permitting [these DEA agents] to testify as experts in their own investigations and give opinion testimony on the significance of evidence they have collected, absent any cautionary instruction, threatens the fairness, integrity, and public reputation of judicial proceedings, regardless of whether the defendant is actually innocent.
Id. Thus, we found reversible error and vacated Lopez-Medina’s conviction. Id. at 752.
We examine the present case in light of
Lopez-Medina,
mindful that “plain error depends on the facts of the particular case,”
Clark,
Martin’s counsel did not object to any of this testimony because of its expert character, or ask for a cautionary jury instruction, and the court did not give any such instruction. After carefully reviewing the testimony, we conclude that the fact and expert testimony here is not nearly so thoroughly intertwined as it was in
Lopez-Medina,
but neither is the line of demarcation between the two indisputably clear. But, even assuming we were to conclude that the demarcation is insufficient and this situation involves “an error that was plain or obvious in permitting the dual-role testimony,”
Lopez-Medina,
*660
Looking at this claim of plain error in the context of the particular facts of this case, the dual testimony here is insufficient to “show [ ] an actual effect on the outcome of the case.”
Id.
(citing
United States v. Jones,
Nor can we conclude in this particular case that this dual testimony seriously affected the fairness, integrity, or public reputation of the proceedings. Quite to the contrary, as the Supreme Court exclaimed in
Johnson,
Martin’s argument lacks merit. The district court did not commit plain error by allowing the police officer to testify as both expert and fact witness without a cautionary instruction.
B.
Martin argues that the evidence was insufficient to support a conviction. “In determining the sufficiency of the evidence to support a guilty verdict ‘the relevant question is whether, after viewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.’ ”
United States v. Pearce,
On the distribution charge, the government produced two police officers who testified to witnessing the drug transactions and identified Martin in court. Martin argues that this is insufficient, inasmuch as the government did not produce any marked currency, photo or video evidence of the crime, audio recordings of the crime, or confidential informant testimony. But clearly, a reasonable juror could have believed the officers, so we cannot overturn the jury’s verdict.
On the gun possession charge, the government produced evidence that the gun was found beside the bed in the master bedroom of Ms. Tyson’s apartment, and that a quantity of men’s clothing was found in the closet in that bedroom; further, the government produced evidence-— including a telephone bill to Martin at that *661 address as well as a prescription drug container bearing Martin’s name, which was in the medicine cupboard in the apartment—that Martin was residing there. Martin argues that Susan Tyson testified to owning the gun and decries the lack of fingerprint evidence to demonstrate his ownership. But again, a reasonable juror could have drawn the inference that Martin possessed the gun, and therefore we cannot overturn the jury’s verdict.
Martin’s challenge to the sufficiency of the evidence is without merit.
C.
Martin makes several allegations regarding the prosecutor’s closing argument, some of which were the subject of objections'at trial, and others of which are not. The objections which he raised at trial we review under the traditional prosecutorial misconduct standard. The others we review for plain error.
First, Martin argues that the government’s closing argument, which he claims referred to evidence not admitted and misstated that evidence, was inflammatory and designed to arouse the jury’s emotion and prejudice. The evidence in question is a self-incriminating rap song, written by Martin, which the police found in a notebook recovered from his residence. Despite Martin’s claim to the contrary, this was entered into evidence, and—as Martin explains'—the prosecutor read this song to the jury at the beginning of the rebuttal argument. In short, it was relevant to rebut defense counsel’s argument that the guns were not Martin’s and were not used in drug dealing (an argument the jury appears to have believed, inasmuch as it acquitted Martin on the gun-used-in-trafficking charge). This was not a misrepresentation of any evidence nor was it inherently inflammatory.
Next, Martin claims that the prosecutor denigrated defense counsel by stating that the police do not need to produce every type of evidence that the defense lawyer can “think up,” referring specifically to fingerprints on the gun. Again, this was a rebuttal argument—specifically, rebuttal to defense counsel’s argument that (despite the eye witnesses) the prosecutor had not satisfied the government’s burden of proof beyond a reasonable doubt because it had not produced numerous other types of evidence, such as videos, audiotapes, fingerprints, etc. There is no basis to conclude from this exchange that the prosecutor denigrated defense counsel.
Finally, Martin contends that the prosecutor violated his right to a fair trial by calling him a drug dealer and urging the jury to convict him. Martin cites
United States v. Solivan,
Martin’s claim of prosecutorial misconduct is without merit.
D.
Martin contends—as best as we can tell from the vague discussion in his brief— *662 that the court erred by finding him to be a career offender and thereby calculating a higher advisory sentence range than it would have calculated if it had not found him to be a career offender. But, Martin’s counsel conceded at sentencing that Martin is a career offender, and rather than protesting that finding, argued instead for a departure below the guidelines range.
This argument has no merit. The district court committed no error and we have no basis to conclude that the district court sentenced Martin unreasonably or abused its discretion in doing so.
III.
For the foregoing reasons, we AFFIRM the judgment of the district court.
