    Hon. David H. Souter, Associate Justice (Ret.) of the
    Supreme Court of the United States, sitting by designation.
    LIPEZ, Circuit Judge. Appellant Terrance Moon challenges
    his conviction for being a felon in possession of a firearm and
    ammunition, in violation of 18 U.S.C. § 922(g)(1), on numerous
    evidentiary grounds. He also challenges his sentence under the
    Armed Career Criminal Act ("ACCA").            Finding no merit to any of
    these challenges, we affirm.
    I.
    A. Factual Background
    The following facts are undisputed. On February 5, 2011,
    Detective Michael Ross obtained search warrants for Moon's person
    and an apartment at 99 Ormond Street in Boston.           In his supporting
    affidavit,     Ross   stated    that,    based    on   information    from    a
    confidential informant ("CI") who previously purchased heroin from
    Moon,    the   Boston   Police       Department   ("BPD")   had      conducted
    surveillance of three recent controlled buys by this CI from Moon,
    including one within the "last seventy-two hours."                Ross stated
    that during that most recent transaction, Moon was spotted driving
    a green Mercedes that was registered to Sherrica Hendricks, his
    longtime     girlfriend,   at   99    Ormond   Street,   Apartment     #1,   in
    Mattapan.1
    1
    Ross also stated that he had intentionally avoided including
    details about past investigations in which the CI had provided
    reliable information to preserve the BPD's ability to work with
    informants and protect the CI from harm. He explained that
    providing identifying information about past investigations would
    allow persons to build a "pyramid" in an attempt to identify the
    -2-
    The next day, officers arrived at 99 Ormond Street to
    execute the search warrants. Detective Ross and Sergeant Detective
    Paul Murphy observed Moon exit 99 Ormond Street, walk down the
    street to meet with an unknown individual, and return to the
    building.      The officers approached Moon, read him his Miranda
    rights and searched his person, recovering, among other things, a
    set of keys.    The officers told Moon they had a search warrant for
    his apartment at 99 Ormond Street, but Moon denied that he lived at
    that location.     When Ross told Moon he had just seen him leaving
    the building, Moon admitted he lived there.          Officer Steven
    Smigliani arrived at the scene and placed Moon in the back of his
    cruiser while Ross and Murphy searched Moon's apartment.       Ross
    opened the apartment with the keys he had recovered from Moon's
    pocket.     Moon was escorted into the apartment, where Ross showed
    him a copy of the search warrant and asked if there were any drugs
    in the apartment.    Moon responded that there were some drugs on a
    nightstand in a red box in his downstairs bedroom.
    During the subsequent search of Moon's bedroom, the
    officers found plastic bags containing what appeared to be crack
    cocaine and heroin in a small, red box on the nightstand, and a
    larger bag of heroin within a large bag of rice in the nightstand.
    The officers found another bag containing heroin packed in rice
    under the bed, and in various locations around the room they
    informant, thereby putting him/her at risk.
    -3-
    discovered drug paraphernalia: a scale with drug residue (found
    inside the nightstand), a box of plastic baggies, several cut-off
    baggies, a plate with a razor blade on it, a spoon, and a sifter.
    Under the mattress on the bed, the officers found a Sturm, Ruger &
    Co. Model Service-Six .357-caliber revolver loaded with six rounds
    of ammunition.   The officers also found documents bearing Moon's
    name in the bedroom, including his birth certificate, resume, and
    prescription medication.
    The officers reported the firearm and ammunition to
    Officer Smigliani, who was by then at the police station with Moon.
    Smigliani notified the booking officer to add a firearm and
    ammunition charge to the drug charges already being processed.
    B. Procedural Background
    1. The Indictment
    On June 8, 2011, a federal grand jury returned a multi-
    count indictment charging Moon with possession with intent to
    distribute heroin and cocaine, in violation of 21 U.S.C. § 841(a)
    (Counts One and Two); being a felon2 in possession of a firearm and
    ammunition, in violation of 18 U.S.C. § 922(g)(1) (Count Three);
    and possession of a firearm in furtherance of a drug trafficking
    crime, in violation of 18 U.S.C. § 924(c)(1) (Count Four). The
    government voluntarily dismissed the drug trafficking counts after
    2
    The parties stipulated that Moon had a qualifying felony
    conviction.
    -4-
    learning that the substances had been tested by a state laboratory
    chemist who had used improper techniques.3            The case thus moved
    forward with only the single felon-in-possession charge.
    2. Pre-Trial Motions
    Moon unsuccessfully filed a series of pretrial motions
    seeking      to   suppress   evidence    concerning   the   drugs   and   drug
    paraphernalia found at his apartment and to obtain copies of
    affidavits prepared by BPD officers about the CI and the controlled
    buys.       He requested a Franks hearing to probe the veracity of
    Detective Ross's affidavit and its adequacy to support the search
    warrants executed at his apartment.           See Franks v. Delaware, 
    438 U.S. 154
    , 155-56 (1978). He also renewed a previously filed motion
    for discovery of any exculpatory evidence regarding the CI, as well
    as the exact dates and times of the controlled buys.           The district
    court denied both motions.
    Moon also moved in limine under Federal Rules of Evidence
    404(b) and 403 to exclude testimony regarding the heroin and crack
    cocaine found in his bedroom and his statements to the officers
    regarding the drugs, contending that such information would be
    unfairly prejudicial evidence of uncharged conduct.             In opposing
    the motion, the government stated that it intended to introduce
    evidence showing where the drugs and drug-related items were found
    3
    See Wilkins v. United States, 
    754 F.3d 24
    , 27 (1st Cir.
    2014) (discussing state drug-testing laboratory scandal).
    -5-
    in Moon's apartment because that information went "directly to
    proving the element of knowing possession of a firearm, including
    by way of showing motive."       The government also explained that the
    recovery of cocaine and heroin from the red box on the nightstand
    -- where Moon said drugs could be found -- provided "direct and
    powerful evidence of defendant's dominion and control over the very
    room in which the firearm at issue lay."
    The district court denied the motion, finding the drug
    evidence had special relevance under Rule 404(b) to prove Moon's
    knowledge of and dominion over the firearm.          After conducting its
    Rule 403 balancing, the court held that the probative value of the
    drug evidence was not outweighed by any threat of unfair prejudice.
    The court proposed to give the jury a limiting instruction at the
    time the drug evidence was introduced.
    In early January 2013, as his trial approached, Moon
    moved   for    an   order   requiring   the   government   to   furnish   any
    exculpatory evidence regarding the CI to the district court for in
    camera review.        He argued that the government's intention to
    introduce evidence depicting him as a drug dealer, based on
    "purported controlled buys," "entitled [him] at a minimum, [to] an
    in camera review [of] the requested evidence prior to his trial."
    Moon clarified that he was "not request[ing] disclosure of the
    information but rather an in camera review by the Court to verify
    the Informant's existence and his or her actual participation in
    -6-
    the controlled buys."    He claimed that such a review was necessary
    because "various allegations of misconduct" against Detective Ross
    and Sergeant Detective Murphy, resulting in "'not sustained' or
    'exonerated' dispositions[,] . . . raise substantial questions as
    to potential irregularities" in the BPD investigation.    He further
    argued that he was entitled to the requested discovery under Brady
    v. Maryland, 
    373 U.S. 83
    (1963).
    The district court heard argument on the motion at the
    pretrial conference, during which Moon's counsel emphasized "we're
    not asking for disclosure" and "we're not asking them to disclose
    it to us."    After confirming that the government did not intend to
    call the CI as a witness at trial, the court denied the motion.
    In the week before his trial began, Moon filed a motion
    in limine seeking to bar the government from eliciting expert
    testimony from BPD officers about whether the physical evidence
    discovered at Moon's apartment suggested drug distribution and
    about the frequency with which firearms are found in connection
    with drug distribution.    Moon argued that such testimony would be
    unfairly prejudicial as it would allow the government to introduce
    uncharged conduct and indicate that the government believed he was
    a drug dealer.     He further asserted that such testimony would be
    improper evidence of his "mental state as it relates to the
    essential element of possession: knowledge and intent to exercise
    -7-
    dominion and control," and also would be impermissible expert
    testimony.     The court allowed the testimony.
    Also   shortly   before   trial,   Moon   objected   to   the
    government's use of his prior convictions for impeachment. [App at
    609]    The district court ruled that the government could introduce
    three 2008 convictions and a 2001 robbery conviction by asking Moon
    about "the date of the conviction, the court, and the conviction
    itself."
    C.     Verdict and Appeal
    After a four-day trial, the jury found Moon guilty on the
    firearms charge and the district court imposed a 220-month term of
    imprisonment.       On appeal, he challenges both his conviction and
    sentence, claiming the district court erred when it (1) allowed the
    government to present evidence of uncharged drug possession and
    distribution throughout his trial, (2) allowed the government to
    introduce evidence of the details of Moon's nearly ten-year-old
    conviction for robbery, (3) allowed the arresting officers to offer
    lay opinion testimony that the substances found in Moon's bedroom
    were heroin and crack cocaine, and that drug dealers often possess
    firearms, (4) denied his request for the disclosure of information
    about the CI, or, in the alternative, to conduct an in camera
    review of the documents supporting the search warrant application,
    and (5) when it applied the ACCA in calculating his sentence.

    II.
    A. The Trial Testimony Pertinent to the Appeal
    The jury heard nine witnesses, including Moon, during the
    four days of trial.        Six witnesses testified for the prosecution,
    and   three    for   the   defense.    We    describe   below   the   relevant
    testimony.
    1.   Detectives Murphy and Ross
    Detective Murphy testified that he has executed more than
    500 search warrants, and that he identifies controlled substances
    based on their shape, size, and the way in which they are packaged.
    He stated that drug dealers use the corners of sandwich bags to
    package drugs and the remaining part of the bag is known as a cut
    baggie, several of which were found in Moon's apartment.               Murphy
    stated that he believed the substances found at Moon's apartment to
    be crack cocaine and heroin. He further testified that "a lot of
    drug dealers will use [a firearm] for protection or safety."
    Detective Ross testified that he found a .357 revolver
    under the mattress in the bedroom.           Ross stated that Moon told him
    there were drugs in a red box on the nightstand. During Ross's
    testimony, the government introduced into evidence photographs of
    the drugs and drug paraphernalia seized from Moon's bedroom.             Ross
    testified that these items were consistent with packaging drugs for
    distribution, and that a photograph of the seized substances showed
    cocaine and heroin packaged for sale.
    -9-
    2. Moon and Hendricks
    Moon testified in his own defense that the gun found
    under the mattress was not his, that he had never seen it in the
    apartment, and that he would not allow a gun in his apartment.    He
    acknowledged that he had a history of drug use, which increased
    when his girlfriend, Sherrica Hendricks, left him.        After the
    breakup with Hendricks, who moved out of the apartment in January
    2011, several friends began coming to his apartment and using drugs
    in his bedroom.   Moon testified that his friends sometimes would
    continue to use drugs in the bedroom after he had gone upstairs to
    sleep on the couch in the living room, and one of his friends, "P,"
    sometimes slept in the bedroom.       During the week before he was
    arrested, he "slept more on the couch."     He reported that the day
    before the search warrants were executed, he and his friends had
    pooled their money to buy the heroin and cocaine that was found in
    his bedroom.
    Moon acknowledged ownership of the drug paraphernalia
    found in the bedroom, including a sifter used for heroin, an
    ashtray with a wooly blunt, a plate with a razor used to crush
    crack, and a spoon used to "smash down the crack."       He further
    testified that the drugs found in his bedroom were more than he
    would purchase just for himself, and that he and his friends had
    purchased the larger bags of drugs because they intended to party
    that night.
    -10-
    The government argued that Moon's testimony opened the
    door to questions on cross-examination about his possible drug
    dealing because he "has certainly been intimating . . . that the
    drugs that he had were for personal use, not for distribution."
    Specifically, the government sought to question Moon about the
    transaction officers observed on the street just before executing
    the search warrants, the controlled purchases on which the warrant
    was based, and Moon's arrest six months earlier when Ross and
    Murphy found five grams (a "finger") of heroin in Moon's car. Over
    Moon's objection, the court allowed the questions.       Among the
    questions posed during the cross-examination, the government asked
    Moon if he intended to sell the drugs found in his bedroom on the
    day of the search, and whether he had sold drugs in the few days
    prior to the search.   Moon denied that he ever sold or intended to
    sell drugs.   In addition, Moon denied possessing a finger of
    heroin, claiming that he had only "two or three" grams at the time
    of his earlier arrest.
    Hendricks testified that she never saw a gun in the
    apartment during the two years she lived with Moon at 99 Ormond
    Street, nor did she ever see Moon with a gun.   She testified that
    Moon had occasional visitors to the apartment, though on cross-
    examination she recalled only a single instance in which Moon had
    a visitor in the bedroom.
    -11-
    B. Introduction of Drug-Related Testimony
    Moon argues that the district court abused its discretion
    under   Federal    Rules    of   Evidence     404(b)     and   403   in   allowing
    testimony about the drugs and drug paraphernalia found in his
    bedroom.   He complains that the drug evidence became the focus of
    the trial, and that the government introduced it to convey the
    impermissible message that, because Moon was a drug user, and
    potentially a drug seller, he was the type of person to possess a
    gun.    He explicitly targets the officers' direct testimony and
    appears to challenge as well the government's line of questioning
    in cross-examining him.
    Under Federal Rule of Evidence 404(b), evidence of a
    "crime, wrong, or other act" may not be introduced at trial to
    prove the defendant's propensity to commit the charged offense.
    Fed. R. Evid. 404(b)(1). However, such wrongful-acts evidence "may
    be   admissible    for     another    purpose,    such    as   proving      motive,
    opportunity,      intent,    preparation,      plan,     knowledge,       identity,
    absence of mistake, or lack of accident."              
    Id. at 404(b)(2).
          Even
    if evidence fits within one of the Rule 404(b) categories and is
    thus relevant and admissible, Rule 403 authorizes the trial court
    to exclude the material if its probative value is substantially
    outweighed by a danger of, inter alia, unfair prejudice.                   Fed. R.
    Evid.   403.      Evidence    is     excludable   only    if   it    is    unfairly
    prejudicial, meaning that it has "an undue tendency to suggest
    -12-
    decision on an improper basis."                Fed. R. Evid. 403 advisory
    committee's notes on 1972 proposed rules.
    A district court's ruling that evidence may be admitted
    consistently with both Rules 404(b) and 403 is reviewed for abuse
    of discretion.      United States v. DiRosa, 
    761 F.3d 144
    , 152-54 (1st
    Cir. 2014).        We afford "great deference to a district judge's
    balancing of probative value versus unfair prejudice."                     United
    States v. Breton, 
    740 F.3d 1
    , 14 (1st Cir. 2014).
    We find no abuse of discretion in the district court's
    allowance of the officers' testimony concerning the drugs and
    related paraphernalia found in Moon's bedroom.                That evidence was
    relevant both to show Moon's control over the area where the gun
    was found and to prove his involvement in drug trafficking, which
    "provides a compelling motive for possessing the gun, namely, to
    protect his drugs and drug money."              United States v. Smith, 
    292 F.3d 90
    ,    99    (1st    Cir.   2002);      see   also    United    States     v.
    Torres-Rosario, 
    658 F.3d 110
    , 114 (1st Cir. 2011) (stating that
    "the   government     was   free   to    invite      the   jury   to   infer    that
    Torres–Rosario dealt in drugs" based on the discovery of drugs and
    baggies in his bedroom, "furnishing a motive for him also to
    possess a gun to protect them"); United States v. Weems, 
    322 F.3d 18
    , 25 (1st Cir. 2003) ("As in Smith, the evidence of drug dealing
    at the house was relevant.          It certainly gave Weems a motive to
    have the gun on him.").
    -13-
    Moon asserts that the plethora of personal items found in
    the bedroom, including his resume and prescription medication, made
    control of the bedroom a non-issue and the introduction of the
    highly prejudicial drug evidence therefore unnecessary.                       That
    assertion     would    have    more    force   if   the   drugs    and   related
    paraphernalia were not independently relevant as evidence of drug
    trafficking.       The quantity of drugs found in the room -- two large
    bags of heroin, plus the crack and heroin in the red box on the
    nightstand    --    together    with   equipment    commonly      used   by   drug
    traffickers were enough to support admission of the evidence as
    suggestive of drug dealing.
    As for Rule 403 balancing of relevance and prejudice, the
    court minimized the risk of prejudice by twice giving limiting
    instructions to the jury.             During Ross's testimony, the court
    reminded the jury that Moon was not charged with any drug offense,
    and stated that the testimony was being admitted for a limited
    purpose related to the firearms charge, i.e., to show motive,
    opportunity, intent, preparation, plan, knowledge, identity or
    absence of mistake.      The court also told the jurors they were "not
    permitted to . . . conclude that because he committed a crime
    related to drugs he has a propensity for committing crimes and,
    therefore, committed the crime with which he is charged in this
    case."    The court included a similar instruction in its final
    charge.   Given these precautions, we see no reason to second-guess
    -14-
    the court's judgment that the evidence should be admitted.            See
    United States v. Gonyer, 
    761 F.3d 157
    , 164 (1st Cir. 2014) ("A
    district court's weighing of the positive and negative effects of
    specific evidence demands considerable respect, especially when, as
    in   this   case,   limiting   instructions   were   deftly   and   timely
    deployed." (internal quotation marks omitted)).
    The court's allowance of the government's drug-related
    cross-examination of Moon was likewise within its discretion.
    Moon's testimony implied that the drugs and related paraphernalia
    found in his room were for personal use.4              The government's
    subsequent questioning about drug transactions was designed to
    rebut the personal-use narrative and, in general, to undermine
    Moon's credibility.5     The questions aiming to offset Moon's claim
    of personal use -- and thereby stimulate an inference of drug
    trafficking -- advanced the government's theory that the gun found
    4
    When questioned by his attorney, Moon admitted ownership of
    the drug-related items found in his bedroom, including an ashtray
    containing "pieces of the wooly blunt that I smoked," and two
    plates: "[w]e used one plate when we was cutting up the coke, the
    crack, another plate for the heroin."
    5
    For example, the prosecutor asked Moon a series of questions
    about   the   three   government-orchestrated    controlled   buys.
    Specifically, he was asked, "so you're saying that no one called
    you . . . to request that you sell heroin to them?" Moon denied
    that anyone had. He next was asked if he had driven Sherrica's car
    "to meet with someone to sell them heroin?" Again, Moon denied
    that he had. Finally, the prosecutor asked: "[D]id you . . . any
    time before February 1st of 2011, within a month, did you sell
    anyone heroin in the streets of Boston?" Moon again responded,
    "No."
    -15-
    under Moon's mattress was used "to protect his drugs and drug
    money."      
    Smith, 292 F.3d at 99
    .         As noted, the propriety of
    government reliance on that theory is well              supported by our
    precedent, and the district court thus properly exercised its
    judgment to allow clarifying questions in response to Moon's direct
    testimony. See, e.g., United States v. Tetioukhine, 
    725 F.3d 1
    , 10
    (1st Cir. 2013).
    C. Prior Conviction
    Federal Rule of Evidence 609, inter alia, permits the
    government    to   admit   evidence    of   a   defendant's    prior   felony
    conviction, for impeachment purposes, if the conviction is less
    than   ten   years   old   and   its   probative    value     outweighs   its
    prejudicial effect.    See Fed. R. Evid. 609(a)(1)(B).          As described
    earlier, the district court allowed the government to introduce
    three 2008 convictions and a 2001 robbery conviction. Challenging
    on appeal only the government's use of the nearly ten-year-old
    robbery conviction, Moon claims that the court erred in balancing
    prejudice and probative value.
    On the second day of trial, Moon's attorney renewed his
    pretrial objection to the use of the robbery conviction on the
    ground that it was "very close in nature to a weapons" charge and,
    accordingly, the government should be prohibited from raising it.
    In response, the government said that it would ask Moon "are you
    the same person who was previously convicted of robbery in Suffolk
    -16-
    Superior Court on March 29, 2001?"      In light of that limited
    inquiry, the court ruled that the probative value of the prior
    conviction outweighed the prejudicial effect of its introduction,
    and the question was therefore permissible.
    Knowing that he would be asked about the conviction on
    cross-examination, Moon preemptively testified on direct that he
    had been convicted of unarmed robbery in 2001.     When his lawyer
    asked him to explain the conviction, Moon provided his account of
    the events:
    This guy came in our neighborhood, he was
    asking people to get him some drugs, can they
    get him some drugs. He asked me; I told him I
    could get it for him. So what I did was I went
    and got a napkin, I didn't have any drugs, but
    I wanted the money. I got a napkin, so I told
    him the drugs were in the napkin, handed him
    the napkin, got the money, and walked away. I
    walked away, and I was surrounded by the
    police. He turned out to be an undercover cop,
    and I was convicted of robbery.
    Following Moon's testimony, but before beginning its
    cross-examination, the government argued that Moon had opened the
    door to questions about the circumstances surrounding the robbery
    conviction.   The district court agreed,6 but said it would be
    "listening carefully" to the prosecutor's questions to determine if
    they were unduly prejudicial under Rule 403.
    6
    The court noted that "the government wouldn't have been able
    to get into this issue had it not been for [Moon's] testimony," in
    which he "proffered his version of facts for the underlying
    conviction and was selective about what facts he addressed on
    direct."
    -17-
    During its cross-examination, the government asked Moon
    about   the    facts    underlying    the    robbery    conviction,      including
    whether he had gotten into a car with the officer, snatched money
    from the officer's hand, told the officer, "I wasted enough time
    with you, get out of here before you get hurt," and negotiated the
    price   of    the    heroin.    The    district     court      sustained     Moon's
    objection, however, to questions asking Moon if he had told the
    officer he had a pistol with him during the robbery, ruling that
    this was too "close to the line" given that Moon was facing a gun
    charge in this case.
    Although Moon invokes Rule 609 in asserting that the
    evidence surrounding his 2001 robbery conviction was improperly
    admitted, that rule is beside the point where, as here, the
    challenged evidence was offered to contradict specific testimony.
    A   party      can     "open   the    door     to      evidence      about   prior
    convictions . . . regardless of whether the conviction meets Rule
    609's   requirements."

      (internal
    quotation marks omitted).            "A party may introduce evidence to
    impeach a witness's specific testimony by contradiction," and
    "[t]his principle applies to the admission of prior convictions."
    
    Id. at 8-9.
    By providing his own depiction of the robbery, Moon
    opened the door to the government's cross-examination about the
    events leading to the conviction. Moon's account had the potential
    -18-
    to   "create[]     a    false   impression     that   made   the    [underlying]
    circumstances . . . relevant," United States v. Landry, 
    631 F.3d 597
    , 605 (1st Cir. 2011), and, hence, the court did not abuse its
    discretion by allowing the government to question him about facts
    inconsistent with his version of the events.               See 
    Tetioukhine, 725 F.3d at 10
    ("Tetioukhine's repeated attempt[s] to minimize the
    conduct for which he was convicted were more than sufficient to
    open the door to further cross-examination on this subject."

    misleading testimony).
    D. Arresting Officer Testimony
    Both pretrial and at trial, Moon sought to prevent
    Detective Ross and Sergeant Detective Murphy from offering opinion
    testimony that drug dealers typically keep firearms to protect
    themselves and their drugs, and that the drugs seized in Moon's
    apartment were heroin and cocaine.7             The district court admitted
    this testimony as lay opinion evidence, citing our decision in
    7
    We note that Moon's objection to the officers' testimony
    about the drugs found in his bedroom is largely undermined by his
    own admission that the substances were heroin and cocaine. When
    asked on cross-examination to identify the substances in a
    photograph taken by the police, Moon said, "that's the coke we had
    and the methadone pills that I was going to take." In explaining
    another photograph, he stated: "That's heroin . . . . I think
    it's, like, three grams, three and a half grams."

    the admission of lay or expert testimony for abuse of discretion.
    United States v. Diaz-Arias, 
    717 F.3d 1
    , 11 (1st Cir. 2013);
    
    Valdivia, 680 F.3d at 50
    .
    The district court correctly concluded that admission of
    the   offered    testimony   is   consistent   with   our   precedent   as
    articulated in Valdivia.9     Federal Rule of Evidence 701 provides:
    8
    The district court stated:
    Finally, there was an objection to allowing the
    detective, I believe it was Detective Ross, to testify
    about whether or not drug distributors or drug dealers
    often possess firearms. And there was an objection under
    [Rule] 702, that there wasn't a proper foundation laid
    for that expert testimony. I would say that I don't think
    the admission of that testimony was improper. The 1st
    Circuit had addressed this issue in [Valdivia]. I don't
    believe that that case requires the same showing for the
    testimony that was proffered that is required for experts
    squarely offered under [Rule] 702. And even if [Rule] 702
    did apply, I think that testimony was properly admitted.
    9
    Speaking only for myself, I adhere to the view set forth in
    my concurrence in Valdivia that the admission of certain types of
    opinion testimony of police officers as lay opinion is contrary to
    the requirements of Rules 701 and 702:
    [T]he explicit language of Rule 702 sets forth a bright
    line rule.    If a witness has acquired "specialized
    knowledge" on the basis of "knowledge, skill, experience,
    training or education," and presents that knowledge to a
    jury "in the form of an opinion or otherwise," that
    witness is testifying as an expert witness, Fed. R. Evid.
    702, who is subject to the disclosure requirements for
    expert testimony.
    
    Valdivia, 680 F.3d at 60
    (Lipez, J., concurring). Our court's
    position that police testimony under Rule 702 is lay opinion
    testimony under Rule 701 "has created in some of our precedents an
    unwarranted police exception from the requirements applicable to
    -20-
    If a witness is not testifying as an expert,
    testimony in the form of an opinion is limited
    to one that is: (a) rationally based on the
    witness's perception; (b) helpful to clearly
    understanding the witness's testimony or to
    determining a fact in issue; and (c) not based
    on scientific, technical, or other specialized
    knowledge within the scope of Rule 702.
    In   Valdivia,   we    upheld,   as   lay    opinion   under    Rule    701,   the
    admission of a law enforcement agent's testimony describing the use
    of   cell   phones      by   drug     traffickers,     citing     the    agent's
    "particularized knowledge" derived from his experience in past drug
    investigations.       
    See 680 F.3d at 50-51
    (quoting Fed. R. Evid. 701,
    advisory committee's note to 2000 amendment).
    Here, the officers also had the requisite knowledge of
    drug-dealing practices. See 
    id. at 50.
    Ross, a 27-year veteran of
    the BPD, testified that he had experience in identifying controlled
    substances, particularly from occasions when he purchased drugs on
    the streets of Boston.           Murphy, a 33-year veteran of the BPD,
    testified that he had made a minimum of 5,000 drug arrests during
    the course of his career, and that "a lot of drug dealers will use
    [a firearm] for protection or safety."            The officers' testimony,
    based on their extensive experience, that the substances appeared
    to be heroin and crack cocaine, and that drug dealers often possess
    firearms, was, according to our precedent, thus properly admitted
    expert testimony."

    Our law on this point is at odds
    with virtually every other circuit.

    E. The Existence and Identity of the Informant
    Moon argues that the district court violated his right of
    confrontation and his due process rights when it denied his request
    pretrial, during trial, and in his new trial motion, for disclosure
    of the identity of the CI and the details of the CI's activity, or,
    in the alternative, a review by the court in camera of the
    10
    The district court observed that even if the officer
    testimony was not lay opinion testimony, it could have been
    admitted as expert testimony. That statement would be correct so
    long as the pretrial requirements for the admission of expert
    testimony were met by the government.       If the government had
    attempted to introduce this testimony as expert testimony, it would
    have had to disclose the identity of the officers as well as,
    "among other things, the subject matter on which the witness is
    expected to testify and a summary of the facts and opinions to
    which the witness is expected to testify." 
    Valdivia, 680 F.3d at 60
    n.21 (Lipez, J., concurring) (citing Fed. R. Civ. P. 26(2) and
    Fed. R. Crim. P. 16(a)(1)(G), (b)(1)(C)).

    documents supporting the application for the search warrants.
    Relatedly, he argues that the district court erred in refusing to
    convene a Franks hearing to probe the veracity of the search
    warrant affidavit.        Moon contends that he was unfairly prejudiced
    by his inability to review the information allegedly supplied by
    the CI and argues that, at a minimum, the court should have
    examined   the    supporting        materials      to    determine   whether    the
    informant in fact existed and engaged in controlled buys with him.
    1.    Pretrial Requests
    We note first that Moon waived his objection to the
    district court's refusal to order pretrial disclosure of the
    informant's identity.         In his renewed motion for discovery, Moon
    stated that he did "not seek the identity of the informant, but
    only the type of information – promises, rewards, and inducements,
    convictions,      pending      cases       –     that    would   tend     to    show
    unreliability."         Similarly, in his motion for in camera review,
    Moon   stated    that    he   was   not    seeking      disclosure   of   the   CI's
    identity, but urged the court to verify the informant's existence
    and the facts of the controlled buys. These affirmative statements
    constitute an "intentional relinquishment" of any claim of error in
    the district court's pretrial denial of his request for disclosure
    of the CI's identity.         United States v. Millan-Isaac, 
    749 F.3d 57
    ,
    63 (1st Cir. 2014).
    -23-
    Moon has consistently argued, however, that the facts
    alleged by the government detailing the controlled buys should be
    examined and evaluated, demanding that such inquiry be performed in
    a hearing pursuant to Franks and through in camera review of the
    materials supporting the warrant affidavit.                   On appeal, he argues
    that    the    district    court    erred       in   rebuffing     both     of   these
    procedures.       He contends that the court should have demanded
    reliable proof that the CI existed and the controlled buys in fact
    occurred.
    Under Franks, a defendant may overcome the presumption of
    validity that surrounds an affidavit in support of a search warrant
    and obtain an evidentiary hearing if he "makes a substantial
    preliminary      showing    that     a    false      statement      knowingly     and
    intentionally, or with reckless disregard for the truth, was
    included by the affiant in the warrant affidavit, and if the
    allegedly false statement is necessary to the finding of probable
    cause."       
    Franks, 438 U.S. at 155-56
    ; see also United States v.
    McLellan, 
    792 F.3d 200
    , 208-09 (1st Cir. 2015).                      We review for
    clear   error    a   district      court's      denial   of    a   Franks    hearing.
    
    McLellan, 792 F.3d at 208
    .
    Moon attempted to discredit the affidavit's report of the
    controlled buys by establishing that he was not in Boston on the
    one date reported with some specificity in the application, i.e.,
    within "the last seventy-two hours."                 In his own affidavit, Moon
    -24-
    stated that he did not sell heroin to anyone in the Boston area
    during the three days preceding and including February 4, 2011, the
    date on which the search warrants issued, and that he had spent
    "most of my time" in Worcester, Massachusetts, during the first
    week of February 2011. He argues that his affidavit, together with
    records from the American Automobile Association ("AAA") showing a
    request for a tow of the green Mercedes identified in the warrant
    application, establish that "he was not in town during at least one
    of the incidents contained in the search warrant."
    We find no clear error in the district court's judgment
    that Moon's proffered evidence did not amount to a "substantial"
    showing of falsity.        The AAA records show only that a call was
    placed from Worcester on February 4, 2011 -- the date on which the
    search warrants were sought -- for a tow of the green Mercedes.
    Those records do not establish that Moon was out of town for the
    full 72 hours (or any substantial part of that period) before
    officers filed the warrant application. Likewise, Moon's assertion
    in his affidavit that he was spending "most" of his time in
    Worcester   during   the    relevant   period   does   not   undermine   the
    allegation in the affidavit that one of the controlled buys of
    heroin occurred in Boston within 72 hours of the February 4
    application.    Worcester and Boston are approximately 45 miles
    -25-
    apart,11 and Moon easily could have been in both cities on the same
    day.
    The factual gap in Moon's attempt to show the affidavit's
    inaccuracy -- and thus its knowing or reckless falsity -- cannot be
    filled by his own denial that he sold heroin in Boston within the
    relevant period.           That disclaimer constitutes no more than a
    conclusory and unsupported allegation that falls well short of the
    "substantial preliminary showing" necessary to justify a Franks
    hearing.      See United States v. Southard, 
    700 F.2d 1
    , 10 (1st Cir.
    1983) (upholding rejection of Franks hearing where district court
    found        appellants'         flat    denials     of    gambling-related
    conversations insufficient to meet the "substantial preliminary
    showing" requirement).
    Moon's challenge to the district court's denial of an in
    camera       examination    of    the   evidence   supporting   the   warrant
    application fails for similar reasons.             In a case such as this,
    where the defendant questions the truthfulness of an affidavit but
    has not made the "substantial preliminary showing" required by
    Franks, the district court may hold an in camera proceeding to
    probe the veracity of the officer and, if necessary, the informant.
    11
    We take judicial notice of this distance. See Fed. R. Evid.
    201(b) (allowing a court to take judicial notice of a fact "not
    subject to reasonable dispute because it . . . can be accurately
    and readily determined from sources whose accuracy cannot
    reasonably be questioned"); see also United States v. Fernandez,
    
    722 F.3d 1
    , 6 n.1 (1st Cir. 2013).
    -26-
    See United States v. Manning, 
    79 F.3d 212
    , 220 (1st Cir. 1996).
    The judgment of whether to do so, however, is left to the court's
    discretion.        
    Id. As described
    above, Moon has failed to make any
    showing that in camera review would reveal falsity or any evidence
    of value to his defense.           Hence, we find no abuse of discretion in
    the court's rejection of in camera review.                See 
    id. at 221
    ("Given
    the    tenuous      basis   for    [the    defendant's]         challenge     to    [the
    detective/affiant's] veracity, the district court's denial of
    [defendant's] request for an in camera review was well within its
    discretion.").
    2.    Mid-trial and Post-trial Requests
    Moon revisited the CI identity issue during the trial and
    in    his    post-verdict    motion       for    new   trial,    arguing     that   the
    government's        cross-examination           concerning      his     alleged     drug
    trafficking entitled him to disclosure of the informant's identity
    and related details.         When the government announced its planned
    line of questioning about the controlled buys, 
    see supra
    Section
    II.B,       Moon   noted    that     those       transactions         were   disputed.
    Referencing Federal Rule of Evidence 404(b)(2),12 he stated that,
    12
    Pursuant to Federal Rule of Evidence 404(b), evidence of a
    defendant's "crime, wrong, or other act . . . may be admissible for
    another purpose, such as proving motive, opportunity, intent,
    preparation, plan, knowledge, identity, absence of mistake, or lack
    of accident. On request by a defendant in a criminal case, the
    prosecutor must: (A) provide reasonable notice of the general
    nature of any such evidence that the prosecutor intends to offer at
    trial; and (B) do so before trial -- or during trial if the court,
    for good cause, excuses lack of pretrial notice." Fed. R. Evid.
    -27-
    "if    the   government   is    allowed   to   go    into   any   alleged   prior
    transaction, I'm entitled to notice and disclosure of those so I
    can prepare to rebut them."          The court refused to order disclosure
    of the details of the controlled buys and, as described above,
    allowed the questioning.
    In a motion for new trial after the guilty verdict, Moon
    renewed his objection to the court's failure to order disclosure of
    the CI's identity or other information about the controlled buys,
    arguing that he was unfairly denied the ability "to negate the
    insinuations made by the government on cross-examination that Mr.
    Moon was involved in multiple drug transactions prior to his
    arrest." In denying the motion, the district court stated that the
    government was not required to disclose the details concerning the
    CI because it did not rely at trial on information provided by the
    informant.      On appeal, Moon reiterates his contention that his
    defense was compromised by the court's refusal to order disclosure
    of the CI's identity and details of the alleged buys.
    The government has a qualified privilege to withhold the
    identity of people who provide law enforcement officers information
    about criminal acts.        See Roviaro v. United States, 
    353 U.S. 53
    ,
    59-60 (1957); United States v. Mills, 
    710 F.3d 5
    , 13 (1st Cir.
    2013). When a defendant requests disclosure of a confidential
    informant's     identity,      the   court    must   determine    whether    that
    404.
    -28-
    information is "relevant and helpful to the defense" or "essential
    to a fair determination of a ca[se]."            
    Roviaro, 353 U.S. at 60-61
    .
    The   court    also   must     balance     the       individual's     "right     to
    prepare . . . his defense against the public interest in acquiring
    needed information and the informant's stake in confidentiality."
    
    Mills, 710 F.3d at 14
    (quoting United States v. Perez, 
    299 F.3d 1
    ,
    4 (1st Cir. 2002)).     The burden is on the defendant to show that
    "disclosure is essential for an adequate defense," 
    id., and the
    inquiry   is   case-specific:     "Whether       a    proper   balance    renders
    nondisclosure erroneous must . . . tak[e] into consideration the
    crime charged, the possible defenses, the possible significance of
    the informer's testimony, and other relevant factors," 
    Roviaro, 353 U.S. at 62
    .
    The district court's judgment not to order disclosure of
    a confidential informant is reviewed for abuse of discretion.
    United States v. Robinson, 
    144 F.3d 104
    , 106 (1st Cir. 1998).                    We
    are satisfied that no such abuse occurred in this case.                       Moon's
    contention is that, without the CI's identity and some detail about
    the   transactions    (e.g.,    dates    and     locations),     he   could     not
    challenge the government's depiction of him as a drug dealer.                   The
    government, however, offered no testimony at trial about the
    controlled buys, either in its case-in-chief or to rebut Moon's
    denials   on    cross-examination        of    his     involvement       in    drug
    trafficking.    The government referred to the transactions only by
    -29-
    asking Moon, during cross-examination, about his conduct.                     
    See supra
    n.5.
    Moon does not explain how he would have used the CI
    information if the court had ordered it disclosed at that point in
    the trial.     Cf. 
    Mills, 710 F.3d at 14
    ("[A] defendant must spell
    out how an informer's testimony would help whatever defense theory
    he pins his hopes on."). In addition, although Moon's alleged drug
    trafficking was circumstantially useful to the government, it was
    not the crime before the jury.                See   
    id. at 14
    (noting the
    importance of disclosure if "the informant is the only person other
    than   the   defendant    who   has   firsthand     knowledge   of    the   acts
    underlying the crime charged" or "the only one able to amplify or
    contradict the testimony of a government witness").                The district
    court did not abuse its discretion in concluding that Moon had not
    met his heavy burden to show that disclosure was "essential for an
    adequate defense."       
    Id. at 14.
    F.   Sentencing Under Armed Career Criminal Act
    The Probation Office determined that Moon was subject to
    sentencing    as   an   armed   career   criminal     based   on    five    prior
    convictions for violent felonies.            Moon's total offense level of
    34, when combined with his Criminal History Category of VI,
    produced a Guidelines sentencing range of 262 to 327 months.                  The
    court sentenced Moon to 220 months' imprisonment and two years of
    supervised release.

    Moon argues that the district court's application of the
    ACCA    violated    his       right   to   a   jury     trial   because   his   prior
    qualifying convictions were not charged in the indictment or proven
    to a jury beyond a reasonable doubt.                       He contends that his
    predicate convictions are facts that increase the mandatory minimum
    sentence, and hence constitute "elements" that must have been
    submitted to the jury.            See Alleyne v. United States, 
    133 S. Ct. 2151
    (2013).       Moon's contention is without merit.              Under now well
    established law, the fact of a prior conviction need not be proven
    to a jury beyond a reasonable doubt for sentencing purposes, even
    when    it   exposes      a     defendant      to   a    higher   sentence.       See
    Almendarez-Torres v. United States, 
    523 U.S. 224
    , 239 (1998);
    United States v. Almenas, 
    553 F.3d 27
    , 31 n.3 (1st Cir. 2009).
    Accordingly, the district court did not deny Moon his right to a
    jury trial when it applied the ACCA enhancement.13

    On July 7, 2015, Moon submitted a Motion for Leave to File
    Supplemental Briefing to address the impact of Johnson v. United
    States, 
    135 S. Ct. 2551
    (2015), which struck down the residual
    clause of the ACCA as unconstitutionally vague. In his motion,
    Moon argued that but for the residual clause of the ACCA, he would
    not have qualified as an armed career criminal.      We denied the
    motion. Moon has the requisite number of predicate convictions
    that qualify as violent felonies under the "force or elements
    clause" of the ACCA, and the residual clause is thus not implicated
    in this case.

    III.
    Having considered each of Moon's claims of error, and
    finding no basis for disturbing either his conviction or sentence,
    we affirm the judgment of the district court.
    So ordered.
