Defendant Robert Hertular appeals from a judgment of conviction entered on April 4, 2007, by Judge Naomi Reice Buchwald after a jury trial in the United States District Court for the Southern District of New York. Hertular stands convicted of four crimes: (1) conspiracy to import five kilograms or more of cocaine, see 21 U.S.C. §§ 952(a), 963; (2) distribution of five kilograms or more of cocaine, knowing that it would be imported into the United States, see id. §§ 959(a), 960(b)(l)(B)(ii); (3) forcibly impeding or intimidating a federal officer, see 18 U.S.C. § 111; and (4) obstruction of justice, see id. § 1512(b)(3). He is presently incarcerated serving a non-Guidelines prison term of 400 months (33-1/3 years). Through counsel, Hertular challenges his conviction on the grounds that (1) the trial evidence was insufficient to support the jury’s guilty verdicts on the counts of (a) forcibly impeding or intimidating a federal officer and (b) obstructing justice; (2) the district court erroneously instructed the jury on the elements of obstruction of justice; and (3) the 400-month sentence is infected by procedural error and, in any event, is substantively unreasonable. In a pro se submission, Hertular raises myriad other challenges.
Because we conclude that the trial evidence, even when viewed in the light most favorable to the government, was insufficient to support a guilty verdict under the § 111 count (Count Three), we are obliged to reverse the conviction on that count and to vacate the sentence and to remand for resentencing in light of that reversal. We reject Hertular’s remaining appellate arguments as without merit and, therefore, affirm his conviction in all other respects.
I. Background
A. Evidence Supporting the Challenged Counts of Conviction
The trial evidence convincingly demonstrated that in the period between 2001 and January 2004, Belizean national Robert Hertular conspired with others to import more than six tons of cocaine into the United States. Because Hertular raises no sufficiency challenge to his conviction
*436
on the conspiracy and substantive counts of narcotics trafficking, we do not detail this evidence further. Instead, we focus on the evidence adduced to prove the challenged counts of forcibly impeding or intimidating a federal officer and obstruction of justice. We summarize that evidence in the light most favorable to the government.
See, e.g., Jackson v. Virginia,
1. 2001: Hertular’s Initial Meetings with DEA Agent Williams
In mid-2001, Hertular was charged by Belizean authorities with trafficking in 1,161 kilograms of cocaine, which drugs Hertular admitted belonged to him and were destined for the United States. After securing bail release, Hertular initiated cellular telephone contact with Special Agent Vincent Williams, then assigned by the Drug Enforcement Administration (“DEA”) to Belize to investigate drug trafficking between that country and the United States. At that time, Agent Williams had never met Hertular, much less given him the agent’s unlisted cell phone number.
As a result of the call, Agent Williams and Hertular met on September 18, 2001, at which time Hertular expressed an interest in cooperating with United States authorities. Hertular generally described his drug trafficking operation, identifying various Belizean government officials as confederates. He admitted to transporting large quantities of cocaine by plane and speedboat from Colombia to Belize and to using VHF radios and satellite phones to communicate with his fellow traffickers during transport operations.
Agent Williams and Hertular met again on December 13, 2001, at which time Hertular gave the agent a VHF radio and satellite phone that he indicated had been used to coordinate a May 2001 cocaine shipment. At this meeting, however, Agent Williams informed Hertular that the DEA would not use him as a confidential informant. The agent had no further contact with Hertular until April 2003.
2. April 11, 2003: Hertular’s Uncharged Threat to Agent Williams
On April 11, 2003, Agent Williams was surveilling the Belize residence of confidential informant Liston McCord when he observed Hertular entering the premises. Both Agent Williams and McCord testified at trial to the events that ensued.
Specifically, McCord testified that, once inside his home, Hertular told him that a vehicle belonging to DEA agents was parked outside the premises. When McCord feigned indifference, Hertular advised him to get rid of the ear.
Moments later, Agent Williams called McCord to inquire about defendant’s presence. Although McCord took this call out of Hertular’s presence, when the conversation concluded, Hertular asked the informant if he was cooperating with the DEA. McCord denied any such involvement, and Hertular again advised him to get rid of the surveilling agents, going so far as to offer McCord hand grenades to achieve that goal. When McCord responded that there was no need to “get that drastic,” Hertular stated that he could get McCord “anything” he wanted. Trial Tr. at 379. Hertular even offered to “get rid of’ the agents himself, but McCord declined, stating that he had nothing to hide from the DEA. Id.
After Hertular left McCord’s home, Agent Williams followed defendant and signaled him to pull over into a parking lot. There, Agent Williams warned Hertular to “be mindful of his associations.” Id. at *437 540. Agent Williams testified that this incensed Hertular, who replied that he could “associate with anybody he want[ed]” and reminded Agent Williams that he was a guest in Belize. Id. Hertular stated that “he was tired of the DEA and the American Embassy” and that he was “willing to kill a DEA agent or an American Embassy” employee. Id. at 541. In response to this threat, Agent Williams warned Hertular that if he were to “make[] a hit” on the agent, Hertular should “make sure that he does it right the first time because he won’t get a second chance.” Id.
Agent Williams reported Hertular’s threat to American Embassy officials. In response, the Embassy threat level was raised and extra security measures were implemented. For example, Hertular’s photograph was circulated to all Embassy employees, and a “two-man rule” was implemented, requiring all agents and Embassy personnel to travel in pairs.
3. December 25, 2003: Hertular’s Charged Threat to Agents Williams and Kelly
By the end of 2003, the DEA had opened a formal investigation into Hertular’s drug trafficking activities and was conveying its findings to Assistant United States Attorneys in the Southern District of New York with a view toward securing a federal indictment.
On December 25, 2003, Hertular called DEA Agent Raymond Kelly (recently assigned to Belize) on his cell phone and requested a meeting near the residence of another DEA agent. Agent Kelly’s cell phone number, like that of Agent Williams, was unlisted and should have been unavailable to Hertular. Similarly, there was no obvious way in which Hertular could have obtained the residential addresses for DEA agents stationed in Belize.
Agents Kelly and Williams met Hertular that same day at the designated site. As the three men sat in Kelly’s car, Hertular stated that he knew he was the subject of a DEA investigation and that an indictment was likely to be returned against him in the near future. He told the agents that “he didn’t want [that] to occur.” Id. at 549. When Agent Kelly denied any investigation, Hertular promptly rebutted the denial by playing the tape recording of an intercepted conversation between Kelly and a confidential DEA informant regarding Ralph Fonseca, a senior Belizean government official with whom Hertular was suspected of trafficking drugs. Hertular explained that DEA telephones — both cellular and landline — had been tapped, that a call had been intercepted between Agent Williams and an Assistant United States Attorney discussing the possibility of Hertular’s indictment, that individuals within the American Embassy routinely provided Hertular with information, and that he knew the identities of several DEA informants. Hertular stated that he wanted the investigation against him stopped, in return for which he would consider cooperating with the DEA.
In the ensuing conversation, Hertular admitted that, since 1987, he had been a member of the “Fonseca organization,” a group involved in drug trafficking and money laundering in the United States and Europe. Hertular implicated a former Belizean prime minister and police commissioner in the organization and identified the Belize Alliance Bank as the entity used for money laundering. Hertular stated that his further cooperation would depend on DEA agreeing in writing to various demands, for example, allowing defendant to live in Europe. The agents indicated that they would have to consult with their superiors and the prosecutors. Meanwhile, they asked Hertular for a copy *438 of the recorded conversation that he had played for them.
Hertular left the scene to make a copy of the requested recording. When he returned a half hour later, his attitude was confrontational. Specifically, Hertular refused to give the agents a copy of the requested tape, stating that he intended to give it instead to Fonseca. Further, Hertular made statements to the agents that are the basis for the § 111 charge in this case. Specifically, Hertular told the agents it would be in their “best interest to back down from this investigation because he would have to protect himself.” Id. at 553. When Agent Kelly asked Hertular if he was suggesting that the safety of DEA agents in Belize was in jeopardy, Hertular replied that the agents better “protect” themselves and “watch [their] backs, because the Fonseca organization would hire hit men from Colombia or Mexico to take [the agents] out.” Id. Agent Kelly dismissed Hertular’s threats with an expletive, whereupon the agents ended the meeting.
The agents — who lacked arrest authority in Belize — did not attempt to take Hertular into custody for threatening their lives. They did, however, advise Embassy officials of these threats. As a result, not only was the two-man rule again put into effect, but additional DEA agents and arms were dispatched to Belize, guards were stationed outside agents’ homes, new procedures were implemented for agents leaving their homes or driving around town, and all agents were required to use phone cards, rather than their cell phones, to conduct business.
B. Court Proceedings Against Hertular
1. Arrest, Extradition, and Trial
On January 7, 2004, approximately two weeks after the events just detailed, a grand jury sitting in the Southern District of New York returned an indictment charging Hertular with two counts of drug trafficking, forcibly impeding and intimidating a federal officer, and obstruction of justice. In response to a formal request from the United States, Belizean authorities arrested Hertular on January 27, 2004, and, on or about July 24, extradited him to the Southern District of New York to face trial. Hertular was tried on a superseding indictment and, on March 1, 2006, a jury found him guilty on the four counts for which he now stands convicted. 2
2. Sentencing
Hertular’s pre-sentence report recommended an offense level of 45, which, with a criminal history of I, yielded a Guidelines sentencing range of life imprisonment. Defendant disputed this calculation insofar as his offense level reflected a two-point enhancement for possession of a dangerous weapon pursuant to U.S.S.G. § 2Dl.l(b)(l) and another two-point enhancement for obstruction of justice pursuant to U.S.S.G. § 3C1.1. As to the first challenge, Hertular argued that there was no evidence that he ever actually possessed the grenade he offered to supply McCord. As to the second, he submitted that a § 3C1.1 enhancement would constitute impermissible double counting in light of his conviction for obstruction of justice. *439 The district court rejected both arguments as meritless. Moreover, because it concluded that the obstruction of justice enhancement was “surely appropriate,” the district court observed that the weapon possession enhancement was irrelevant as Hertular’s Guidelines range would have provided for life imprisonment even at offense level 43. Sentencing Tr. at 14 (Mar. 22, 2007).
The district court did not, however, sentence Hertular to life imprisonment. After hearing from the parties as to how the factors specified in 18 U.S.C. § 3553(a) should be weighed, the district court decided that a non-Guidelines sentence was sufficient to serve the sentencing goals identified in that statute. Accordingly, it sentenced Hertular to prison terms of 400 months on each of the two drug trafficking counts, 12 months for forcibly impeding a federal officer, and 120 months for obstruction of justice, all terms to run concurrently.
II. Discussion
A. The Sufficiency Challenges
Hertular asserts that the trial evidence was insufficient to support the jury’s guilty verdicts on the counts of forcibly impeding or intimidating a federal officer and obstruction of justice. The rule of constitutional sufficiency derived from the Due Process Clause states that no person may be found guilty “except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime ... charged.”
In re Winship,
Applying this stringent test, we conclude that the evidence was insufficient to support Hertular’s conviction for forcibly impeding a federal officer but sufficient to support his conviction for obstruction of justice.
1. Forcibly Impeding or Intimidating a Federal Officer
Title 18 U.S.C. § 111(a)(1) states that any person who “forcibly assaults, resists, opposes, impedes, intimidates, or interferes” with a federal officer while the officer is “engaged in or on account of the performance of official duties” is guilty of a crime. 3 Hertular asserts that the trial evi *440 dence was insufficient to satisfy the statute’s “force” element because no proof was adduced that his threats to murder DEA agents posed immediate harm. As discussed below, our precedent applying § 111 to threats requires some proof of the assailant’s present ability to inflict injury giving rise to an objectively reasonable apprehension of immediate harm. Because such proof was lacking in this case, we are obliged to identify merit in this part of Hertular’s sufficiency challenge and to reverse his conviction on the § 111 count.
As the Supreme Court has observed, Congress’s purpose in enacting § 111 was expansive: “to protect both federal officers and federal functions ... [. Ijndeed, furtherance of the one policy advances the other.”
United States v. Feola,
In
Bamberger,
we declined to construe the statute’s force element so narrowly as to require the actual
use
of physical force to support a § 111 conviction. We held that
threats
of force could also support a § 111 conviction in certain circumstances.
See id.
For a threat to satisfy the force element of § 111, however, we required proof that the alleged threat would objectively inspire fear of pain, bodily harm, or death that is likely to be inflicted immediately.
See United States v. Walker,
Those core principles still inhered in the statute after its 1994 amendment, which, in relevant part, used the term “simple assault” to classify a misdemeanor violation. 18 U.S.C. § 111 (2003). As we noted in
United States v. Chestaro,
In its appellate brief, the government devotes considerable effort to demonstrating that Hertular’s statements to Agents Kelly and Williams satisfy the first prong of this test, a point that defendant does not — and could not — dispute. The trial evidence would certainly permit a reasonable jury to find that Hertular’s threats were real and that he had the ability to put them into effect. Thus, the threats could instill an objectively reasonable fear of pain, bodily harm, or death in any United States official stationed in Belize who
*441
heard them. Indeed, to the extent subjective responses can be relevant to objective assessments, the significant protective actions taken by United States authorities in Belize in response to Hertular’s charged threats support this conclusion.
See United States v. Walker,
Discussing this immediacy requirement in
Temple,
we stated that “[a]n implied threat to use force sometime in the indefinite future” is insufficient to support a § 111 conviction.
United States v. Temple,
The Eleventh Circuit has similarly construed § 111, holding in
United States v. Fallen
that the threat to inflict the injury must be “coupled with an apparent present ability” actually to inflict it.
*442
The facts in this case are not at all akin to
Fallen.
When Hertular told Agents Kelly and Williams that it was in their interest “to back down” from their investigation into his narcotics trafficking “because he would have to protect himself,” he did not indicate by word or deed that he was then armed or even that he was contemplating any present action against the agents. Trial Tr. at 553. Rather, Hertular threatened the agents with death at some unspecified future time, telling them to “watch [their] backs,” because if they continued to conduct their investigation, “the Fonseca organization would hire hit men from Colombia or Mexico to take [them] out.”
Id.
This is somewhat analogous to the threat of future harm referenced in the jury charge approved in
Walker
to illustrate circumstances inadequate to support a § 111 conviction.
See United States v. Walker,
The government nevertheless argues that a jury could have inferred from the totality of the circumstances that it was objectively reasonable for the agents to have feared immediate harm. Hertular was, after all, a large-scale drug trafficker who had, on two occasions, explicitly threatened to kill United States officials. He communicated the charged threat at a meeting with the agents that took place at night in a car in a foreign country in a relatively deserted area. Moreover, Hertular had demonstrated his ability to gain access to DEA agents’ private telephone numbers and home addresses. Further, he had offered to supply another person with a deadly weapon, a hand grenade, to get rid of DEA agents, a fact that Agent Williams knew at the time of Hertular’s charged threat.
To be sure, these circumstances would have instilled in the agents an objectively reasonable fear that Hertular’s homicidal threats were serious and real. Under our precedents, however, that is not sufficient to permit a reasonable factfinder to conclude that the agents were being threatened with immediate harm. Hertular’s threats implied two conditions precedent to the execution of his homicidal threats: (1) the DEA would have to continue its investigation into Hertular’s activities and, if it did, (2) the Fonseca organization would hire hitmen in other countries and transport them to Belize to carry out the threat. Because such conditions suggest the expected passage of some time, a jury could not reasonably find that, when Hertular threatened the agents, he had the apparent
present
ability to take their lives so that the agents would have an objectively reasonable fear of immediate harm. No different conclusion is warranted from the agents’ on-the-spot dismissal of Hertular’s threat. Even if this action might have signaled to Hertular that the DEA would not cease its investigation, Hertular’s reference to hiring and transporting hitmen from other countries, coupled with the total lack of evidence that Hertular was then armed or ready to take action against the agents, precluded a jury finding that the agents faced an objectively reasonable threat of immediate harm.
See United States v. Temple,
In identifying a sufficiency defect with respect to Hertular’s § 111 conviction, we by no means suggest that persons may threaten the lives of federal law enforcement officers with impunity, as long as they do not signal a present ability to inflict bodily harm. Quite the contrary. As this court noted at oral argument, 18 U.S.C. § 115(a)(1)(B) criminalizes “threat *443 en[ing] to assault, kidnap, or murder ... a Federal law enforcement officer ... with intent to impede, intimidate, or interfere with ... the performance of official duties.” Because this statute contains no force element, there is no burden to prove a defendant’s present ability to execute the threat giving rise to an objectively reasonable fear of immediate bodily harm.
In a post-argument submission, the government concedes that “on its face,” § 115(a)(1)(B) covers Hertular’s conduct. Government’s June 20, 2008 Rule 28(j) Letter at 1. It notes simply that conduct can violate more than one statute, and it urges us to uphold the § 111 conviction in light of our recognition that the statute’s purpose is to “‘prohibit!] any acts or threats of bodily harm that might reasonably deter a federal official from the performance of his or her duties.’ ”
Id.
at 2 (quoting
United States v. Walker,
2. Obstruction of Justice
To the extent the same threatening conduct was the basis for Hertular’s obstruction conviction pursuant to 18 U.S.C. § 1512(b)(3),
5
defendant submits that the trial evidence was insufficient to permit a reasonable jury to find the requisite specific intent to interfere with the communication of information relating to the commission of a federal offense to a United States law enforcement officer.
See United States v. Genao,
The trial evidence shows that, on December 25, 2003, when Hertular threatened the lives of DEA agents, he knew that, in pursuit of an indictment against him and his confederates, information was regularly being communicated by confidential informants to DEA agents in Belize and from DEA agents to federal prosecutors in New York. Indeed, Hertular advised the agents that tape recordings of such conversations had been intercepted, and he even played one such recording for them. On this record, a reasonable fact-finder could easily have concluded that when Hertular told the agents it was in their “best interest to back down” from their investigation and warned them that “hit men from Colombia or Mexico” would be hired to “take [them] out,” Trial. Tr. at 553, his specific intent was to hinder or prevent not simply the filing of an indictment but any communication to or among federal law enforcement officials that could lead to his indictment.
See generally
*444
United States v. Veal,
B. The Jury Instruction Challenge
In charging the jury as to the specific intent element of obstruction of justice under 18 U.S.C. § 1512(b), the district court gave the following instruction:
By specific intent, I mean that the defendant must have acted knowingly and with the unlawful intent to hinder, delay or prevent the communication to a federal law enforcement officer or judge of the United States of information relating to the commission or possible commission of a federal offense. The defendant must have known or foreseen that the information was likely to result in or affect a judicial proceeding. However, the government need not prove that an official proceeding was pending or about to be instituted at the time of the defendant’s actions. I instruct you that a criminal prosecution, of which an indictment is a paid, qualifies as a judicial proceeding.
Trial Tr. at 983-84 (emphasis added). Hertular submits that the emphasized language manifests error because the language of § 1512(b), unlike that of other obstruction statutes, does not specify an intent to affect an official or judicial proceeding. See, e.g., 18 U.S.C. § 1510(d)(1) (specifying “intent to obstruct a judicial proceeding”); id. § 1512(a)(1)(A) (referencing intent to “prevent the attendance or testimony of any person in an official proceeding”); id. § 1512(a)(1)(B) (requiring intent to “prevent the production of a record. .. in an official proceeding”); id. § 1513(a)(1)(B) (making it federal crime to kill or attempt to kill “with intent to retaliate against any person” for providing specified information to law enforcement officer “pending judicial proceedings”). The argument is unconvincing for at least two reasons.
First, Hertular not only failed to object to the challenged charge — an omission that would normally limit our review to plain error,
see
Fed.R.Crim.P. 30(d), 52(b) — his counsel specifically “endorse[dj” it. Trial Tr. at 838 (stating, in response to government request to add highlighted language to charge, “With respect to that change, I endorse that change.”). Such endorsement might well be deemed a true waiver, negating even plain error review.
See generally United States v. Quinones,
Second, even on plain error review, Hertular’s challenge fails because he cannot demonstrate that the purported error is plain, much less that he sustained any prejudice or that the fairness, integrity, or public reputation of his judicial proceedings was called into question.
See United States v. Olano,
The trial record indicates that the challenged language in this case was proposed by the government, endorsed by the defendant, and included in the charge by the district court in order specifically to ensure the nexus finding specified in
Arthur Andersen.
To the extent the charge may have imposed an intent requirement beyond that strictly required by
Arthur Andersen
— a point we need not conclusively decide on this appeal — Hertular does not even attempt to show that he was prejudiced by the district court placing a heavier burden on the government,
see United States v. Kaplan,
Accordingly, even if Hertular’s endorsement of the challenged charge did not waive appellate review, we identify no plain error in the district court’s § 1512(b) instruction. We therefore affirm the obstruction of justice count of conviction.
C. The Sentencing Challenge
Hertular submits that his 400-month sentence is infected by procedural error and, in any event, is substantively unreasonable in light of sentences imposed on certain confederates. Because we vacate Hertular’s sentence in light of our reversal of his § 111 conviction, we do not decide the question of substantive reasonableness in advance of resentencing. Nevertheless, to facilitate the district court’s task on remand, we here explain why we identify no merit in defendant’s procedural challenges.
1. The Decision to Vacate and Remand for Resentencing Makes It Unnecessary to Consider Hertular’s Substantive Reasonableness Challenge
Where we overturn one or more counts of conviction but leave others in place, our general rule has been to remand for
de novo
sentencing proceedings.
See Burrell v. United States,
*446 A district court’s sentence is based on the constellation of offenses for which the defendant was convicted and their relationship to a mosaic of facts, including the circumstances of the crimes, their relations to one another, and other relevant behavior of the defendant. When the conviction on one or more charges is overturned on appeal and the case is remanded for resentencing, the constellation of offenses of conviction has been changed and the factual mosaic related to those offenses that the district court must consult to determine the appropriate sentence is likely altered. For the district court to sentence the defendant accurately and appropriately, it must confront the offenses of conviction and facts anew.
United States v. Quintieri,
In reversing Hertular’s § 111 conviction, we recognize that the conduct proved to support this count was clearly criminal under § 1512(b), and most likely under § 115(a)(1)(B). Thus, although our reversal of Hertular’s § 111 conviction changes the “constellation of offenses” relevant to sentencing, the “factual mosaic” may be little altered. Nevertheless, mindful that the law entrusts district courts, not courts of appeals, with the primary responsibility for weighing the totality of circumstances relevant to sentencing, we conclude that, even in these circumstances, we must vacate the defendant’s sentence and remand the case to the district court so that it may decide, in the first instance, whether a conviction on three rather than four counts affects its assessment of the sentencing factors detailed in 18 U.S.C. § 3553(a).
6
See Gall v. United States,
— U.S. -,
Only when the district court has made that assessment and entered a new final judgment would it be appropriate for a panel of this court to consider the substantive reasonableness of the sentence imposed. If Hertular were to appeal a sentence imposed on remand as substantively unreasonable, he would bear the burden identified by our recent precedents to show that the challenged sentence cannot be located within the “broad range” that can be deemed reasonable.
United States v. Jones,
2. Hertular’s Procedural Challenges Lack Merit
Hertular asserts procedural error in the district court’s calculation of his Sentencing Guidelines range.
See Gall v. United States,
a. U.S.S.G. § 3C1.1: Obstruction of Justice
Relying exclusively on his argument that the evidence was insufficient to support his convictions either for interfering with and intimidating a federal officer in violation of § 111 or for obstruction of justice in violation of. § 1512(b)(3), Hertular asserts that the district court erred in enhancing his offense level for obstruction of justice pursuant to U.S.S.G. § 3C1.1. It is not clear that Hertular preserved this argument in the district court.
See United States v. Gallerani,
First, we observe that “force” is not required to find obstruction under § 3C1.1. Therefore, the sufficiency problem we identify in this element of Hertular’s § 111 conviction is irrelevant to the application of § 3C1.1 to defendant’s Guidelines calculation.
Second, for the reasons discussed
supra
at 443^4, we determine that the evidence was sufficient to prove Hertular guilty beyond a reasonable doubt of obstruction of justice in violation of § 1512(b)(3). We therefore easily conclude that the evidence was sufficient to permit the district court to find obstruction by the lesser preponderanee-of-theevidence standard applicable to Guidelines determinations.
See United States v. Garcia,
b. U.S.S.G. § 2Dl.l(b)(l): Possession of a Dangerous Weapon
Hertular submits that the district court erred in applying a § 2Dl.l(b)(l) enhancement for possession of a dangerous weapon to his offense level calculation. He asserts that there was no evidence to support an inference that he actually possessed the weapon at issue, i.e., the hand grenades he offered to supply McCord. Hertular’s argument fails for two reasons.
First, the evidence was sufficient to support an inference that it was more likely than not that Hertular actually or constructively possessed the offered hand grenades.
See United States v. Herrera,
Second, even if the evidence could not support an offense level increase to 45 pursuant to § 2D 1.1(b)(1), that would not, by itself, have made any difference to the calculation of Hertular’s Guidelines sentencing range. As the district court observed, an offense level of 43 would also have yielded a recommended lifetime sentence. Thus, any misapplication of § 2D 1.1(b)(1) to this case would have constituted a harmless error in the Guidelines calculation not warranting resentencing.
See United States v. Lenoci,
c. U.S.S.G. § 3Bl.l(b): Role Enhancement
Hertular’s challenge to the district court’s application of a role enhancement to the calculation of his offense level merits little discussion. U.S.S.G. § 3Bl.l(b) provides for a three-level enhancement if a defendant “was a manager or supervisor (but not an organizer or leader)” in a criminal activity that involved “five or more participants or was otherwise extensive.” Hertular does not dispute that the drug conspiracy for which he was found guilty involved five or more participants. He argues only that he should not have been treated as a manager or supervisor because the enhancement was not applied to a similarly situated confederate prosecuted before a different judge. We are not persuaded.
A defendant is properly considered as a manager or supervisor under § 3Bl.l(b) if he “exercised some degree of control over others involved in the commission of the offense or played a significant role in the decision to recruit or to supervise lower-level participants.”
United States v. Blount,
In general, we review a district court’s determination that a defendant deserves a leadership enhancement under § 3B1.1
de novo,
but we review the court’s findings of fact supporting its conclusion only for clear error.
See United States v. Paccione,
Ample trial evidence supported the district court’s conclusion that Hertular had greater responsibility over the organization’s drug operations than an average member of the conspiracy. Specifically, Hertular or his confederates acknowledged that defendant dealt directly with both the organization’s Colombian suppliers as well as the Mexican transporters. Moreover, Hertular’s access to otherwise unavailable information about United States agents working in Belize and their informants, and to recorded conversations involving United States law enforcement officials both in Belize and in New York strongly supported the inference that he dealt with the various corrupt high-ranking officials in the Beh ize government who were integral to the conspiracy’s operations. Further, evidence demonstrated that Hertular recruited and directed persons involved in transporting drugs for the conspiracy.
See United States v. Blount,
Further reinforcing the conclusion that Hertular played a more significant role in the conspiracy than average participants was the fact that he threatened the lives of federal law enforcement agents investigating him and the conspiracy of which he was a member. On one occasion, he offered to secure hand grenades to perform the deed. On another occasion, he went out of his way to let agents know that he had access to confidential information about them and their informants. The district court was entitled to conclude that no average member of the conspiracy would have taken such aggressive action to protect the ongoing criminal scheme.
Accordingly, we identify no error, let alone plain error, in the district court’s use of a § 3B 1.1(b) role enhancement to calculate Hertular’s Sentencing Guidelines range preliminary to it imposing a non-Guidelines sentence.
D. The Pro Se Challenges
We have reviewed the various challenges raised by Hertular in his pro se filing with the court, and we readily conclude that they either are lacking in merit or cannot properly be considered on this appeal.
First, Hertular’s claim that he was never arraigned on the superseding indictment (“S2”) is belied by the docket sheet in this case, which contains a minute entry for Hertular’s S2 arraignment on February 15, 2006. Moreover, the transcript of proceedings held that day conclusively demonstrates Hertular’s arraignment on S2.
*450
Second, Hertular’s claim that there were defects in the provisional arrest warrant issued against him by Belizean authorities was a matter properly raised in his extradition proceedings in that country. United States courts do not review challenges to foreign authorities’ compliance with their own domestic law in granting a removal request by this country.
See generally United States v. Lira,
Third, Hertular’s argument that a third indictment was returned in his case and “intentionally with[held]” from him lacks any factual support in the record. Appellant’s
Pro Se
Br. at 10. In any event, the existence of such an indictment would not have precluded Hertular’s trial or conviction on S2.

Fourth, Hertular’s claim that the government failed in its Rule 16 obligations to produce a diplomatic note regarding his arrest from the United States to the Belizean government is factually belied by the record. A copy of the note in question was produced by the government. See Letter from Marvin E. Schechter, counsel to defendant, to the Honorable Naomi Reice Buchwald, Feb. 27, 2006, at 1 (acknowledging government’s production of diplomatic note). Hertular’s unsworn and unsupported statement that he saw a different diplomatic note warrants no further inquiry, much less reversal of his conviction.
Fifth, Hertular’s assertion that the government suppressed the Belizean search warrant authorizing a search of his brother’s home similarly lacks any record support. The record demonstrates that the warrant was, in fact, introduced into evidence at trial.

Finally, Hertular’s claim of ineffective assistance of counsel is more appropriately raised on a motion brought under 28 U.S.C. § 2255.
See Massaro v. United States,
III. Conclusion
To summarize, we reach the following conclusions:
1. Hertular’s conviction for forcibly impeding or intimidating federal officers in violation of 18 U.S.C. § 111 must be reversed because the evidence was insufficient to permit any reasonable jury to make the finding required by our precedents, i.e., that when defendant threatened the lives of DEA agents, he did so with the present apparent ability to carry out the threat so as to give rise to an objectively reasonable fear of immediate harm.
2. Hertular’s conviction for obstructing justice in violation of 18 U.S.C. § 1512(b)(3) is supported by sufficient evidence of the requisite intent because, at the same time Hertular threatened the lives of DEA agents if they continued their investigation into his criminal activities, Hertular expressed awareness of their communications with federal prosecutors in an effort to secure his indictment.
3. Hertular’s challenge to the jury charge on obstruction of justice fails because (a) his endorsement of the charge in the district court manifests a true waiver precluding appellate review and, in any event, (b) he cannot demonstrate plain error because the alleged defect only increased the government’s burden of proof and caused no prejudice to the defendant.
4. Because we reverse Hertular’s § 111 conviction, we vacate his sentence and remand for resentencing. Because that resentencing may yield a different sentence, we do not at this time consider Hertular’s argument that the vacated sentence is substantively unreasonable. We do, however, reject as without merit Hertular’s claim of procedural error with respect to the district court’s calculation of his Sentencing Guidelines range, a calculation not affected by our § 111 reversal.
5. Hertular’s pro se arguments are either without merit or not properly considered on this appeal.
Accordingly, we reverse Hertular’s conviction for violating 18 U.S.C. § 111, we affirm the district court’s judgment as to the remaining three counts of conviction, and we vacate that part of the judgment pronouncing sentence and remand the case for the limited purpose of resentencing in light of our reversal of the § 111 count.
Affirmed in Part, Reversed in Part, Vacated and Remanded in Part.
Notes
. The superseding indictment added no new charges against Hertular. To the contrary, with respect to 18 U.S.C. § 111, it deleted the charge for attempting to impede and intimidate a federal official, leaving only the charge of actually impeding and intimidating. Other changes effected by the superseding indictment — the substitution of a "hand grenade” for "hand grenades” and the inclusion of the word "forcibly” in the § 111 count — clarified the original charges but did not change them.
. Where the proscribed conduct involves "only simple assault,” the crime is a misdemeanor punishable by a term of imprisonment of “not more than one year.” 18 U.S.C. § 111(a) (2003). Because the government acknowledges that this was the maximum sentence faced by Hertular, we review defendant's sufficiency challenge as it applies to a misdemeanor violation of the statute and not as it might apply to felony or aggravated-felony offenses.

v.
Chestaro,
. The Eleventh Circuit rejected Fallen's argument that his failure to display a firearm precluded a finding of immediacy. The court sensibly observed that "concealed assailants who assert that they are in possession of a loaded firearm do so at their peril. When the totality of the circumstances supports a reasonable inference that the assailant is armed, a law enforcement officer is entitled to take the assailant at his word."
United States v. Fallen,
. That statute provides, in relevant part,
(b) Whoever knowingly uses intimidation, threatens, or corruptly persuades another person, or attempts to do so, or engages in misleading conduct toward another person, with intent to — •...
(3) hinder, delay, or prevent the communication to a law enforcement officer or judge of the United States of information relating to the commission or possible commission of a Federal offense ... shall be fined under this title or imprisoned not more than ten years, or both.
18 U.S.C. § 1512(b)(3).
. We express no view as to whether the district court, on resentencing Hertular for the three counts of conviction that we affirm, should impose the same total terms of incarceration and supervision on remand. We have no doubt, however, that the district court will reduce that part of the judgment ordering consecutive special assessments to reflect the reversal of one count of conviction.
. In the district court, Hertular did not challenge the sufficiency of the evidence to support a § 3C1.1 enhancement. Rather, he argued that application of § 3C1.1 to his case would involve impermissible "double counting” of crimes of conviction. The latter argument was rejected below and not renewed on appeal.
. Article 14, Section 1(a) of the Treaty states:
1. A person extradited under this Treaty may not be detained, tried, or punished in the Requesting State except for:
(a) the offense for which extradition has been granted or a differently denominated offense based on the same facts on which extradition was granted, provided such offense is extraditable, or is a lesser included offense.
