    Before JORDAN, JULIE CARNES, and LINN, ∗ Circuit Judges.
    JULIE CARNES, Circuit Judge:
    ∗
    Honorable Richard Linn, United States Circuit Judge for the Federal Circuit, sitting by
    designation.
    Case: 13-14843       Date Filed: 12/11/2015       Page: 2 of 46
    For less than a year, Defendant Fausto Aguero Alvarado worked as an
    undercover confidential informant (“CI”) for the United States Drug Enforcement
    Administration (“DEA”) in Central America. Formalizing this role, he signed
    written agreements with federal DEA agents that set out the parameters of his
    duties, and thereafter assisted these agents with investigations into drug and
    weapons trafficking operations. After working with the agents for a few months,
    Defendant apparently came to the realization that he could make more money by
    actually dealing drugs and weapons than by merely reporting on those who do. So,
    deciding to make a career change, Defendant began working in earnest with some
    of the drug traffickers on whom he had been gathering intelligence, as well as
    some new acquaintances, in an effort to trade weapons for large quantities of
    cocaine. Not surprisingly, Defendant kept this new entrepreneurial venture to
    himself, conceding that he never at any time, during a criminal conspiracy that
    spanned sixteen months,1 informed his supervising federal agents what he was up
    to or that there was even a weapons-for-drugs transaction in the offing with his
    new-found working partners. In fact, these supervising agents had no idea that
    Defendant had been involved in the conspiracy that ultimately led to his indictment
    1
    Often in its brief, the Government refers to the length of the conspiracy as being nineteen
    months. It may well be that the conspiracy lasted that long, but inasmuch as the dates for the
    conspiracy listed in the indictment (June 2009–October 2010) span only sixteen months, the
    latter number will be used throughout this opinion.
    2
    Case: 13-14843      Date Filed: 12/11/2015    Page: 3 of 46
    until they were later informed by other law enforcement officials who had
    uncovered Defendant’s criminal activities.
    At trial, Defendant did not deny that he and his fellow conspirators planned
    and took steps to trade weapons in exchange for obtaining large quantities of
    cocaine. His explanation, which he offered in his trial testimony before the jury,
    was that throughout his involvement in the charged conspiracy, he considered
    himself to be acting in his capacity as an informant, merely gathering intelligence
    as part of that role. But as to when he planned to actually share with supervising
    agents his sixteen months of covert “intelligence gathering,” such a conversation
    was apparently never on Defendant’s “to-do” list.
    In its instructions, the district court explained that the jury should find
    Defendant not guilty if it concluded that he had honestly believed he was
    performing the charged criminal conduct to help law enforcement. The jury
    convicted Defendant on the sole count of the indictment: conspiracy to distribute
    five kilograms or more of cocaine with knowledge that it would be imported into
    the United States.
    Defendant now appeals his conviction, as well as the sentence subsequently
    imposed by the district court. As to his conviction, Defendant argues that,
    although the district court had given the above-described “honest belief”
    instruction, it erred by refusing to also instruct the jury that it should consider
    3
    Case: 13-14843     Date Filed: 12/11/2015    Page: 4 of 46
    whether authorities had actually authorized Defendant to engage in the charged
    conduct. He also cites as error the court’s refusal to allow Defendant to call an
    expert witness who would have testified that the agents supervising Defendant did
    not run their operation in complete compliance with DEA regulations. As to his
    sentence, Defendant argues that the 360-month, within-Guidelines, sentence
    imposed by the court was substantively unreasonable. After careful review of the
    record and with the benefit of oral argument, we affirm Defendant’s conviction and
    sentence.
    BACKGROUND
    I.    Factual Background
    A.     Defendant’s CI Work
    In 2008, while living in Colombia, Defendant obtained some information
    regarding weapons and narcotics activity. Having worked as a CI in the past, he
    had received training in field operations and intelligence gathering. Accordingly,
    around April of 2008, Defendant went to the United States Embassy in Bogota,
    Colombia, to share his recently-gained intelligence with the DEA. After providing
    a previously-assigned code that identified him as a former CI, Defendant met with
    DEA Agents Matthews and Romain and offered them information that was
    potentially useful to the dismantling of a drug trafficking cartel.
    4
    Case: 13-14843      Date Filed: 12/11/2015   Page: 5 of 46
    Other meetings followed this first session, and Agent Romain decided that
    he wanted to use Defendant to infiltrate an organization in which one undercover
    operative was already working. Accordingly, on August 28, 2008, Defendant and
    Agent Romain entered into a contract formally authorizing Defendant to work as a
    CI. The agreement made clear that Defendant would have no immunity from
    prosecution for activities that were not specifically authorized by his controlling
    investigators. Further reinforcing that condition, the contract required Defendant
    to agree that he would take no independent action on behalf of the DEA or the
    United States government. The term of the agreement was one year, meaning that
    it would expire in August 2009.
    Defendant then began providing Romain with information about Franklin
    McField-Bent, a Nicaraguan national known to authorities as the supplier of a
    transportation service used by drug dealers to move cocaine from the interior of
    Colombia, to the Nicaragua/Honduras border, to Guatemala, and then to Mexico.
    Romain sought Defendant’s assistance as part of his effort to build a case against
    McField-Bent and the Titos Montes trafficking organization.
    Also in August 2008, Defendant began working with DEA Agent Ball in
    Honduras on an investigation into a terrorist named Jamal al Yousef. Ball and
    Defendant worked closely together during the investigation. Some of Defendant’s
    phone calls to targets in the Jamal al Yousef investigation were recorded under
    5
    Case: 13-14843    Date Filed: 12/11/2015   Page: 6 of 46
    Ball’s direction and Ball met with Defendant, both before and after key meetings
    with targets, to instruct and debrief him. Defendant was paid $8,800 for his work
    sometime in 2008 and worked on the investigation until March 2009.
    In early September 2008, Defendant signed two other CI agreements, each
    with a one-year term, with DEA Agents Sanes and Peterson, who were working in
    Honduras and Panama, respectively. Like the first agreement with Agent Romain,
    these agreements reiterated that Defendant could not act independently of his
    controlling agents. On October 2, 2008, Defendant met with both Agents Romain
    and Sanes to share information about McField-Bent. Then, sometime between
    October and December 2008, as a result of safety and security issues, Agent Ball
    instructed Defendant to leave Honduras.
    By January 2009, Defendant’s work and contact with the above agents had
    largely ceased, the exception being some continued work with Agent Ball on the al
    Yousef terrorist investigation, which ended in March 2009. Indeed, in January
    2009, Defendant emailed Agent Ball, informing him that Agent Romain had told
    him to “fruck off” and leave Colombia as soon as possible because “you guys
    didn’t want to work with me” any longer. It was around this time that Agent Ball
    became aware of an ongoing investigation into Defendant’s unauthorized criminal
    activities. In fact, by May, Agent Romain had left Colombia and had no further
    contact with Defendant.

    B.      Defendant’s Involvement in Charged Conspiracy
    According to the evidence presented at trial, 2 Defendant was integrally and
    actively involved in the charged criminal conspiracy, which spanned over sixteen
    months. The overarching goal of the conspiracy was to obtain large quantities of
    cocaine, after which the transportation services of McField-Bent would be utilized
    to transport the drugs from Colombia to Mexico; thereafter, the drugs would be
    moved across the border to the United States. Defendant focused much of his
    efforts on acquiring drugs by trading weapons with an individual who could supply
    those drugs. This individual, Jaime Velasquez, purportedly was the commander of
    an illicit Colombian paramilitary group known as Autodefensas, which group very
    much wanted weapons. In actuality, Velasquez was an undercover operative who
    was working for both the Colombian government and the United States
    Department of Homeland Security.
    Defendant was introduced to Velasquez as a potential weapons supplier and,
    in a telephone conversation on June 12, 2009, Velasquez and Defendant discussed
    Velasquez’s desire to order SAM-7 missiles. 3 Defendant explained that he could
    2
    We take the evidence in the light most favorable to the Government. See United States v.
    Cavallo, 
    790 F.3d 1202
    , 1229 (11th Cir. 2015). That said, neither at trial nor on appeal has
    Defendant disputed his conduct during the charged conspiracy. Instead, he has argued that
    because he had been an informant, the Government should be deemed to have authorized him to
    undertake these actions.
    3
    The SAM-7 missile is a Soviet-built, shoulder-launched, surface-to-air missile. The purpose of
    this missile is to launch air defense attacks and to force low-flying aircrafts into higher altitudes
    7
    Case: 13-14843        Date Filed: 12/11/2015      Page: 8 of 46
    be the intermediary for a potential exchange. Three days later, at an in-person
    meeting with Velasquez and others, Defendant stated that he worked with a “really
    good office,” which Velasquez understood to mean a good drug trafficking
    organization. Velasquez suggested that they start with a deal for six grenade
    launchers, which Defendant would arrange to have transported from Honduras to
    Colombia. Defendant proposed an exchange of one kilogram of cocaine for each
    grenade launcher. Defendant also told Velasquez that he could exchange cocaine
    for weapons in Central America and that McField-Bent was in charge of the drug
    transportation logistics. At some point during the meeting, Defendant had a
    telephone conversation with McField-Bent in which he mentioned that a woman
    named Lina Ester Grendet had given him “the terrain, that farm already, that
    1,000-meter property,” which Velasquez understood to mean that Lina had given
    Defendant 1,000 kilograms of cocaine.4 Defendant explained that he was
    purchasing the cocaine from Lina for $7,000 per kilogram and planned to sell it for
    $9,500 to an individual named David.

    4
    Throughout his dealings with Velasquez, Defendant used code words when discussing
    weapons or drugs. Likewise, he urged Velasquez to be vigilant as to the possibility of wire
    interceptions.
    8
    Case: 13-14843    Date Filed: 12/11/2015   Page: 9 of 46
    One month later, at a meeting on July 25, 2009, Velasquez again expressed
    interest in purchasing missiles from Defendant. Defendant asked Velasquez if
    Velasquez could help him recover some money that Lina owed him. Velasquez
    understood Defendant to be asking him to put pressure on Lina to pay back this
    money to Defendant. Defendant sent Velasquez an email with Lina’s contact
    information, including her address and a photograph of her. That same month,
    Defendant received two payments via wire transfer: one from Velasquez and one
    from Lina.
    Negotiations between Velasquez and Defendant and his group concerning
    this guns-for-drugs initiative continued for months until, finally, in May 2010,
    Defendant, McField-Bent, Jeison Archibold, and a Miguel Vilella met with
    Velasquez, who agreed to provide 400 kilograms of cocaine to Defendant’s group
    every twenty days in exchange for rocket-propelled grenade launchers, grenades,
    and other weapons. Talks continued and the deal was to be finalized with
    Velasquez at a meeting on October 8, 2010. But instead, Colombian officials
    arrested the conspirators at this meeting. Defendant, who was in Bogota and not
    present at that meeting, was arrested a month later.
    Although the weapons-trading aspect of the conspiracy was a focus of
    Defendant’s work, Defendant was also involved in other efforts by the group to
    acquire drugs independently of Velasquez. For example, in March 2010,
    9
    Case: 13-14843    Date Filed: 12/11/2015   Page: 10 of 46
    Defendant, McField-Bent, and Archibold shipped a load of cocaine that was later
    seized en route to Honduras by Colombian authorities. Recorded conversations
    revealed discussion of an additional shipment in May 2010. In addition, as set out
    above, Defendant had purchased cocaine from Lina at some point prior to June
    2009.
    Notably, most of the above-described events occurred after the August and
    September 2009 expiration dates of Defendant’s CI agreements with the federal
    agencies. All of them occurred after Agent Romain had told Defendant that the
    agents no longer wanted to work with him. And at no time during the sixteen-
    month conspiracy did Defendant ever inform any of his supervising agents that
    these very significant criminal acts were occurring or that he was involved in their
    planning.
    II.     Procedural Background
    On October 8, 2010, Defendant’s co-conspirators were arrested. A month
    later, on November 11, 2010, Defendant suffered the same fate. A Honduran
    national, Defendant was arrested in Colombia on charges that he had conspired to
    traffic in arms and had possessed a false Colombian identification card.
    Represented by counsel, Defendant explained to prosecutors that his arrest was a
    mistake because he was actually an undercover informant for the United States
    DEA and FBI. Requesting and receiving access to his iPhone so that he could
    10
    Case: 13-14843      Date Filed: 12/11/2015      Page: 11 of 46
    show authorities the reports he had sent by email to American federal agents,
    Defendant was able to open his email account, but could point to no emails sent to
    federal agents. Ultimately, Defendant was unable to provide any proof to
    Colombian authorities that he was an informant for American law enforcement
    officials.
    In February 2011, Defendant pled guilty to these Colombian charges,
    admitting that he had participated in meetings with Archibold and Velasquez on
    June 15 and July 25, 2009, that 442 kilograms of cocaine and numerous weapons5
    had been seized by authorities on March 17, 2010, and that he had purchased a
    false Colombian identification card.
    A month prior to this guilty plea, in January 2011, Defendant, along with
    McField-Bent, Archibold, and others, was indicted on federal charges in the United
    States. The indictment charged Defendant with (1) conspiracy to provide material
    support and resources (namely, grenade launchers and other weapons) to a
    Colombian terrorist organization, in violation of 18 U.S.C. §§ 2339A(b)(1) and
    2339B(a)(1), and (2) conspiracy to distribute five kilograms or more of cocaine,
    knowing that it would be unlawfully imported into the United States, in violation
    of 21 U.S.C. §§ 959(a)(2), 960(b)(1)(B), and 963.
    5
    Defendant acknowledged that 24 grenades, 6 grenade launchers, an unspecified number of
    semi-automatic rifles, and 100 rounds of 9 mm ammunition had been seized by authorities.
    11
    Case: 13-14843        Date Filed: 12/11/2015        Page: 12 of 46
    But when American federal prosecutors (“the Government”) attempted to
    extradite Defendant from Colombia to try him on these charges, Colombian
    authorities refused to extradite Defendant unless the Government agreed that he
    would not be charged with the § 2339A weapons offense. The Government
    agreed, and in June 2013, a superseding indictment was returned charging
    Defendant with only one count: conspiracy to distribute five kilograms or more of
    cocaine, knowing that it would be unlawfully imported into the United States.
    Co-defendants McField-Bent and Archibold both pled guilty, with McField-
    Bent later testifying as a Government witness at Defendant’s trial. Defendant,
    however, decided to go to trial for the purpose of arguing that he had been
    authorized by federal agents to engage in the charged criminal activity. As
    required by Federal Rule of Criminal Procedure 12.3(a)(1),6 Defendant filed a
    pretrial notice of intent to present a public authority defense and included a list of
    federal agents for whom he had worked. The notice indicated that Defendant had
    worked for all the listed agents between 2008 and 2011.
    In response, the Government filed a motion in limine to preclude Defendant
    from raising a public authority or entrapment-by-estoppel defense. The motion
    noted that Defendant had proffered no evidence that he was authorized to
    6
    “If a defendant intends to assert a defense of actual or believed exercise of public authority on
    behalf of a law enforcement agency or federal intelligence agency at the time of the alleged
    offense, the defendant must so notify an attorney for the government in writing and must file a
    copy of the notice with the clerk [of court].” Fed. R. Crim. P. 12.3(a)(1).
    12
    Case: 13-14843       Date Filed: 12/11/2015      Page: 13 of 46
    participate in any of the illicit meetings or calls occurring during the conspiracy.
    Indeed, having broken off contact with agents during this time period, Defendant
    had failed even to notify agents of those meetings and calls. Further, the written
    agreements that Defendant signed explicitly stated that he was not authorized to
    participate in any criminal activity unless specifically authorized in writing by a
    prosecutor or his controlling agents. In short, the motion contended that the above
    defenses were unavailable to Defendant absent his production of evidence
    demonstrating that he was specifically authorized to engage in the conduct charged
    in the indictment.
    Responding to the Government’s motion, Defendant argued that the public
    authority defense should be available to him. 7 He argued that he had “general”
    authorization to gather intelligence and therefore was not required to prove that an
    agent had affirmatively authorized any particular conduct. He further argued that
    he should also be permitted to present an innocent intent defense, which he
    contended is merely another way of arguing that a defendant lacks mens rea.
    The magistrate judge held a hearing on the Government’s motion. Although
    a defendant must first show authorization to commit the charged criminal conduct
    before he will be permitted to assert a public authority defense, Defendant
    presented no testimony to establish a factual basis for his position. The
    7
    Defendant also mentioned the entrapment-by-estoppel defense, but ultimately did not pursue
    that defense.
    13
    Case: 13-14843     Date Filed: 12/11/2015    Page: 14 of 46
    Government likewise called no witnesses. Instead, the hearing consisted of only
    arguments from each party as to how specific an affirmative communication from
    a Government agent must be to provide authority for an informant’s actions.
    Because Defendant had presented no evidence of “any direct or implied
    affirmative representation sufficient to establish the defense[] of public authority,”
    and no evidence to establish the reasonableness of his alleged belief that he was
    working for the DEA while involved in the conspiracy, the magistrate judge
    recommended that the district court disallow Defendant’s public authority defense.
    The magistrate judge agreed, however, that Defendant should be permitted to argue
    an innocent intent theory of defense: that is, that Defendant honestly believed he
    was working for the DEA.
    Defendant had also filed a pretrial notice of intent to rely upon expert
    testimony from a former DEA agent who would testify that the DEA agents who
    supervised Defendant did not follow the agency procedures in place for activating,
    deactivating, and terminating CIs. Finding persuasive the Government’s motion to
    exclude this agent’s testimony, the magistrate judge determined that, because the
    pivotal issue at trial would concern whether Defendant honestly believed that he
    was acting on behalf of the DEA while participating in the charged conspiracy, an
    expert’s testimony about the extent to which the supervising agents followed
    procedures would shed no light on this matter. Further, according to the magistrate
    14
    Case: 13-14843      Date Filed: 12/11/2015   Page: 15 of 46
    judge, any opinion by the expert as to Defendant’s likely beliefs would violate
    Federal Rule of Evidence 704(b), which prohibits expert testimony about whether
    a defendant had a mental state that constitutes an element of a charged offense or
    defense.
    The district court adopted the magistrate judge’s recommendation to exclude
    both the public authority defense and the expert witness. At trial, the Defendant
    testified about his involvement in the charged conspiracy and his belief that he had
    been authorized by federal agents to act as he did. The district court concluded
    that Defendant had still failed to offer evidence that would support a public
    authority defense. The court, however, permitted Defendant to argue innocent
    intent, and it also charged the jury on that theory of defense. The jury found
    Defendant guilty on the single count of the indictment. The district court
    sentenced Defendant to 360 months’ imprisonment and five years’ supervised
    release. This appeal followed.
    DISCUSSION
    I.    District Court’s Refusal to Give Defendant’s Requested Instruction on
    the Public Authority Defense
    As noted, at the hearing before the magistrate judge concerning whether
    Defendant would be permitted to present a public authority defense, Defendant
    failed to present any evidence to qualify him for this defense. At trial, he had a
    second chance to make his case for a public authority defense when he testified in
    15
    Case: 13-14843     Date Filed: 12/11/2015    Page: 16 of 46
    his own behalf. The district court concluded, however, that Defendant had still
    failed to provide an evidentiary foundation for the defense. Accordingly, the court
    declined to instruct the jury to consider a public authority defense, but did instruct
    the jury to consider whether Defendant acted with an “innocent intent.” Defendant
    argues that the district court erred in rejecting his proposed instruction on the
    public authority defense.
    A.     Potential Defenses Available to a Defendant Who Alleges
    Authorization of His Criminal Conduct by Law Enforcement
    When a defendant has engaged in criminal conduct at the alleged behest of
    people who identify themselves as law enforcement officers, three defenses are
    potentially available in this Circuit: public authority, entrapment-by-estoppel, and
    innocent intent. Over twenty years ago, we noted “the muddled state of the law in
    this circuit regarding defenses based on perceived governmental authority.”
    United States v. Baptista-Rodriguez, 
    17 F.3d 1354
    , 1368 n.18 (11th Cir. 1994).
    Given the subtle distinctions between the defenses that are available when a known
    governmental actor has allegedly directed a defendant to commit a criminal act, a
    review of these doctrines is a useful way to begin our analysis of the parties’
    respective positions.
    1.     Public Authority
    A defendant may assert a public authority affirmative defense when he has
    knowingly acted in violation of federal criminal law, but has done so in reasonable
    16
    Case: 13-14843     Date Filed: 12/11/2015   Page: 17 of 46
    reliance on the authorization of a governmental official. Id.; see also United States
    v. Reyes-Vasquez, 
    905 F.2d 1497
    , 1500 n.5 (11th Cir. 1990) (a public authority
    defense applies when a defendant alleges that his actions were taken under color of
    public authority). For example, an informant who participates in a typical
    undercover drug sting operation at the behest of the DEA could potentially assert a
    public authority defense were he later to be prosecuted for his participation.
    The public authority defense is narrowly defined, however, and a defendant
    will not be allowed to assert the defense, or to demand that the jury be instructed
    on it, unless he meets certain evidentiary prerequisites. First, as the name of the
    defense implies, a federal law enforcement officer must have actually authorized
    the defendant to commit the particular criminal act at issue, and the defendant must
    have reasonably relied on that authorization when engaging in that conduct.
    United States v. Johnson, 
    139 F.3d 1359
    , 1365–66 (11th Cir. 1998) (public
    authority defense is only available when a defendant can show that he “relied on
    official government communications before acting in a manner proscribed by law,”
    and that this reliance was reasonable).
    Second, the government official on whom the defendant purportedly relied
    must have actually had the authority to permit a cooperating individual to commit
    the criminal act in question. 
    Id. at 1365
    (“The actual authority defense requires
    proof that a defendant reasonably relied upon the actual authority of a government
    17
    Case: 13-14843      Date Filed: 12/11/2015    Page: 18 of 46
    official to request participation in an illegal activity.” (emphasis added)). If,
    contrary to the defendant’s genuine belief, the official possessed no such authority,
    then the public authority defense cannot be asserted. See 
    Baptista-Rodriguez, 17 F.3d at 1368
    n.18 (“[R]eliance on the apparent authority of a government official
    is not a defense in this circuit . . . .”); United States v. Anderson, 
    872 F.2d 1508
    ,
    1516 (11th Cir. 1989) (disallowing defendants’ reliance on apparent authority of
    CIA agent because the latter lacked actual power to authorize violation of laws);
    United States v. Rosenthal, 
    793 F.2d 1214
    , 1236 (11th Cir. 1986), modified on
    other grounds, 
    801 F.2d 378

    2.     Entrapment-by-Estoppel
    Closely related to the public authority defense is the entrapment-by-estoppel
    defense. See United States v. Baker, 
    438 F.3d 749
    , 753 (7th Cir. 2006) (noting the
    similarity of the elements that comprise the two defenses and that some courts have
    treated them as being “synonymous”). In contrast to a public authority defense,
    which potentially protects a defendant who knowingly engages in acts that he
    recognizes to be in violation of the law, an entrapment-by-estoppel defense applies
    to a defendant who reasonably relies on the assurance of a government official that
    specified conduct will not violate the law. 
    Baptista-Rodriguez, 17 F.3d at 1368
    n.18 (entrapment-by-estoppel “applies when a government official tells a
    defendant that certain conduct is legal and the defendant commits what would
    18
    Case: 13-14843     Date Filed: 12/11/2015    Page: 19 of 46
    otherwise be a crime in reasonable reliance on the official’s representation”);
    accord United States v. Strahan, 
    565 F.3d 1047
    , 1051 (7th Cir. 2009) (same);
    United States v. Thompson, 
    25 F.3d 1558
    , 1564 (11th Cir. 1999) (the doctrine
    applies when an official tells a defendant that certain conduct is legal and the
    defendant believes the official); United States v. Hedges, 
    912 F.2d 1397
    , 1405
    (11th Cir. 1990) (equitable estoppel defense applicable where military officer
    relied on advice of counselor, whose job it was to give such advice, as to whether
    his conduct was legal).
    Thus, entrapment-by-estoppel creates a narrow exception to the general rule
    that ignorance of the law is no defense. 
    Thompson, 25 F.3d at 1561
    n.2 (holding
    doctrine to be applicable where an AUSA told a convicted felon that he would be
    immune from prosecution for future possession of a firearm so long as he was
    cooperating with the Government in its investigation). Like the public authority
    defense, entrapment-by-estoppel can apply only when the defendant’s reliance on
    an official’s reassurance is reasonable. 
    Baptista-Rodriguez, 17 F.3d at 1368
    n.18;
    see also United States v. Baker, 
    438 F.3d 749
    , 753 (7th Cir. 2006) (holding that
    entrapment-by-estoppel defense applies when a defendant reasonably believes a
    government official’s assurance that certain conduct is legal); United States v.
    Burrows, 
    36 F.3d 875
    , 882 (9th Cir. 1994) (noting that defendant’s reliance must
    19
    Case: 13-14843     Date Filed: 12/11/2015    Page: 20 of 46
    be reasonable for either a public authority or entrapment-by-estoppel defense to
    apply).
    Also like the public authority defense, entrapment-by-estoppel requires a
    showing that a government official affirmatively communicated to the defendant
    the official’s approval of the conduct at issue. See 
    Johnson, 139 F.3d at 1365
    (both
    entrapment-by-estoppel and public authority defense require reliance on official
    government communications that authorize violation of the law); United States v.
    Pardue, 
    385 F.3d 101
    , 108–09 (1st Cir. 2004) (entrapment-by-estoppel defense
    requires an affirmative representation by a government official that defendant’s
    conduct would be legal).
    The entrapment-by-estoppel defense differs from the public authority
    defense in that the latter requires that the government official who sanctions the
    illegal activity have actual authority to approve the defendant’s criminal activity,
    whereas the entrapment-by-estoppel defense only requires that the official have
    apparent authority. United States v. Stallworth, 
    656 F.3d 721
    , 727 (7th Cir. 2011);
    cf. 
    Hedges, 912 F.2d at 1405
    (defendant was entitled to receive an entrapment-by-
    estoppel jury instruction even though the governmental agent could not actually
    waive or authorize a violation of the statute). And given the practical difficulty in
    the mine-run of cases to draw a meaningful distinction between the culpability of a
    defendant who knows the conduct he has been authorized to commit is illegal
    20
    Case: 13-14843     Date Filed: 12/11/2015    Page: 21 of 46
    (public authority defense) and a defendant who has been assured that the conduct is
    legal (entrapment-by-estoppel defense), it is the public authority defense’s
    requirement of actual authority that creates the most significant demarcation
    between the two defenses. 
    Stallworth, 656 F.3d at 726
    –27.
    That said, not all courts find merit in this dichotomy between actual and
    apparent authority. In particular, the Second Circuit has questioned the wisdom of
    such a distinction, given “that the motivating principle underlying the doctrine is
    ‘the unfairness of prosecuting one who has been led by the conduct of government
    agents to believe his acts were authorized.’” United States v. Giffen, 
    473 F.3d 30
    ,
    42 n.12 (2d Cir. 2006) (quoting United States v. Abcasis, 
    45 F.3d 39
    , 44 (2d Cir.
    1995)). According to the Second Circuit, when an individual is being prosecuted
    for conduct that a government official has solicited, it is just as unfair to hold him
    criminally responsible when an official’s authority was only apparent as it would
    be to do so when that authority was actual. 
    Id. Indeed, because
    most individuals
    are ill-equipped to figure out whether an approving official has actual versus only
    apparent authority, the Giffen court noted its understanding that “the defense of
    entrapment by estoppel in this circuit [applies] to encompass circumstances where
    the defendant reasonably relies on the inducements of government agents who
    have apparent authority to authorize the otherwise criminal acts—even if they do
    not in fact possess such authority.” 
    Id. 21 Case:
    13-14843        Date Filed: 12/11/2015   Page: 22 of 46
    In any event, the actual authority of the supervising agents here to authorize
    Defendant’s conduct is undisputed and Defendant no longer argues on appeal that
    he was entitled to an entrapment-by-estoppel defense. Accordingly, we need not
    address the merits of the actual/apparent authority distinction, nor linger any
    further in our examination of the entrapment-by-estoppel defense.
    3.    Innocent Intent
    As noted, the district court instructed the jury that it should acquit Defendant
    if it found that he acted with an innocent intent during the sixteen months he
    participated in the charged drug conspiracy. Unlike public authority and
    entrapment-by-estoppel, which are affirmative defenses, an innocent intent theory
    is a “defense strategy aimed at negating the mens rea for the crime.” Baptista-
    
    Rodriguez, 17 F.3d at 1368
    n.18. Utilizing this “defense tack” in cases involving
    “perceived governmental authority,” the defendant may argue his innocent intent
    as a means to persuade the jury that the prosecution has not met its burden of
    proving his criminal intent. 
    Id. Thus in
    a case such as this, where a defendant is found not to have met the
    requirements necessary for a public authority defense, he can nonetheless
    effectively backdoor the rejected defense by testifying that he genuinely believed
    that the criminal acts he performed were done at the direction, and with the
    permission, of an appropriate governmental agency. Armed with that testimony,
    22
    Case: 13-14843     Date Filed: 12/11/2015    Page: 23 of 46
    his attorney can then argue to the jury that the defendant lacked criminal intent
    and, if the jury accepts that argument, it can then properly return a verdict of not
    guilty. 
    Id. Indeed, because
    this defense strategy works to negate a required
    element of the offense that the Government must prove beyond a reasonable doubt,
    a defendant need only raise a reasonable doubt as to whether he possessed the
    necessary criminal intent. See 
    Anderson, 872 F.2d at 1517
    –18 & n.14 (affirming
    jury instruction that defendants should be exonerated if jury had “a reasonable
    doubt [as to] whether the defendants acted in good faith[,] sincere[ly] believ[ing]
    that their activity was exempt by the law”).
    Our Circuit has now, for three decades and in several cases, affirmed the
    viability of this innocent intent “defense” in cases where the defendant argues that
    his criminal acts were undertaken as part of his cooperation with the Government.
    See, e.g., United States v. Juan, 
    776 F.2d 256
    , 257–58 (11th Cir. 1985) (vacating
    conditional plea of guilty to “drug offenses” where defendant had argued that he
    lacked criminal intent because he thought he was acting in cooperation with the
    Government, but district court disallowed defendant access to evidence relevant to
    support his claim of “innocent intent”); 
    Baptista-Rodriguez, 17 F.3d at 1363
    , 1368
    & n.18 (reversing conviction for conspiracy to import cocaine, where defendant
    testified that he “believed he was working as an authorized undercover civilian
    operative when he arranged the smuggling venture,” because district court
    23
    Case: 13-14843       Date Filed: 12/11/2015      Page: 24 of 46
    improperly limited cross-examination of FBI agent that would have shored up
    defendant’s argument that he “lacked the requisite mens rea for the crimes:
    specific intent to violate the law”); United States v. Ruiz, 
    59 F.3d 1151
    , 1154–55
    (11th Cir. 1995) (reversing a conviction for conspiracy to distribute drugs because
    a general willfulness instruction was inadequate to address defendant’s valid
    theory of defense, which was her genuine belief that she was performing legitimate
    law enforcement activities, and the district court should instead have given a
    willfulness instruction that was better tailored to defendant’s testimony); United
    States v. Grajales, 450 F. App’x 893, 900–01 (11th Cir. 2012)8 (reversing drug
    conspiracy and robbery convictions where defendant testified that he genuinely,
    albeit mistakenly, believed he was working with law enforcement, but district court
    did not give a proper instruction concerning innocent intent).
    Yet, in recognizing the availability of an innocent intent theory of defense
    for a defendant who has failed to meet the standard for a public authority
    affirmative defense, we acknowledge that our Circuit may be the only circuit to
    explicitly allow an innocent intent defense in this context. Or at least that’s what
    the Second Circuit observed in United States v. Giffen, 
    473 F.3d 30
    (2d Cir. 2006).
    In rejecting the defendant’s public authority and entrapment-by-estoppel defenses,
    8
    Aware that our non-published decisions carry no precedential weight, see 11th Cir. R. 36-2, we
    do not rely on or endorse the reasoning or holding in Grajales, but instead cite it only to show
    that the “innocent intent” theory of defense is not a relic of the past in this Circuit.
    24
    Case: 13-14843       Date Filed: 12/11/2015       Page: 25 of 46
    that court turned to the innocent intent “defense”—which it described as “negation
    of intent”—and remarked that “[s]uch a legal theory . . . has been expressly
    recognized only in the Eleventh Circuit.” 
    Id. at 43.
    While not firmly deciding
    whether it might ever find a circumstance that would justify allowing a defendant
    who could not show public authority to nonetheless articulate, as a theory of
    defense, that he “honestly, albeit mistakenly, believed he was committing the
    charged crimes in cooperation with the government,” the court acknowledged that
    it had “great difficulty with this proposition, which would swallow the actual
    public authority and entrapment-by-estoppel defenses.” Id.; see also United States
    v. Wilson, 
    721 F.2d 967
    , 975 (4th Cir. 1983) (“Such an unwarranted extension of
    the good faith defense would grant any criminal carte blanche to violate the law
    should he subjectively decide that he serves the government’s interests thereby.
    Law-breakers would become their own judges and juries.”). 9
    We are not called on in this case to reexamine the merits of the “innocent
    intent” theory of defense. The district court gave that instruction at the request of
    Defendant. The Government has not cross-appealed on this ground. And even if
    this issue were squarely before us, we would nonetheless be obliged to follow our
    9
    The Fourth Circuit later, however, recognized a version of this theory of defense, but only
    where the government official possesses actual authority. See United States v. Fulcher, 
    250 F.3d 244
    , 252–53 (4th Cir. 2001) (holding that criminal intent is negated only if “(1) the defendant
    honestly believed that he was acting in cooperation with the government, and (2) the government
    official [] upon whose authority the defendant relied possessed actual authority to authorize his
    otherwise criminal acts”).
    25
    Case: 13-14843       Date Filed: 12/11/2015       Page: 26 of 46
    binding precedent. See United States v. Vega-Castillo, 
    540 F.3d 1235
    , 1236 (11th
    Cir. 2008) (the prior-precedent rule requires that we follow a prior binding
    precedent “unless and until it is overruled by this court en banc or by the Supreme
    Court”).
    But as Defendant’s primary complaint on appeal is the district court’s failure
    to instruct the jury on his public authority defense, the fact that he received an
    instruction that was arguably more helpful, and that might well have been
    disallowed in other circuits, should provide him some perspective, if not solace.
    And it is to the omitted public authority instruction that we now turn.
    B.      District Court’s Refusal to Give a Public Authority Defense
    Instruction
    1.     Absence of Evidentiary Support for Defense
    In an effort to distill the essence of what is a confusing argument by
    Defendant on this issue, we infer his contention to be that he offered sufficient
    evidence to support a public authority defense and therefore the district court erred
    when it refused to instruct the jury to consider this defense.10 We review a district
    10
    Defendant articulated this issue differently in his opening brief. There he argues that the
    district court erred by adopting the magistrate judge’s recommendation that Defendant be
    precluded from asserting a public authority defense. But because Defendant produced no
    testimony at the pretrial hearing—not even his own—to show that he had been authorized by
    agents to engage in the criminal conspiracy for which he was indicted, the magistrate judge had
    no basis to conclude anything but that Defendant had failed to offer evidence of authorization by
    government agents.
    26
    Case: 13-14843        Date Filed: 12/11/2015        Page: 27 of 46
    court’s refusal to give a requested jury instruction for abuse of discretion. United
    States v. Svete, 
    556 F.3d 1157
    , 1161 (11th Cir. 2009) (en banc). Further, when the
    defendant seeks an instruction on a proposed defense that contains multiple
    elements, as affirmative defenses often do, the defendant must proffer evidence
    that supports each element. United States v. Flores, 
    572 F.3d 1254
    , 1266 (11th
    Cir. 2009); United States v. Montgomery, 
    772 F.2d 733
    , 736 (11th Cir. 1985);
    United States v. Gant, 
    691 F.2d 1159
    , 1165 (5th Cir. 1982). In evaluating a
    defendant’s evidentiary proffer, a court considers the evidence in the light most
    favorable to the defendant. United States v. Hedges, 
    912 F.2d 1397
    , 1405–06
    (11th Cir. 1990).
    But as to the amount of evidence that a defendant must first produce in order
    to receive an instruction on his proposed defense, our precedent has not been
    consistent in its description of that standard. On the one hand, there is caselaw
    This pretrial hearing did not end Defendant’s efforts to present the defense, however. He
    testified at length at trial as to his interactions with the agents and as to his belief that he was
    authorized by the agents to engage in the sixteen-month conspiracy for which he was being tried.
    So, contrary to his argument, Defendant was allowed, through his own testimony, to present
    evidence in support of a public authority defense at trial. What he was not allowed to do,
    however, was have the jury consider that defense because, having heard his testimony, the
    district court did not alter its conclusion that Defendant had failed to show a basis for the
    defense.
    Defendant did ask the district court whether it would be willing to instruct the jury on the public
    authority defense in light of his testimony, which request the court denied. Thus,
    notwithstanding Defendant’s characterization of his argument, we nonetheless review what we
    perceive to be the essence of his complaint: the failure of the district court to instruct the jury on
    the public authority defense.
    27
    Case: 13-14843     Date Filed: 12/11/2015    Page: 28 of 46
    indicating that a defendant is entitled to an instruction on an affirmative defense
    when, taking the evidence in the light most favorable to him, “there exists evidence
    sufficient for a reasonable jury to find in his favor” on that defense. Mathews v.
    United States, 
    485 U.S. 58
    , 63 (1988); accord United States v. Gutierrez, 
    745 F.3d 463
    , 472 (11th Cir. 2014) (addressing affirmative defense of self-defense). Thus,
    under this line of authority, when pursuing an affirmative defense that sets out a
    multi-part test, the defendant must have offered evidence sufficient to prove each
    element of that defense. See 
    Flores, 572 F.3d at 1266
    (where the defendant failed
    to offer evidence sufficient to prove each element of the defense, district court
    properly refused to instruct jury on affirmative defense of justification);
    
    Montgomery, 772 F.2d at 736
    (because a defendant must first produce sufficient
    evidence to prove the essential elements of an affirmative defense and defendant
    failed to do so, the district court properly disallowed affirmative defense of
    necessity). See also United States v. Baker, 
    438 F.3d 749
    , 753 (7th Cir. 2006)
    (holding that a court may preclude an affirmative defense when the court accepts
    as true the evidence proffered by the defendant, but finds this evidence to be
    insufficient as a matter of law to support the affirmative defense).
    On the other hand, we have also described the standard as requiring an
    instruction if there is “any foundation” in the evidence. 
    Hedges, 912 F.2d at 1406
    .
    Accord United States v. Arias, 
    431 F.3d 1327
    , 1340 (11th Cir. 2005); United States
    28
    Case: 13-14843     Date Filed: 12/11/2015   Page: 29 of 46
    v. Ruiz, 
    59 F.3d 1151
    , 1154 (11th Cir. 1995); United States v. Lively, 
    803 F.2d 1124
    , 1126 (11th Cir. 1986) (quoting United States v. Young, 
    464 F.2d 160
    , 164
    (5th Cir. 1972)). And sometimes we have articulated both standards in the same
    opinion. See, e.g., United States v. Middleton, 
    690 F.2d 820
    , 826 (11th Cir. 1982)
    (noting that a defendant who has produced “some evidence” should receive an
    instruction on his proposed defense, but also quoting with approval language
    indicating that the proffered evidence must be “legally sufficient to render the
    accused innocent”) (quoting Strauss v. United States, 
    376 F.2d 416
    , 419 (5th Cir.
    1967)).
    Even if we assume some tension between these two standards and also
    assume that the “any foundation/some evidence” iteration poses an easier test for a
    defendant to meet, there is no need to try to harmonize those standards in this case.
    Because Defendant failed to offer any evidence that a law enforcement official
    authorized his criminal conduct, he failed to meet either standard: meaning that he
    was not entitled to a jury instruction concerning the public authority defense.
    As explained above, a defendant who seeks an instruction on a public
    authority defense must produce evidence that (1) a government official authorized
    him to take what would otherwise be an illegal action; (2) that this official had the
    actual authority to permit the action; and (3) that the defendant reasonably relied
    on the official’s authorization. There is no dispute here that the controlling agents
    29
    Case: 13-14843    Date Filed: 12/11/2015    Page: 30 of 46
    with whom Defendant worked had the authority to approve his participation in the
    undercover drug conspiracy that was charged in the present indictment. There are
    few disputes, and none of them material, between the agents and Defendant as to
    their communications. Yet, taking the evidence in the light most favorable to
    Defendant, which means taking as true his testimony, we agree with the district
    court that Defendant failed to provide evidence that the agents had ever authorized
    him to participate in the sixteen-month conspiracy that led to his indictment.
    Indeed, the vagueness and generality of Defendant’s testimony, by itself, reinforces
    a conclusion that he simply lacks any evidence to support an argument that
    supervising agents had authorized his activities, or that he could have reasonably
    understood them to have done so.
    Recapping our earlier summary of the evidence, for about a six-month
    period of time, between August 2008 and March 2009, Defendant acted as an
    informant under the supervision of DEA agents in Central and South America who
    were trying to uncover illegal drug importation activity. Formalizing his
    relationship with the agents, Defendant signed written agreements which provided
    that he was immune from prosecution only for activities specifically authorized by
    his controlling agents and that he agreed to take no independent action on behalf of
    American law enforcement interests without such authorization.
    30
    Case: 13-14843     Date Filed: 12/11/2015    Page: 31 of 46
    As to this drug investigation, neither Defendant nor the two testifying
    agents, Ball and Romain, offered much detail as to exactly what assistance he
    provided, nor did they give much information about the number or nature of
    interactions between them. What we do know from the evidence presented is that
    in January 2009, Agent Romain had essentially told Defendant that their working
    relationship was over. Defendant himself admitted that Agent Romain had told
    him to “fruck off” and leave Colombia as soon as possible because “you guys
    didn’t want to work with me” anymore.
    Defendant did not leave Colombia. And, notwithstanding this seemingly
    unambiguous message from Agent Romain that Defendant’s services as an
    informant were no longer wanted or needed, Defendant nonetheless claims that he
    believed he was working on behalf of the DEA agents over the next sixteen
    months, albeit without their knowledge, and that he believed his activities to be
    authorized by the agency. Yet, at no time during this sixteen-month period did
    Defendant make any effort to let these agents know what he was accomplishing as
    their informant. Which is too bad, because Defendant had a lot to tell. Indeed,
    taking Defendant at his word that, at least in his own mind, he was continuing to
    function as an informant while in the thick of drug activity that would have
    obviously intrigued the agents, his silence is inexplicable. By at least the spring of
    2009, Defendant was having conversations with his soon-to-be co-conspirators
    31
    Case: 13-14843     Date Filed: 12/11/2015   Page: 32 of 46
    about involving himself in their drug dealing. And in June 2009, Defendant met
    with the purported commander of an illegal paramilitary group and discussed the
    latter’s willingness to provide Defendant large quantities of drugs in return for
    Defendant’s sale of grenade launchers, surface-to-air missiles, and other weapons.
    Surely, Defendant realized that the agents would be keenly interested in this
    development so that they could deploy standard investigative techniques, such as
    the interception of telephone calls and visual monitoring, to build their case. Yet
    again, Defendant said nothing. Further, over the entirety of the charged
    conspiracy, Defendant was involved in other drug-related endeavors with McField-
    Bent and Archibold—two individuals in whose activities he knew the agents to be
    interested—with one of their drug shipments having been seized by Colombian
    authorities. But again, radio silence from Defendant. Finally, in May 2010,
    Defendant was kidnapped by a drug cartel and held for three days before escaping:
    a dramatic event about which his handlers would surely want to be informed. Yet
    once again, Defendant kept this news to himself. In short, Defendant participated
    in numerous acts in furtherance of the criminal conspiracy, including telephone
    calls, meetings, money transfers, and drug deals. Yet, he told his former
    supervising agents nothing about any of these events.
    In fact, Defendant agrees that none of the criminal acts he committed during
    the sixteen-month term of the conspiracy was explicitly authorized by the agents.

    How could they have been, given Defendant’s failure to ever inform the agents of
    what he was doing? He also acknowledges, as he must, that his written agreements
    with the agencies prohibited him from taking any actions not authorized by his
    handlers. His only explanation for his violation of the agreements’ requirement
    that he only undertake illegal activity that was approved by the agents was to
    recount Agent Romain’s alleged statement, in an undescribed context, that the
    written documents were “merely formalities.” In addition, Defendant testified that
    he did not think he needed to inform the agents what he was doing because they
    had earlier told him that they had the technological capabilities to listen in to all his
    telephone calls and to discern, through GPS, where he was at all times. 11 So,
    according to Defendant, he inferred that the agents knew everything he was doing
    and, by their silence, he assumed they necessarily had approved his actions.
    Finally, Defendant claims that because he had never been formally deactivated by
    the agents, he could still consider himself an informant. He makes this claim
    notwithstanding having been told that the agents no longer wanted to work with
    him, notwithstanding the absence of any request by agents for his assistance during
    the period of the conspiracy, and notwithstanding his awareness that the written
    11
    Agent Romain denied informing Defendant that the agreements were “mere formalities” or
    that the DEA at all times was able to listen in to his telephone calls or know his geographical
    positioning. But we take the facts in the light most favorable to Defendant and assume his
    version of events. 
    Hedges, 912 F.2d at 1406
    .
    33
    Case: 13-14843     Date Filed: 12/11/2015    Page: 34 of 46
    agreements between him and the agency had expired during the beginning of the
    sixteen-month period described in the indictment.
    Defendant’s argument can be boiled down to the following: up until the
    time an informant is formally deactivated, any criminal conduct he engages in is
    deemed to be authorized by the law enforcement agency, even if agents have no
    knowledge of the informant’s actions, so long as the informant (1) believes that his
    status as an informant relieves him of the obligation to obtain approval for his
    chosen actions or (2) assumes that the agency has probably learned elsewhere
    about his criminal conduct, and infers authorization from the agency’s subsequent
    silence.
    Of course, what is lacking in Defendant’s interpretation of the term
    “authorization” is anything remotely approaching the definition that is actually
    applied to that word. Black’s Law Dictionary defines the word “authorize” as
    meaning, “To formally approve; to sanction .” BLACK’S LAW DICTIONARY (10th ed. 2015). The phrase “authorization
    of an action” connotes first, an awareness of the intended action by the person
    authorizing it and second, a communication to the person undertaking the action.
    An assumption that one is not required to obtain approval or that the approving
    official may well know of the intended action is not the same thing as having
    gotten authorization to take the action. And it is the actual affirmative
    34
    Case: 13-14843     Date Filed: 12/11/2015   Page: 35 of 46
    communication by a law enforcement agent that transforms an informant’s
    assumption of authorization into the approval that is required for the public
    authority defense to apply.
    We are aware of no caselaw that supports an interpretation that so turns on
    its head the word “authorize.” The sparse authority in analogous cases that we
    have found surely does not support Defendant’s peculiar interpretation. See United
    States v. Mergen, 
    764 F.3d 199
    , 205 (2d Cir. 2014) (For the public authority
    defense to apply, the defendant must “in fact” have been authorized by the
    Government to engage in what would otherwise be illegal activity. Thus, the fact
    that defendant was acting as an informant on other matters for the FBI and had
    even brought to its attention a planned arson did not confer on him the
    authorization of the Bureau to participate in that arson); 
    Giffen, 473 F.3d at 41
    (where official encouraged defendant to continue with his informant activities, the
    former had not authorized the defendant to commit illegal conduct not mentioned
    in the previous disclosures); 
    Abcasis, 45 F.3d at 43
    –44 (public authority defense
    will not “support a claim of an open-ended license to commit crimes in the
    expectation of receiving subsequent authorization”); cf. United States v. Goodwin,
    
    496 F.3d 636
    , 644 (7th Cir. 2007) (reiterating district court’s conclusion that
    defendant was not entitled to assert a public authority defense because he “was
    attempting to play both sides of the street” when “engaged in freelance drug
    35
    Case: 13-14843       Date Filed: 12/11/2015       Page: 36 of 46
    dealing distinct from the controlled deals that he made at the government’s
    instruction as a then-confidential informant”).
    In short, Defendant’s proffered evidence is little more than a recitation of his
    purported, and rather convenient, assumptions, not proof of authorization by the
    supervising agents. In reaching this conclusion, however, we caution that
    adherence to formalistic requirements is not a prerequisite to a finding of approval
    by the appropriate official. For example, had the DEA agents here verbally
    approved of Defendant’s participation in the criminal conspiracy, the fact that the
    confidential informant’s agreement had already expired or that a new written
    document had not been issued would not necessarily preclude a finding that
    authorization had been given. Likewise, we are not holding that, in every case,
    authorization must be so specific that an informant will be required to seek out and
    receive instruction for each discrete act that he takes.12 Further, a course of
    conduct between the agents and the informant and the latter’s reasonable reliance
    on past communications may, in appropriate circumstances, give rise to an
    inference of authorization.
    12
    A controlling agent will typically direct an informant to report back immediately if he
    becomes compelled, in an undercover situation, to deviate from the script and take actions not
    envisioned during preparatory conversations with the agent. We will assume that a short period
    of delay in reporting back to the agent, if reasonably necessitated by the exigencies of the
    situation, would not compromise an informant’s ability to later claim a public authority defense.
    Here, however, Defendant has offered no explanation why, if he was truly functioning as an
    informant, he was unable to report this fact to the supervising agents during the sixteen-month
    period in which this conspiracy operated.
    36
    Case: 13-14843     Date Filed: 12/11/2015     Page: 37 of 46
    In sum, for us to infer authorization of a particular action, the
    communications and course of dealing between an informant and his supervising
    agents must be such that the informant would reasonably understand he is
    authorized to engage in the particular conduct at issue. And his conduct “must
    remain within the general scope of the solicitation or assurance of authorization.”
    
    Abcasis, 45 F.3d at 43
    –44. This means that “[w]hether a defendant was given
    governmental authorization to do otherwise illegal acts through some dialogue
    with government officials necessarily depends, at least in part, on precisely what
    was said in the exchange.” 
    Giffen, 473 F.3d at 39
    ; cf. United States v. Burt, 
    410 F.3d 1100
    , 1104 (9th Cir. 2005) (finding that defendant was entitled to a public
    authority instruction where she testified that federal agents gave her no instructions
    as to how to conduct herself and told her that as long as she was gathering
    information for them, her actions would not be illegal).
    Here, though, a conclusion that Defendant lacked authorization to engage in
    this sixteen-month criminal conspiracy is not a close call. And absent such
    authorization, Defendant had no entitlement to violate the law with impunity nor
    any right to a public authority instruction that would vindicate that claimed
    expectation. Accordingly, we conclude that the district court did not err in refusing
    to instruct the jury to consider whether Defendant had acted under public authority
    in committing his offense.
    37
    Case: 13-14843     Date Filed: 12/11/2015    Page: 38 of 46
    2.     Defendant Was Not Harmed by the Absence of a Public
    Authority Instruction
    Had Defendant offered sufficient evidence to warrant a public authority
    instruction, the district court, of course, should have given the instruction. But in
    any event, we can find no harm to Defendant as a result of the court’s failure to
    offer this additional instruction because the jury’s obvious rejection of Defendant’s
    claimed “innocent intent” would have similarly doomed his chance of success on a
    public authority defense.
    Specifically, the court instructed the jury that the Government had the
    burden of proving Defendant’s guilt beyond a reasonable doubt. It also told the
    jury that, in order to convict Defendant, it would have to find that he “willfully
    joined in the charged conspiracy with the intent to do something the law forbids.”
    Further, it defined the word “willful” for the jury: “The word ‘willfully’ means
    that the act was committed voluntarily and purposely, with the intent to do
    something the law forbids, that is, with the bad purpose to disobey or disregard the
    law.” Finally, the court outlined to the jury Defendant’s theory of defense, which
    was that Defendant honestly believed he was performing the charged conduct to
    help law enforcement. The court emphasized to the jury that it was not
    Defendant’s obligation to prove his honest belief because he had no burden to
    prove anything. It ended this instruction by advising the jury that if it concluded
    38
    Case: 13-14843        Date Filed: 12/11/2015      Page: 39 of 46
    Defendant honestly believed that he was working to help law enforcement, the jury
    should find him not guilty. 13
    In short, according to the court’s “innocent intent” instruction, Defendant
    had no burden of proving his honest belief that he was not acting contrary to the
    law, but instead the Government had the burden of proving beyond a reasonable
    doubt his willfulness. Yet, by finding Defendant guilty, the jury clearly
    communicated its disbelief of Defendant’s testimony that he was merely
    functioning as a DEA informant throughout the sixteen months that he participated
    in the charged drug importation conspiracy. We know this to be so because the
    court instructed the jury that it should acquit Defendant if it concluded that he
    engaged in his conspiratorial conduct out of an honest belief that he was helping
    the Government in its investigation. As the only evidence supporting a claim of
    honest belief was Defendant’s testimony, the jury clearly did not buy his story.
    See United States v. Joseph, 
    709 F.3d 1082
    , 1103 (11th Cir. 2013) (a defendant’s
    testimony denying the required “mens rea can . . . be fatal to his attempt to
    exculpate himself” because, if disbelieved by the jury, that testimony can itself “be
    used as substantive evidence of guilt” (internal citations omitted)).
    13
    “The crime charged requires a finding that the Defendant willfully joined in the charged
    conspiracy with the intent to do something the law forbids. It is the Defendant’s theory of
    defense that he honestly believed that he was performing the conduct with which he is charged to
    help law enforcement. The burden of proof is not on the Defendant to prove his honest belief
    since he has no burden to prove anything. If you find that the Defendant had the honestly held
    belief that he was performing the conduct with which he is charged to help law enforcement,
    then you should return a verdict of not guilty.” (emphasis added).
    39
    Case: 13-14843     Date Filed: 12/11/2015   Page: 40 of 46
    And if the jury rejected Defendant’s claim that he believed himself to be
    merely acting on behalf of the DEA during the sixteen months in which he was
    giving every indication of being a bona fide drug dealer, then the jury also would
    have necessarily rejected a public authority defense because the latter is available
    only to a defendant who reasonably relies on a federal agent’s authorization to
    commit a crime. If, as the jury concluded, Defendant did not honestly believe that
    he was acting to assist governmental investigators, then necessarily he could not
    have been relying on any perceived authorization, which is required for the public
    authority defense.
    Moreover, while an “innocent intent” theory of defense does not require that
    the defendant demonstrate that his “honest belief” was reasonable, a public
    authority defense does. See supra at 17–19, 23–27. Having received a helpful
    instruction that allowed an acquittal based on an honest, albeit possibly
    unreasonable, belief, it is hard to see how Defendant would have been helped by a
    competing public authority defense that informed the jury that this very same
    belief had to be reasonable.
    3.      District Court Did Not Err in Modifying Defendant’s Requested
    Innocent Intent Instruction
    Finally, Defendant makes one last argument concerning the instructions. He
    complains that immediately prior to instructing the jury on the significance of
    Defendant’s “honest belief,” the court clarified for the jury that Defendant had not
    40
    Case: 13-14843      Date Filed: 12/11/2015    Page: 41 of 46
    actually been authorized by law enforcement officers to perform the acts with
    which he was charged. Other than expressing unhappiness with this clarification,
    Defendant offers little in the way of analysis as to how the court erred by making
    the statement. He simply repeats his argument that the court should have given a
    public authority defense and states that the above language directed a verdict for
    the Government. We find neither argument to be persuasive.
    This Court reviews the legal correctness of jury instructions de novo but
    “defer[s] on questions of phrasing absent an abuse of discretion.” United States v.
    Prather, 
    205 F.3d 1265
    , 1270 (11th Cir. 2000). District courts have broad
    discretion in formulating jury instructions as long as the whole charge accurately
    reflects the law and facts. Id.; see also Humphrey v. Staszak, 
    148 F.3d 719
    , 723
    (7th Cir. 1998) (an appellate court should reverse only if, “considering the
    instructions, the evidence and the arguments, it appears that the jury was misled
    and its understanding of the issues was seriously affected to the prejudice of the
    complaining party”); United States v. White, 
    552 F.3d 240
    , 246 (2d Cir. 2009) (to
    obtain a reversal on a jury instruction, “a defendant must demonstrate both error
    and ensuing prejudice” and reversal will “occur only where the charge, viewed as a
    whole, either failed to inform the jury adequately of the law or misled the jury
    about the correct legal rule” (internal citations omitted)).
    41
    Case: 13-14843    Date Filed: 12/11/2015    Page: 42 of 46
    Here, after considering Defendant’s testimony, the court correctly concluded
    that Defendant had failed to present any evidence that federal law enforcement
    officers had authorized him to engage in the drug and weapons trafficking
    conspiracy with which he had been charged. Moreover, the court had become
    concerned at the possible “blurring of the issues” between the intent-negation
    defense theory and the affirmative public authority defense, with Defendant
    attempting to “backdoor the public authority defense” in his efforts to establish his
    lack of intent. Thus, the court concluded that to avoid confusion by the jury, it was
    important to make clear what was at issue (the factual question whether Defendant
    honestly believed he was acting in conformity with his duties as an informant) and
    what was not at issue (the legal question whether, on undisputed facts, federal
    agents could be said to have authorized Defendant to engage in the acts which he
    undertook).
    Clarity is a virtue in jury instructions. “The whole purpose of the charge is
    to enlighten the minds of the jurors with reference to the law arising out of the
    issues and the evidence so that they may intelligently arrive at their verdict.”
    United States v. Hill, 
    417 F.2d 279
    , 281–82 (5th Cir. 1969). Here, the judge’s
    preface to the “innocent intent” instruction and that instruction, itself, made clear
    to the jury the factual matter that they were expected to decide and the legal
    question that was not before them. The information conveyed to the jury in the
    42
    Case: 13-14843        Date Filed: 12/11/2015        Page: 43 of 46
    instruction was accurate. Moreover, while it is true that a court directs a verdict
    when it decides for the jury an “ultimate question of fact as to an essential
    element” of the charged crime, United States v. Howard, 
    855 F.2d 832
    , 835 (11th
    Cir. 1988), the court here did not intrude itself into any resolution of a fact or an
    element of the offense. To the contrary, the question whether federal agents had
    authorized Defendant’s actions went, not to an element, but to whether Defendant
    would be allowed to present an affirmative defense. It would have been improper
    and confusing for the jury to have accidentally stumbled into public-authority-
    defense territory in its deliberations without a full instruction as to what that
    defense entailed, and when Defendant had not met the standards for that defense.
    See 
    Anton, 546 F.3d at 1357
    (a court properly bars a defense when a defendant has
    presented insufficient relevant evidence to support that defense). Finally, for the
    reasons explained above, Defendant suffered no prejudice from the court’s
    prefatory remark. 14
    14
    We likewise find no merit in Defendant’s contention that the district court abused its
    discretion by excluding proposed expert testimony that the supervising DEA agents did not
    follow DEA’s “best practices” in their handling of Defendant. The issue before the jury
    concerned whether Defendant honestly believed that he was acting on behalf of the DEA while
    he was participating in the charged conspiracy. We agree with the Government’s argument that
    testimony concerning the agents’ compliance with agency best practices was not relevant to any
    issue at trial, as required by Federal Rule of Evidence 401, and would have potentially misled the
    jury, wasted time, and caused undue delay, in violation of Federal Rule of Evidence 403. See
    United States v. Wilk, 
    572 F.3d 1229
    , 1235 (11th Cir. 2009) (where defendant relied on a theory
    of self-defense in his prosecution for shooting of police officers, district court properly excluded
    expert testimony that officers’ entry into defendant’s home violated police procedures because it
    43
    Case: 13-14843       Date Filed: 12/11/2015       Page: 44 of 46
    II.    Sentencing Issues
    Under 21 U.S.C. § 960(b)(1)(B)(ii), Defendant’s minimum term of
    imprisonment was ten years and the maximum was life. His offense level under
    the Sentencing Guidelines was 38, with a criminal history category of I, which
    yielded an advisory sentencing range of 292 to 365 months’ imprisonment. The
    district court sentenced Defendant to 360 months’ imprisonment to be followed by
    five years’ supervised release.
    Acknowledging that the Guidelines were correctly calculated and that the
    court sentenced him within the advisory range set therein, Defendant argues that
    his sentence was substantively unreasonable. He argues that the district court
    should have either varied and imposed a sentence below the advisory range or it
    should have imposed a sentence at the low-end of the Guidelines range.
    This Court reviews the reasonableness of a sentence under a deferential
    abuse of discretion standard. Gall v. United States, 
    552 U.S. 38
    , 41 (2007). We
    consider whether the sentence was substantively reasonable in light of the totality
    of the circumstances. 
    Id. at 51.
    The party who challenges the sentence bears the
    burden of showing that it is unreasonable in light of the record and the § 3553(a)
    was defendant’s perception, not the officers’ compliance with procedure, that was relevant in
    determining self-defense).
    44
    Case: 13-14843        Date Filed: 12/11/2015        Page: 45 of 46
    factors. 15 United States v. Tome, 
    611 F.3d 1371
    , 1378 (11th Cir. 2010). The
    weight accorded to any given § 3553(a) factor is a matter within the district court’s
    discretion, and this Court will not substitute its judgment in weighing the relevant
    factors. United States v. Amedeo, 
    487 F.3d 823
    , 832 (11th Cir. 2007). Although
    this Court does not automatically presume a sentence falling within the Guidelines
    range to be reasonable, it ordinarily expects such a sentence to be reasonable.
    United States v. Hunt, 
    526 F.3d 739
    , 746 (11th Cir. 2008).
    Defendant has failed to show that his sentence is substantively unreasonable
    in light of the record and the § 3553(a) factors. See 
    Tome, 611 F.3d at 1378
    . As to
    Defendant’s argument that his sentence is unreasonable because it greatly
    exceeded that of his co-defendants, we note that both defendants confessed their
    guilt and accepted responsibility. Defendant McField-Bent also cooperated with
    the Government and testified at Defendant’s trial. In contrast, as the district court
    noted:
    [Defendant] put on a very elaborate defense that was an effort to
    obfuscate the truth from the jury. The jury could have easily been
    misled. That defense included his own testimony to the jury that
    tried to confuse his past association with DEA and his – what was his
    present involvement, criminal activity, without the DEA’s
    knowledge.
    15
    Those factors include: (1) the nature and circumstances of the offense, (2) the history and
    characteristics of the defendant, (3) the need for the sentence imposed to reflect the seriousness
    of the offense, promote respect for the law, and provide just punishment, and (4) the need to
    protect the public from the defendant. 18 U.S.C. § 3553(a)(1)–(2).
    45
    Case: 13-14843     Date Filed: 12/11/2015   Page: 46 of 46
    In short, we do not find Defendant’s sentence to be unreasonable based on
    its comparative severity in relation to the sentences of his co-defendants or based
    on any other arguments Defendant has made. See United States v. Langston, 
    590 F.3d 1226
    , 1237 (11th Cir. 2009) (holding that no unwarranted disparity resulted
    where the defendant, who proceeded to trial, received longer sentence than a co-
    defendant who pled guilty and cooperated with the government).
    CONCLUSION
    For all the above reasons, we affirm Defendant’s conviction and sentence.
    AFFIRMED.
