    March 25, 2019
    KAYATTA,    Circuit     Judge.       A    jury    found     Francisco
    Martínez-Mercado guilty of conspiracy to deprive a person of civil
    rights in violation of 
    18 U.S.C. § 241
    .              The district court then
    sentenced him to eighty-seven months in prison.                       On appeal,
    Martínez-Mercado     challenges      the    sufficiency      of   the   evidence
    against him, the admission of evidence under Federal Rule of
    Evidence 404(b), the exclusion of certain testimony, the denial of
    his new-trial motion based on newly discovered evidence, and the
    appropriateness of his sentence.             For the following reasons, we
    affirm.
    I.
    Although we review the facts relevant to Martínez-Mercado's
    sufficiency challenge in the light most favorable to the government,
    we also "provide a more or less neutral summary" of the facts relevant
    to his remaining claims and reserve further exposition of those facts
    for our later analysis.       See United States v. Flores-Rivera, 
    787 F.3d 1
    , 9 (1st Cir. 2015).
    The events underlying Martínez-Mercado's conviction took
    place in September of 2010.          At that time, Martínez-Mercado was
    working as a Task Force Officer ("TFO") for the Bureau of Alcohol,
    Tobacco, Firearms and Explosives ("ATF"). He had previously worked
    in   the   Drugs   Division    of   the    Puerto    Rico    Police   Department
    ("PRPD"), where Jorge Fernández had been his supervisor.                     The
    alleged conspiracy included PRPD officers Pedro López-Torres and
    - 2 -
    Luis Ramos-Figueroa, both of whom eventually cut a deal and
    testified on behalf of the government.
    At trial, López-Torres testified that on September 15,
    2010, Fernández told López-Torres that Martínez-Mercado was "going
    to do a job in the area[] of Carolina" and "need[ed] help in doing
    that job."   Fernández and López-Torres had worked illegal "jobs"
    together in the past, and López-Torres was conveniently serving in
    the Property Division of the Carolina Criminal Investigations Unit
    at the time. Based on Fernández's assurances that Martínez-Mercado
    was trustworthy, López-Torres eventually agreed to take a call
    from   Martínez-Mercado.    Martínez-Mercado   called   López-Torres
    almost immediately, and they arranged to meet in person to discuss
    the job.
    That same day, López-Torres contacted Ramos-Figueroa,
    "[b]ecause he was the person that [López-Torres] trusted to do
    . . . illegal jobs."   The two met up to talk about the potential
    job in Carolina.   Ramos-Figueroa agreed to participate in whatever
    scheme might unfold.
    Days later, López-Torres and Martínez-Mercado met at a
    gas station to go over the details of the plan.         According to
    López-Torres, Martínez-Mercado said he had hired "some thugs,
    meaning street criminals," to break into an apartment to steal
    "money, jewelry and controlled substances, drugs."         Martínez-
    Mercado explained that the apartment belonged to someone who had
    - 3 -
    recently been arrested by ATF.           López-Torres agreed to provide
    "security" and "communication" using his police patrol car and
    radio.    López-Torres testified that he used his patrol car on jobs
    so "that people would believe that a legal activity was being
    conducted there by the police."             Additionally, if he heard a
    complaint come in over the radio, he would warn his co-conspirators
    and attempt to divert any potential investigation.
    On September 23, Martínez-Mercado called López-Torres to
    tell him that they would execute the plan that evening.              López-
    Torres relayed the information to Ramos-Figueroa.             While López-
    Torres was on duty, he met up with Martínez-Mercado at around
    7:00 p.m. in the parking lot of a local supermarket.                Ramos-
    Figueroa joined them shortly thereafter.           Martínez-Mercado was
    driving   a    mini-van,   and   both   López-Torres   and   Ramos-Figueroa
    testified that they could see the silhouettes of at least two other
    people in the back of the van.
    Following a signal from Martínez-Mercado, López-Torres
    and Ramos-Figueroa drove out of the parking lot in López-Torres's
    patrol car and trailed the van to the PlayaMar condominium complex.
    López-Torres parked at the end of the street, while the van
    remained in front of the building.          They watched as two or three
    people jumped out of the van and entered the complex.                López-
    Torres and Ramos-Figueroa kept their eyes on the van and listened
    - 4 -
    to the police radio.         After they saw the van's interior lights
    turn on, they left the area.
    When López-Torres and Martínez-Mercado reconvened as
    planned, Martínez-Mercado handed López-Torres about $3,000 to
    split with Ramos-Figueroa.        Martínez-Mercado explained that "there
    wasn't that much" in the apartment, just "about $6,000 to $7,000
    and some jewelry."
    López-Torres spoke with Martínez-Mercado over the phone
    several     times    over   the   next   week.     During    one    of     those
    conversations,      López-Torres    informed     Martínez-Mercado        that   a
    complaint had been filed the day after the break-in.               The morning
    of   September 24,      another     officer,     Josue    Cosme-Rosa,       took
    photographs of the "ransacked" PlayaMar apartment and concluded
    that the balcony door had likely been forced open.
    The district court allowed the government to introduce
    so-called     "bad     acts"      evidence     under     Federal     Rule       of
    Evidence 404(b), over objection, through the testimony of two
    other former PRPD officers, Rafael Ramos-Veléz and Miguel Pagán.
    The government also presented telephone records and historical
    cell-site data.       This evidence confirmed that Martínez-Mercado,
    Fernández, and López-Torres had been in contact by phone on
    September 15 and showed nineteen calls between Martínez-Mercado
    and López-Torres on the night of the Carolina job.            The cell-site
    - 5 -
    data also showed that Martínez-Mercado's and López-Torres's cell
    phones were in the area of the PlayaMar that night.
    Near the end of the case against him, Martínez-Mercado
    alleged that the government delayed the production of an FBI
    report, which detailed an interview with another PRPD officer,
    Yaritza Cruz-Sánchez, who had investigated the PlayaMar complaint.
    The district court determined that, although the report was not
    disclosed until the day before trial, it was not exculpatory or
    impeaching under Brady v. Maryland, 
    373 U.S. 83
     (1963).    The court
    did not permit the introduction of the report and also denied
    Martínez-Mercado's request to issue a material-witness warrant for
    Cruz-Sánchez.
    Martínez-Mercado takes issue with two further district
    court actions during the presentation of his case.        First, the
    district court excluded the testimony of ATF Agents Jean Carlos
    Rivera and Julio Torres about an ATF investigation that Martínez-
    Mercado contends would have accounted for his communications with
    Fernández and López-Torres.   After hearing the agents' testimony
    outside the presence of the jury, the court concluded that they
    did not have any relevant information.      Second, although the
    district court allowed Fernández to testify, the court advised him
    of his Fifth Amendment rights three times, and Fernández invoked
    his right against self-incrimination in response to questioning on
    cross-examination.
    - 6 -
    On February 26, 2016, after a five-day trial, the jury
    found    Martínez-Mercado        guilty    of    conspiring    to   violate        civil
    rights. The district court denied his renewed motion for acquittal
    under    Federal    Rule   of    Criminal       Procedure 29    and    subsequently
    denied each of his new-trial motions pursuant to Federal Rule of
    Criminal Procedure 33.
    II.
    A.
    Martínez-Mercado appeals the denial of his motions for
    judgment of acquittal based on the insufficiency of the evidence.
    See Fed. R. Crim. P. 29(a).           We review a district court's denial
    of a Rule 29 motion de novo, asking "whether, after assaying all
    the evidence in the light most amiable to the government, and
    taking     all    reasonable     inferences       in   its    favor,    a    rational
    factfinder       could   find,    beyond    a    reasonable     doubt,       that    the
    prosecution successfully proved the essential elements of the
    crime."    United States v. George, 
    841 F.3d 55
    , 61 (1st Cir. 2016)
    (quoting United States v. Chiaradio, 
    684 F.3d 265
    , 281 (1st Cir.
    2012)).
    A   section 241      conspiracy      exists     when     "two    or    more
    persons conspire to injure, oppress, threaten, or intimidate any
    person . . . in the free exercise or enjoyment of any right or
    privilege secured to him by the Constitution or laws of the United
    States."     
    18 U.S.C. § 241
    .        In this case, the federal right at
    - 7 -
    issue is the right to be free from unreasonable searches and
    seizures under the Fourth Amendment.                Accordingly, to convict
    Martínez-Mercado,      the    government       needed   to     prove    beyond     a
    reasonable    doubt    that    he     "1) conspired     to   injure,     oppress,
    threaten,    or   intimidate    [the    victim],     2) with    the    intent    to
    interfere with the victim's [Fourth Amendment] rights, 3) under
    color of [Commonwealth] law."          United States v. Cortés-Cabán, 
    691 F.3d 1
    , 13 (1st Cir. 2012) (quoting United States v. Guidry, 
    456 F.3d 493
    , 507 (5th Cir. 2006)); see also United States v. Lebron-
    Gonzalez, 
    816 F.2d 823
    , 829 (1st Cir. 1987) ("Although section 241
    does not specify a 'color of law' requirement, the Fourteenth
    Amendment requires it."        (citing United States v. Price, 
    383 U.S. 787
    , 799 (1966))).
    Martínez-Mercado argues that the conspirators did not
    act under color of law.        He also argues that, even if they did act
    under color of law, there could be no Fourth Amendment violation
    without more evidence from an identifiable victim.                     We address
    these two arguments in turn.
    1.
    Martínez-Mercado's        primary      argument     is    that      the
    government    failed   to     prove    that    he   conspired     to    commit    a
    constitutional violation "under color of law." In truth, Martínez-
    Mercado's complaint seems to be that the alleged conspiracy was
    never to orchestrate an illegal seizure under color of law; rather,
    - 8 -
    the plan was for a band of hired "thugs" -- unmistakably private
    actors -- to break into the condominium and steal valuables inside.
    To be sure, Martínez-Mercado does not suggest that the mere
    involvement of private individuals precludes prosecution under
    section 241, as any such argument would inevitably prove futile.
    See Price, 
    383 U.S. at 794
     ("Private persons, jointly engaged with
    state officials in the prohibited action, are acting 'under color'
    of law for purposes of [section 241]."); United States v. Aponte-
    Sobrado, 
    847 F. Supp. 2d 316
    , 319–20 (D.P.R. 2012).                  Nor can he
    successfully argue that his failure to conceive of the heist in
    constitutional terms provides any defense.                     Screws v. United
    States, 
    325 U.S. 91
    , 106 (1945) (making clear that "[t]he fact
    that the defendants may not have been thinking in constitutional
    terms is not material where their aim was . . . to deprive a
    citizen    of   a   right    and     that    right   was   protected    by     the
    Constitution").
    Still, the "acts of officers in the ambit of their
    personal   pursuits    are   plainly        excluded"   from    liability    under
    section 241.    
    Id. at 111
    .        "[P]rivate conduct, outside the line of
    duty and unaided by any indicia of actual or ostensible state
    authority, is not conduct occurring under color of state law."
    Martinez v. Colon, 
    54 F.3d 980
    , 986–87 (1st Cir. 1995).                Although
    courts have had frequent occasion to interpret section 1983's
    "color of law" requirement, "there is no bright line test for
    - 9 -
    distinguishing 'personal pursuits' from activities taken under
    color of law."    Pitchell v. Callan, 
    13 F.3d 545
    , 548 (2d Cir.
    1994); see also Price, 
    383 U.S. at
    794 n.7 (noting that, in section
    1983 cases, "'under color' of law has consistently been treated as
    the same thing as the 'state action' required under the Fourteenth
    Amendment").   We have previously instructed that a state actor
    does not act under color of law unless his "conduct occurs in the
    course of performing an actual or apparent duty of his office, or
    unless the conduct is such that the actor could not have behaved
    in that way but for the authority of his office."     Martinez, 
    54 F.3d at 986
    ; see also United States v. Classic, 
    313 U.S. 299
    , 326
    (1941) ("Misuse of power, possessed by virtue of state law and
    made possible only because the wrongdoer is clothed with the
    authority of state law, is action taken 'under color of' state
    law.").
    More specifically, this court trains its attention "on
    the nature and circumstances of the officer's conduct and the
    relationship of that conduct to the performance of his official
    duties."   Martinez, 
    54 F.3d at 986
    .     "The key determinant is
    whether the actor . . . purposes to act in an official capacity or
    to exercise official responsibilities pursuant to state law." Id.;
    see also Barreto-Rivera v. Medina-Vargas, 
    168 F.3d 42
    , 45 (1st
    Cir. 1999) ("While certain factors will clearly be relevant -- for
    example, a police officer's garb, an officer's duty status, the
    - 10 -
    officer's use of a service revolver, and the location of the
    incident -- these factors must not be assessed mechanically.");
    Parrilla-Burgos v. Hernandez-Rivera, 
    108 F.3d 445
    , 449 (1st Cir.
    1997)    (listing   the   same   factors).       Martínez-Mercado    argues,
    therefore, that the conspiracy at issue here did not involve
    conduct committed in the performance of any actual or pretended
    official duty.
    The facts show otherwise.           The conspirators literally
    employed the colors of the law in the form of a marked on-duty
    police vehicle to do what no private individual could do -- divert
    private and police interlopers by creating the appearance of
    legitimate police involvement.          The plan also addressed the risk
    of a citizen call to the police by exploiting López-Torres's
    official capacity to forestall any investigation at the scene.
    López-Torres and Ramos-Figueroa were part of the conspiracy and
    present at the scene of the heist precisely because they possessed
    the     official    authority    to    ensure    that   it   would   proceed
    uninterrupted.      This was surely enough to support a jury finding
    that the conspirators acted under color of law.          See United States
    v. Hatch, 
    434 F.3d 1
    , 4 (1st Cir. 2006) (noting that in deciding
    a sufficiency challenge courts "must only satisfy [themselves]
    that the guilty verdict finds support in a plausible rendition of
    the record").
    - 11 -
    2.
    Martínez-Mercado also argues that the government failed
    to prove a Fourth Amendment violation because it did not identify
    any actual victim who had a "reasonable expectation of privacy" in
    the PlayaMar condominium.          See Katz v. United States, 
    389 U.S. 347
    ,   360    (1967)    (Harlan,   J.,      concurring).        Certainly,    the
    government needed to show that the conspirators tried to violate
    some person's right to be free from an unlawful search and seizure.
    But the government did this.             It presented evidence that the
    condominium was a home, and a locked one at that.               It also put in
    evidence that Martínez-Mercado knew that the home belonged to a
    recently arrested person. As the U.S. Supreme Court has explained,
    "[w]ithout question, the home is accorded the full range of Fourth
    Amendment protections."       Lewis v. United States, 
    385 U.S. 206
    , 211
    (1966).      There is simply no blanket requirement that the victim
    testify.       See     Cortés-Cabán,     691   F.3d   at   13    (noting     that
    "circumstantial evidence will suffice" to establish the elements
    of a conspiracy).        The government presented sufficient evidence
    for the jury to reasonably infer that Martínez-Mercado conspired
    to violate the Fourth Amendment rights of whoever lived in the
    targeted apartment.
    B.
    Martínez-Mercado next argues that the district court
    misinterpreted the scope of Federal Rule of Evidence 404 and then
    - 12 -
    improperly admitted the testimony of two government witnesses
    under   that     rule.          Although    we    review     the   district      court's
    application of Rule 404 for abuse of discretion, when there is an
    allegation that "the district court misapprehended the scope of
    the Rules it was applying," we review its legal interpretations de
    novo.    United States v. Gilbert, 
    229 F.3d 15
    , 20–21 (1st Cir.
    2000); Olsen v. Correiro, 
    189 F.3d 52
    , 58 (1st Cir. 1999) ("The
    proper interpretation of the Federal Rules of Evidence is a
    question of law and is reviewed de novo.").
    Rule 404 dictates that "[e]vidence of a crime, wrong, or
    other act is not admissible to prove a person's character in order
    to   show   that       on   a   particular       occasion    the   person      acted     in
    accordance with the character."                  Fed. R. Evid. 404(b)(1).               But
    Rule 404    also       specifies    that     evidence       of   prior    acts    may    be
    admissible to prove "motive, opportunity, intent, preparation,
    plan,   knowledge,          identity,      absence    of     mistake,     or     lack    of
    accident."       Fed. R. Evid. 404(b)(2).             We have formulated a two-
    part    test     for    determining        the    admissibility      of    Rule 404(b)
    evidence.       First, a court must determine whether the evidence has
    some "special relevance" independent of its tendency to show
    criminal propensity.            United States v. Rodriguez-Barrios, 
    573 F.3d 55
    , 64 (1st Cir. 2009) (citing United States v. Aguilar-Aranceta,
    
    58 F.3d 796
    , 798 (1st Cir. 1995)).                   Second, if the evidence has
    some such relevance, the court must then decide whether its
    - 13 -
    probative value is substantially outweighed by the danger of unfair
    prejudice.     
    Id.
       And probative value "must be considered in light
    of the remoteness in time of the other act and the degree of
    resemblance to the crime charged."        United States v. Frankhauser,
    
    80 F.3d 641
    , 648 (1st Cir. 1996) (quoting United States v. Fields,
    
    871 F.2d 188
    , 197 (1st Cir. 1989)).
    The district court allowed two government witnesses --
    PRPD officers Pagán and Ramos-Veléz -- to testify, over repeated
    defense objections, about two prior uncompleted conspiracies that
    allegedly involved Martínez-Mercado.         The government summarized
    that evidence as follows in its pretrial notice of intent to
    introduce evidence of other bad acts:
    1.   In or about December of 2010, [while
    defendant was employed as a TFO for ATF],
    defendant, along with other Puerto Rico police
    officers entered a conspiracy to steal money
    and/or drugs from a house located in Santurce,
    San Juan, Puerto Rico, under color of
    law. . . . The plan included staying outside
    the location while other individuals entered
    the house dressed as police officers to
    conduct the robbery. Their contingency plan
    included identifying themselves as [PRPD
    officers] from the Criminal Investigations
    Division . . . .
    2.   On a date unknown, but while defendant
    was employed as a TFO for ATF, defendant
    entered a conspiracy with at least one known
    Puerto Rico police officer to steal money
    and/or drugs from a house in Carolina, Puerto
    Rico, under color of law.
    - 14 -
    Both plots were ultimately abandoned.     At trial, Pagán
    testified that the first plot involved the execution of an "illegal
    warrant" and that he was charged with staying "in front of the
    house with the police patrol car."   Ramos-Veléz confirmed that the
    first plot also contemplated the presence of a "marked patrol car."
    The only relevant testimony as to the second plot was that Ramos-
    Veléz and Martínez-Mercado called it off after they noticed that
    the house in Carolina was armed with security cameras.
    The government argued to the district court that its
    evidence of the two prior conspiracies was admissible "to show
    that the Defendant had a common scheme or plan" that "involved
    conducting robberies of homes . . . and that he hired other police
    officers to . . . assist him in their marked patrol units or, as
    a contingency plan, should they be detected either by an owner of
    the apartment or by somebody in the vicinity of the area, to secure
    the success of the operation."     Accordingly, the district court
    admitted that evidence as proof of a "common scheme or plan."
    But the proffered bad acts did not reveal "a continuing
    or connected scheme" linking the prior alleged conspiracies to the
    instant conspiracy.    United States v. Lynn, 
    856 F.2d 430
    , 435 (1st
    Cir. 1988); see also United States v. Varoudakis, 
    233 F.3d 113
    ,
    119 (1st Cir. 2000).    Rather, Pagán's and Ramos-Veléz's testimony
    showed several such plans, rather than a single common scheme or
    plan.
    - 15 -
    The government alternatively argues that the evidence
    was "specially relevant" to prove Martínez-Mercado's intent.                      The
    government, though, does not articulate how Martínez-Mercado's
    alleged participation in arranging the two uncharged conspiracies
    is relevant to whether he had the requisite intent to conspire to
    interfere with a known federal right in this case.                        See United
    States    v.    Guest,    
    383 U.S. 745
    ,   760    (1966)    (noting    that   the
    conspiracy charge requires proof of "specific intent").                     Although
    this   court     has     maintained     that   when    bad     acts    evidence    "is
    introduced to show knowledge, motive, or intent, the Rule 404(b)
    exceptions . . . have been construed broadly," United States v.
    Flores Perez, 
    849 F.2d 1
    , 4 (1st Cir. 1988), we need be cautioned
    that "the relevance of a prior conviction admitted to prove
    'intent' . . . may rest on little more than propensity," United
    States v. Henry, 
    848 F.3d 1
    , 15 (1st Cir. 2017) (Kayatta, J.,
    concurring).        In    this   case,   it    is    difficult    to    escape    such
    propensity-based         reasoning.       As     Martínez-Mercado       avers,    the
    government's evidence of bad acts broadly highlighted his alleged
    past corrupt associations with fellow police officers, inviting
    the jury to generalize this bad behavior into "bad character and
    [to] tak[e] that as raising the odds that he did the later bad act
    now charged."          Old Chief v. United States, 
    519 U.S. 172
    , 180
    (1997).    This is precisely what the rule seeks to avoid.
    - 16 -
    The government also arguably suggests that the evidence
    established Martínez-Mercado's "identity" or "modus operandi" by
    highlighting       the   similarity        between     the   prior        acts    and   the
    September 2010 Carolina job.                   For Rule 404(b) evidence to be
    admitted to prove modus operandi, the government must show "a high
    degree of similarity between the other act and the charged crime."
    United States v. Trenkler, 
    61 F.3d 45
    , 52 (1st Cir. 1995) (citing
    United States v. Ingraham, 
    832 F.2d 229
    , 231–33 (1987)).                                The
    government     "must      demonstrate          that   the    two    acts     exhibit      a
    commonality of distinguishing features sufficient to earmark them
    as the handiwork of the same individual."                          
    Id.
     at 53 (citing
    Ingraham, 
    832 F.2d at 231
    ).                    Moreover, under Federal Rule of
    Evidence 104(b), district courts must condition the admission of
    modus   operandi         evidence        "on    a     showing      that     the    shared
    characteristics of the other act and the charged offense are
    sufficiently idiosyncratic that a reasonable jury could find it
    more likely than not that the same person performed them both."
    
    Id.
       In resolving whether the evidence supports an inference that
    the incidents are "sufficiently idiosyncratic," the inquiry "must
    focus   on   the    'totality       of    the    comparison,'       demanding       not   a
    'facsimile or exact replica' but rather the 'conjunction of several
    identifying    characteristics            or    the    presence      of    some    highly
    distinctive quality.'"         Id. at 54 (quoting Ingraham, 
    832 F.2d at
    232–33).
    - 17 -
    The government points to the use of a marked patrol car
    parked outside the location of the planned heist as such a "highly
    distinctive quality."    Of course, that identifying feature was
    said to be present in only one of the two prior conspiracies.    As
    to that conspiracy, the testimony did indeed describe a plan to
    park a patrol vehicle outside the location to be robbed.    But the
    plan as described otherwise markedly differed from the heist that
    gave rise to this prosecution, most notably because it involved
    the use of "an illegal warrant."     Nor was there any participation
    of private individuals or even a break-in.      As Pagán explained:
    "We were just going to appear there and knock that door down, go
    inside the house and arrest the woman, take . . . whatever she had
    there."   Given the differences, it is as if the government were
    pointing to the use of a ball in both a cricket match and a baseball
    game as proof of modus operandi for a particular player.    There is
    a common factor but not one that is so unusual and distinctive as
    to make two otherwise quite different methods of operation appear
    to be the mark of a single person.    See Ingraham, 
    832 F.2d at 233
    ;
    see also United States v. Pisari, 
    636 F.2d 855
    , 859 (1st Cir. 1981)
    ("The single fact that in committing a robbery, one invokes the
    threat of using a knife falls far short of a sufficient signature
    or trademark upon which to posit an inference of identity.").    We
    cannot say, therefore, that the prior bad acts were "specially
    - 18 -
    relevant" as evidence of modus operandi.       For these reasons, the
    admission of the prior bad acts was erroneous.
    Nevertheless,   we   hold     that   the   district   court's
    erroneous admission of the bad acts evidence was harmless.        While
    we once again underscore "the folly of bad act overkill," United
    States v. Arias-Montoya, 
    967 F.2d 708
    , 714 (1st Cir. 1992), in
    this case we can determine "with fair assurance . . . that the
    judgment was not substantially swayed" by the district court's
    error, Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946); see
    also United States v. Hicks, 
    575 F.3d 130
    , 143 (1st Cir. 2009)
    ("We   review    non-constitutional       evidentiary    errors     for
    harmlessness; an error is harmless if it is 'highly probable that
    the error did not influence the verdict.'"     (quoting United States
    v. Roberson, 
    459 F.3d 39
    , 49 (1st Cir. 2006))).         The cell phone
    records and location information corroborated the central gist of
    the cooperators' testimony.    It confirmed the initial contacts
    between the conspirators, and it solidly placed Martínez-Mercado
    in the neighborhood of the home invasion in repeated communications
    with López-Torres without any conceivable innocent explanation.
    We therefore decline to hold that the admission of the Rule 404(b)
    evidence was prejudicial error.
    C.
    Martínez-Mercado further claims that the district court
    violated his rights under the Sixth Amendment's Compulsory Process
    - 19 -
    Clause and the Fourteenth Amendment's Due Process Clause in three
    ways.   First, he argues that the district court undermined his
    right to present a meaningful and complete defense by excluding
    the testimony of two ATF agents.      Second, he contends that the
    court erroneously ruled that the government's production of an FBI
    302 Report on the eve of trial detailing an interview with Officer
    Yaritza Cruz-Sánchez was not a Brady violation.       The court then
    compounded that error, Martínez-Mercado claims, by refusing to
    authorize a material-witness warrant for Officer Cruz-Sánchez and
    by excluding the 302 Report itself.       Lastly, Martínez-Mercado
    asserts that the court intimidated Jorge Fernández by repeatedly
    advising him of his Fifth Amendment rights.
    1.
    Martínez-Mercado first complains that the district court
    excluded the proffered testimony of two ATF agents.    In support of
    his proffer, Martínez-Mercado represented that the agents would
    testify that Martínez-Mercado was tasked with investigating an ATF
    cooperating witness in an unrelated matter.   That task, he argued,
    gave him a perfectly legitimate reason to be communicating with
    Fernández and López-Torres on September 15 because they might have
    "worked with this confidential informant before."         But one of
    Martínez-Mercado's   proffered   witnesses    indicated    that   the
    investigation of the cooperator did not commence until after the
    cooperator's arrest on September 20. And the other witness offered
    - 20 -
    no alternative chronology. In light of that chronological mismatch
    between the asserted theory or relevance and the actual testimony,
    the district court sensibly concluded that the testimony was not
    reasonably capable of establishing the relevant point Martínez-
    Mercado hoped to establish.              We see no reason to upset that
    determination.     See Pike v. Guarino, 
    492 F.3d 61
    , 78 (1st Cir.
    2007)   ("Although       the     right    to     present    a     defense       is   of
    constitutional dimension, it is not absolute."                     (citing Nix v.
    Whiteside, 
    475 U.S. 157
    , 173 (1986))); United States v. Brandon,
    
    17 F.3d 409
    , 444 (1st Cir. 1994) (noting that the district court
    has "broad discretion in making relevancy determinations").1
    2.
    Martínez-Mercado           advances    several       related   arguments
    concerning the trial court's treatment of a so-called 302 Report
    summarizing   an   FBI    interview      with    PRPD   officer     Cruz-Sánchez.
    During the interview, Cruz-Sánchez stated that (1) a person other
    than the owner of the condominium first called in the burglary;
    and   (2) López-Torres         told   Cruz-Sánchez      that     "they    had    taken
    material (referring to drugs) and money" from the apartment.
    Martínez-Mercado argues on appeal that the late production of this
    1Martínez-Mercado argues on appeal that even with the September 20
    arrest date, he might have started investigating the witness before
    his arrest. But he did not make this argument at trial, so plain
    error review applies, see United States v. Sánchez-Berríos, 
    424 F.3d 65
    , 78 (1st Cir. 2005), and there is no clear error because
    his proffered testimony does not clearly back up this theory.
    - 21 -
    report (on the eve of trial) was a Brady violation and that the
    court should have admitted the report into evidence or compelled
    Officer Cruz-Sánchez to testify.
    The    district        court     viewed       the   report      as    largely
    irrelevant    and     at     best      marginally      impeaching       on    collateral
    matters.      We     see   no    unreasonableness           in   that   determination.
    Martínez-Mercado does not attempt to explain how who reported the
    burglary is even relevant to his defense.                    He claims only that it
    "refuted the testimony of Josue Cosme-Rosa," who did testify that
    "the complainant himself . . . gave [the PRPD] access [to the
    parking lot]."       Cosme-Rosa's testimony, however, had nothing to do
    with who reported the break-in.               It is not clear that the identity
    of the initial complainant is at all material to Martínez-Mercado's
    defense.
    The    district        court     also    aptly      explained        away   any
    superficial    inconsistency           between       the    302 Report       and    López-
    Torres's     trial     testimony.           That     is,     although     López-Torres
    testified that Martínez-Mercado told him that only money and
    jewelry    were      taken      from    the    apartment,        López-Torres        never
    testified as to his own knowledge of what was stolen.                              Besides,
    the fact that López-Torres told Officer Cruz-Sánchez that drugs
    were taken from the apartment does not suggest, as Martínez-Mercado
    claims,    that    López-Torres         "planned       or    executed     the      crime."
    Moreover, as the district court observed, evidence as to how the
    - 22 -
    robbery was carried out would have been irrelevant to Martínez-
    Mercado's defense because he was charged with a conspiracy offense
    that does not require an overt act by him.              See United States v.
    Crochiere, 
    129 F.3d 233
    , 234, 238–39 (1st Cir. 1997) (holding that
    
    18 U.S.C. § 241
     does not require an overt act in furtherance of
    the conspiracy).
    Our    conclusion    that    the      district     court   reasonably
    assessed    the    proffered    evidence     as    at   best      marginally    and
    collaterally relevant dooms Martínez-Mercado's trio of arguments.
    We review the denial of a new-trial motion on the basis of an
    alleged Brady violation for manifest abuse of discretion.                 United
    States v. Morales-Rodriguez, 
    467 F.3d 1
    , 14 (1st Cir. 2006).                    And
    there is no Brady violation compelling a new trial when the
    belatedly supplied evidence is merely cumulative or impeaching on
    a collateral issue.         Conley v. United States, 
    415 F.3d 183
    , 189
    (1st Cir. 2005).      Similarly, we review for abuse of discretion a
    decision    to    exclude   evidence    as   cumulative      or    insufficiently
    relevant.    Brandon, 
    17 F.3d at 444
    .             And there is no such abuse
    when the evidence is at once both cumulative and relevant only
    arguably to contradict other evidence on peripheral issues.                    Id.2
    2 From our conclusion that these evidentiary rulings were not an
    abuse of discretion, it follows that the district court's exclusion
    of   Sánchez-Cruz's   testimony   and   the  302 Report   was   not
    constitutional error.
    - 23 -
    3.
    Martínez-Mercado's      witness-intimidation          claim    also
    fails.3   The district court properly advised Fernández of his Fifth
    Amendment rights.     See United States v. Santiago-Becerril, 
    130 F.3d 11
    , 26 (1st Cir. 1997) ("A judge is entitled to make sure a
    witness understands [his] Fifth Amendment rights.").             The district
    court rightly noted that it did not "actively encourage[] a witness
    not to testify or badger[] a witness into remaining silent."
    United States v. Arthur, 
    949 F.2d 211
    , 216 (6th Cir. 1991).
    Martínez-Mercado    takes    particular    issue    with   the    fact   that,
    although the court first read the witness his rights outside the
    presence of the jury, the judge subsequently "informed Fernández
    of his ability to invoke his 'rights' on no less than three
    occasions."    It is obvious from the trial transcript, however,
    that the witness became confused and needed clarification of the
    judge's proper warning.        The court had little choice but to
    instruct him further.       What's more, as the district court found,
    Fernández "testified fully" for Martínez-Mercado on direct and
    only invoked his right to remain silent during parts of the
    government's   cross-examination.          United   States   v.    Martínez-
    Mercado, No. CR 15-576 (FAB), 
    2016 WL 8674489
    , at *11 (D.P.R.
    June 17, 2016).     The district court did not inhibit Martínez-
    3 In his post-trial motions, Martínez-Mercado framed this issue as
    a judicial-bias claim.
    - 24 -
    Mercado's right to present a meaningful defense.
    D.
    Martínez-Mercado next argues that the district court
    abused its discretion by denying his second new-trial motion based
    on newly discovered evidence.          See Fed. R. Crim. P. 33.       We review
    the   denial   of   a     new-trial     motion     for   "manifest    abuse    of
    discretion."   United States v. Carpenter, 
    781 F.3d 599
    , 608 (1st
    Cir. 2015) (citing United States v. Wright, 
    625 F.2d 1017
    , 1019
    (1st Cir. 1980)).       A court may grant a motion for a new trial based
    on newly discovered evidence if
    (1) the evidence was unknown or unavailable to
    the   defendant   at   the  time   of   trial;
    (2) failure to learn of it was not because of
    lack of due diligence; (3) the evidence is
    material, and not merely cumulative or
    impeaching; and (4) it will probably result in
    acquittal upon retrial.
    Carpenter, 781 F.3d at 621 (citing Wright, 
    625 F.2d at 1019
    ); see
    also United States v. Hernández-Rodríguez, 
    443 F.3d 138
    , 143 (1st
    Cir. 2006) ("[W]e have no discretion to grant a motion for a new
    trial if any one of the four factors is lacking.").                  Since both
    sides agree that the first two prongs of the so-called Wright test
    are satisfied, we address only the latter two.
    On   December 16,      2016,       the   government   disclosed     two
    additional FBI 302 Reports summarizing information provided by
    Metropolitan Detention Center inmates Arnaldo López-Ortiz and
    Osvaldo Vasquez-Ruiz.        Martínez-Mercado argues in his brief that
    - 25 -
    these reports, as well as a subsequent telephone interview with
    Nadab Arroyo-Rosa (another federal inmate), suggest that López-
    Torres and Ramos-Figueroa "(1) coordinated fraudulent testimony
    designed     to   secure   the    conviction    of     Mr.    Martínez-Mercado;
    (2) testified      falsely       and    fraudulently         at   [trial];   and
    (3) deliberately misled prosecutors during debriefings."                     The
    district court concluded that Martínez-Mercado failed to establish
    that the newly discovered evidence was material as required by the
    third prong.      United States v. Martínez-Mercado, 
    261 F. Supp. 3d 293
    , 306 (D.P.R. 2017).
    New evidence is "material" when "it has the potential
    'to alter the outcome of the lawsuit under applicable legal
    tenets.'"    United States v. Hernández-Rodríguez, 
    443 F.3d 138
    , 145
    (1st Cir. 2006) (quoting Roche v. John Hancock Mut. Life Ins. Co.,
    
    81 F.3d 249
    , 253 (1st Cir. 1996)).          Newly discovered evidence that
    is merely impeaching, however, "normally cannot form the basis for
    a new trial."         United States v. Colón-Muñoz, 
    318 F.3d 348
    , 361
    (1st Cir. 2003) (quoting United States v. Bonadonna, 
    775 F.2d 949
    ,
    957 (8th Cir. 1985)).       Martínez-Mercado counters that "[t]he value
    of the evidence was not simply to show that López-Torres and Ramos-
    Figueroa were generally liars and perjured themselves in the past,"
    but   that    "[i]t    demonstrated      they   were   actively     fabricating
    testimony in this case in order to receive a sentence reduction."
    - 26 -
    The   reports    summarize    the   inmates'   claim   that   they
    overheard the two cooperating conspirators in this case (López-
    Torres and Ramos-Figueroa) talking about coordinating testimony.
    According    to      the   inmates,    López-Torres    and   Ramos-Figueroa
    discussed "getting a story straight" having to do with a firearm
    and the possibility that cameras might show them to be someplace
    on some occasion other than where they claimed to be.              One inmate
    allegedly mentioned that if the prosecutors found out that López-
    Torres and Ramos-Figueroa were concocting a false story, the "other
    guy" (presumably, thought the FBI agents, the person against whom
    López-Torres and Ramos-Figueroa were going to testify) would walk.
    The government was unable to provide any further information about
    the context in which these broad statements were made or when the
    conversation took place.       Martínez-Mercado further argues that one
    of   the   inmates    "specifically     confirmed   that   López-Torres   and
    Ramos-Figueroa discussed concocting false and fraudulent testimony
    on one or more occasions."
    The materiality of the newly discovered evidence depends
    on whether a jury would probably presume that López-Torres and
    Ramos-Figueroa were discussing Martínez-Mercado's case in a manner
    that suggests perhaps a frame.         The district court answered in the
    negative, and we find no abuse of discretion in that determination.
    Although, as Martínez-Mercado notes, the district court conceded
    that "[t]he information in the 302 reports suggest[s] that López-
    - 27 -
    Torres and Ramos-Figueroa concocted testimony," Martínez-Mercado,
    261 F. Supp. 3d at 305, the court never stated that the "concocted
    testimony" related to this case.          On this point, Martínez-Mercado
    asserts that, "López-Torres and Ramos-Figueroa did not testify at
    any other trials or in-court legal proceedings."               But nothing in
    the reports suggests that the reference to "testimony" was limited
    to trial testimony in this case, as opposed to statements provided
    to FBI agents and prosecutors in other cases. Further, the reports
    describe the conversation as covering a withheld firearm and
    cameras   at      various   locations,    significant    details   that     have
    nothing at all to do with this case.
    For purposes of this appeal, we can nevertheless assume
    without deciding that the proffered evidence was "material," and
    not irrelevant or merely impeaching.           That assumption brings us to
    the fourth prong:       Would the evidence "probably" have altered the
    result?      We    think    not.   As    we   have   already   explained,    the
    government's case against Martínez-Mercado was not reasonably
    vulnerable to an enhanced credibility attack on the cooperating
    witnesses.     It is undisputed that the break-in occurred and that
    the cell phone evidence placed Martínez-Mercado both in timely
    repeated communication with López-Torres and in the area of the
    crime without any suggestion in the record that either of them had
    any legitimate reason to be there (much less talking to one
    another) at that time.         There was no testimony at trial about any
    - 28 -
    camera or firearm.    And, had there been, we see no reasonable
    likelihood that any such evidence could be viewed as exculpatory.
    The evidence contained in the 302 reports and corroborated by
    Arroyo-Rosa's interview was not "sufficiently compelling that it
    would probably result in an acquittal."       United States v. Alicea,
    
    205 F.3d 480
    , 487 (1st Cir. 2000).
    E.
    Finally, Martínez-Mercado argues that his sentence was
    procedurally unreasonable.     The court below calculated a total
    offense level of twenty-seven and a criminal history category of
    I, resulting in a guidelines range of seventy to eighty-seven
    months, and sentenced Martínez-Mercado to eighty-seven months in
    federal prison.    We review sentencing decisions for abuse of
    discretion,   examining   findings    of   fact   for   clear   error   and
    interpretations of the sentencing guidelines de novo.              United
    States v. Flores-Machicote, 
    706 F.3d 16
    , 20 (1st Cir. 2013).
    The district court correctly calculated a base offense
    level of seventeen by referencing U.S.S.G. § 2B2.1 pursuant to
    U.S.S.G § 2H1.1(a)(1), which instructs the court to apply the
    offense guideline applicable to any underlying offense.         Here, the
    conduct underlying Martínez-Mercado's conviction for conspiring to
    violate civil rights was burglary of a residence, so U.S.S.G.
    § 2B2.1(a)(1) dictated a base level of seventeen.
    - 29 -
    The district court increased the base level by six levels
    under U.S.S.G. § 2H1.1(b)(1), which applies when the defendant
    "was a public official at the time of the offense" or "the offense
    was committed under color of law." For the reasons we have already
    explained,    there   was   no   error   in    finding   the   terms   of   that
    enhancement satisfied.
    Under U.S.S.G. § 3B1.1(a), the district court increased
    the base level by an additional four levels because "the defendant
    was an organizer or leader of a criminal activity that involved
    five or more participants."        The government presented evidence at
    trial demonstrating that the alleged conspiracy involved Martínez-
    Mercado, Fernández, López-Torres, Ramos-Figueroa, and at least two
    "thugs."      And,    contrary   to    Martínez-Mercado's      assertions    on
    appeal, the amended presentence report reflected as much.                   The
    district court did not abuse its discretion at sentencing.
    III.
    Finding the evidence sufficient to sustain Martínez-
    Mercado's conviction, and finding no other reversible error, we
    affirm the conviction and sentence.
