Opinion for the Court filed by Circuit Judge HENDERSON.
Alvaro Augustin Mejia and four co-defendants were charged with a single count of conspiring to import five or more kilograms of cocaine into the United States after a United States Drug Enforcement Administration (DEA) sting operation caught them on tape plotting to transport and safeguard a 1,300 kilogram drug shipment through Guatemala. On appeal, Mejia challenges various aspects of his conviction and sentence. We affirm.
I.
In late 2005, the DEA initiated a Central American sting operation that ensnared Mejia and four fellow Guatemalan coconspirators: Jorge Ricardo Bardales-Bourdet (Bardales), Edgar Antonio Chiu Serrano (Serrano), Erik Donaire Constanza-Bran (Bran) and Juan Daniel Del Cid Morales (Morales). According to the evidence at trial, the DEA learned that Bar-dales was helping Colombian drug traffickers move cocaine through Guatemala with the help of corrupt Guatemalan law enforcement officials. In response, the DEA enlisted a pseudonymous confidential informant, “Augustine Cortez,” to pose as a cocaine supplier and meet with Bardales. At their first meeting (also attended by Serrano, who was introduced as a Guatemalan law-enforcement officer), Cortez asked Bardales to arrange for security to transport a container of cocaine through Guatemala en route to the United States. Bardales agreed and proposed to charge Cortez one million dollars to move 3,000 kilograms. (Cortez surreptitiously recorded this and all subsequent meetings and telephone calls, transcripts of which were introduced by the government and described by Cortez at trial.)
In the weeks that followed the initial contact, Bran, who was Serrano’s boss, followed up with Cortez numerous times to set up a meeting at which Bran planned to introduce Cortez to two Guatemalan law enforcement officials who would provide protection for the cocaine shipments: Me *1333 jia and the fourth eodefendant, Morales. Meeting at a restaurant in San Salvador, El Salvador in July 2006, the informant Cortez told the four men assembled (Bar-dales, Bran, Morales and Mejia) that he intended to transport 1,300 “units” through their country. Meeting Tr., July 19, 2006 at 20. Bardales assured Cortez that Morales and Mejia would take care of transportation and security. See id. at 13 (identifying Morales and Mejia as “the ones in charge of everything that has to be done”). Although Mejia spoke little, he presented false identification and posed as “Edwin Rene Sapon-Ruiz,” a high-level Guatemalan official with customs oversight authority. (Mejia was in fact a retired Guatemalan police officer.) Mejia said that Guatemalan law enforcement was “creat[ing] a new unit, DIPA [División de Protección de Puertos y Aeropuertos],” to handle narcotics and to “work[ ] ports and airports.” Trial Tr., Feb. 27, 2008 (P.M.) at 61-62. Mejia suggested that he and Morales might be able to “control the commanders, the people who control[ ] DIPA.” Id. at 62-63. At the end of the meeting, Cortez paid Morales $10,000 in advance.
Cortez met again with Bran, Morales and Mejia at the same restaurant in August 2006. (Bardales, who had been seriously injured in an automobile accident shortly before the meeting, did not attend.) According to Cortez, Bran had paperwork involving a “cover-up company” Bran controlled, and which could be used to stash the cocaine amidst legitimate cargo — specifically, Christmas decorations. 1 Trial Tr., Feb. 28, 2008 (A.M.) at 11. Bran explained to Cortez how to ship the drugs to prevent detection. Again, Mejia said little.
The group met for a third and final time in September 2006. A few minutes into the meeting, Salvadoran police officers arrested all three men. Lead DEA Agent Stephen Fraga, who did not witness the arrest, arrived at the scene about ten minutes later. He testified that: one of the Salvadoran policemen handed him a bag of seized evidence for each of the arrested men and each bag contained a wallet; Mejia’s wallet contained a folded piece of paper with a handwritten list of names and the word “DEA” handwritten on the side; both Mejia’s and Morales’s wallets contained semiautomatic handgun permits; and two handguns were seized from Bran’s driver, who was not charged as a co-conspirator.
Mejia, Morales and Bran were handed over to DEA Agents Fraga and Jason Sandoval about ninety minutes after the arrest and were promptly taken aboard a DEA airplane bound for the United States. During the flight, Mejia signed a written waiver of rights and spoke to the DEA agents, who took notes but did not record the interview. According to the agents’ testimony, Mejia confessed that he and Morales had been asked by Bran “to act as police officers ... to facilitate a cocaine transaction [by Cortez, who] ... obtained a container filled with cocaine in Colombia and was seeking protection for that cocaine once it arrived in Guatemala”; “he specifically represented himself as a different police officer to make money”; he “was aware that the container was to contain cocaine ... [and] was destined for the United States”; “he was knowledgeable of the topic of the stolen cocaine, and the prices of the stolen cocaine”; and “he had given thought to stealing the cocaine and reselling the cocaine in Guatemala for $4500 per kilogram.” Trial Tr., Mar. 3, 2008 (P.M.) at 9-10, 97-101.
On September 20, 2007, Mejia and his four co-defendants were charged in a one- *1334 count superseding indictment with conspiring to import five or more kilograms of cocaine into the United States in violation of 21 U.S.C. §§ 952, 959, 960 and 963. Mejia, Morales and Bran all pleaded not guilty and the district court severed their cases for separate trials. (Serrano remains at large and Bardales eventually died from his auto accident injuries.) After Bran’s trial resulted in a hung jury, he pleaded guilty and was sentenced to 144 months’ imprisonment. In February 2008, shortly before Mejia’s trial, the government offered Morales and him a wired Rule 11(c)(1)(C) nine-year plea agreement, which they rejected. Morales was convicted by a jury and sentenced to 220 months’ imprisonment. 2 On March 8, 2008, after an eight-day trial, Mejia was also convicted. Because the conspiracy involved more than 150 kilograms of cocaine, Mejia’s offense level was calculated at 38. Combined with his criminal history category of I, the advisory range of imprisonment was 235 to 293 months under the United States Sentencing Guidelines (Guidelines). See U.S.S.G. Ch. 5, Pt. A (sentencing table). The government recommended a below-Guidelines sentence of 210 months. Mejia asked for 60 months (one-half the 120-month statutory mandatory minimum), seeking an adjustment for his minor role in the offense, see U.S.S.G. § 3B1.2, as well as various discretionary departures, see id. § 5H1.4 (physical condition), id. § 5H1.5 (employment record), id. § 5H1.6 (family responsibilities), id. § 5H1.11 (military, civic, charitable and public service, employment-related contributions and record of good works), and id. § 5K2.20 (aberrant behavior). The district court found Mejia’s account of the facts implausible 3 and declined to adjust his sentence based on his purportedly minor role; it then sentenced Mejia to 208 months’ imprisonment. Mejia’s sentence — slightly over seventeen years — was nearly twice as long as the sentence proposed in the Rule 11(c)(1)(C) plea offer he rejected but more than two years fewer than the advisory range of 235 to 293 months.
II.
Mejia now appeals, asking the court to vacate his conviction or, in the alternative, to remand for resentencing. He contends that the court made a series of errors that, alone or together, entitle him to a new trial and sentence. His objections fall within four categories that we address in turn: the court’s admissibility rulings, its jury instructions, the government’s closing argument and the sentence imposed.
A.
Mejia contends that the district court erred in admitting various items and testimony into evidence. We review admissibility rulings for abuse of discretion.
See United States v. Coumaris,
*1335
The “DEA Note.”
We begin with Mejia’s chain-of-custody objection. Citing
Novak v. District of Columbia,
The handwritten note with “DEA” and several names on it was admitted despite an undisputed break in the chain of custody. As noted earlier, shortly after Mejia (along with Morales, Bran and the informant Cortez) arrived at his third and final meeting, several Salvadoran police officers entered the restaurant where the three co-conspirators and Cortez were meeting and arrested them. DEA Agent Fraga did not witness the arrest because at the time he was in an automobile parked several blocks away from the scene. He testified that he arrived at the restaurant about ten minutes after the arrest, at which point he was given a bag from a Salvadoran police officer he presumed to be the leader of the arrest team. The bag contained Mejia’s personal effects. The Salvadoran officer who seized Mejia’s belongings did not testify and the government did not identify him; in fact, the government did not call any witness who took part in Mejia’s arrest and the seizure of his property. Neither did it introduce a return or other official document listing the items seized from Mejia upon arrest. Agent Fraga testified that among the items included in the bag the Salvadoran officer gave him was Mejia’s wallet and inside the wallet he found a folded, handwritten note with “DEA” and a list of names on it. The names included at least five agents stationed in the DEA’s Guatemala City office. The paper did not include Mejia’s name or signature and no handwriting or fingerprint evidence was introduced to link Mejia to it. In short, Mejia’s chain-of-custody objection to the admission of the list — that it was given to Agent Fraga by “[sjomeone who’s not present here and we don’t know what happened to it [before Agent Fraga obtained it],” Trial Tr., Mar. 3, 2008 (P.M.) at 102 — is fundamentally correct.
But was it nevertheless admissible? “It is generally recognized that tangible objects become admissible in evidence only when proof of their original acquisition and subsequent custody forges their connection with the accused and the criminal offense.”
Gass v. United States,
We have since retreated somewhat from
Novak,
holding that a challenge to the chain of custody goes to weight rather than admissibility.
See United States v. Stewart,
But
Stewart
involved circumstances in which there was in fact no break in the chain of custody.
See Stewart,
*1337
The government asserts that the district court did not err because it was entitled to presume the “integrity of evidence routinely handled by government officials” and, although this presumption may be rebutted with a “minimal showing of ill will, bad faith, other evil motivation, or some evidence of tampering,” Mejia made no such showing here.
Lane,
On the one hand, the defect here was different from the ones in
Lane
and
Stewart
— both of which involved an unbroken chain of custody but either an unexplained delay,
see Stewart,
We conclude that the district court did not abuse its discretion in admitting the list. Even if admitting the list was error, however, it was harmless in light of its limited importance and the strength of the other evidence against Mejia.
See
*1338
Kotteakos v. United States,
The Firearm Permit Evidence.
The district court admitted over Mejia’s objection a firearm permit found in Mejia’s wallet as well as testimony that the police also seized a firearm permit from Morales and two handguns from Bran’s driver. The government is correct that “this circuit has frequently recognized that guns and drugs go together in drug trafficking,”
United States v. McLendon,
But the probative value of a firearm permit possessed by a former police officer seems to us to be nil. Likewise, the probative value of testimony as to firearms carried by Bran’s driver — who was not charged as a member of the conspiracy— also seems negligible. In spite of the limited probative value, we need not decide whether the district court “grave[ly]” abused its discretion in admitting this evidence over Mejia’s Rule 403 objection, see
United States v. Douglas,
Other Evidentiary Rulings.
We quickly dispense with Mejia’s other assertions of error in evidentiary rulings. First, he maintains that the government erroneously failed to correct the false denial of its main witness, Cortez. This contention (which we review
de novo, see United States v. O’Keefe,
Although the government “may not knowingly use ... false testimony! ] to obtain a tainted conviction,” including testimony that goes to the credibility of a witness,
see Napue v. Illinois,
Citing
Whitmore,
Finally, Mejia complains that the district court erred in qualifying Carrillo Garcia, a Guatemalan police officer with fourteen years’ experience, as an expert in drug trafficking because none of the cases Garcia participated in was prosecuted in the United States. But Garcia was not qualified as an expert in cocaine importation or prosecution in the United States but rather “in the field of drug-trafficking and transportation activities as they relate to Guatemala.”
See
Trial Tr., Feb. 29, 2008 (P.M.) at 45-46. Moreover, Garcia had, in fact, testified in at least two U.S. prosecutions.
See
Trial Tr., Feb. 29, 2008 (P.M.) at 35 (Garcia testified a dozen times or more in Guatemala and twice in the United States). Accordingly, Mejia has not shown that the district court erred in qualifying Garcia as an expert.
See Haarhuis v. Kunnan Enters., Ltd.,
*1340 B.
Mejia next objects that the trial court improperly instructed the jury in two respects. Our review is
de novo. See United States v. Orenuga,
Mejia acknowledges that
Taylor
“affirmed a conviction involving the same instruction at issue here,” Appellant’s Br. at 14, but attempts to distinguish it in several ways. For example, he asks us to attach significance to the fact that, unlike Taylor, who had unsuccessfully requested an alternative “reasonable doubt” instruction, Mejia requested that no charge be given. We decline to do so. “[T]he Constitution neither prohibits trial courts from defining reasonable doubt nor requires them to do so as a matter of course,”
Victor v. Nebraska,
Additionally, Mejia contends that the district court deprived him of due process of law when it instructed the jury: “You may infer but are not required to infer that a person intends the natural and probable consequences of acts knowingly done or knowingly omitted.” Trial Tr., Mar. 5, 2008 (P.M.) at 48. The Supreme Court has distinguished between language that creates a “mandatory presumption” and language that allows a permissive inference.
See Frauds v. Franklin,
C.
Mejia contends that the government’s closing argument included several statements unsupported by the evidence. Specifically, he objects to the government’s contentions that (1) the co-conspirators needed Mejia because of his police connections (even though another conspirator, Morales, was also a retired Guatemalan police officer); (2) Mejia lived in Guatemala City at the time of the conspiracy (when the only record evidence was that he had lived there five or six years earlier); (3) Guatemalan police were essentially powerless to stop the gangs because Guatemala was emerging from a bloody civil war (based on a lack of record evidence regarding the civil war); and (4) DIPA was the Guatemalan “customs anti-narcotics agency” and Mejia was willing to use his connections there (based on a lack of supporting evidence).
A prosecutor errs in closing argument by making a statement unsupported by evidence, misstating evidence or misquoting testimony.
See United States v. Watson,
Second, the only record evidence regarding Mejia’s residence was the testimony of the sole defense witness, Francisco De Leon, that Mejia had lived in Guatemala City five or six years earlier, but “no longer lives there now.” Trial Tr., Mar. 5, 2008 (A.M.) at 36. Considering that Mejia was in federal custody at the time of the witness’s testimony, this statement is ambiguous and hardly stands for the proposition that Mejia was no longer a Guatemala City resident when arrested. 8 Third, the prosecutor’s argument was not, contrary to Mejia’s objection, about the relationship between Mejia and the Guatemalan civil war but instead about the powerlessness of the Guatemalan police, of which there was plenty of record evidence. See, e.g., Trial Tr., Feb. 29, 2008 (A.M.) at 88 (“Guatemala has a very fragile law enforcement system, and it’s very easy to bring large quantities of drugs into Guatemala without really worrying about being caught.”). Last, we disagree with Mejia’s complaints as to the lack of evidence that DIPA was an anti-drug agency and that Mejia was willing to use police connections, as the record sufficiently supports both claims. See Trial Tr., Feb. 29, 2008 (P.M.) at 21 (DIPA’s “main purpose ... was to attack the narcotic activity at” Guatemala’s seaports); see Meeting Tr., July 19, 2006 at 16 (Mejia’s videotaped statements that DIPA’s “commands are ours,” and “[w]hat we have to control is the structure” of DIPA).
Mejia also challenges the prosecutor’s embellishment in closing: “[W]e forget that the success of a drug trafficker is based upon a human weakness called addiction” and that drug dealers “make a lot of money by preying on that human weakness.” Trial Tr., Mar. 5, 2008 (A.M.) at 71. We have held that a more detailed comment was improper.
See United States v. Johnson,
*1343 D.
Finally, Mejia challenges his sentence on multiple grounds. We review the district court’s sentence for abuse of discretion, first ensuring that the court committed no significant procedural error and then ascertaining if the sentence is substantively reasonable.
See Gall v. United States, 552
U.S. 38, 51,
Contrary to Mejia’s first argument, his sentence is consistent with
Apprendi v. New Jersey,
Second, we do not agree that Mejia’s sentence was unreasonable based on the district court’s failure to grant a number of the adjustments and departures Mejia requested — including, most significantly, a multi-level adjustment for his allegedly minor role in the offense.
See
U.S.S.G. § 3B1.2. Although the district judge (who also presided over the trials of Bran and Morales) determined that “Mejia’s role was the least of the three,” he permissibly and reasonably concluded that no one in the conspiracy played a “minor” role. Sentencing Tr., Oct. 16, 2008 (A.M.) at 56-57, 70 (finding Mejia “was aware of the full plan,” took “three trips to El Salvador for purposes of meetings to further this conspiracy” and “was to have the important role of a security function”). As for the discretionary departures, because the judge plainly recognized his authority to impose a below-Guidelines sentence — he gave one, after all — his decision was in accord with
United States v. Booker.
Insofar as Mejia contends that his sentence was substantively unreasonable,
see Gall, 552
U.S. at 51,
Third, Mejia argues that his sentence resulted in an unwarranted disparity between himself and co-defendant Bran, in *1344 contravention of a statutory sentencing factor. See 18 U.S.C. § 3553(a)(6) (sentencing court must take account of “need to avoid unwarranted sentence disparities among defendants with similar records who have been found guilty of similar conduct”). It is true that Bran, who — the court determined — had played a leadership role in the conspiracy, received only 144 months, a sentence more than five years shorter than Mejia’s 208-month sentence. See Sentencing Tr., Oct. 16, 2008 (A.M.) at 69-70 (“Mr. Bran was more of the leader than these two were.”). But Morales — the third co-defendant, who, according to the district court, played a role closer to Mejia’s than Bran’s — was sentenced to 220 months, one year longer than Mejia.
We conclude that there was no error in the disparity between Mejia and Bran, which disparity is entirely explained by Bran’s three-level acceptance-of-responsibility reduction for his having pleaded guilty after his jury hung, which lowered his advisory Guidelines range to 168-210 months.
See
U.S.S.G. § 3E1.1 (defendant who “clearly demonstrates acceptance of responsibility for his offense” is entitled to reduction);
see, e.g., In re Sealed Case,
Fourth, we reject Mejia’s claim of prosecutorial vindictiveness. His claim is premised on the fact that the sentence the government recommended following trial was nearly twice the length of the plea offer he rejected before trial. But there is nothing impermissible (or even unusual) with the prosecutor recommending a longer sentence after trial than before trial. Nor, as noted, is there anything out of the ordinary with the defendant’s acceptance of responsibility factoring into the sentencing calculus.
See
U.S.S.G. § 3E1.1;
United States v. Jones,
III.
For the foregoing reasons, Mejia’s conviction and sentence are affirmed.
So ordered.
Notes
. And thus giving unintended meaning to a "white Christmas.”
. Both Bran and Morales appealed to this Court. We affirmed Bran's conviction and sentence on October 29, 2009.
See United States v. Constanza Bran,
No. 08-3086,
. The court found:
It is not plausible that he went to three meetings in another country and believed that this only involved moving Christmas goods for possible avoidance of Customs or tax requirements ... [as that] does not comport with the evidence at trial and is not in my view what an experienced police officer could possibly have believed in light of the circumstances that he was involved in and the discussions that were taking place.
Sentencing Tr., Oct 16, 2008 (A.M.) at 59.
. The United States Supreme Court made the
same
point last year.
See Melendez-Diaz v.
*1336
Massachusetts,-U.S.-,
. Mejia also challenges the admissibility of Agent Fraga’s notes of his interview with Mejia, which notes were discussed during his cross-examination and on redirect. But Agent Fraga’s notes were not admitted into evidence.
. Over Mejia's objection, the court defined "reasonable doubt" as follows:
Proof beyond a reasonable doubt is proof that leaves you firmly convinced of the Defendant's guilt. There are very few things in this world that we know with absolute certainty, and in criminal cases, the law does not require proof that overcomes every possible doubt.
If, based on your consideration of the evidence you are firmly convinced that the Defendant is guilty of the crime charged, you must find him guilty. If, on the other hand, you think there is a real possibility that the Defendant is not guilty, you must give him the benefit of the doubt and find him not guilty.
Trial Tr., Mar. 5, 2008 (P.M.) at 32. The instruction is taken verbatim from the Federal Judicial Center’s Pattern Criminal Jury Instruction 21 (Federal Judicial Ctr.1988), which has been described as "clear, straightforward, and accurate.”
Victor v. Nebraska,
. We have also upheld an instruction containing similar language in a case involving a specific intent crime.
See United States v. Moore,
. Indeed, even on appeal, Mejia does not assert that the statement was wrong, simply that ''[tjhere also was no evidence in the record that Mejia lived in Guatemala City during the time of the offense.” Appellant's Br. at 25.
