    OPINION OF THE COURT
    _____________
    RENDELL, Circuit Judge.
    This case requires us to consider whether, by including
    “without just cause or excuse” in the federal assault with a
    dangerous weapon statute, 
    18 U.S.C. § 113
    (a)(3), Congress
    intended to convert justification, ordinarily a common-law
    defense, into an element of the offense as to which the
    government bears the burden of proof beyond a reasonable
    doubt. Applying relevant Supreme Court precedent, we
    conclude that the existence of just cause or excuse is an
    affirmative defense to a § 113(a)(3) violation, and the
    defendant bears the burden of proving it by a preponderance
    of the evidence. Taylor also raises two issues relating to his
    testimony and offers of proof regarding justification for the
    assault and complains that he was selectively prosecuted. We
    conclude, however, that none of those arguments has merit.
    We will affirm the judgment of the District Court.

    I.
    A. Factual Background
    In the fall of 2006, defendant Aaron Taylor, who had
    been convicted of drug and weapons charges, was an inmate
    at the Federal Detention Center (FDC) in Philadelphia.
    Because of some prior disciplinary violations, including
    previous prison assaults, Taylor was assigned to the Special
    Housing Unit (SHU), separate from the general prison
    population.
    Prisoners in the SHU are allowed one hour of
    recreation a day, five days a week, in a fifteen-by-fifteen foot
    yard. Before each session, a guard asks every inmate whether
    he would like to take or decline recreation. Two guards then
    handcuff each inmate who desires recreation and transport
    him to one of five enclosed yards. After the inmate enters the
    yard, he turns his back to the locked door and places his
    cuffed hands into a slot (also called a “wicket”) so the guards
    on the other side of the door can uncuff him. The same
    process occurs at the end of the hour: one at a time, the
    inmates back up to the wicket so the guards can handcuff
    them. Once all of the inmates have been handcuffed, the
    guards unlock the door and transport the inmates back to their
    cells. According to a prison guard who testified at Taylor‟s
    trial, an inmate may decline recreation, and be returned to his
    cell, at any time during the hour.
    According to Taylor, racial tensions at the FDC were
    inflamed in September 2006 when a white, female
    psychiatrist told Taylor, who is black, to stop looking at her.
    Wayne Maruzin, a white inmate, overheard the exchange and,
    according to Taylor, later discussed the incident with Peter
    3
    Bistrian, another white inmate. Bistrian then threatened
    Taylor. About a week later, Taylor filed a complaint with the
    warden asserting that the psychiatrist‟s comments were
    racially motivated and exacerbated racial tension among the
    inmates.
    In early October 2006, a guard mistakenly gave Taylor
    an extra razor blade. Taylor used the extra blade to fashion a
    knife, or “shank.”
    Then, on October 12, 2006, Taylor was placed in the
    same recreation yard with Bistrian. The guards removed
    Taylor‟s handcuffs before they removed Bistrian‟s, and the
    two paced the yard for almost the entire hour. Taylor testified
    that Bistrian did not make any aggressive move towards him
    during the hour, but, after half an hour, Bistrian asked him
    what he was looking at and, later, told him he was “going
    down,” which Taylor understood to mean that Bistrian was
    “going to come after” him.
    At the end of the hour, Bistrian backed up to the
    wicket to be handcuffed. Taylor, who had not yet been
    handcuffed, followed Bistrian, and, as soon as Bistrian was
    handcuffed, attacked him. Taylor punched Bistrian and
    slashed his face, arms, and legs with the shank. Bistrian fell
    to the ground and kicked at Taylor. Taylor ignored the
    guards‟ repeated commands to stop and continued attacking
    Bistrian for more than two-and-a-half minutes. The guards
    used three cans of pepper spray to try to subdue Taylor but
    did not succeed until they tossed a “flash bang” grenade into
    the yard, stunning him. When the guards entered the yard,
    Taylor told them repeatedly that he “had to get” Bistrian
    before Bistrian got him. Bistrian was treated at the hospital
    4
    for deep cuts to his face, arms, and legs. The entire incident
    was captured on video by the FDC‟s surveillance cameras.
    B. Procedural History
    Taylor was indicted and charged with assault with a
    dangerous weapon, under 
    18 U.S.C. § 113
    (a)(3), and assault
    resulting in serious bodily injury, under 
    18 U.S.C. § 113
    (a)(6), in May 2007. The government ultimately sought
    dismissal of the second count, and the case went to trial on a
    single count of assault with a dangerous weapon on
    November 30, 2010. Taylor did not dispute that he had
    attacked Bistrian, but attempted to show that he was justified
    in doing so. Taylor was convicted on December 3, 2010, and,
    on June 28, 2011, was sentenced to 120 months in prison, to
    be served consecutively to the federal sentence he was
    serving when the assault occurred.
    Before trial, Taylor moved to dismiss the indictment
    for selective prosecution. His theory was that the prosecution
    was racially motivated because he was charged for this
    assault, on a white victim, but had not been charged for an
    earlier assault, also using razor blades, on two black inmates.
    The District Court denied the motion without ordering the
    government to produce discovery or holding a hearing.
    Also before trial, the government filed motions in
    limine for a hearing on, and then to preclude altogether,
    Taylor‟s justification defense. The government argued that
    Taylor‟s evidence, which consisted of testimony from Taylor,
    several fact witnesses, and an expert on prison culture and
    would have described the racial tensions in the prison and
    asserted that Bistrian‟s threats against Taylor justified the
    attack, failed to establish the defense as a matter of law.
    5
    In this Circuit, the elements of justification are:
    First, that [the defendant] was
    under an immediate, unlawful
    threat of death or serious bodily
    injury to himself or to others;
    Second, that [the defendant] had a
    well-grounded [or reasonable]
    fear that the threat would be
    carried out if he did not commit
    the offense;
    Third, that [the defendant‟s]
    criminal action was directly
    caused by the need to avoid the
    threatened harm and that [the
    defendant] had no reasonable,
    lawful opportunity to avoid the
    threatened      harm      without
    committing the offense; that is,
    that [the defendant] had no
    reasonable lawful opportunity
    both to refuse to do the criminal
    act and also to avoid the
    threatened harm; and
    Fourth, that [the defendant] had
    not recklessly placed himself in a
    situation in which he would be
    forced to engage in criminal
    conduct.
    Third Cir. Model Crim. Jury Instr. § 8.04.
    6
    The District Court held a hearing on November 22,
    2010, at which Taylor made an offer of proof. Two days
    later, the District Court denied the government‟s motion
    without prejudice and decided to allow Taylor to testify. The
    Court stated, “I‟m going to allow the defendant to testify to
    whatever the defendant is going to testify to. . . . [I]f the
    defendant testifies to justification, whether or not I allow the
    defendant to call any other witnesses to support that will
    depend entirely on what the defendant has to say.” At the
    same time, the District Court made clear that it was skeptical
    of the merits of Taylor‟s proffer:
    Mr. Cedrone [Taylor‟s attorney],
    as you described [Taylor‟s]
    testimony yesterday, it doesn‟t
    cover all the elements [of a
    justification defense] and the ex
    parte submission you‟ve made
    today . . . also doesn‟t cover all
    the elements. . . . .
    However, I‟m not going to —
    whatever discretion I may have to
    preclude a defendant‟s testimony
    with respect to justification, I‟m
    not going to exercise that
    discretion. I‟m going to allow the
    defendant to testify, tell his story,
    and at the conclusion of his
    testimony we will revisit the issue
    of whether or not you may call
    any witnesses to corroborate that.
    7
    Just to give you an idea of what
    my thinking is, based on your
    proffer, your proffer does not
    offer a defense of justification. It
    covers, perhaps, one element but
    it certainly doesn‟t cover all the
    required elements.
    The government objected to the District Court‟s ruling,
    arguing that, because of the lack of support for his defense,
    Taylor should not be allowed to testify as to justification.
    At trial, Taylor moved for a judgment of acquittal after
    the prosecution rested its case. The District Court denied the
    motion. Taylor took the stand and presented his version of
    the events surrounding the attack. Before he was allowed to
    present additional witnesses, however, the District Court
    asked Taylor for a second offer of proof. Taylor proffered the
    testimony of five fact witnesses and his prison-culture expert.
    None of the proposed witnesses actually saw the assault;
    Taylor proposed that they would testify about the earlier
    incident with the prison psychiatrist, the resulting racial
    tensions, and the fact that Bistrian knew how to escape from
    handcuffs and use them as a weapon (to bolster Taylor‟s
    theory that Bistrian was more dangerous when cuffed than
    when the inmates were pacing together in the yard). After
    Taylor‟s proffer, the District Court precluded him from
    putting on any of the proffered witnesses. It reasoned as
    follows:
    I believe [Taylor] had a
    reasonable lawful opportunity to
    avoid this simply by asking to be
    taken out of the cage. I believe
    8
    that [Taylor] acted recklessly by
    remaining in the cage, where
    according to [Taylor], he was
    being taunted. He was being
    taunted a half hour before the
    attack, and he remained in the
    cage and didn‟t ask to be taken
    out.
    And so assuming for a moment
    that I have to accept the absurd
    notion that a man is more
    dangerous      and    creates      an
    imminent threat when he puts
    himself in handcuffs and that
    [Taylor‟s] attack on him for . . .
    ...
    Two minutes and thirty-seven
    seconds, [Taylor] was attacking
    Mr. Bistrian with a deadly
    weapon through three cans of OC
    spray, I just think you haven‟t
    remotely made out justification. I
    don‟t think there was an
    immediate unlawful threat of
    death or serious bodily injury to
    himself or others.
    I think that taking all the evidence
    in the light most favorable to
    [Taylor], I don‟t think [Taylor]
    thought he was about to attack
    9
    him. I think [Taylor‟s] testimony
    is that he was concerned that he
    might, and he was going to get
    him first.     Taking [Taylor‟s]
    testimony as true, I think your
    client wanted to do a preemptive
    strike, and he thought at some
    point, accepting what he says is
    true, that Mr. Bistrian was going
    to attack him, but certainly not in
    that cage, certainly not in that
    cage.
    And second, that he had a well
    grounded fear or a reasonable
    belief that the threat would be
    carried out if he did not commit
    the offense. Each time he cut Mr.
    Bistrian, that could be construed
    as a separate assault.       And
    certainly by the time Mr. Bistrian
    was on the ground, and [Taylor]
    continued to cut him with the
    knife, he couldn‟t possibly have
    had a well grounded or reasonable
    fear that the threat would be
    carried out if he didn‟t keep
    knifing him.
    But perhaps, perhaps most
    significantly, that Mr. Taylor‟s
    criminal action was directly
    caused by the need to avoid the
    threatened harm, and that Mr.
    10
    Taylor had no reasonable lawful
    opportunity      to   avoid     the
    threatened       harm       without
    committing the offense. I think
    he plainly did, and he didn‟t avail
    himself of that opportunity. He
    didn‟t even try. He never asked
    the guard to be taken out. And I
    don‟t think that — I don‟t think he
    availed himself of that reasonable
    lawful opportunity.
    And so although I would allow
    [Taylor] to call Mr. Bistrian
    because he‟s the victim of this
    case, [Taylor has] elected not to
    call Mr. Bistrian, and the other
    witnesses, I believe down to the
    expert, do not provide . . . ,
    accepting everything they say is
    true, don‟t provide [Taylor] with a
    complete defense of justification,
    and so I have the discretion to
    preclude the presentation of that
    defense.
    The District Court instructed the jury that the government
    bore the burden of proving beyond a reasonable doubt that
    Taylor: (1) struck Bistrian intentionally; (2) used a dangerous
    weapon, i.e., a razor, as charged in the indictment; (3) acted
    with the intent to cause bodily harm; and (4) intentionally
    struck Bistrian within the special maritime and territorial
    jurisdiction of the United States. The District Court declined
    11
    to provide any instruction concerning a just cause or excuse
    for the offense.
    After his conviction, Taylor moved for acquittal and
    for a new trial. The District Court issued a 19-page written
    opinion denying the motions and explaining, among other
    things, its decisions to preclude Taylor from offering
    additional witnesses and not to instruct the jury about
    justification. In response to Taylor‟s argument that the
    absence of just cause or excuse is an element of an 
    18 U.S.C. § 113
    (a)(3) offense, the District Court concluded that the
    absence of just cause or excuse is an affirmative defense to,
    not an element of, a § 113(a)(3) violation.
    Taylor now appeals.1
    II.
    On appeal, Taylor first argues that the District Court
    erred in failing to instruct the jury that the absence of just
    cause or excuse is an element of an 
    18 U.S.C. § 113
    (a)(3)
    offense that the government must establish by proof beyond a
    reasonable doubt. 
    18 U.S.C. § 113
    (a)(3) provides:
    Whoever, within the special
    maritime        and      territorial
    jurisdiction of the United States,
    is guilty of an assault shall be
    punished as follows . . . Assault

    The District Court had jurisdiction over this case under 
    18 U.S.C. § 3231

    with a dangerous weapon, with
    intent to do bodily harm, and
    without just cause or excuse, by a
    fine    under     this  title   or
    imprisonment for not more than
    ten years, or both.
    (emphasis added). The language of this provision is unique in
    the federal assault statute, 
    18 U.S.C. § 113
    : of the seven
    types of assault listed, only this provision, for assault with a
    dangerous weapon, includes a specific reference to “just
    cause or excuse.” Although we cannot be sure why Congress
    included those words in subsection (a)(3), but not in the other
    subsections of the statute, the weight of the authority and
    relevant Supreme Court precedent support the District Court‟s
    conclusion that they refer to an affirmative defense that the
    defendant bears the burden of proving by a preponderance of
    the evidence.
    Few cases have discussed this point in any detail. But,
    as both parties acknowledge, the great majority of cases
    describing the elements of § 113(a)(3) or its predecessor,
    § 113(c), state (without much, or any, supporting analysis)
    that a conviction under that subsection requires proof of only
    three elements: (1) assault; (2) with specific intent to inflict
    bodily harm; and (3) use of a “dangerous weapon.” See, e.g.,
    United States v. Herron, 
    539 F.3d 881
    , 886 (8th Cir. 2008)
    (“The elements of Assault with a Dangerous Weapon require
    that the defendant: 1) assault the victim; 2) intend to do
    bodily harm; and 3) use a dangerous weapon to commit the
    assault.”); United States v. Smith, 
    520 F.3d 1097
    , 1101 (9th
    Cir. 2008) (stating that assault with a dangerous weapon
    under 
    18 U.S.C. § 113
    (a)(3) “has three elements: (1) that the
    defendant intentionally struck or wounded the victim; (2) that
    13
    the defendant acted with the specific intent to do bodily harm;
    and (3) that the defendant used a „dangerous weapon‟”); see
    also United States v. Estrada-Fernandez, 
    150 F.3d 491
    , 494
    (5th Cir. 1998) (per curiam); United States v. Sturgis, 
    48 F.3d 784
    , 786 (4th Cir. 1995); United States v. Johnson, 
    967 F.2d 1431
    , 1433 (10th Cir. 1992), abrogated on other grounds by
    Lewis v. United States, 
    523 U.S. 155
    , 162 (1998). These
    cases do not list the lack of a just cause or excuse as an
    element of the offense.
    Another line of cases acknowledges the statute‟s
    “without just cause or excuse” language and explicitly
    concludes that the government does not need to plead or
    prove the absence of a just cause or excuse to secure a
    conviction under § 113(a)(3). The most recent of these, and
    the one on which the District Court primarily relied, is United
    States v. Guilbert, 
    692 F.2d 1340
     (11th Cir. 1982). In that
    case, after reciting the three elements of assault with a
    dangerous weapon listed above, the court said, “[t]he
    existence of „just cause or excuse‟ for the assault is an
    affirmative defense, and the government does not have the
    burden of pleading or proving its absence.” 
    Id. at 1343
    . The
    opinion cites a string of cases for that proposition, the most
    substantive of which is Hockenberry v. United States, 
    422 F.2d 171
     (9th Cir. 1970). There, the court reasoned:
    It was not necessary [for the
    indictment] to recite that the
    assault was „without just cause or
    excuse.‟ If there was such cause
    or excuse, the defendant could
    show it; the government did not
    have the burden of pleading or
    proving its absence. By a rule of
    14
    long standing, „an indictment or
    other pleading founded on a
    general provision defining the
    elements of an offense, or of a
    right conferred, need not negative
    the matter of an exception made
    by a proviso or other distinct
    clause, whether in the same
    section or elsewhere, and * * * it
    is incumbent on one who relies on
    such an exception to set it up and
    establish it.‟
    
    Id. at 173
     (quoting McKelvey v. United States, 
    260 U.S. 353
    ,
    357 (1922)). Although the reasoning in these cases is not
    extensive, they support the District Court‟s conclusion.2
    2
    Taylor seeks to distinguish these cases by pointing out that
    Hockenberry, which arose out of a challenge to indictment,
    concerned which party bears the burden of pleading
    justification, not which party bears the burden of proving that
    issue. He does not explain the significance of that distinction,
    but he presumably intends to argue that, by including the
    “without just cause or excuse” language in the statute,
    Congress set up a burden-shifting scheme in which the
    defendant bears the burden of raising a justification that the
    government must then disprove beyond a reasonable doubt.
    As we discuss below, the Supreme Court‟s decision in Dixon
    v. United States, 
    548 U.S. 1
     (2006), forecloses any such
    argument. Moreover, even though Taylor is right that
    Hockenberry involved a pleading question, Guilbert did not:
    the issue in that case was whether the evidence was sufficient
    to support a conviction, which necessarily entails the question
    15
    To counter all of this authority, Taylor cites a single
    case: United States v. Bordeaux, 
    570 F.3d 1041
     (8th Cir.
    2009). In Bordeaux, the Eighth Circuit Court of Appeals,
    considering a sufficiency-of-the-evidence challenge to a
    § 113(a)(3) conviction, included “acted without just cause or
    excuse” in a list of elements of the offense, and analyzed
    whether the government “presented sufficient evidence that
    Bordeaux acted without just cause or excuse.” Id. at 1047-48.
    But the court did not consider whether that element should
    more properly be treated as an affirmative defense, and the
    government does not appear to have raised the issue.
    Additionally, as the government points out here, the court‟s
    interpretation of the offense in Bordeaux is inconsistent with
    another of its cases from the previous year, in which it
    omitted the “just cause or excuse” language from a recitation
    of the elements of the offense. See Herron, 
    539 F.3d at 886
    .
    Given these facts, Bordeaux does not present an especially
    compelling counterpoint to the numerous cases suggesting
    that “just cause or excuse” is an affirmative defense.3
    of the burden of proof. Thus, even if Hockenberry is
    distinguishable on the ground Taylor suggests, Guilbert is
    not.
    3
    United States v. Wycoff, 
    545 F.2d 679
     (9th Cir. 1976),
    which Taylor raised in a post-argument submission, is
    similarly unhelpful. There, the court merely affirmed a
    defendant‟s assault-with-a-dangerous-weapon conviction over
    a challenge that the district court failed properly to notify the
    defendant of a change in the jury instructions. 
    Id. at 683
    .
    The district court had decided, at the last minute, to include
    the absence of just cause or excuse as an element of the
    16
    Relevant Supreme Court precedent also supports the
    District Court‟s interpretation. Specifically, in McKelvey v.
    United States, 
    260 U.S. 353
     (1922), the Supreme Court
    rejected an argument that the government erred in failing to
    charge in an indictment that the defendant did not fall within
    an exception contained in the statute.4 It stated:
    offense in its instructions. The government did not dispute,
    and the court did not analyze, the substance of that decision.
    4
    McKelvey involved a charge of unlawfully obstructing free
    passage over unoccupied public lands of the United States.
    The relevant statute stated:
    That no person, by force, threats,
    intimidation, or by any fencing or
    inclosing, or any other unlawful
    means, shall prevent or obstruct,
    or shall combine and confederate
    with others to prevent or obstruct,
    any person from peaceably
    entering upon or establishing a
    settlement or residence on any
    tract of public land subject to
    settlement or entry under the
    public land laws of the United
    States, or shall prevent or obstruct
    free passage or transit over or
    through     the     public    lands:
    Provided, this section shall not be
    held to affect the right or title of

    By repeated decisions it has come
    to be a settled rule in this
    jurisdiction that an indictment or
    other pleading founded on a
    general provision defining the
    elements of an offense, or of a
    right conferred, need not negative
    the matter of an exception made
    by a proviso or other distinct
    clause, whether in the same
    section or elsewhere, and that it is
    incumbent on one who relies on
    such an exception to set it up and
    establish it.

    sufficiency of an indictment, the last sentence of the quoted
    passage suggests that a defendant relying on an exception
    must both raise the exception and “establish it.” In other
    words, where the statute contains such an exception, the
    defendant bears the burden of proving it.5

    We use McKelvey to illustrate our point here because it is
    often cited as the source of this rule. See, e.g., Dixon, 
    548 U.S. at 13-14
    . In fact, however, numerous Supreme Court
    decisions before McKelvey, dating back at least to 1841, held
    18
    Of course, that is not the end of the analysis: applying
    the McKelvey rule in this case naturally begs the question
    whether the “just cause or excuse” language in § 113(a)(3)
    qualifies as an “exception made by a proviso or other distinct
    clause.” Whether a particular statutory phrase constitutes a
    defense or an element of the offense under McKelvey turns on
    whether “the statutory definition is such that the crime may
    not be properly described without reference to the exception.”
    United States v. Prentiss, 
    206 F.3d 960
    , 973 (10th Cir. 2000)
    (citing United States v. Cook, 
    84 U.S. 168
    , 173-74 (1872)),
    aff’d in relevant part, 
    256 F.3d 971
    , 980 (10th Cir. 2001) (en
    banc). If so, the exception is an element of the crime. If not,
    the exception is a defense. We conclude that, under the plain
    language of McKelvey as supplemented by this test, the “just
    cause or excuse” is a defense to, rather than an element of,
    § 113(a)(3).
    As McKelvey requires, the “without just cause or
    excuse” language in § 113(a)(3) appears in a “distinct
    clause,” set off by commas from the rest of the statute. This
    alone is not dispositive, however, since the phrase “with
    that the party who wishes to rely on an exception to an Act of
    Congress must raise it and establish it. See, e.g., Schlemmer
    v. Buffalo, Rochester & Pittsburgh Ry., 
    205 U.S. 1
    , 10 (1907)
    (holding that a defendant who “wishe[s] to rely upon [a]
    proviso” bears “the burden . . . to bring itself within an
    exception”) (internal quotation marks omitted)) (Holmes, J.);
    United States v. Dickson, 
    40 U.S. 141
    , 165 (1841) (“In short,
    a proviso carves special exceptions only out of the enacting
    clause; and those who set up any such exception, must
    establish it as being within the words as well as within the
    reasons thereof.”).
    19
    intent to do bodily harm,” which does set forth an element,
    also appears in a distinct clause. More importantly, the
    former clause falls outside of the “definition” test set forth
    above because the offense may properly be described as an
    “[a]ssault with a dangerous weapon, with intent to do bodily
    harm,” without referencing the “just cause or excuse”
    language.6 Indeed, as discussed above, most cases that have
    identified the elements of the offense have done precisely
    that. Thus, we have no problem concluding that the “without
    just cause or excuse” language in § 113(a)(3) is an “exception
    made by a . . . distinct clause,” such that, under McKelvey, “it
    is incumbent on” the defendant, “who relies on” the
    exception, “to set it up and establish it.” 
    260 U.S. at 357
    .
    Another, more recent Supreme Court case, Dixon v.
    United States, 
    548 U.S. 1
     (2006), reinforces our conclusion
    that Taylor bore the burden of establishing the existence of a
    just cause or excuse in this case. In Dixon, the defendant,
    who was indicted and tried on federal firearms charges,
    asserted a duress defense. She argued that as the defendant,
    she bore the burden of production on the defense, but that the
    burden then shifted to the government to disprove it beyond a
    reasonable doubt.
    The Supreme Court disagreed. It first concluded that
    placing the burden of proving duress on the defendant did not
    6
    Taylor effectively concedes this point in his brief, when he
    states that the statute “requires the government to prove the
    absence of „just cause or excuse‟ when applicable under the
    facts of a given case.” Appellant‟s Br. 31 (emphasis added).
    If, as Taylor suggests, the “just cause or excuse” language
    does not apply in every case, then, plainly, the absence of a
    just cause or excuse is not an essential element of the offense.
    20
    violate the Due Process Clause of the Constitution because
    proof of duress could “in no way disprove[] an element” of
    the firearm-possession charge, including the requisite
    “knowing” mens rea. 
    Id. at 7
    ; see also United States v. Dodd,
    
    225 F.3d 340
    , 344 (3d Cir. 2000) (“Although the Due Process
    Clause requires the government to prove all elements of the
    charged offense beyond a reasonable doubt, and therefore
    requires the government to disprove beyond a reasonable
    doubt any defenses that negate an element of the charged
    offense, there is no constitutional bar to the defendant‟s
    bearing the burden of persuasion on defenses that do not
    negate an element of the offense.”).
    The Dixon Court also held that placing the burden of
    proving duress on the defendant in that case comported with
    federal common law. It noted that, “at common law, the
    burden of proving affirmative defenses—indeed, all . . .
    circumstances of justification, excuse or alleviation—rested
    on the defendant.” Dixon, 
    548 U.S. at 8
     (internal quotation
    marks and citations omitted). This rule, the Court went on to
    explain, “accords with the general evidentiary rule that the
    burdens of producing evidence and of persuasion with regard
    to any given issue are both generally allocated to the same
    party” and “the doctrine that where the facts with regard to an
    issue lie peculiarly in the knowledge of a party, that party has
    the burden of proving the issue.” 
    Id.
     (internal quotation
    marks and citations omitted). The Court then reasoned that,
    even though the firearm offense statute “does not mention the
    defense of duress,” it could “safely assume that the 1968
    Congress [that enacted the firearm statute] was familiar with
    both the long-established common-law rule and the rule
    applied in McKelvey” and that Congress “would have
    expected federal courts to apply a similar approach to any
    21
    affirmative defense that might be asserted as a justification or
    excuse for violating the new law.” 
    Id. at 13-14
     (footnote
    omitted). In other words, the Court “presume[d] that
    Congress intended the petitioner to bear the burden of proving
    the defense of duress by a preponderance of the evidence.”
    
    Id. at 17
    .
    The same logic applies in this case. The existence of
    just cause or excuse does not disprove the elements of assault
    under § 113(a)(3), namely, physical attack, intent to do bodily
    harm, and use of a dangerous weapon. Accordingly, under
    the rule of Dixon and Dodd, placing the burden of proving the
    absence of just cause or excuse on the defendant does not run
    afoul of the Due Process Clause.
    And, as Dixon makes clear, placing the burden of
    proving justification on Taylor in this case also is consistent
    with common law and basic principles of statutory
    interpretation. The same common-law rule that places the
    burden of proving duress on the defendant also applies to
    issues involving justification or excuse. Id. at 8. That rule
    makes sense here for the same reasons the Court noted in
    Dixon: it allocates the burdens of production and persuasion
    to the same party, and it places those burdens on the party
    with peculiar knowledge of the relevant facts. In this case,
    Taylor‟s justification defense depended on his testimony that
    he feared that Bistrian would attack him first and that he
    feared Bistrian would slip out of his handcuffs and use them
    as a weapon. Particularly given its inability to compel Taylor
    to testify, the government would have had a difficult time
    obtaining that information on its own.
    Moreover, the inference about congressional intent the
    Court relied on in Dixon — that, absent some indication to
    22
    the contrary, Congress intended that the “long-established
    common-law rule” that the defendant bears the burden of
    proving justification or excuse and “the rule applied in
    McKelvey” would guide federal courts‟ analyses — applies
    with even greater force in this case.7 If we are to presume, as
    the Court did in Dixon, that Congress legislates with those
    rules in mind, then surely more than a simple reference to a
    particular defense, as in § 113(a)(3), is needed to evince
    Congress‟s intent to convert a traditional common-law
    defense into an element of the government‟s affirmative case.
    Indeed, given that the Dixon Court considered the absence of
    any reference to a duress defense in the firearm statute to be a
    weakness, see, e.g., 
    548 U.S. at 13-14
     (“Even though the Safe
    Streets Act does not mention the defense of duress, we can
    safely assume that the 1968 Congress was familiar with both
    the long-established common-law rule and the rule applied in
    McKelvey and that it would have expected federal courts to
    apply a similar approach to any affirmative defense that might
    be asserted as a justification or excuse for violating the new
    law.” (emphasis added) (footnote omitted)), the same
    inferences must apply even more forcefully in a case like this
    one, in which the statute specifically mentions the defense.
    Accordingly, we interpret § 113(a)(3)‟s reference to a
    justification or excuse as a reference to common-law
    7
    We are aware that McKelvey was decided in 1922, whereas
    the relevant statutory language in this case was enacted
    earlier, in 1909. But, as noted above, the principle for which
    McKelvey stands was established and applied in numerous
    pre-1909 Supreme Court decisions. Thus, the substance of
    Dixon‟s presumption retains its force in this case.
    23
    justification and excuse defenses, which the defendant bears
    the burden of proving by a preponderance of the evidence.8
    We do not lightly dismiss Taylor‟s textual argument,
    that reading the statute in this way renders the words “without
    just cause or excuse” superfluous because courts have
    allowed defendants to raise common-law justification
    defenses to the other subsections of § 113 that do not contain
    8
    For similar reasons, Dixon also forecloses Taylor‟s
    alternative argument that the reference to just cause or excuse
    in § 113(a)(3) implies a complicated burden-shifting
    paradigm, in which the burden shifts to the government to
    disprove justification beyond a reasonable doubt after the
    defendant raises the issue and adduces some evidence to
    support it. See Appellant‟s Reply Br. 5-6 (citing United
    States v. Lawrence, 
    349 F.3d 109
    , 122 (3d Cir. 2003)). For
    one thing, nothing in the text of the statute suggests such an
    approach. It would run counter to Dixon‟s presumption that
    Congress legislates with common-law principles in mind to
    conclude that Congress intended to set up a burden-shifting
    scheme when all it did was use the words “without just cause
    or excuse.” More directly, this is precisely the argument that
    the Supreme Court rejected in Dixon. Dixon conceded that
    she bore the burden of production on her duress defense, 
    548 U.S. at 4
    , but argued that “modern common law” requires the
    government to disprove affirmative defenses beyond a
    reasonable doubt in criminal cases, see 
    id. at 8
    . The Supreme
    Court rejected that argument and applied “[t]he long-
    established common-law rule . . . that the burden of proving
    duress rests on the defendant” instead. 
    Id. at 15
    . Taylor has
    offered us no reason to conclude, contrary to Dixon, that the
    ordinary common-law rule does not govern this case as well.
    24
    that phrase. Indeed, we confess that, given the complete
    absence of legislative history and the fact that the language
    was first added to the statute in 1909, we cannot be entirely
    sure what Congress had in mind. But two additional points
    bolster our conclusion that “without just cause or excuse” is
    not an element of a § 113(a)(3) offense. First, although
    mindful of the general principle that we should avoid
    interpretations that effectively read words out of a statute, see,
    e.g., Rosenberg v. XM Ventures, 
    274 F.3d 137
    , 141 (3d Cir.
    2001), we believe that the specific, on-point Supreme Court
    cases in this area, McKelvey and Dixon, take precedence over
    that broad, generally applicable canon of statutory
    interpretation here.
    Second, we question the foundations of Taylor‟s
    argument. Taylor presumes that defendants charged with
    assaults under subsections of § 113 other than § 113(a)(3)
    may pursue common-law defenses, and, indeed, the
    government admits that its practice has been not to object to
    self-defense or other justification instructions in cases
    prosecuted under other subsections of § 113. But the
    government‟s practice is not conclusive evidence of
    congressional intent. Because “federal crimes are defined by
    statute rather than by common law,” United States v. Oakland
    Cannabis Buyers’ Coop., 
    532 U.S. 483
    , 490 (2001), the
    availability of common-law defenses to federal crimes is not a
    foregone conclusion, cf. 
    id. at 491
     (reserving the question
    whether common-law necessity “can ever be a defense when
    the federal statute does not expressly provide for it”); see also
    Dixon, 
    548 U.S. at
    13 & n.7 (assuming, without deciding, that
    common-law duress defense is available to federal statutory
    firearm crime). Perhaps, by including the “without just cause
    or excuse” language in the predecessor versions of
    25
    § 113(a)(3), but not in the other subsections of § 113,
    Congress intended to make common-law justification and
    excuse defenses available for assaults with a dangerous
    weapon, but not for the other assault offenses set forth in
    § 113. We need not reach any definitive conclusion on this
    issue, however, because we are satisfied that the other reasons
    set forth above adequately support our conclusion as to the
    meaning of those words in § 113(a)(3).
    In light of McKelvey, Dixon, and for the reasons
    discussed above, we agree with the District Court that in this
    case the burden of proving a “just cause or excuse” for the
    assault rested with Taylor, the defendant.
    III.
    Taylor raises three additional issues, none of which
    warrants reversal. First, Taylor challenges the District
    Court‟s exclusion of certain additional witnesses related to his
    justification defense and its refusal to instruct the jury on
    justification. But, as the District Court correctly found, the
    evidence plainly does not support such a defense. Second,
    Taylor argues that the District Court infringed his Fifth
    Amendment right against self-incrimination by “forcing” him
    to testify as a condition precedent to admitting the remaining
    evidence of his justification defense. In fact, though, the
    District Court did not force Taylor to testify at all, and it
    clearly informed him from the outset that the proffered
    evidence was insufficient to establish justification as a matter
    of law. Third, and finally, Taylor appeals the District Court‟s
    denial of his motion to dismiss the indictment for selective
    prosecution. Taylor‟s theory here — that he was prosecuted
    for an assault on a white inmate, but not for an earlier assault
    on two black inmates — does not suggest, let alone provide
    26
    the required “clear evidence” of, discriminatory intent or
    effect.
    A.
    The District Court did not err in precluding Taylor
    from offering additional witnesses to support his justification
    defense or in refusing to include the defense in its jury
    charge. The tests for precluding a defendant from offering a
    defense and for denying an instruction on a particular defense
    are the same: whether the evidence presented (or proffered)
    is legally sufficient to support the defense. See United States
    v. Mike, 
    655 F.3d 167
    , 175 (3d Cir. 2011) (defendant whose
    evidence does not support a particular affirmative defense is
    not “entitled” to a jury instruction on that defense); United
    States v. Miller, 
    59 F.3d 417
    , 421-22 (3d Cir. 1995) (district
    court did not err in precluding defendant from offering
    evidence of duress where proffered evidence was insufficient
    to establish duress as a matter of law); cf. Mathews v. United
    States, 
    485 U.S. 58
    , 63 (1988) (“As a general proposition a
    defendant is entitled to an instruction as to any recognized
    defense for which there exists evidence sufficient for a
    reasonable jury to find in his favor.” (emphasis added)).
    The District Court properly analyzed Taylor‟s proffer
    under the Model Jury Instructions,9 and concluded that his
    9
    Taylor‟s argument on appeal that the District Court applied
    the wrong test to evaluate his justification defense is
    meritless. The model instruction applies broadly across all
    types of cases. Moreover, although Taylor argues that the
    District Court should have evaluated his defense according to
    “general justification principles,” he does not articulate what
    27
    proposed defense did not satisfy any of the required elements,
    as follows. First, Taylor was not facing an immediate threat
    of attack because Bistrian was handcuffed. Second, Taylor
    did not have a reasonable fear that the threat would be carried
    out if he did not attack Bistrian. Taylor‟s assertion that
    Bistrian was more dangerous in handcuffs, since he knew
    how to escape them and use them as a weapon, was belied by
    the fact that Taylor did not feel the need to attack Bistrian
    when he was handcuffed at the beginning of the recreation
    hour. Third, Taylor‟s attack was not directly caused by a
    need to avoid harm because it was not made in response to
    any immediate threat by Bistrian. Despite Bistrian‟s alleged
    verbal threat to Taylor during the recreation time, Bistrian
    and Taylor had been pacing together in the same cage without
    any physical contact for almost an hour before Taylor
    attacked. Moreover, Taylor did not take any steps to avoid
    any perceived threat, e.g., he did not report the threats to
    prison staff or ask to be removed from the yard at any time.10
    Fourth, and finally, by choosing to remain in the yard with
    Bistrian, rather than asking the authorities to take him back to
    his cell (which the prison guards testified they would have
    those principles are or how they differ from the model-
    instruction standard the District Court applied.
    10
    Also, as the District Court pointed out in its oral decision,
    the attack continued for two minutes and thirty-seven
    seconds, despite the guards‟ use of three cans of pepper spray,
    and only ended when the guards used a “flash bang” grenade
    to stun Taylor. All of those facts are inconsistent with
    limited, defensive action that is necessary to avoid imminent
    harm.
    28
    done), Taylor recklessly placed himself in the situation that
    gave rise to the assault.
    The District Court‟s conclusions are manifestly
    correct. Moreover, as the District Court also noted, none of
    the testimony Taylor proffered would have remedied the
    defects the District Court identified. On this record, it is
    difficult to imagine any reasonable person reaching a contrary
    result.
    B.
    Taylor argues that the District Court violated his Fifth
    Amendment rights by requiring him to take the stand as a
    condition precedent to the presentation of his justification
    defense. To support his argument, Taylor relies primarily on
    Brooks v. Tennessee, 
    406 U.S. 605
     (1972), in which the
    Supreme Court held that a Tennessee statute that required
    defendants who intended to testify to take the stand as the
    first defense witness violated the Fifth Amendment. Noting
    that a defendant “cannot be absolutely certain that his
    witnesses will testify as expected or that they will be effective
    on the stand,” the Court held that the Tennessee statute “cast[]
    a heavy burden on a defendant‟s otherwise unconditional
    right not to take the stand” by forcing him to testify before the
    precise contours of the other witnesses‟ testimony were
    known. 
    Id. at 609-11
    . The same thing happened in this case,
    Taylor argues, because the District Court suspended its ruling
    on the merits of his justification defense until after he
    testified, thereby denying Taylor the choice to remain silent
    depending on the testimony of the other witnesses.
    That argument fails on the facts. The District Court
    did not force Taylor to testify. Instead, it denied the
    29
    government‟s request to preclude Taylor from testifying.11
    And, unlike in Brooks, the District Court here was not
    enforcing a blanket rule about defendant‟s testimony; it made
    a careful, case-specific and well founded decision after
    considering the defendant‟s proffer. Furthermore, the District
    Court made clear from the outset, before Taylor testified, that
    it did not believe that Taylor‟s testimony, standing alone or as
    corroborated by the proposed additional witnesses, would
    establish all of the necessary elements of a justification
    defense, allowing Taylor to make an informed decision as to
    whether he should testify. Thus, this case simply does not
    raise the same type of concerns as Brooks.
    Moreover, as the District Court pointed out (and
    Taylor‟s counsel acknowledged), the testimony of the other
    witnesses, none of whom observed the actual assault, was
    offered only to “corroborate or support” Taylor‟s version of
    events. Absent Taylor‟s testimony, then, none of the other
    witnesses‟ testimony would even have been relevant to the
    case.12 Thus, the alternative to the District Court‟s ruling in
    11
    Under the circumstances of this case, we need not, and do
    not, evaluate the District Court‟s statement that it could have
    precluded Taylor from testifying altogether.
    12
    In that respect, this case is like United States v. Singh, 
    811 F.2d 758
     (2d Cir. 1987), in which the Second Circuit Court of
    Appeals rejected a defendant‟s argument based on Brooks.
    There, the district court had precluded the defendant from
    pursuing certain lines of cross examination based on hearsay
    until the defendant offered a first-hand account of the
    underlying events. The Second Circuit concluded that “the
    [district] court did not compel appellant to testify at all”;
    30
    this case was not that Taylor would have remained silent until
    all of the other witnesses testified, as the Court envisioned in
    Brooks; it was that all of the testimony, including Taylor‟s,
    would have been excluded.13 We do not find any Fifth
    Amendment violation in this case.
    C.
    Finally, Taylor appeals the District Court‟s decisions
    denying his motion to dismiss the indictment for selective
    prosecution and denying him discovery on that motion. His
    theory is that he was improperly selected for prosecution
    because his victim in this case was white. To support that
    instead, “[i]t merely refused to accept the proffered testimony
    of other witnesses until a proper foundation was laid.” 
    Id. at 762
    . The same is true here: Taylor‟s testimony provided the
    necessary foundation for the testimony of the other proposed
    witnesses. See generally Geders v. United States, 
    425 U.S. 80
    , 86 (1976) (trial judge in a criminal case “may determine
    generally the order in which parties will adduce proof”; “may
    refuse to allow cumulative, repetitive, or irrelevant
    testimony”; and must “exert substantial control over the
    proceedings”).
    13
    We note, further, that Taylor did not suffer any prejudice
    from the District Court‟s ruling. This is not a case in which
    the defendant would have been acquitted absent his
    purportedly forced testimony. Because the entire assault was
    captured on prison videotape, there was no question as to
    what happened or who was responsible for the assault; the
    only question was whether Taylor‟s actions were justified.
    And, as discussed above, the evidence Taylor proffered on
    that issue was legally insufficient to support his defense.
    31
    claim, he pointed out that he was not prosecuted for an earlier
    assault on two black victims.
    When analyzing selective prosecution claims, we
    review district courts‟ findings of facts for clear error and the
    application of legal precepts de novo. United States v.
    Schoolcraft, 
    879 F.2d 64
    , 67 (3d Cir. 1989). The district
    court‟s denial of discovery on such a motion is reviewable for
    abuse of discretion. United States v. Hedaithy, 
    392 F.3d 580
    ,
    605 (3d Cir. 2004).
    To establish selective prosecution, the defendant must
    “provide evidence that persons similarly situated have not
    been prosecuted” and that “the decision to prosecute was
    made on the basis of an unjustifiable standard, such as race,
    religion, or some other arbitrary factor.” Schoolcraft, 
    879 F.2d at 68
    . The defendant bears the burden of proof, 
    id.,
     and
    must establish each of these elements with “clear evidence”
    sufficient to overcome the presumption of regularity that
    attaches to decisions to prosecute, United States v. Armstrong,
    
    517 U.S. 456
    , 464 (1996). “The required threshold to obtain
    discovery” on such a motion is “some evidence tending to
    show the existence of the essential elements of the defense,
    discriminatory effect and discriminatory intent.” Hedaithy,
    
    392 F.3d at 607
     (internal quotation marks omitted).
    Given these high standards, it is clear that the District
    Court in this case did not abuse its discretion by denying
    Taylor discovery or err in denying his motion to dismiss.
    That Taylor was prosecuted for one assault, but not for
    another, does not, without more, provide “clear evidence” of
    a discriminatory effect or discriminatory intent. Taylor has
    not offered any other examples of defendants who assaulted
    both white and black inmates, but were only prosecuted for
    32
    assaulting the white inmates. And Taylor-after-the-second-
    assault is not “similarly situated” to Taylor-after-the-first-
    assault for the obvious reason that the incident that gave rise
    to the charges in this case occurred against the backdrop of
    Taylor‟s history of disciplinary problems, including the
    previous assault on the black inmates. Accordingly, Taylor
    did not present sufficient evidence to satisfy the threshold for
    obtaining discovery on his selective prosecution claim, let
    alone dismissal of the indictment on those grounds, and this
    argument does not provide any basis on which we could or
    should reverse the judgment of the District Court.
    IV.
    For the foregoing reasons, we will affirm the judgment
    of the District Court.
