    Circuit Judges.

    THOMPSON,    Circuit    Judge.   After    evading      authorities   for
    fifteen-plus years, fugitive James "Whitey" Bulger, the head of an
    organized crime syndicate in Boston from the 1970's to the 1990's,
    was captured.       Bulger, who had been indicted in connection with a
    racketeering conspiracy while on the run, was brought to trial.
    The jury found him guilty of the vast majority of charged crimes
    and he was sentenced to life in prison.                   Bulger appeals the
    conviction, claiming that he was deprived of his right to a fair
    trial when both the government and trial court got a few things
    wrong prior to and during trial.             Having closely considered the
    array of claimed errors, we affirm.
    I. BACKGROUND
    The factual underpinning of this case is considerable.               The
    events span decades and the cast of characters is large but this
    appeal is circumscribed in scope making only certain details
    pertinent.     We chart the relevant origin and travel of the case,
    saving the facts related to the maintained errors for later.1
    A. The Indictment
    In 2001, Bulger, who was on the run and had been for some
    time,    was   charged   with    thirty-two      counts   of    a   racketeering
    1 Bulger does not lodge a sufficiency of the evidence challenge.
    Rather his grievance relates to various evidentiary issues and,
    so, we present a more neutral summary of the facts up front,
    adjusting our approach as needed later. United States v. Flores-
    Rivera, 
    787 F.3d 1
    , 9 (1st Cir. 2015).

    indictment along with Stephen Flemmi.2           It alleged that Bulger and
    Flemmi were members of a criminal organization known as Winter
    Hill (or some variation on this moniker) and part of a racketeering
    conspiracy that extended from around 1972 to 2000 in South Boston.
    Bulger,    it   said,    participated     in   multiple   racketeering   acts,
    including nineteen murders, extortion, narcotics distribution, and
    money laundering.3         There were also an assortment of weapons
    charges,    e.g.,       possession   of    firearms   and    machineguns    in
    furtherance     of   a    violent    crime,    possession    of   unregistered
    machineguns, and transfer and possession of machineguns.
    B. Arrest and Trial
    Law enforcement finally caught up with Bulger in June of 2011,
    finding him living under an assumed identity in California.                He
    was arrested and from there brought back to Massachusetts to stand
    trial.
    There was a good deal of pretrial skirmishing among the
    parties and rulings from the court, the particulars of which we
    will detail later.         The same goes for the midtrial clashes and
    edicts.    We will chronicle those later too.             For now we focus on
    2 Flemmi's brother, Michael Flemmi, was also charged. Michael was
    said to have provided unlawful assistance to his brother and other
    gang members at various points, e.g., obstruction of justice and
    weapons possession.
    3  The   racketeering  count   alleged  thirty-three   underlying
    racketeering acts. Some acts were charged as a conspiracy, some
    acts as stand-alone substantive charges, and some as both.

    the substantive case that was presented to the jury over the course
    of the three-month trial.
    C. The Government's Case
    The government called scores of witnesses: participants in
    Bulger's operations, law enforcement officials, and forensics
    experts.    Some of the testimony came from Bulger's closest Winter
    Hill associates -- Flemmi, John Martorano, and Kevin Weeks -- who
    had   all   cut   plea    deals    with    the   government,    swapping   their
    cooperation for various benefits.            The jury heard the following.
    The government placed the start of the conspiracy at a 1972
    meeting where Bulger's gang and another gang decided to go in
    together    on    some    kind    of    "gambling   business"   that   targeted
    individuals not affiliated with the mafia (also known as New
    England La Cosa Nostra).               A string of murders followed in the
    ensuing years, which testimony linked Bulger to, along with other
    criminal activities.
    Then around 1975, according to government witnesses, Bulger
    began acting as an informant to John Connolly, a Federal Bureau of
    Investigation ("FBI") agent.              At some point, their relationship
    turned corrupt.          Martorano and Flemmi (the latter, by his own
    admission, had been an FBI informant dating back to the 1960's),
    testified that Connolly began alerting Bulger to investigations
    being made into Winter Hill's illegal conduct and Bulger, in turn,
    - 4 -
    lavished     Connolly   with   gifts   and    cash,    with   approximately
    $230,000-plus going to Connolly over the years.4
    For Bulger and his cohorts, the 1980's brought more murders
    and the continued use of violence to extort large sums of money
    from individuals. There were also a couple newer ventures: shaking
    down drug dealers for a share of their profits and purchasing real
    estate utilizing illegally obtained money.
    The enterprise began to crumble in the summer of 1990 when
    law   enforcement   arrested   some    individuals     involved   in   Winter
    Hill's drug venture.       Fast forward a few years to 1994 when,
    according to cohort Weeks, he was approached by Connolly who
    informed   him   that    indictments    for   Bulger    and   Flemmi   "were
    imminent."    Weeks passed on the message to both.        Bulger took heed
    and fled, and after some short-term stops in New York and Chicago,
    ended up in Santa Monica, California, where he remained until his
    June 2011 arrest.
    For his part, Flemmi stuck around and indeed was arrested in
    January of 1995.        He tried to avoid being prosecuted, arguing
    during pretrial proceedings that he had been a secret FBI informant
    and so was immune from prosecution.            With the courts holding
    otherwise, See United States v. Salemme, 
    91 F. Supp. 2d 141
     (D.
    4 Connolly was not the only compromised public official. According
    to the testimony, Winter Hill had similar quid pro quo arrangements
    with other corrupt law enforcement officers.
    - 5 -
    Mass 1999); United States v. Flemmi, 
    225 F.3d 78
     (1st Cir. 2000),
    Flemmi agreed to cooperate with the government.             In 2003, Flemmi
    pled guilty to twelve murders, extortion, narcotics crimes, money
    laundering, obstruction of justice, perjury, and firearms charges.
    By the time of Bulger's 2013 trial, Flemmi was serving a federal
    life sentence, as well as life sentences in Oklahoma and Florida.
    Because of his agreement to assist the government, Flemmi avoided
    the death penalty in those two states and got placed in a Federal
    Bureau    of    Prisons   segregated     unit   for   government     witnesses
    (according to Flemmi, the living conditions are better there than
    in general population).
    Like Flemmi, Martorano was arrested in January of 1995.
    Martorano, who had been a fugitive since 1979, was picked up down
    in Florida.     He pled guilty to various federal charges, including
    ten federal murders, as well as two state murders.                 In exchange
    for   cooperating    against    Bulger    (if   apprehended)    and    Flemmi,
    Martorano got just a fourteen-year sentence, to be served in a
    special   facility    for   government      witnesses,   with   five    years'
    supervised release.       On top of that, Martorano was allowed to use
    property seized by the government to settle a judgment his ex-wife
    had secured against him.        He was released from prison in 2007.
    Weeks was arrested in November of 1999 by the Drug Enforcement
    Agency    and   Massachusetts    State    Police.      He   pled    guilty   to
    racketeering crimes plus five murders, and received immunity for
    - 6 -
    some state crimes, in exchange for his full cooperation.                     The plea
    terms required him to testify in any case that was pending or
    brought within three years of his plea agreement.                    Bulger's trial
    marked the fifth or sixth trial that Weeks took the stand for.
    As for Connolly, Bulger's FBI handler, he was indicted in
    1995 (along with Bulger, Flemmi, and Martorano) for the murder of
    a businessman that Winter Hill had dealings with.                      Connolly was
    convicted by a jury some years later.               At the time of Bulger's
    trial, Connolly was serving his sentence down in Florida, after
    having also been convicted of some federal charges in Massachusetts
    stemming from his relationship with Winter Hill.
    D. The Defense
    Bulger's    defense      strategy    was     laid    out    during       opening
    statements.     It     was   not   a   wholesale    denial      of    any    criminal
    wrongdoing.      Instead      counsel     tried     to    poke       holes   in    the
    government's    case    by   casting     doubt     on    the    veracity      of   the
    cooperating witnesses' testimony, namely Flemmi, Martorano and
    Weeks.   The defense harped on their background and character, as
    well as "the unbelievable incentives the prosecution has given
    these three men so that they will testify in the manner that the
    government wants."       It also sought to undercut the prosecution's
    case by emphasizing the rampant corruption among federal law
    enforcement at the time.           And counsel vigorously disputed the
    notion that Bulger had been an informant, instead claiming that he
    - 7 -
    paid Connolly and other law enforcement members large sums of money
    in   exchange    for     information    meant    to    ensure     the   continued
    productivity of his criminal enterprise.
    These     themes     continued     through      the    defense's     cross-
    examination of government witnesses and direct examination of its
    own witnesses, namely law enforcement agents.               Bulger did not take
    the stand.
    E. The Verdict and Sentence
    Eventually both sides wrapped up and after deliberating for
    four days, the jury found Bulger guilty on all counts, save one
    extortion count.         With respect to the racketeering count in
    particular, the jury found the government had proven some, though
    not all, of the thirty-three racketeering acts alleged. The proven
    ones included the murder of (and sometimes also the conspiracy to
    murder) eleven individuals, multiple instances of extortion and
    money   laundering,       and   one     act     of    narcotics     distribution
    conspiracy.     Following a hearing, the trial judge sentenced Bulger
    to life in prison, with an additional life and five-year sentence
    to be served consecutively.
    F. This Appeal
    Bulger timely appealed. As alluded to above, he assigns error
    to various court rulings and condemns certain actions of the
    government.      Bulger would have us find that standing alone, or
    - 8 -
    cumulatively,    the     alleged    miscues    warrant      reversal    of   his
    conviction and a new trial.
    II. IMMUNITY
    Bulger's first claimed error relates to the court's pretrial
    decision that barred Bulger from asserting at trial that he was
    immune from prosecution, immunity, Bulger says, he was granted
    long ago by a government attorney, one Jeremiah O'Sullivan.                  We
    start with what happened below.
    A. Background
    Prior to trial, the defense filed a discovery motion seeking
    all correspondence between various law enforcement agencies, e.g.,
    FBI,   United   States    Attorney's   Office,    Department      of    Justice
    ("DOJ"), and individual Winter Hill members, such as, Bulger,
    Flemmi,   and   Martorano.     As    grounds    for   the    request,    Bulger
    indicated that he "intend[ed] to show at trial that [he] had
    immunity for the indicted conduct."         Specifically, he claimed that
    now-deceased former federal prosecutor, Jeremiah O'Sullivan, who
    previously headed the DOJ's New England Organized Crime Strike
    Force, promised Bulger that he would not be prosecuted for his
    crimes.
    The government opposed the request, calling the immunity
    claim "frivolous and absurd," and asked the court to decide
    pretrial that Bulger did not have an enforceable immunity agreement
    with the government.         In additional briefing, the government
    - 9 -
    produced an affidavit from Associate Deputy Attorney General David
    Margolis, who, in his capacity as Chief of the DOJ's Organized
    Crime and Racketeering Section during O'Sullivan's tenure, had
    been responsible for supervising O'Sullivan.                         Boiled down, the
    affidavit said that O'Sullivan would not have had the authority to
    confer    immunity      on    Bulger.          Margolis   explained      that   certain
    approval      practices       adhered     to    non-prosecution        agreements    and
    grants of use immunity, and that O'Sullivan had never discussed
    with him (or his deputies) the prospect of any agreement with
    Bulger, nor sought the required authorization to enter into such
    an agreement.         Margolis stated that "if O'Sullivan did, in fact,
    enter into any immunity or non-prosecution agreement with James
    Bulger without obtaining the proper approvals, O'Sullivan would
    have acted beyond the scope of his authority."                       The same went for
    any purported agreement with O'Sullivan that contemplated immunity
    for future violent criminal conduct, a concept Margolis deemed
    "foreign."
    The     court    (a     different      judge     from    the   trial   judge   was
    presiding over the case back then), after conducting a hearing,
    ruled    on   the     issue    in    March     2013.      It   found    that    pretrial
    resolution of the immunity claim was warranted, and that Bulger's
    claim of immunity for any crimes prospective to the grant (i.e.,
    crimes that Bulger committed after O'Sullivan's purported promise)
    was   without       authority       and   unenforceable.         The    court   ordered
    - 10 -
    supplemental briefing on the issue of historical immunity (i.e.,
    crimes committed before the alleged immunity promise) so that
    Bulger could properly respond to the recently produced Margolis
    affidavit.    The parties were also given the opportunity to request
    an evidentiary hearing.
    When the judge who made the initial ruling ended up recusing
    from the case, and the ultimate trial judge took over, Bulger moved
    to vacate the March 2013 order.5   After hearing argument, the court
    issued its decision.      Though it found no reason to vacate the
    original order, it nonetheless decided to revisit the issues the
    order had dealt with.
    First, the court found that whether or not a valid immunity
    agreement existed was indeed an issue for a judge's consideration,
    as opposed to a jury's, for a few reasons.    For one, it held that
    immunity was a bar to prosecution that needed to be decided by the
    court beforehand, as opposed to a defense that might go to the
    jury.    The court also concluded that the question of immunity was
    entirely severable from the issue of whether Bulger was guilty or
    5 The original judge was Judge Richard Stearns, whom Bulger
    petitioned to have recused given the judge's background in federal
    prosecution during the time period at issue in this case. This
    court granted that petition. In re Bulger, 
    710 F.3d 42
     (1st Cir.
    2013). To be clear, this court did not find (and there was no
    claim) that Judge Stearns was actually biased.     
    Id. at 46, 49
    .
    Rather, this court concluded that "a reasonable person might
    question the judge's ability to preserve impartiality." 
    Id. at 49
    . The ultimate trial judge, Judge Denise Casper, was assigned
    to take over.
    - 11 -
    innocent of the charged crimes.        Plus, deciding the issue pretrial
    would either narrow the focus at trial, or, in the event things
    went the other way, prevent an unnecessary trial.
    As for the merits of Bulger's immunity claim, the court found
    that Bulger had offered only a bare assertion (through defense
    counsel's   representations)    that     O'Sullivan    gave    him   immunity
    sometime before 1984, which extended until 1989 when O'Sullivan
    left the United States Attorney's Office.              Bulger provided no
    evidentiary support, written or otherwise, for this claim and
    declined the court's invitation for an evidentiary hearing.                This
    was inadequate, the court concluded.         It stated that there was an
    "insufficient proffer that any such promise of immunity was made
    by a person with actual authority to make it or that Bulger
    detrimentally   relied   upon   such    a   promise,   or     that   any   such
    agreement was enforceable as a matter of law."6
    6 On appeal, Bulger suggests that the trial judge mistakenly
    assumed he intended to assert an all-or-nothing immunity defense
    for the charged crimes, and, according to Bulger, he "never made
    such a claim." The record belies this. The trial judge, in the
    written decision, wrote: "Bulger contends that O'Sullivan gave him
    immunity from prosecution of crimes in this district and that this
    agreement was entered into sometime before December 1984 and ended
    in 1989." This is a completely accurate characterization. In his
    brief to the trial court, Bulger alleged that the immunity
    agreement "bars federal prosecution of the defendant in the
    District of Massachusetts," and the "Dept. of Justice is therefore
    barred from prosecuting the defendant for any crimes that occurred
    prior to 1989." We do not see, and Bulger does not direct us to,
    any points below where he tried to pitch the matter to the court
    any differently. And, of note, Bulger does not actually come out
    and say how he intended to argue immunity, if not in an all-or-
    - 12 -
    The court was also unpersuaded by Bulger's criticism of the
    distinction    the   previous    judge   made   between   historical    and
    prospective immunity.    According to Bulger (again this is just via
    counsel's arguments and representations), the historical versus
    prospective distinction made no sense because the grant of immunity
    was actually "ongoing," in other words it extended from the grant
    in 1984 until the end of O'Sullivan's tenure in 1989.            The court
    saw things otherwise.         It concluded that regardless of whether
    immunity was characterized as prospective, historical, or ongoing
    from its alleged grant, Bulger's proffer was insufficient.
    Finally, the court disposed of Bulger's argument that his
    Sixth    Amendment   rights    were   being   infringed   by   the   court's
    preclusion of his immunity claim, and by extension any testimony
    in support thereof, since though restricted in his testimony,
    Bulger was not actually barred from taking the stand to offer
    pertinent and admissible testimony, and there is no constitutional
    right to introduce irrelevant evidence.
    With the immunity issue decided, the case went to trial.
    Though not precluded from doing so, Bulger ultimately elected not
    to testify.     When questioned by the judge at the close of the
    nothing fashion. He vaguely alludes to his being charged with a
    lot of crimes, and the court's ruling preventing him from
    "presenting an immunity defense for some crimes and relying on the
    government's burden of proof beyond a reasonable doubt of others."
    In any event, Bulger's revisionist view of what happened below
    gets him nowhere.
    - 13 -
    defense's case about whether this election was voluntary, Bulger
    stated: "I'm making the choice involuntarily because . . . I feel
    that I've been choked off from having an opportunity to give an
    adequate defense and explain about my conversation and agreement
    with Jeremiah O'Sullivan.          For my protection of his life, in
    return, he promised to give immunity."            After further lamenting
    the court's decision and the "sham" trial he had received, Bulger
    ultimately confirmed that he had decided not to testify.
    B. Argument
    On appeal, Bulger assigns error to the trial court's pretrial
    immunity ruling. Broadly speaking (more to be said), Bulger argues
    that whether he had immunity was a question solely for the jury
    and should not have been taken up by the judge pretrial.                 The
    judge's doing so, Bulger insists, ran afoul of both Federal Rule
    of Criminal Procedure 12 and the Constitution, specifically the
    protections the latter affords to an accused's rights to have a
    trial     by   jury,   testify,   present    a   defense,   and   not   self-
    incriminate.7     In the alternative, even assuming this was a proper
    pretrial matter, Bulger claims that the judge decided it wrongly
    7 We will dig deeper into Rule 12's provisions later but for now
    it suffices to note that generally the rule sets forth the
    pleadings and pretrial motions procedures in criminal actions.
    Fed. R. Crim. P. 12.     On a side note, Rule 12 was amended in
    December 2014 but "[n]o change in meaning [was] intended." Fed.
    R. Crim. P. 12(b)(1) advisory committee's notes to 2014 amendments.
    As a result, throughout this decision we cite to the 2013 version
    of the rule, which was in effect when this issue was decided below.
    - 14 -
    because his proffer as to the existence of an immunity agreement
    was   sufficient.8   The   government   counters   that   immunity   was
    8 Within his immunity argument, Bulger makes passing reference to
    what is, as best we can tell, a tag-along claim. He argues not
    only that the pretrial ruling was wrong but also that the court
    also should not have, later on in the proceedings, prohibited him
    from testifying about "immunity-related matters," i.e., his
    relationships with DOJ officials, including O'Sullivan.      Bulger
    does not flesh out this argument in his brief; what exactly he is
    talking about only became slightly clearer at oral argument. He
    pointed us generally to a day toward the end of the government's
    case against him where Flemmi, in response to a question from the
    prosecutor, indicated that in connection with his own criminal
    proceedings he initially (and falsely) made some type of
    authorization or immunity claim. Below, defense counsel zeroed in
    on this testimony, suggesting that since the prosecutor asked
    Flemmi about his prior claims of immunity, it somehow opened the
    door to Bulger taking the stand and being asked the same questions.
    The judge disagreed. Bulger did not object to the ruling nor did
    he present a proffer as to what precisely he would have testified
    about. See Fed. R. Evid. 103(a)(2); Fed. R. Crim. Proc. 51(b).
    Without a timely objection, we review Bulger's argument
    (charitably assuming it is crystalized enough) only for plain
    error. United States v. Delgado-Marrero, 
    744 F.3d 167
    , 184 (1st
    Cir. 2014).
    Below defense counsel offered no proffer of Bulger's
    anticipated testimony and did not in any meaningful way explain
    why the testimony had suddenly become relevant, for example to
    rebut the government's claim that Bulger was an informant as he
    now suggests to this court (to be clear, we are not saying that
    such an argument should have carried the day). In light of the
    absence of any worthwhile offering from Bulger, it was reasonable
    for the trial court to conclude, as it did, that the proposed
    testimony would only be relevant insofar as it pertained to the
    issue of immunity. Because the court had already precluded Bulger
    pretrial from raising the immunity issue, and for reasons we will
    get into this decision was correct, the court's decision not to
    allow the testimony can hardly be characterized as an error, plain
    or otherwise. See United States v. Silva-Rosa, 
    275 F.3d 18
    , 23
    (1st Cir. 2001) (finding no error in the court's exclusion of
    testimony that was only relevant to the necessity defense, which
    the court had already properly excluded).
    - 15 -
    correctly taken up pretrial and the judge properly, and without
    impinging on Bulger's rights, precluded Bulger's immunity claim
    based on an insufficient proffer.
    C. Judge vs. Jury
    The first question is whether the judge was right to take up
    the immunity issue pretrial.     The short answer is yes.
    For     one,   our   across-the-board   research   suggests   that
    resolving a defendant's claim that he is immune from prosecution
    pretrial, as opposed to at trial, is more the norm than the
    exception.     See United States v. McLaughlin, 
    957 F.2d 12
    , 15-16
    (1st Cir. 1992) (affirming the trial court's pretrial denial of a
    motion to dismiss an indictment based on immunity); United States
    v. Silvestri, 
    790 F.2d 186
    , 193-94 (1st Cir. 1986) (same); see
    also United States v. Robertson, 
    736 F.3d 1317
    , 1321, 1324-25 (11th
    Cir. 2013) (same); United States v. Fishman, 
    645 F.3d 1175
    , 1184-
    85 (10th Cir. 2011) (same); United States v. Brimberry, 
    744 F.2d 580
    , 586 (7th Cir. 1984)        (holding that "[w]here a defendant
    contends that his or her prosecution is precluded by a grant of
    immunity, a motion to dismiss the indictment is the proper method
    of raising the issue").     And Bulger does not direct us to any case
    law that suggests otherwise.
    What Bulger does contend, however, is that these cases are
    inapposite because they involve instances where the defendant
    sought to have the immunity issue decided pretrial, that is, moved
    - 16 -
    to dismiss the indictment.    Bulger claims that because he, unlike
    those defendants, did not affirmatively seek to have the immunity
    issue decided, it was inappropriate for the court to take up the
    issue at the government's behest.
    For support, Bulger points us to Federal Rule of Criminal
    Procedure 12, which the government cited when it sought the
    pretrial ruling.    The rule provides that "[a] party may raise by
    pretrial motion any defense, objection, or request that the court
    can determine without a trial of the general issue." Fed. R. Crim.
    P. 12(b)(2).      Bulger claims that the plain language of this
    particular subsection, and the corresponding advisory note make
    clear that he can raise an immunity defense at trial without
    seeking pretrial resolution of the issue.     Bulger does not spell
    out why he believes this to be the case.     Our best guess is that
    he is drawing our attention to the permissive "may" in Rule
    12(b)(2) and the corresponding note, which explains that matters
    falling under this provision may, at the defendant's option, be
    raised before trial but failure to do so does not constitute
    waiver.9   Fed. R. Crim. P. 12(b)(1), (2) advisory committee's notes
    to 1944 adoption.     But we fail to see how this is helpful to
    Bulger's cause.    That Bulger may raise immunity pretrial, and that
    9 The next sub-section of the rule sets forth motions that must be
    made before trial, which do not include motions related to
    immunity. Fed. R. Crim. P. 12(b)(3).
    - 17 -
    his failure to do so won't waive the issue, does not necessarily
    mean that he and he alone can raise the issue, or that it was
    improper for the court to consider the government's in limine
    motion.
    Not only does Bulger's argument make little sense but we see
    no legal support for his position.               To start with, it bears noting
    that although Bulger did not file the actual motion seeking
    pretrial resolution, it was he who put the issue into play,
    indicating orally and in a filing before trial that "[t]he defense
    intends to show at trial that James Bulger had immunity for the
    indicted conduct."              As a result, the government, as Rule 12
    permits, requested that the court decide the issue pretrial.                      See
    Fed. R. Crim. P. 12(b)(2) ("A party may raise by pretrial motion
    any defense, objection, or request that the court can determine
    without     a      trial   of    the   general     issue.")    And     immunity   is
    specifically cited as an example of one of those issues that can
    be handled "without a trial of the general issue." Fed. R. Crim.
    P. 12(b)(1), (2) advisory committee's notes to 1944 adoption.                     It
    is logical for this to be so.              Here, there was no need for a full
    jury determination as to Bulger's guilt or innocence because he
    argued      that     the   immunity     agreement     barred     his    prosecution
    regardless of any culpability on his part.
    Simply said, we fail to see why the fact that Bulger was not
    the   one    to     file   the    motion    or   request   the    hearing,    would
    - 18 -
    automatically convert this limited immunity matter to one for the
    jury.    Nothing in Rule 12 itself requires this reading.
    Indeed it would make little sense for the trial judge here,
    when faced with Bulger's clear claim that he was barred from being
    prosecuted in the very courtroom in which he sat, to conduct a
    lengthy trial, only to have the jury potentially find that Bulger
    should not have been prosecuted in the first place.             A judge
    plainly "'should be alerted to the possible superfluity of the
    impending trial so that if the claim proves to have merit the time
    and effort of a trial might be saved.'"         Brimberry, 
    744 F.2d at 586
     (alterations omitted) (quoting United States v. Buonomo, 
    441 F.2d 922
    , 924-25 (7th Cir. 1971)).
    Furthermore, despite Bulger's protestation otherwise, judges
    can effectively make immunity determinations without usurping the
    jury's fact-finding role.10     For one, judges are outfitted to make
    factual findings (they of course do so regularly in varying
    contexts)     and   Rule   12    contemplates     that   some   factual
    determinations might need to be made.           Fed. R. Crim. P. 12(d)
    ("When factual issues are involved in deciding a motion, the court
    must state its essential findings on the record.").      Secondly, our
    10Bulger suggests that there were outstanding issues of fact that
    should have been placed in the hands of a jury, namely whether he
    had immunity, whether O'Sullivan had the authority to grant it,
    and how far the immunity grant could extend.
    - 19 -
    case law suggests that immunity agreements are appropriate fodder
    for the court because, as we have explained in the context of an
    immunity-in-exchange-for-cooperation agreement, such agreements
    "are in the nature of contracts, their scope and effects are
    strongly   influenced   by   contract   law   principles,"   and   the
    defendant's rights under these agreements "are determined by the
    terms and conditions of the bargain as found by the court."
    McLaughlin, 
    957 F.2d at 16
     (emphasis added); see also United States
    v. Dudden, 
    65 F.3d 1461
    , 1469 (9th Cir. 1995) (holding that the
    district court properly refused jury instructions "ask[ing] the
    jury to find whether an informal [immunity] agreement existed");
    United States v. Gerant, 
    995 F.2d 505
    , 510 (4th Cir. 1993) (finding
    the defendant was not entitled to have a jury decide whether he
    breached a non-prosecution agreement because that issue "involves
    the right of the government to prosecute [the defendant] rather
    than [his] guilt or innocence").
    All of this securely undermines the notion that the judge was
    wrong to consider immunity pretrial but a loose end remains.       We
    are still left with Bulger's vague claim that the court's decision
    to take up immunity pretrial violated his constitutional rights,
    namely, his Fifth Amendment right not to incriminate himself, and
    his Sixth Amendment rights to have a trial by jury, present an
    effective defense, and testify.     However, we decline to address
    these claims given that we think Bulger has a preservation problem,
    - 20 -
    which proves dispositive.      While Bulger points generally to some
    cases to support the unarguable notion that the constitutional
    rights he cites are important ones, he does not close the loop.
    He fails to provide us with intelligible analysis, or case law, to
    support his claim that the court's ruling in fact impinged on these
    rights.11
    Of     course   "we   consider   waived   arguments   'confusingly
    constructed and lacking in coherence.'"        Rodríguez v. Mun. of San
    Juan, 
    659 F.3d 168
    , 175 (1st Cir. 2011) (quoting United States v.
    Eirby, 
    515 F.3d 31
    , 36 n.4 (1st Cir. 2008)).        And constitutional
    claims like the ones Bulger lobs are just the type of complicated
    issues that call for some in depth treatment.       See Tayag v. Lahey
    Clinic Hosp., Inc., 
    632 F.3d 788
    , 792 (1st Cir. 2011) ("This is
    11 Bulger's most coherent constitutional argument is that, by
    requiring him to proffer evidence of the alleged immunity agreement
    pretrial, the court violated his Fifth Amendment right against
    self-incrimination. Even were we to suppose this particular claim
    preserved, Bulger loses on the merits. Bulger made this same claim
    below and the trial court disposed of it by invoking Simmons v.
    United States, 
    390 U.S. 377
    , 390 (1968), which the court read to
    bar the government's use of Bulger's potential pretrial statements
    at trial.   On appeal, Bulger says the court's offer of Simmons
    protection rang hollow given the potential derivative use of his
    testimony in other jurisdictions where he may have had criminal
    exposure. We are confused, and consequently unpersuaded, by this
    contention.   Bulger's concern about the derivative use of any
    pretrial proffer does not square with his stated intent to testify
    in open court during trial about the very information the court
    asked for pretrial -- trial testimony which certainly could have
    been used later.
    - 21 -
    hardly a serious treatment of a complex issue and is not adequate
    to preserve the claim on appeal.").12
    There is no need to say more.          With the immunity issue
    properly in the judge's hands, the only question that remains is
    whether she resolved it correctly.
    D. Merits
    As we said, more typically a defendant who contends that an
    immunity grant bars his prosecution would move pretrial to dismiss
    the charges lodged against him.    See McLaughlin, 
    957 F.2d at 15
    ;
    Silvestri, 
    790 F.2d at 193
    .     In instances where the trial court
    has denied the motion and allowed the case to proceed, appellate
    courts assessing a challenge to that ruling have reviewed the trial
    judge's factual determinations about the existence and scope of an
    immunity agreement for clear error.       United States v. Short, 
    387 F. App'x 308
    , 312 (4th Cir. 2010) (reviewing for clear error
    following the district court's denial of a motion to dismiss the
    indictment based on a grant of immunity); United States v. Meyer,
    
    157 F.3d 1067
    , 1078 (7th Cir. 1998) (reviewing the trial court's
    factual determination regarding the scope of an immunity agreement
    for clear error); Silvestri, 
    790 F.2d at 193
     (indicating that the
    12 According to Bulger, the constitutional errors he alleges are
    structural in nature and, therefore, require automatic reversal
    rather than a harmless error analysis. Because we ultimately find
    his arguments waived, and to the extent his Fifth Amendment claim
    is preserved, without merit, we do not need to delve into this
    issue.
    - 22 -
    existence of a plea agreement that purportedly conferred immunity
    on the defendant was a factual determination that could only be
    set aside if clearly erroneous).      We will borrow a page from that
    playbook and do just that here.      In doing so, we find that nothing
    in this record persuades us that the court clearly erred.
    As we explained, the trial judge found the factual record did
    not establish that a legally enforceable promise of immunity was
    made    by   someone   with   authority    to   do   so    or   that   Bulger
    detrimentally relied on any such assurance.               The court was not
    clearly wrong.     There was in essence no proffer from Bulger.           He
    did not offer, say by way of affidavit, particulars of the alleged
    grant, such as when and where it was given, whether anyone else
    was present, whether it was memorialized in some way, or whether
    consideration was exchanged.      The same goes for why immunity was
    supposedly bestowed in the first place.          Bulger did not proffer
    any evidence as to what benefit he heaped on the government in
    exchange for this extensive immunity grant.13         Nor did Bulger make
    a plausible argument that O'Sullivan had actual authority to enter
    13We are still hazy on the precise reason Bulger claims O'Sullivan
    purportedly gave him immunity. He has been vague on this point.
    For instance, in a discovery motion Bulger said the agreement was
    "in return for his assistance with a DOJ objective that did not
    include providing information about others" and that O'Sullivan
    "embraced" this objective. In his colloquy with the trial judge,
    regarding whether he was going to testify, Bulger said his
    protection of O'Sullivan's life was the impetus.
    - 23 -
    into the purported agreement.14   And as for whether Bulger relied
    to his detriment on the alleged promise, perhaps by doing something
    he would not have absent it, Bulger did not say one way or the
    other.   Instead the trial judge was left with a broad, bald
    assertion from defense counsel lacking any particularized details
    that Bulger entered into an immunity agreement with O'Sullivan
    sometime prior to 1984, which barred Bulger's federal prosecution
    in the District of Massachusetts.
    Countering Bulger's rank assertion that he had been granted
    immunity, we had the government's Margolis affidavit (though to be
    clear the burden here is on Bulger, see Flemmi, 
    225 F.3d at 84
    ),
    which unambiguously provided that even assuming the unlikely event
    of O'Sullivan entering into some agreement with Bulger, he would
    not have been authorized to do so.
    Bulger tries to poke holes in the Margolis affidavit, and the
    government's position generally; however, he fails to convince.
    For one, we do not find persuasive Bulger's conclusory challenge
    to the DOJ regulations cited in the Margolis affidavit.15      The
    14 We need not decide whether the supposed immunity grant Bulger
    describes would have been valid if O'Sullivan had the authority to
    enter into it.
    15 The affidavit cites to the DOJ's Principles of Federal
    Prosecution, the Handbook for Prosecution of Racketeers, the
    Guidelines on the FBI Use of Informants and Confidential Sources,
    and a memorandum titled Use of Informants in Domestic Security,
    Organized Crime, and Other Criminal Investigations.
    - 24 -
    regulations,    broadly      speaking,   addressed     how   informants     and
    cooperation agreements were handled in the department.                 Bulger
    says these were simply internal guidelines that did not have the
    force of law and were not binding on DOJ officials at the time of
    this case.     How Bulger reaches these conclusions is not entirely
    clear.   He briefly points us to both 
    28 U.S.C. § 547
    , which vests
    United States Attorneys with the power to prosecute, and he talks
    about the general notion "that the power to prosecute plainly
    includes the power not to prosecute."            Flemmi, 
    225 F.3d at 87
    .
    These observations do not take Bulger far.              That United States
    Attorneys    have    the   general    ability   to   enter     into   immunity
    agreements, hardly means that, one, O'Sullivan did so, two, that
    in this particular instance he had the hierarchal authority to do
    so or, more importantly, that Bulger came close to establishing
    either thing.       Moreover, though internal DOJ regulations do not
    have the same force as the United States Code (a point we can all
    undoubtedly    get    on   board    with),    that   does    not   render   the
    regulations inoperative or irrelevant to the inquiry we find
    ourselves    engaged    in    and   therefore   they    were   appropriately
    factored into the mix below.16
    16 In cursory fashion, Bulger also says that the government's
    contention that O'Sullivan had no authority to bestow immunity is
    irreconcilable with findings this court made in United States v.
    Winter, 
    663 F.2d 1120
     (1st Cir. 1981), abrogated on other grounds
    by Salinas v. United States, 
    522 U.S. 52
     (1997). He claims that
    in Winter -- a race-fixing case involving some of Bulger's
    - 25 -
    Bulger's next contention is likewise unpersuasive.            He argues
    that the lack of any document memorializing the alleged immunity
    agreement -- a fact the Margolis affidavit briefly pointed out --
    should have been given little weight by the trial court in light
    of the evidence showing that law enforcement, at the time, had a
    history of manipulating files and fabricating evidence.17               Even
    putting   aside   that   the   "evidence"   he   cites   is   a   snippet   of
    testimony that came out after the court's pretrial immunity ruling,
    and information that came out in other cases, the court below did
    not appear to give much weight to the fact that no actual document
    memorializing an immunity agreement ever turned up.           Certainly the
    lack of documentation was not stressed or highlighted in its
    analysis.   Rather the court focused on Bulger's failure to satisfy
    cohorts -- this court upheld an informal grant of immunity by
    O'Sullivan. Notwithstanding the fact that Winter tells us nearly
    nothing about the scope of the immunity agreement (an agreement
    the   government   and   cooperating   witness   acknowledged  was
    consummated) or the process the attorney (who went unnamed)
    employed when entering into it, Bulger's read stretches Winter
    well beyond its holding. At most it stands for the proposition
    that United States Attorneys, as a general matter, can enter into
    informal immunity agreements in certain circumstances, see id. at
    1132-35, and we do not conclude otherwise today. Rather we simply
    find that based on the facts of this particular case, Bulger did
    not establish that O'Sullivan entered into an agreement with him
    or that he would have had the authority to do so. Winter is simply
    not helpful to Bulger's cause.
    17 Margolis wrote: "I am advised that a thorough search of the
    records of DOJ and the FBI disclosed no documentation that James
    Bulger was ever actually authorized to engage in any criminal
    activity."
    - 26 -
    his burden of establishing the very existence of an enforceable
    immunity agreement be it written or otherwise.
    And   the    court   was   right     to   do    so.       Despite    repeated
    opportunities, Bulger declined to make a further proffer in support
    of his immunity claim and likewise declined the court's offer of
    an evidentiary hearing to test the Margolis affidavit.                     Bulger
    took a calculated risk, choosing this course based on a strident
    belief that the court was not authorized to decide the matter
    pretrial, but, as we said above, that belief was misguided.                   Faced
    with the scarcity of evidence offered by Bulger, and the Margolis
    affidavit, we cannot say that the court clearly erred in finding
    the evidence did not establish the existence of a valid and binding
    immunity agreement.
    That facet of the appeal decided, we soldier on.
    III. THE MARTORANO CONCERNS
    Bulger      next   presents    a   series      of     arguments   that    John
    Martorano,    Bulger's     former       Winter      Hill     compatriot    turned
    government witness, sits at the center of.               We chart the relevant
    background before proceeding to the arguments' particulars.
    A. Background
    As the reader now knows, Martorano cut a deal.                    He started
    negotiating with the government back in 1998, ultimately admitting
    to involvement in twenty murders, twelve of which stemmed from his
    Winter Hill days.         He pled guilty to ten (federally charged)
    - 27 -
    murders, some other federal crimes, and two state murder charges.
    In exchange for his guilty pleas, and his agreement to cooperate
    in   the   prosecution     of    Bulger,   Flemmi,       and   any    corrupt    law
    enforcement members, Martorano walked away with just a fourteen-
    year sentence plus five years' supervised release and by the time
    of Bulger's trial, he was a free man.               The information Martorano
    provided ended up leading to murder charges against Bulger, Flemmi,
    Bulger's FBI handler Connolly, and another FBI agent, Paul Rico.
    Fast forward to October of 2012, when, about eight months
    before Bulger's trial got underway, the government received an
    anonymous letter. The letter alleged that Martorano (who of course
    was a slated trial witness) was presently engaged in illegal
    gambling     activities    and    that     his     law    enforcement     handler,
    Massachusetts     State    Police    Lieutenant          Stephen     Johnson,    was
    impeding any attempts to investigate or prosecute this behavior.
    The government filed an ex parte motion with the court alerting it
    to the letter and indicating that an investigation would follow.
    The investigation was completed by the State Police, which
    detailed its findings in an extensive written report, a few months
    later.     The government informed the court of the end result, which
    was that after interviewing a number of witness and reviewing
    various exhibits, the investigators concluded that the anonymous
    letter's     allegations   leveled       against    Lieutenant       Johnson    were
    unfounded.     The court granted a protective order for the anonymous
    - 28 -
    letter, which prevented anyone else, including Bulger, from seeing
    it.
    A few months later, and about a month before trial, the
    government alerted the defense to the allegations that Martorano
    was gambling illegally and provided reports from some of the
    investigation's interviews, including interviews with Martorano
    and other involved individuals, which basically contained denials
    of any wrongdoing.18   It did not provide the State Police's final
    investigative report or the anonymous complainant's letter.
    A few weeks after that (and the day before jury selection)
    Bulger filed a motion, pursuant to Federal Rule of Criminal
    Procedure 16 and Brady v. Maryland, 
    373 U.S. 83
     (1963), seeking
    all   materials   related   to   accusations   of   Martorano's   ongoing
    criminal conduct and Lieutenant Johnson's supposed shielding of
    Martorano from investigation.      According to Bulger, the materials
    could be exculpatory and any investigative forbearance exercised
    by law enforcement towards Martorano -- that is, Johnson protecting
    Martorano and insulating his criminal activity -- would constitute
    a promise, reward or inducement that should have been disclosed.
    Bulger then filed a second motion seeking the full transcript of
    the interview with the anonymous complainant, who had turned out
    18During trial, defense counsel questioned Martorano regarding the
    allegations and he again denied any wrongdoing, indicating that he
    simply gambled with a friend at a casino.
    - 29 -
    to be Massachusetts State Police Trooper Nunzio Orlando.19         He also
    sought to stay the start of trial until these issues were resolved.
    The trial judge reviewed the anonymous letter (Judge Stearns
    had reviewed it the first time around) and the State Police
    investigative report, which taken together we will refer to as the
    ex parte materials.      After doing so, the court issued an oral
    ruling.
    The court, which noted that a "full-fledged investigation"
    had been undertaken by the State Police, found that the government
    was not legally required to turn over materials related to the
    tipster's allegations against Lieutenant Johnson since they "were
    determined to be not just unsubstantiated . . . but, quote, false
    and not factual."    The court further found that, even if true, the
    allegation that Johnson was protecting Martorano would only be
    relevant if Martorano knew about this perk and there was no
    suggestion that he had any such knowledge.           As for Martorano's
    alleged   illegal    gambling   itself,    the   court   noted   that    the
    government had turned over documents to the defense related to
    those allegations.    After the court delivered its ruling, defense
    counsel then questioned whether he would be allowed to call Trooper
    Orlando   (the   formerly   anonymous     complainant    who   spurred   the
    19It is unclear precisely when it became known that Orlando was
    the complainant.    The government in its brief to this court
    suggests that Bulger's attorneys had their own sources of
    information regarding Orlando's complaint.
    - 30 -
    illegal    gambling   investigation)    as    a   witness       and    the   court
    indicated that it would have to the give the question some further
    thought.
    With   the   issue   resolved   (at    least    as   to    the    ex   parte
    materials), trial got underway and, as planned, Martorano was
    called by the government to testify about Bulger's criminal past.
    Not surprisingly, the deal he struck with the government also came
    up.   Martorano's 1998 plea agreement was entered into evidence,
    and he was questioned by both the prosecution and defense about
    his plea negotiations, along with the criminal conduct that put
    Martorano in the spot he was in.       More on the specifics later, but
    for now it suffices to note that some of the questioning had to do
    with which of his criminal cohorts Martorano was required to
    provide information about, or testify against, pursuant to his
    plea deal.
    Meanwhile, as the trial plodded on, the parties quibbled over
    potential witnesses. As we said, the judge had left open the issue
    of whether Trooper Orlando could testify.            With the issue still up
    in the air, Bulger went ahead and placed Orlando on his trial
    witness list.      Citing various rules of evidence, the government
    moved to preclude Orlando as a witness, along with others related
    to the gambling investigation, arguing that they were being called
    simply to rehash the false accusations.
    - 31 -
    The court agreed.       In a ruling from the bench, it precluded
    Orlando from testifying, indicating that there was no basis for
    admitting his testimony since the cover-up allegation had been
    debunked.     And assuming the defense wanted to impugn Martorano's
    credibility     with   the    testimony        about    the     illegal   gambling
    allegations (as opposed to the supposed cover-up itself), the judge
    opined that such evidence would be inadmissible under Federal Rule
    of   Evidence   608.    See    Fed.    R.   Evid.      608(b)    (providing   that
    generally speaking "extrinsic evidence is not admissible to prove
    specific instances of a witness's conduct in order to attack or
    support the witness's character for truthfulness").
    With the stage set, we proceed to the arguments Bulger makes
    on appeal.
    B. Martorano's Ongoing Criminal Conduct
    Bulger remains unhappy with the court's restrictive decisions
    relative to the supposed cover-up of Martorano's ongoing criminal
    gambling conduct.      He argues that he was entitled to the ex parte
    materials (the anonymous letter and State Police investigative
    report) under Brady and, hence, the court's decision to deny him
    access to the materials was in error.            For the same reasons Bulger
    assigns error to that decision, Bulger also takes exception to the
    court precluding Trooper Orlando from testifying.20                The government
    20 Bulger's argument almost solely focuses on the exclusion of
    Orlando as a witness.      However, he briefly mentions, and
    - 32 -
    stands by the adequacy of its disclosure, arguing that it was not
    required to turn over evidence relative to unfounded allegations
    of investigative forbearance.    And given that Orlando could only
    testify about disproven allegations, he was properly excluded.
    i. Ex Parte Materials
    As to Bulger's access to the ex parte materials, "[w]e review
    a district court's Brady determinations after its in camera review
    for an abuse of discretion."      United States v. López-Díaz, 
    794 F.3d 106
    , 116 (1st Cir. 2015); United States v. Caro-Muñiz, 
    406 F.3d 22
    , 29 (1st Cir. 2005).
    Brady dictates that the government must "disclose 'evidence
    favorable to an accused' that is 'material either to guilt or to
    punishment.'" United States v. Cruz-Feliciano, 
    786 F.3d 78
    , 87
    (1st Cir. 2015) (quoting Brady, 
    373 U.S. at 87
    ); see also Giglio
    v. United States, 
    405 U.S. 150
    , 150-51, 154-55 (1972) (requiring
    the government to disclose evidence of a promise it made to a
    witness).   Favorable could mean exculpatory or impeaching in
    nature, and material means "a reasonable probability that, had it
    criticizes, the judge's decision to preclude as witnesses Neil
    Cherkas and Dominic Masella, two Martorano associates whose names
    came up in connection with the gambling investigation and who
    Bulger identified as potential witnesses. Because Bulger failed
    to develop this argument in any meaningful way, we deem it waived
    and focus (as he does) on Orlando. See Mazariegos v. Lynch, 
    790 F.3d 280
    , 285 n.5 (1st Cir. 2015) (providing that failure to
    develop an argument waives it).
    - 33 -
    been disclosed, the result of the proceeding would have been
    different." Cruz-Feliciano, 786 F.3d at 87.
    Bulger contends that the ex parte materials qualify because
    investigative forbearance that inured to Martorano's benefit,
    which Bulger claims occurred, would not only call into question
    Martorano's   credibility   but    would   fit   squarely   within   the
    defense's theory that the government was heaping benefits on
    potential witnesses to secure certain convictions.          Said another
    way, Bulger thinks the ex parte materials were impeaching in nature
    in the sense that they might affect the "jury's estimate of the
    truthfulness and reliability of" Martorano, which could have meant
    the difference here between acquittal and conviction.         Conley v.
    United States, 
    415 F.3d 183
    , 189 (1st Cir. 2005) (quoting Napue v.
    Illinois, 
    360 U.S. 264
    , 269, (1959)).21
    21Bulger's focal point, both as to the ex parte materials and the
    possible testimony of Trooper Orlando, is its potential to show
    that the government was heaping a benefit on Martorano by allowing
    his criminal activity to go unchecked, which might call his
    credibility into question. Bulger does not appear to argue that
    any tangential evidence of the alleged illegal gambling itself,
    which might be contained in the materials, or spoken to by Orlando,
    was relevant for that same purpose. To the extent he is, which we
    doubt and in any event would be an underdeveloped argument, it is
    not a particularly persuasive position.     For starters, like we
    said above, the government turned over documents connected to the
    illegal gambling allegations themselves. To the extent Bulger was
    hunting for more, that evidence would be inadmissible, see Fed. R.
    Evid. 608(b) (providing, except in circumstances not relevant
    here, that "extrinsic evidence is not admissible to prove specific
    instances of a witness's conduct in order to attack or support the
    witness's character for truthfulness"), which would cause problems
    not only for Orlando's testimony but also for the ex parte
    - 34 -
    The theory Bulger floats necessarily requires a couple of
    things.     Johnson must have been complicit in ignoring some sort of
    illegal gambling on Martorano's part, and Martorano must have been
    aware that Johnson was looking the other way. The problem is this.
    As    the   trial   court   found     after   reviewing   the   ex   parte
    materials -- and which our review confirms -- the allegations of
    impermissible protection leveled against Lieutenant Johnson were
    debunked.     Specifically, the ex parte materials made clear that
    the    Massachusetts     State      Police    conducted   an    extensive
    investigation, which included a number of interviews, along with
    evidence gathering and analysis. After all this, the investigators
    concluded that the allegations aimed at Johnson were deemed, as
    the court reported below, "false and not factual."          And even had
    some untoward behavior on Johnson's part been discovered, there
    was no indication or even suggestion that Martorano knew what
    Johnson was purported to be up to.
    This being the state of things, we cannot conclude that the
    court abused its discretion in holding that Bulger was not entitled
    to the ex parte materials under Brady or Giglio (or any of their
    progeny) and, as a result, in declining to stay the trial.           See,
    materials as well. See DeCologero v. United States, 
    802 F.3d 155
    ,
    162 (1st Cir. 2015) ("Withheld information is material under Brady
    only if it would have been admissible at trial or would have led
    to admissible evidence.").
    - 35 -
    e.g., United States v. Souffront, 
    338 F.3d 809
    , 823 (7th Cir. 2003)
    (finding    that   "[t]he   failure    to    disclose     untrustworthy   and
    unsubstantiated allegations against a government witness is not a
    Brady violation"); United States v. Ray, 
    61 F. App'x 37
    , 54 (4th
    Cir. 2003) (finding that the government's delayed disclosure of a
    statement did not violate Brady because the statement was "sheer
    speculation"); United States v. Locascio, 
    6 F.3d 924
    , 949 (2d Cir.
    1993) (affirming the district court's conclusion that no Brady
    violation    occurred   because,      in    part,   the   newly    discovered
    government reports contained "untrustworthy" allegations).
    Orlando's     allegations,    which     Bulger     supposed   were   both
    favorable and material, were disproven and allowing him to rummage
    through the ex parte materials would have been just the type of
    fishing exhibition that our jurisprudence does not contemplate.
    See Caro-Muñiz, 
    406 F.3d at 29
     ("Brady does not permit a defendant
    to conduct an in camera fishing expedition through the government's
    files.") (internal quotation marks omitted).              The court did not
    abuse its discretion in denying Bulger access to the materials.
    That signals the end of this issue, but we think the following
    bears mention.      To be clear, our conclusion today by no means
    suggests that the government can sidestep its Brady obligations
    simply by conducting its own investigation and determining that
    potentially discoverable allegations are unsubstantiated.                 Our
    holding is limited to the facts of this case.               Here, the court
    - 36 -
    conducted an in camera review of a significant amount of ex parte
    materials,   following   a    comprehensive   internal   State     Police
    investigation, which, by all indications, was conducted in the
    ordinary course in response to a complaint lodged against one of
    its officers.   The court reviewed not only the final investigative
    report, and the conclusions contained therein, but more impartial
    documents, including interview summaries and excerpts.           Based on
    these, the court concluded, and our review confirmed, that not
    only were the allegations dubious and unsupported but they were
    false and not factual.       Given all this, plus the absence of any
    indication that the police investigation was conducted in bad faith
    or skewed to reach a certain result, we cannot find that the
    court's Brady ruling was an abuse of discretion.
    ii. Excluded Witness
    Similarly the court did not abuse its discretion in precluding
    Trooper Orlando from testifying.      See United States v. Occhiuto,
    
    784 F.3d 862
    , 867 (1st Cir. 2015) (providing that a district
    court's denial of a defendant's request to call a witness engenders
    abuse-of-discretion review).      Orlando's testimony, Bulger says,
    was further evidence of the government's charitable investigative
    forbearance and therefore had the impeaching potential to impugn
    Martorano's credibility.     But, as explained above, the allegations
    of a cover-up on Johnson's part were disproven and, therefore, any
    testimony Orlando could offer relative to the issue would have
    - 37 -
    been irrelevant and highly prejudicial.          See Fed. R. Evid. 402
    ("Irrelevant evidence is not admissible."); Fed. R. Evid. 403 ("The
    court may exclude relevant evidence if its probative value is
    substantially outweighed by a danger of . . . unfair prejudice.").
    With the proffered testimony failing to hit the essential
    prerequisites for admissibility, the court's decision to exclude
    it falls comfortably within its broad discretionary power to
    exclude evidence.        United States v. Maldonado-García, 
    446 F.3d 227
    , 231-32 (1st Cir. 2006) (explaining that "district courts enjoy
    wide latitude in passing upon the relevancy of evidence"); United
    States v. Norton, 
    26 F.3d 240
    , 243 (1st Cir. 1994) ("The district
    court is vested with broad discretionary power to admit or exclude
    evidence.").
    We will not further belabor the point.           This aspect of the
    appeal disposed of, we continue on to Bulger's other Martorano-
    based argument.
    C. Martorano's Side Deal
    As we mentioned earlier, Martorano was asked on the stand
    about which of his cohorts he was expected to provide information
    about,   or    testify     against,   pursuant   to    his   plea   deal.
    Additionally, Massachusetts State Trooper Thomas Foley, who spent
    much of his career investigating organized crime in Boston and who
    also testified at Bulger's trial, was asked about his understanding
    of Martorano's deal with the government.         To this court, Bulger
    - 38 -
    homes in on this testimony from Martorano and Foley.                But bear
    with us because his argument is hard to describe, hard to follow,
    and difficult to square with the legal framework that he attempts
    to fit it into.
    As best we can tell, Bulger claims that the testimonies
    Martorano and Foley gave in an entirely different case (a Florida
    state case against Connolly, Bulger's FBI handler), which defense
    counsel had Martorano and Foley read into the record during
    Bulger's trial, establish that the government made a favorable
    promise   to   Martorano    when    negotiating    his    plea     agreement.
    Specifically, in Bulger's opinion, the testimony reveals that the
    government made some sort of side deal or off-the-books promise to
    Martorano that he would never be required to testify against his
    family or close friends, namely, his brother, James Martorano, or
    friends Howie Winter and Pat Nee, who all had ties to Winter Hill.
    This side deal, Bulger argues, was a benefit the government heaped
    on Martorano that could have been impeaching in nature as it would
    have cast doubt on his veracity.
    Accordingly   Bulger    makes    a   couple   of    claims.    One,   the
    government was required to disclose the supposed off-the-books
    promise as impeachment evidence under Brady.                And, two, the
    prosecutor acted improperly by engaging in what Bulger suggests
    were cagey lines of questioning that obfuscated the alleged back
    door promise and allowed Martorano to testify falsely about who he
    - 39 -
    was obligated to testify against.22     The government denies any
    wrongdoing but pays little attention to Bulger's Brady argument,
    instead focusing on the false testimony piece.      On that front,
    according to the government, its examination of Martorano produced
    only accurate information about who and what he was required to
    testify about pursuant to his plea agreement.   Regardless, we take
    up both pieces of Bulger's claim.
    i. Disclosure of an Agreement
    The lack of accord between how the parties treat this issue
    might stem from something we noted at the start of this side-deal
    discussion: it is difficult to fit Bulger's argument into the legal
    framework in which one typically finds a Brady failure-to-turn-
    over-evidence claim.   See United States v. Agurs, 
    427 U.S. 97
    ,
    107-08 (1976) (explaining the typical contexts in which Brady
    claims arise).
    The problem is a very basic one.   We have no Brady decision
    to review. By his own admission, when the purported non-disclosure
    arose at trial, Bulger never asked the judge to decide whether an
    off-the-books promise existed or whether any Brady violation had
    22Bulger tacks on another "example of the prosecution's distortive
    practices" in his reply brief, claiming that the government
    repeatedly tried to elicit statements from FBI agent John Morris
    that contradicted testimony he gave in another case. Since this
    argument made its first appearance in the reply brief, we dispatch
    of it as waived. Soto-Padró v. Pub. Bldgs. Auth., 
    675 F.3d 1
    , 8
    (1st Cir. 2012).
    - 40 -
    occurred.   This was so despite all of the evidence on which he now
    relies -- Martorano's and Foley's Florida testimony -- being
    available at trial.   Left with no decision from the trial court,
    we have no way to employ the abuse of discretion review that we
    would normally apply to a trial court's Brady decision.     United
    States v. Celestin, 
    612 F.3d 14
    , 22 (1st Cir. 2010); Caro-Muñiz,
    
    406 F.3d at 29
    .
    This being the state of things, we are left perplexed as to
    what Bulger expects us to do with his claim of Brady error and he
    does nothing to clear up this confusion.   Bulger provides us with
    no case law to support the notion that it is proper for us to take
    up this issue in the first instance, and no law that would shed
    any light on how such an inquiry might go.    Left in the dark, we
    decline to venture any farther.   Whether you characterize Bulger's
    Brady claim as unpreserved because he did not seek a ruling below,
    or waived for failure to adequately develop it on appeal, his claim
    fails.   See, e.g., Mazariegos v. Lynch, 
    790 F.3d 280
    , 285 n.5 (1st
    Cir. 2015) (providing that undeveloped arguments devoid of legal
    support are waived on appeal); Murray v. United States, 
    704 F.3d 23
    , 32 n.10 (1st Cir. 2013) (suggesting, in connection with a writ
    of coram nobis petition, that the petitioner's failure to timely
    raise a Brady claim below might waive the issue).
    - 41 -
    ii. The Prosecutor's Questioning
    That leaves us with the prosecutor's questioning, and whether
    it brought out, or left uncorrected, false testimony about who
    Martorano was required to testify against.
    Courts have long held that prosecutors may not knowingly
    present false evidence, including false testimony, or allow it to
    go uncorrected when it happens.         Giglio, 
    405 U.S. at 153
    ; Napue,
    
    360 U.S. at 269
    ; United States v. Flores-Rivera, 
    787 F.3d 1
    , 31
    (1st Cir. 2015). Based on the record before us, we cannot conclude
    that this is what happened here.
    First,    we    disagree    that   the   prosecutor,   in    actuality,
    represented,    or    elicited   testimony,    that   Martorano    would   be
    compelled to testify against his friends and family, as Bulger
    maintains.     The prosecutor's lines of inquiry Bulger that points
    to were not directed at whether Martorano was bound to testify,
    but whether he had provided truthful information about all of the
    individuals he was asked about.           And the questioning that did
    pertain to his testimonial obligations accurately pointed out in
    what instances Martorano had to testify.         This included a list of
    targeted individuals, which on its face (and as the questioning
    bore out), did not include James Martorano, Winter, or Nee.
    Second, Martorano's and Foley's Florida testimony -- the
    record evidence Bulger cites as establishing this supposed side
    - 42 -
    deal that the prosecutor was obfuscating and allowing Martorano to
    testify falsely about -- was hardly conclusive.
    For example, at defense counsel's urging, Foley read from the
    transcript of his Florida testimony the following: "At the time we
    were working on the case, realistically, John Martorano was not
    going to testify against those individuals."       Assuming "those
    individuals" refers to some combination of James Martorano, Winter
    and Nee, this sounds more like a general observation on Foley's
    part as opposed to a firm indication that an actual agreement to
    that effect existed.    The Florida testimony that followed (again
    Foley read this into the record), "I suppose it was part of an
    agreement that his attorney made with the U.S. Attorney's Office,"
    is equivocal at best.   And when he was asked, in the Florida case,
    whether the state police were on board with the agreement Foley
    "suppose[d]" existed, he said: "Unfortunately, we were put in a
    situation where we had to agree to that."     The problem here is
    that not only was Foley further expounding on a supposition, but
    he later clarified that his understanding of Martorano's deal came
    from the proffer period before Martorano's agreement with the
    government was finalized.
    Martorano's testimony, also yanked from the Florida state
    case and read into the record below, was no more helpful.23    For
    23 Defense counsel had Martorano read the Florida testimony into
    the record after Martorano, on the stand below, thrice responded
    - 43 -
    example, in the Florida case, Martorano was asked about having
    told the government that James was with him during one murder and
    whether "part of the plea agreement was that couldn't be used
    against you," to which Martorano answered, "[p]ositively."                     He
    responded the same when asked: "So that's something else you got
    from the government?"          The exchange is hard to follow but at most
    seems to suggest that James's crime could not be used against
    Martorano.          And when asked, "[s]o part of the deal included
    protection for your brother, James Martorano, right?" (again we
    are    still    talking    about    the     Florida    testimony),     Martorano
    answered, "[s]ure." This testimony is probably the most supportive
    of Bulger's position (at least as to a James-based side deal) but
    we scarcely think it is enough.             The response is inexact, as is
    the nature of the protection.
    We can hardly say that these vague snippets, plucked out of
    context      from    another    trial,     establish    that    the    prosecutor
    elicited, or allowed to go uncorrected, false testimony about the
    bargain Martorano and the government struck.                And when we consider
    the integration clause in Martorano's plea agreement, providing
    that   the     written    agreement      contained    the   complete    and   only
    agreement between the parties, and the government's consistent
    "[n]o" when asked whether he thought he could protect his brother
    James, Winter, and Nee respectively.

    claim that it produced all Brady materials pretrial, Bulger's
    position becomes even more untenable.
    While we do not need to go any further, the following is worth
    a mention.   A "conviction obtained by the knowing use of perjured
    testimony is fundamentally unfair, and must be set aside if there
    is any reasonable likelihood that the false testimony could have
    affected the judgment of the jury."          Agurs, 
    427 U.S. at 103
    (footnote omitted); see also Mastracchio v. Vose, 
    274 F.3d 590
    ,
    601 (1st Cir. 2001).    Here the jury heard all about the litany of
    incentives built into Martorano's plea agreement and his sweeping
    criminal past.     In other words, they had plenty of reasons to
    question his veracity.      It is hard to see how one additional
    enticement would have upended the jury's estimate of Martorano's
    credibility.
    With that said, we plow on.
    IV. PROSECUTOR'S SPEAKING OBJECTIONS
    Bulger's final argument focuses on the prosecutor's continued
    use of prolonged speaking objections during the trial. Bulger
    maintains that the objections saturated the jury with improper and
    inadmissible evidence and opinions.      The government, for its part,
    does not deny engaging to some extent in the verbose practice,
    but, it insists, the judge intervened when needed and ensured that
    both sides gave a balanced and fair presentation of the evidence.
    - 45 -
    A. Background
    At the final pretrial conference the judge cautioned both
    sides: "In terms of objections, you know, object with a word or
    two if you think its necessary and citation to the rule, but
    otherwise, no speaking objections. If I need any more, I'll ask
    for it."   Despite the judge's stated preference, the government
    sometimes ran afoul of this directive. For example, the prosecutor
    was heard to say things like: "Objection, this is badgering," or
    "And I object. There is no good-faith basis for that question, and
    Mr. Brennan knows that."    And (among others) there was: "I object
    to that, that's an incorrect statement of the law."         Despite
    repeated admonishment from the judge, both in front of the jury
    and at sidebar, the prosecutor's practice continued.
    B. Analysis
    Assuming favorably to Bulger that his claim of error is
    preserved, our review of whether there was any prosecutorial
    misconduct is de novo.24   United States v. Sepúlveda-Hernández, 
    752 F.3d 22
    , 31 (1st Cir. 2014).     If we conclude such misconduct did
    occur, we then consider the prejudice piece, that is, "whether the
    24The government contends that Bulger's claim is at best partially
    preserved because he did not formally object to all of the speaking
    objections. And although he did move for a mistrial based in part
    on the speaking objections, he never renewed that motion even
    though the government continued with its verbose practice. Given
    that Bulger did object on multiple occasions to the speaking
    objections, including moving for a mistrial, we will go ahead and
    assume the objection preserved.

    prosecutor's behavior so poisoned the well that the defendant must
    be given a new trial."     United States v. Vázquez-Botet, 
    532 F.3d 37
    , 56 (1st Cir. 2008) (internal quotation marks omitted). Factors
    include: "the egregiousness of the conduct; the context in which
    it occurred; whether the court gave curative instructions and what
    effect these instructions likely had; and the overall strength of
    the Government's case."    
    Id.
    We have some doubts that the prosecutor's use of speaking
    objections amounted to prosecutorial misconduct, but even assuming
    it did, we cannot conclude that the conduct so poisoned the well
    as to warrant a new trial.
    First, the conduct is plainly not that egregious.     Sure the
    record shows that the prosecutor did not faithfully adhere to the
    court's request for clipped objections, but to say, as Bulger does,
    that counsel was misleading the jury or inserting improper evidence
    is a stretch.     Most of the objections Bulger points to involve
    proper quibbles with the basis for defense counsel's question.
    For example, there was: "And I object. There is no good faith basis
    for that question, and Mr. Brennan knows it."    The judge sustained
    this objection.      Or there was: "Objection.   That's not a fair
    characterization."    The judge responded by asking defense counsel
    to rephrase.    As we have said, "[c]ounsel should not be held to
    standards of perfection," Sepúlveda-Hernández, 752 F.3d at 32, and
    the objections here were not so beyond the pale.     Second, though
    - 47 -
    Bulger points to a fair amount of speaking objections, we are
    required to place them in context.       The objections were made over
    the course of a lengthy trial and, as the trial judge noted,
    attorneys on both sides managed to work in some animated commentary
    while questioning or objecting.
    Third, while the court gave no curative instructions, Bulger
    did not request any.     And the court did give plenty of general
    instructions about trial protocol.       On the first day of trial, the
    judge explained the concept of objections to the jury.       The judge
    indicated that a "lawyer may object," which "simply means that the
    lawyer's requesting that I make a decision on a particular rule."
    She clarified: "Statements and arguments by the attorneys are not
    evidence.     The    lawyers   are   not    witnesses."     Similarly,
    "[o]bjections are not evidence."         The judge repeated the same
    sentiment in the charge to the jury at the close of the case, and
    we presume the jury to have followed all of these instructions.
    See United States v. Gentles, 
    619 F.3d 75
    , 82 (1st Cir. 2010) ("It
    is a well established tenet of our judicial system that juries are
    presumed to follow such instructions.").
    Finally, the government's case was not a weak one.             It
    introduced numerous witnesses and exhibits all pointing towards
    Bulger's guilt.     Given all this, we have no trouble concluding
    that even had the speaking objections constituted misconduct,
    Bulger was not prejudiced.

    V. CONCLUSION
    For the reasons spelled out above, Bulger got a fair trial
    and none of the complained-of conduct on the court or government's
    part warrant reversal of his conviction.25   We affirm.
    25 In the interest of completeness, we note that Bulger raised a
    claim of cumulative error.      Because we find no merit to the
    individual claims, as a matter of course there can be no cumulative
    error. United States v. Brown, 
    669 F.3d 10
    , 28 (1st Cir. 2012).
