    The Hon. David H. Souter, Associate Justice (Ret.) of the
    Supreme Court of the United States, sitting by designation.
    LIPEZ, Circuit Judge.            Appellant Marc Jadlowe raises
    multiple issues of substance in challenging his conviction on drug
    conspiracy     charges.        Most   significantly,       he   argues    that   the
    district court committed structural error by instructing the jurors
    that they could discuss the case among themselves during the trial,
    before     formal    deliberations     commenced.          We   agree     that   the
    instruction was erroneous. We conclude, however, that a showing of
    prejudice is necessary to justify a new trial based on premature
    jury discussions.           As the record here shows beyond a reasonable
    doubt that the flawed instruction did not compromise the jury's
    deliberative process, Jadlowe is not entitled to a new trial on
    that basis.      We also find no reversible error in the suppression
    and evidentiary rulings that Jadlowe disputes. We therefore affirm
    the judgment of conviction.
    I.
    In November 2005, a federal grand jury charged Jadlowe
    and   fourteen      other    individuals     in   an   eleven-count      indictment
    alleging various drug-related crimes.1                 Jadlowe was named in two
    counts, one alleging conspiracy to possess and distribute cocaine,
    in violation of 
    21 U.S.C. § 846
    , and the other alleging possession
    and distribution of cocaine on November 4, 2005, in violation of 
    21 U.S.C. § 841
    (a)(1).            We set forth here the background of the
    1

    -2-
    conspiracy, as depicted by the government at a suppression hearing
    and at trial.2
    In      late      September      2005,      the   Drug    Enforcement
    Administration ("DEA") initiated a wiretap on the phone of Brandin
    Gonsalves,          one   of     Jadlowe's     co-defendants,     as    part    of   an
    investigation into drug trafficking activities in and around New
    Bedford, Massachusetts.               Within the first week of the wiretap, the
    DEA intercepted a call between Gonsalves and another defendant,
    John       Ferreira,      Jr.,   in   which    the   men   discussed    using   "Uncle
    Mar[c]'s" garage to store a suspected shipment of cocaine.3                          Law
    enforcement agents concluded that "Uncle Marc" was Jadlowe based
    on, inter alia, pen register data obtained from Gonsalves's phone
    showing that Gonsalves frequently exchanged calls with a phone
    number the agents linked to Jadlowe.4
    2
    Jadlowe does not dispute the sequence of events described by
    the government, but he claims that the government did not prove his
    knowing involvement in a cocaine conspiracy.         He argues in
    particular that the admissible evidence failed to show that he was
    one of the participants in a series of wiretapped phone
    conversations in which the government identified him as a speaker
    or that he was the individual seen on a videotape made by officers
    doing surveillance at his home.
    3
    On October 21, 2005, the government obtained court approval
    for a second wiretap of Gonsalves's phone and an initial wiretap of
    Ferreira's phone.

    A "pen register" is a device used, inter alia, to record the
    dialing and other information transmitted by a targeted phone. 
    18 U.S.C. § 3127
    (3); see also United States v. Santana, 
    175 F.3d 57
    ,
    61 n.2 (1st Cir. 1999). DEA Task Force Agent Andrew Simmons
    testified that a "pen order" authorized law enforcement officers
    "to track who was calling the phone number, what numbers were being
    -3-
    On October 5, 2005, DEA agents intercepted a call between
    Gonsalves   and    Ferreira    at    10:24      p.m.,   and   another   call   from
    Gonsalves to Jadlowe a minute later, in which the men discussed how
    much Jadlowe would be paid for the use of his garage to temporarily
    store ten to twenty kilograms of cocaine.               On October 8, Gonsalves
    and Jadlowe discussed putting a generator in Jadlowe's house and
    running an extension cord, apparently to provide light for the
    unloading of the cocaine in the garage.5                Although Gonsalves told
    Jadlowe the drugs were expected to arrive "in a couple of days,"
    a call between Gonsalves and Ferreira on October 21 indicated that
    the delivery had been delayed because the supplier had run into
    problems with law enforcement authorities.6
    On    November    3,    the   DEA    intercepted    a   call   between
    Ferreira and an unidentified male who reported that "[m]y plane got
    delayed but, yeah my girl be here early in the morning," prompting
    agents to set up surveillance for the next day at Jadlowe's home at
    called, the duration of the call, the time of day of the call, and
    we would get that real time."
    5
    Agent Simmons testified that the gas and electricity were
    shut off at Jadlowe's home address during that time period.
    6
    In the call, Ferreira told Gonsalves that he had spoken with
    "Fofado" and that "Rudolfo got bagged up by the feds . . .
    [c]rossin' you know." Agent Simmons testified that the government
    was unable to identify Rudolfo or to connect this conversation with
    a specific drug seizure.

    30 Arch Street in Dartmouth, Massachusetts.7               Early on November 4,
    DEA    Special      Agent    Michael   Barbuti     and   other   law    enforcement
    officers began physical surveillance near Arch Street while Agent
    Simmons and his team monitored the Gonsalves and Ferriera wiretaps
    from another location.              At about 11 a.m., DEA Special Agent
    Jennifer Fallon began surveillance of 30 Arch Street from an
    unmarked police truck that was parked on a street parallel to Arch
    Street, monitoring the scene through a video camera.8
    Shortly before 2 p.m., the multi-faceted surveillance
    bore fruit.        Fallon saw someone enter the garage at 30 Arch Street,
    at which point she turned on the camera and began videotaping.                  She
    then       saw   the   man   move   items   from   the    garage   to    the   yard.
    Meanwhile, the wiretap was capturing calls between Gonsalves and
    Jadlowe revealing that Jadlowe was clearing out his garage to make
    7
    The buildings at 30 Arch Street, which were owned by
    Jadlowe's family, consisted at that time of an unoccupied house,
    still under construction, that was attached to the garage at the
    front of the property and a separate residence behind that
    structure (identified as 30R Arch Street).     Jadlowe's driver's
    license and vehicle registration both listed 30 Arch Street as his
    address.
    8
    Fallon was the only agent with a direct view of 30 Arch
    Street, but she testified that she "was just looking at a screen
    inside the truck," not out any windows.     Other officers would
    occasionally drive by the house, but Barbuti explained at the
    suppression hearing that they could not park within sight of the
    house because "[i]t's a very residential area with no sidewalks,
    and vehicles that would be parked there would be easily
    recognized."

    room for a truck.9    About an hour later, Jadlowe called Ferreira
    and told him the garage was "all set" – the doors were unlocked,
    and the back window was open to let in light.   As agents watched,
    Jadlowe then left the garage and drove away.
    At about 3:45 p.m., agents saw a white truck enter
    Jadlowe's garage.    At 3:53 p.m., Ferriera called Jadlowe and said
    that "they" were over at his house, in the garage, "right now" and
    had been there for ten minutes, but that there were "no lights over
    there."   Jadlowe instructed Ferreira to tell them to remove paper
    that was covering the door as a way to allow in more light.     At
    approximately 4:16 p.m., Ferreira reported to Jadlowe that "them
    cats are putting the truck back together.   They're out of there."
    At about 4:30 p.m., agents saw the truck leave the garage and drive
    away and, a minute later, Jadlowe called Ferreira to report that he
    had seen the truck leaving his street.   The two men agreed to meet
    at 30 Arch Street.    Jadlowe was seen on the video arriving at his
    residence a few minutes later, and in a series of three recorded
    conversations at about 4:40 p.m., Ferreira asked Jadlowe if he
    could "see them things there . . . [r]ight above the window behind
    the insulation."10   The men were still on the phone as Ferreira
    9
    In the first call, at 1:56 p.m., Jadlowe reported that he
    was "[t]aking care of the garage."      At 2:40 p.m., he told
    Gonsalves: "You should be able to fit the truck in here no
    problems."
    10
    Simmons testified that much of the communication between the
    conspirators in this case was conducted by using phones as "Direct

    arrived at 30 Arch Street, at which point he told Jadlowe that he
    did not want "them things just bring the phone."     Ferreira and
    Jadlowe were seen driving off together at about 4:50 p.m.
    Meanwhile, after being alerted by phone, Massachusetts
    State Trooper Stephen Fortin had stopped the white truck for a
    license plate violation a short distance from 30 Arch Street.
    Officers observed Ferreira drive past the truck and patrol car,
    and Simmons testified that contemporaneous phone calls Ferreira
    made to Gonsalves and a man named "Snack" revealed that the men
    were "in somewhat of a panic" about the truck's detention and the
    "need[] to move the stuff" from Jadlowe's garage.
    At approximately 5:30 p.m., Agent Fallon saw a car pull
    into the driveway of 30 Arch Street and, with the car's headlights
    shining into the garage, an individual entered the building. Agent
    Barbuti and his team arrived soon thereafter, and he and another
    officer encountered Jadlowe coming out a door from the garage.
    Jadlowe was arrested, pat-frisked and handcuffed, and a cell phone
    was taken from him.11   Agents then entered the garage, where they
    saw in plain view ten brick-shaped packages that turned out to be
    kilogram amounts of cocaine stacked atop a pile of drywall toward
    Connect" devices, a mode in which they functioned like walkie-
    talkies. When the phones were used that way, a new "session" was
    recorded each time a change in speaker occurred.
    11
    There is a disagreement between the parties about whether
    the record shows that the phone was seized in the frisk. See infra
    Section IIB.

    the rear of the garage.      Several agents remained in the garage
    overnight while Agent Simmons obtained a search warrant for the
    property.   At about 11 a.m. the next day, November 5, 2005, agents
    executed a warrant for Jadlowe's garage and the two houses at 30
    and 30R Arch Street.    They seized the ten packages of cocaine from
    the garage and other items, including phone records, from the
    houses.
    Following his indictment on the two drug trafficking
    charges, Jadlowe filed a motion to suppress the evidence seized on
    November 4 and 5. After an evidentiary hearing, the district court
    denied suppression of the cocaine and the cell phone,12 but granted
    his motion to suppress the evidence seized from the two houses.13
    A five-day jury trial concluded on July 7, 2008, with findings of
    guilt on both counts.   Jadlowe was sentenced to 120-month terms of
    imprisonment on each count, to run concurrently, followed by five
    years of supervised release.
    On appeal, Jadlowe renews his argument that the cocaine
    and cell phone should have been suppressed because they were
    products of the officers' unlawful entry and overnight stay in his
    garage, and he argues that the court also should have suppressed
    12
    The court found that the phone was seized from Jadlowe's
    person at the time of his arrest.
    13
    The government had in fact conceded that the items found in
    the houses must be suppressed because the affidavit filed in
    support of the search warrant application established probable
    cause to search only the garage.
    -8-
    phone records that he claims were linked to documents found during
    the unlawful search of his home.            He also raises a host of
    evidentiary arguments: (1) the court should have excluded an
    exhibit containing a list of incoming and outgoing wiretapped calls
    because that list consisted of inadmissible hearsay; (2) the court
    erred in allowing Agent Fallon to give lay opinion testimony
    identifying Jadlowe in the November 4 videotape; (3) the court erred
    in allowing Agent Simmons to identify Jadlowe's voice in wiretapped
    phone conversations; and (4) the court erred in allowing the jury
    to   view   transcripts   of   wiretapped   phone   conversations   that
    identified Jadlowe as one of the speakers.            Finally, Jadlowe
    asserts that a new trial is required because the district court
    virtually invited the jury to engage in premature deliberations
    when it instructed the jurors that, as the trial progressed, they
    could talk about "interesting things that happened during the
    course of the trial, . . . interesting things witnesses say,
    significant pieces of evidence."
    We begin our discussion with the court's suppression
    rulings.
    II.
    Jadlowe challenges the district court's denial of his
    pretrial motion to suppress the cocaine and cell phone found at 30
    Arch Street, as well as the court's ruling at trial allowing the
    government to introduce records that he claims were the tainted
    -9-
    "fruit" of the illegal search of his houses.               In evaluating the
    denial of a suppression motion, we review the district court's
    findings of fact for clear error and its legal conclusions de novo.
    United States v. Larios, 
    593 F.3d 82
    , 92 (1st Cir. 2010).               As the
    issues differ with respect to each of the three challenged items of
    evidence, we address them separately.
    A. The Cocaine
    The    government   concedes       on   appeal    that     the   law
    enforcement officers initially saw the ten bricks of cocaine during
    an unlawful entry into Jadlowe's garage. The officers did not have
    a search warrant, and the government accepts the district court's
    implicit finding that the entry was not justified by exigent
    circumstances.    Noting the distinction "between the securing of a
    premises   from   its   perimeter,    which   does   not    require    exigent
    circumstances, and the impounding of a premises by occupying it
    from the inside, which does," see United States v. Dessesaure, 
    429 F.3d 359
    , 370 (1st Cir. 2005),14 the court pointed out that 30 Arch
    Street was under "close physical surveillance" on November 4 and
    that the only realistic risk that the cocaine would be moved or
    14
    We noted in Dessesaure that some police officers "may have
    mistakenly believed that they were free, absent a search warrant or
    exigent circumstances, to enter a dwelling in order to 'freeze' the
    scene." 
    429 F.3d at 370
    .
    -10-
    that any other evidence would be destroyed was eliminated by
    Jadlowe's arrest.15
    The court went on to conclude, however, that the cocaine
    was nonetheless admissible at trial under the principles set out in
    Segura v. United States, 
    468 U.S. 796
     (1984), and its progeny.                     In
    Segura, the Court held that an illegal entry to secure a premises
    did not preclude admission of evidence found during a later search
    of the same location pursuant to a warrant drawn from sources
    "wholly    unconnected      with    the      [illegal]     entry."    
    Id. at 814
    .
    Although the evidence at issue in Segura had been discovered for
    the first time during the second, untainted search, the Court in
    Murray     v.    United   States,      
    487 U.S. 533
        (1988),   extended    the
    "independent source" doctrine to "evidence that had been observed
    in plain view at the time of a prior illegal entry," 
    id. at 535
    .
    The   Court      stated   that   the    question     in    such   circumstances   is
    "whether the search pursuant to warrant was in fact a genuinely
    independent source of the information and tangible evidence at
    issue."     
    Id. at 542
    .      That would not be so, the Court explained,
    "if the agents' decision to seek the warrant was prompted by what
    they had seen during the initial entry, or if information obtained
    15
    In light of those circumstances, the court also rejected
    applicability of the "'protective sweep' rule" of Maryland v. Buie,
    
    494 U.S. 325
     (1990), which allows officers to conduct a warrantless
    "sweep" of a premises following an arrest based on a reasonable
    belief "that the area to be swept harbors an individual posing a
    danger to those on the arrest scene." 
    Id. at 337
    .
    -11-
    during that entry was presented to the Magistrate and affected his
    decision to issue the warrant."            
    Id.
    In Dessesaure, 
    429 F.3d at 367-69
    , we adopted a two-part
    inquiry to implement Murray's holding.                    In determining whether
    evidence discovered in a lawful search pursuant to a warrant may be
    admissible in the aftermath of an unlawful entry, we consider: (1)
    whether    the     search      warrant    affidavit        contained    sufficient
    information to support probable cause without any information
    gleaned from the unlawful search; and (2) whether the decision to
    seek the warrant was in fact "'independent of the illegal entry,'"
    i.e., "'whether it would have been sought even if what actually
    happened had not occurred.'"            
    Id.
     (quoting Murray, 
    487 U.S. at
    542
    n.3); see also United States v. Siciliano, 
    578 F.3d 61
    , 68 (1st
    Cir. 2009) (noting that, "under the independent source doctrine,
    'evidence acquired by an untainted search which is identical to
    . . . evidence unlawfully acquired' is admissible" (quoting Murray,
    
    487 U.S. at 538
    )).
    Jadlowe concedes that the officers had probable cause to
    search    the    garage   even   before    they     saw    the   cocaine,   and    he
    therefore contests only prong two, i.e., the district court's
    conclusion      that   the    agents'    decision    to     seek   a   warrant    was
    independent of the illegal entry.           The police officers' subjective
    intent to seek a warrant is a factual determination subject to
    clear error review.          Siciliano, 
    578 F.3d at 69
    .
    -12-
    The district court explained its ruling on that issue as
    follows:
    Here, there can be no doubt but that a warrant
    would have been sought even had the agents not
    observed the packages of cocaine in the
    garage. Too much evidence had been gathered
    and too much corroborating conduct on the part
    of the defendants had been observed for agents
    to simply take the chance that what was
    delivered . . . to the garage at 30 Arch
    Street was some innocent commodity.
    Jadlowe    argues    that   the   record    does     not   support   the   court's
    finding.     He     acknowledges     that    Agent    Simmons,   the   lead    law
    enforcement officer in the investigation, testified that he would
    have sought a warrant even had the officers not seen the bricks of
    cocaine in the garage.            Jadlowe claims, however, that Simmons'
    assertion is belied by the officer's earlier testimony that the
    operational plan called for seizing the cocaine in a motor vehicle
    stop after Gonsalves or Ferreira retrieved the drugs from the
    garage.16 He emphasizes the absence of direct evidence that, at the
    time they entered the garage, the agents intended to obtain a
    warrant and cites cases in which such contemporaneous evidence was
    16
    At the suppression hearing in September 2007, Simmons
    testified as follows:
    The plan at that time was, if the cocaine was
    unloaded at that address, it was anticipated that either
    Mr. Gonsalves or Mr. Ferreira would go to that address to
    retrieve the cocaine. At that point, once they retrieved
    the cocaine to move it to another location, we were going
    to do a motor vehicle stop of their vehicle in order to
    obtain the cocaine.
    -13-
    present.   See, e.g., United States v. Walton, 
    56 F.3d 551
    , 554 (4th
    Cir. 1995) (noting that agents had been preparing the search
    warrant affidavit for several days before an unlawful garage
    entry); United States v. Ford, 
    22 F.3d 374
    , 378 (1st Cir. 1994)
    (noting that, prior to unlawful entry, police had told defendant of
    intent to obtain a warrant).
    As an initial matter, we agree that Simmons's statement
    of his subjective intent is not necessarily dispositive.        See
    Murray, 
    487 U.S. at
    540 n.2; Dessesaure, 
    429 F.3d at 369
    .    We can
    also accept Jadlowe's assertion that the officers had neither begun
    the process of securing a warrant nor even formed the intent to
    obtain one before the quickly developing events of November 4
    unfolded contrary to their plans.17    Our cases, however, reject as
    "too rigid" the requirement that the officers be actively pursuing
    a warrant at the time of the unlawful entry, United States v.
    Silvestri, 
    787 F.2d 736
    , 746 (1st Cir. 1986), and favor instead a
    "flexible standard" based on "[t]he specific facts of each case,"
    Ford, 
    22 F.3d at 377
    .18   "[T]here is no necessary requirement that
    17
    At trial, in July 2008, Simmons testified that the plan
    conceived the night of November 3 was to "allow the delivery to
    take place, secure the address into which it was brought to, and
    then apply for a warrant that day." We assume, in Jadlowe's favor,
    that the intent to secure a warrant did not develop until the next
    day.
    18
    Silvestri and Ford both involved the "inevitable discovery"
    doctrine rather than the "independent source" doctrine, but we have
    recognized that the two doctrines are "close relative[s],"
    Siciliano, 
    578 F.3d at
    68 n.4. The inevitable discovery doctrine
    -14-
    the warrant application process have already been initiated at the
    time the illegal search took place."   Silvestri, 
    787 F.2d at 746
    .
    Here, we discern no clear error in the district court's
    finding that the circumstances as a whole left "no doubt" that the
    officers would have sought a warrant – as they eventually did –
    once they realized that they needed to enter the garage to gain
    possession of the drugs.   The record permitted the district court
    to find that the officers had not applied for a warrant earlier
    because they expected to arrest one or more of the conspirators and
    seize the drugs in a vehicle stop. Although the officers' strategy
    changed as the events of November 4 unfolded, their testimony
    reflects an assumption that cocaine would be – and then was –
    delivered to Jadlowe's garage.    Simmons testified that when the
    wiretaps revealed the conspirators' intent to move the cocaine from
    the garage to a different, less accessible location, the officers
    determined that they might need to take action at 30 Arch Street.
    Barbuti's testimony similarly reflects a belief that there was
    applies when the evidence at issue was not later obtained
    independently, but it "'inevitably would have been discovered by
    lawful means.'" 
    Id.
     (quoting Nix v. Williams, 
    467 U.S. 431
    , 444
    (1984)).   The Supreme Court similarly has observed that "[t]he
    inevitable discovery doctrine . . . is in reality an extrapolation
    from the independent source doctrine: Since the tainted evidence
    would be admissible if in fact discovered through an independent
    source, it should be admissible if it inevitably would have been
    discovered." Murray, 
    487 U.S. at 539
    . The flexibility we apply in
    the inevitable discovery context is at least as appropriate where
    the evidence was subsequently obtained by lawful, independent
    means.

    cocaine in the garage: "We formulated a plan that we did not want
    to allow the kilograms to leave that area for fear of losing them
    or having them be moved to a location where we weren't able to
    surveil."    The district court thus reasonably found that, well
    before the officers saw the cocaine, they resolved not to "take the
    chance that what was delivered . . . to the garage at 30 Arch
    Street was some innocent commodity."
    Jadlowe suggests that excusing the agents' unlawful entry
    here would seriously undermine the Fourth Amendment's warrant
    requirement, allowing officers to "always choose first to illegally
    search the premises" and to forego seeking a warrant when no
    evidence is found. The Supreme Court in Murray explicitly rejected
    such an argument:
    As petitioners see the incentives, law
    enforcement officers will routinely enter
    without a warrant to make sure that what they
    expect to be on the premises is in fact there.
    If it is not, they will have spared themselves
    the time and trouble of getting a warrant; if
    it is, they can get the warrant and use the
    evidence despite the unlawful entry. We see
    the incentives differently. An officer with
    probable cause sufficient to obtain a search
    warrant would be foolish to enter the premises
    first in an unlawful manner. By doing so, he
    would risk suppression of all evidence on the
    premises, both seen and unseen, since his
    action would add to the normal burden of
    convincing a magistrate that there is probable
    cause the much more onerous burden of
    convincing a trial court that no information
    gained from the illegal entry affected either
    the law enforcement officers' decision to seek
    a warrant or the magistrate's decision to
    grant it.     Nor would the officer without
    -16-
    sufficient probable cause to obtain a search
    warrant have any added incentive to conduct an
    unlawful entry, since whatever he finds cannot
    be used to establish probable cause before a
    magistrate.
    
    487 U.S. at 539-40
    .
    Nor are we persuaded by Jadlowe's attempt to depict this
    as the egregious case where suppression is necessary to vindicate
    the principles underlying the exclusionary rule.              In United States
    v. Madrid, 
    152 F.3d 1034
     (8th Cir. 1998), the case on which he
    primarily relies, the evidence indicated that, while awaiting a
    warrant, "officers went upstairs and downstairs [in a residence] on
    two or three occasions, detained and searched the occupants, seized
    wallets and placed them in envelopes marked 'evidence,' and leafed
    through personal mail and a notebook."              
    Id. at 1040
    .     Here, by
    contrast,    the   district    court   found    that    the    officers   left
    undisturbed the targeted, plain-view evidence, and "[t]he most that
    agents did that might be said to have compromised the crime scene
    was   to    rearrange   some    furniture      to   make   themselves     more
    comfortable."19
    In sum, while the district court correctly noted that
    "the more appropriate course would have been to secure the garage
    from the perimeter," it properly applied the independent source
    19
    Jadlowe's counsel elicited testimony from Agent Barbuti
    acknowledging that the officers were responsible for placing a
    white plastic chair, a radio, and a bottle of Coca-Cola near the
    cocaine so that they would be "more comfortable while hanging out
    in the garage."

    doctrine in refusing to suppress the cocaine seized from Jadlowe's
    garage.
    B. The Cell Phone
    A cell phone linked with phone number (508) 536-1022
    ("the 1022 phone") was seized by the agents sometime during the
    events surrounding Jadlowe's arrest at 30 Arch Street on November
    4.   Relying on the testimony of Agent Barbuti, the district court
    found that the phone was "seized from [Jadlowe's] person" in a
    lawful search incident to his arrest.                See United States v.
    Robinson, 
    414 U.S. 218
    , 235 (1973) (holding that a search incident
    to "[a] custodial arrest of a suspect based on probable cause" is
    reasonable   under   the      Fourth     Amendment);    United    States    v.
    Nascimento, 
    491 F.3d 25
    , 49 (1st Cir. 2007) ("Officers effecting an
    arrest are entitled to make a search incident to that arrest.").
    In its written ruling on the suppression motion, the court stated
    that Barbuti had testified that Lieutenant Robert Andrade, the
    arresting officer, "took the phone from Jadlowe during the search
    and handed it to him [Barbuti] for safekeeping."
    Jadlowe   points    out     that   the   testimony   presented   by
    Barbuti and Andrade differed from the court's description and
    argues that, given the actual record, the court clearly erred in
    finding that the seizure of the phone was lawful.           Barbuti in fact
    testified that he was uncertain about who had given him the phone
    -18-
    or when he had received it,20 and Andrade testified that he had no
    memory of taking the phone from Jadlowe.21                In light of this
    testimony, Jadlowe argues, the government failed to meet its burden
    of proving that the phone was seized legally.             See, e.g., United
    States v. Lopez, 
    380 F.3d 538
    , 543 (1st Cir. 2004) (noting the
    government's burden to prove the lawfulness of a search).
    Although the officers' testimony leaves some ambiguity as
    to   exactly   when   and   how   Barbuti   acquired     the   phone,   we   are
    comfortable that the district court's finding that it was seized
    from Jadlowe's person at the time of his arrest was not clearly
    erroneous.     See United States v. Romain, 
    393 F.3d 63
    , 69 (1st Cir.
    2004) (describing the relevant inquiry as "whether the evidence
    presented at the suppression hearing fairly supports the court's
    finding").      As    the   government   points   out,    Barbuti   testified
    unequivocally that he had been told the phone had been taken from
    Jadlowe's person, and Andrade testified that he knew "there was a
    cell phone at the location."       Jadlowe himself represented that the
    20
    Barbuti stated: "At some point, I don't know if it was
    [right after the pat-frisk] or immediately after doing a protective
    sweep of the residence, I was handed the cell phone from Mr.
    Jadlowe's person." He said he did not remember who handed it to
    him, but confirmed that it was "represented to [him] that it had
    come from Mr. Jadlowe's person."
    21
    When asked if a cell phone was "found on Mr. Jadlowe
    subsequent to your arrest of him," Andrade responded: "I know there
    was a cell phone at the location. I don't recall it being on Mr.
    Jadlowe."   He reiterated that reply in response to a follow-up
    question: "I don't recall a cell phone being found on his person."
    -19-
    phone had been on "his person" in his motion to suppress (a point
    noted        by   the   district   court).22   Moreover,   the   scope   of   a
    permissible search incident to an arrest is not limited to the
    arrestee's person, but includes "'the area from within which he
    might gain possession of a weapon or destructible evidence.'"
    Nascimento, 
    491 F.3d at 49
     (quoting Chimel v. California, 
    395 U.S. 752
    , 763 (1969)).          There is no evidence that the officers entered
    either of the Jadlowe houses before obtaining the warrant, and the
    record therefore supports the view that the phone was found near
    Jadlowe, even if not on his person.
    To succeed in challenging the denial of a suppression
    motion, a defendant "must show that no reasonable view of the
    evidence supports the district court's decision." United States v.
    Dunbar, 
    553 F.3d 48
    , 55 (1st Cir. 2009) (quotation marks and
    citation omitted); United States v. Larios, 
    593 F.3d 82
    , 92 (1st
    Cir. 2010).         Jadlowe has not made that showing here.
    C. The Phone Records
    At trial, the government introduced, as Exhibit 12,
    Sprint Nextel phone records that Jadlowe claims should have been
    suppressed because they were the fruit of the government's illegal
    22
    In his motion to suppress, Jadlowe stated: "The defendant
    also moves to suppress any evidence seized from his person on
    November 4th, 2005, including a cell phone."      His affidavit in
    support of the motion states that, "[o]n information and belief,
    the government intends to use evidence seized from the property and
    from my person against me at trial."
    -20-
    search of his homes on November 5. Exhibit 12 included information
    about     the    1022   phone,    which   was    the    one   seized   incident   to
    Jadlowe's arrest, and referred to a second phone with the number
    (508) 982-1964 ("the           1964 phone").      Phone records related to the
    1964 phone had been seized from Jadlowe's residence, but the court
    suppressed them in ruling that the search of the homes was not
    supported by probable cause.           Simmons testified, however, that the
    government had relied on those improperly seized records concerning
    the 1964 phone when it issued a single subpoena to Sprint for
    information about the two phone numbers.
    It   appears     undisputed      that   the    government's    only
    information about the 1964 phone derived from the illegal search
    and, hence, no evidence about that phone number should have been
    admitted at trial.         The information in Exhibit 12 about the 1022
    phone, however, derived from a court-authorized pen register of
    Gonsalves's cell phone in August 2005 and, as such, was not a fruit
    of the illegal search of Jadlowe's home.23
    Technically,     therefore,      Exhibit      12   contained   both
    admissible and inadmissible evidence, and Jadlowe may be correct
    that the court erred in allowing it into evidence.                     But any such
    error was certainly harmless.              With respect to the 1964 phone,
    23
    The pen register identified a phone with an IMSI number –
    which is like a serial number – of 316010102274660. The Sprint
    records connected that IMSI number to the 1022 phone and to the
    phone's use as a Direct Connect device with the number
    183*913*2639.
    -21-
    Exhibit 12 says only that "[n]o records were found . . . during the
    requested time period." The bulk of the information on the exhibit
    relates to the 1022 phone.      The document identifies the 1022
    account holder as Marc Souza, whose listed date of birth is the
    same as Jadlowe's.    That section of the document also links the
    IMSE number from the pen register with the 1022 phone seized from
    Jadlowe, thereby linking him with intercepted calls to and from
    Gonsalves and Ferreira.24   Hence, the damaging information in the
    exhibit was all lawfully derived.
    Jadlowe attempts to sidestep this critical dichotomy
    between the admissible and inadmissible information in Exhibit 12
    by arguing that the document implicitly suggests that the two phone
    numbers are linked.   Even if that were true, it would not matter.
    The exhibit in effect said nothing about the 1964 number, there was
    no substantive testimony about it, and the government did not rely
    on it.    We agree with the government that, even if admission of
    Exhibit 12 were error, it did not influence the verdict and was
    24
    Each of the two sections of the document, which are
    separated by a line of asterisks, begins with a listing of "Request
    Type," followed by the explanation "Subscription Info (Basic)."
    Each lists a "Date Range" and "Subject Number." The top section
    identifies the number as "5089821964" and the bottom section lists
    "316010102274660" as the number.      The top section then has a
    listing for "Comments," which is followed by the "[n]o records were
    found" entry.     The bottom section lists an account number,
    subscriber name, address, comments (the "comment" is that the
    account was established in June 2005), and a variety of other
    information, including the full 1022 phone number and the Direct
    Connect number.
    -22-
    therefore harmless.          See, e.g., United States v. Hicks, 
    575 F.3d 130
    , 143 (1st Cir. 2009).
    III.
    Jadlowe    argues      that     the     district   court    committed
    reversible error by telling the jurors that they could discuss the
    evidence as the trial progressed, before they commenced formal
    deliberations, so long as they did not express an ultimate opinion
    about the outcome of the case.              Preserved claims of instructional
    error are reviewed under a two-tiered standard: we consider de novo
    whether "an instruction embodied an error of law," but "we review
    for   abuse    of    discretion      'whether       the   instructions    adequately
    explained the law or whether they tended to confuse or mislead the
    jury on the controlling issues.'" United States v. Silva, 
    554 F.3d 13
    , 21 (1st Cir. 2009) (quoting United States v. Ranney, 
    298 F.3d 74
    , 79 (1st Cir. 2002)).
    Ordinarily,     even    if    we    find    instructional    error,   a
    defendant is entitled to a new trial "only if it had a prejudicial
    effect."      Bastien v. Goddard, 
    279 F.3d 10
    , 16 (1st Cir. 2002); see
    also Fed. R. Crim. P. 52(a) ("Any error, defect, irregularity, or
    variance      that    does    not    affect       substantial    rights    must     be
    disregarded.").         An exception exists for errors that are "so
    intrinsically harmful as to require automatic reversal . . .
    without regard to their effect on the outcome."                   Neder v. United
    -23-
    States, 
    527 U.S. 1
    , 7 (1999); see also United States v. Brandao,
    
    539 F.3d 44
    , 58 (1st Cir. 2008).
    A. Did Instructional Error Occur?
    The   challenged   instruction   was   delivered   before   the
    opening statements as part of the court's explanation of how the
    case would proceed:
    I just have a few special instructions
    about your conduct as jurors. The first one
    is the hardest. You are not to discuss the
    case with each other or anyone else until you
    retire to the jury room at the end of the case
    to deliberate on your verdict.
    This rule is not as strict as it
    sounds. When I say you are not to discuss the
    case, I mean it in this sense. You are not to
    express an ultimate opinion about the outcome
    of the case.
    Personally, even this rule, the way I
    state it, I don't think is a terribly good
    rule. I understand the reason for it. The
    thought is that because some of us tend to be
    more opinionated and assertive than others,
    jurors who are more assertive will tend to
    influence the opinions of fellow jurors if
    jurors are talking about the case before they
    hear all of the evidence. I think this, in
    fact, underestimates the intelligence of
    almost all the jurors that I have worked with
    over the years, but, nonetheless, this is the
    federal rule. It's been abolished in a number
    of states, but it is the federal rule. So we
    have to respect it. Like I say, whether we
    agree with the wisdom of a rule or not, it is
    the rule, the rule we follow.
    But, again, don't over-interpret what I
    said. Of course you'll talk about interesting
    things that happened during the course of the
    trial, idiosyncracies of the judge and the
    lawyers, interesting things witnesses say,
    significant pieces of evidence. Just do not
    express an opinion about the case, again,
    -24-
    until you begin deliberations and each have an
    opportunity to make your opinions known.
    Jadlowe's counsel properly objected to the instruction,
    arguing that "it's inappropriate for the jurors to discuss the case
    in any way, shape, or form until all of the evidence is in, they've
    heard closing argument, and they'[v]e heard your Honor's charge."
    The court disagreed:
    No.   Human nature, if you tell them not to
    discuss the case, defies anything we know
    about human beings. What's important is that
    they not form any ultimate opinions about the
    case until they've heard all of the evidence
    and that they not express opinions about the
    resolution of the case to one another.    And
    that's – if you want me to repeat the thrust
    of that instruction again, I will, but that's
    what I meant.
    Defense counsel then elaborated on his concern:
    Your honor, my objection is I don't
    think   they    should   be   talking   about
    "interesting things that the witnesses said."
    I just think that that's not what the jury
    should be doing. They should be simply – they
    can talk about the weather or the Red Sox.
    They should not be talking about the case.
    The court concluded the colloquy as follows:
    I disagree, and I think that's the
    reason states, at least those who have a
    progressive view of jury service, have
    abolished that rule now. In fact, even as to
    ultimate opinions as to the case, which I
    restrict them from talking about. I think you
    will find that the modern trend is against the
    old-fashion rule.
    The   court's   instruction   was   unmistakably   erroneous,
    including the assumption that the "modern trend" in criminal cases
    -25-
    is to allow juror discussion.        For more than a century, it has been
    a common-law principle that "it is improper for jurors to discuss
    a case prior to its submission to them," a practice that safeguards
    a defendant's "entitle[ment] under the Fifth and Sixth Amendments
    to   the    Constitution   to   a   fair   trial   to   an   impartial   jury."
    Winebrenner v. United States, 
    147 F.2d 322
    , 329, 327 (8th Cir.
    1945); 
    id. at 329
     ("So general is the rule that jurors should not
    discuss a case prior to its submission to them, that it has been
    enacted into statute in practically all the states of the Union.").
    While jury innovations in some jurisdictions now include allowing
    jurors to discuss evidence among themselves throughout the trial,
    see, e.g., Ariz. R. Civ. P. 39(f),25 such developments have arisen
    25
    Rule 39(f) states:
    If the jurors are permitted to separate during the
    trial, they shall be admonished by the court that it is
    their duty not to converse with or permit themselves to
    be addressed by any person on any subject connected with
    the trial; except that the jurors shall be instructed
    that they will be permitted to discuss the evidence among
    themselves in the jury room during recesses from trial
    when all are present, as long as they reserve judgment
    about the outcome of the case until deliberations
    commence.   Notwithstanding the foregoing, the jurors'
    discussion of the evidence among themselves during
    recesses may be limited or prohibited by the court for
    good cause.
    See also, e.g., Colo. Jury Instr., Civil 1:4 (4th ed.) (allowing
    discussion of evidence "only among yourselves and only in the jury
    room when all of you are present"); N.D.R.Ct. 6.11 (permitting
    court, without objection, to allow predeliberation discussion in
    civil cases).
    -26-
    primarily in the context of civil cases,26 and even in that setting
    such discussions have "remain[ed] controversial." Kelly v. Foxboro
    Realty Assocs., LLC, 
    909 N.E.2d 523
    , 528 & 529 n.17 (Mass. 2009)
    ("While   the   parties   in   a   civil   case   may   consent   to   juror
    discussions during the trial, we would not approve of that practice
    in a criminal case.");27 see also, e.g., Valerie P. Hans & Neil
    Vidmar, The Verdict on Juries, 91 Judicature 226, 229 (2008)
    (noting that allowing jury discussions during trial remains one of
    the "more controversial" jury reforms); Juror Discussions During
    26
    The Arizona Supreme Court Committee on the More Effective
    Use of Juries recommended that discussion be permitted in both
    civil and criminal trials, but the court accepted the proposal only
    for civil trials. Shari Seidman Diamond et al., Juror Discussions
    During Civil Trials: Studying an Arizona Innovation, 
    45 Ariz. L. Rev. 1
    , 6 (2003) ("Juror Discussions During Civil Trials"). The
    American Bar Association also has endorsed discussion of the
    evidence during recesses in civil, but not in criminal cases. See
    American Bar Association, Principles for Juries and Jury Trials,
    Principle 13(F) (2005) (stating that jurors in civil cases may be
    instructed that they are permitted to discuss the evidence among
    themselves in the jury room with the same limitations as the
    Arizona rule).
    27
    Indeed, the results of a national survey of jury operations
    and practices (the "State-of-the-States Survey") conducted by the
    National Center for State Courts Center for Jury Studies, published
    in 2007, indicate that the practice is still rarely used.       The
    relevant report data was generated from 11,752 surveys completed by
    judges and lawyers involved in state and federal trials that took
    place primarily between 2002 and 2006. Gregory E. Mize et al., The
    State of the States Survey of Jury Improvement Efforts: A
    Compendium    Report     4    (April     2007),     available    at
    www.ncsconline.org/d_research/cjs/pdf/SOSCompendiumFinal.pdf.
    According to the report, jurors were allowed to discuss evidence
    before formal deliberations in 2.2 % of the civil trials and 0.7%
    of the criminal trials in state court, and in 1.3% of the civil
    trials and 0.3% of the criminal trials in federal court.

    At least for now, the prevailing view in the federal
    courts remains that it is improper for jurors to discuss the case
    other than during their formal deliberations.                In December 2009,
    the Judicial Conference Committee on Court Administration and Case
    Management       reaffirmed   the   general      no-discussion         rule   in   its
    proposed     model     jury   instruction       on   the   use    of     electronic
    technology. See Judicial Conference of the United States, Comm. on
    Court Admin. & Case Mgmt., Proposed Model Jury Instructions: The
    Use of Electronic Technology to Conduct Research on or Communicate

    The Massachusetts Supreme Judicial Court observed that the
    studies on innovative jury practices "have not established
    decisively that these jury techniques are beneficial or detrimental
    to the outcomes." Foxboro Realty Assocs., 909 N.E.2d at 528 n.13.
    Specifically with respect to the bar on juror discussions about the
    case while the trial is ongoing, it has been observed that the
    prohibition is "based upon historical assumption rather than any
    real understanding as to how task-oriented groups actually render
    decisions or how discussions prior to the jury instructions would
    actually be likely to impact that process."       Ted A. Donner &

    "violation     of   the    proper   process   for   jury   decision-making");
    Winebrenner, 
    147 F.2d at 328-29
    ; see also Jury Selection Strategy
    § 39:3 ("The rule as enunciated in Winebrenner has remained the
    standard in most courts in the United States . . . .").
    The traditional view that jury discussion of the case
    during the trial is improper arises from concerns that jurors will
    prematurely form judgments that will be difficult to dislodge later
    in the proceedings.         See Resko, 3 F.3d at 689; Winebrenner, 
    147 F.2d at 328-29
    .           The court in Resko cogently summarized these
    concerns in a criminal case:
    First, since the prosecution presents its
    evidence first, any premature discussions are
    likely to occur before the defendant has a
    chance to present all of his or her evidence,
    and it is likely that any initial opinions
    formed by the jurors, which will likely
    influence other jurors, will be unfavorable to
    the defendant for this reason. Second, once a
    juror expresses his or her views in the
    presence of other jurors, he or she is likely
    to continue to adhere to that opinion and to
    pay greater attention to evidence presented
    that    comports     with    that     opinion.
    Consequently,   the   mere   act   of   openly
    expressing his or her views may tend to cause
    the juror to approach the case with less than
    a fully open mind and to adhere to the
    publicly expressed viewpoint.
    Third, the jury system is meant to involve
    decisionmaking as a collective, deliberative
    process   and  premature  discussions  among
    individual jurors may thwart that goal.
    Fourth, because the court provides the jury
    -30-
    with legal instructions only after all the
    evidence has been presented, jurors who engage
    in premature deliberations do so without the
    benefit of the court's instructions on the
    reasonable   doubt   standard.     Fifth,   if
    premature deliberations occur before the
    defendant has had an opportunity to present
    all of his or her evidence . . . and jurors
    form premature conclusions about the case, the
    burden of proof will have been, in effect,
    shifted from the government to the defendant,
    who has "the burden of changing by evidence
    the opinion thus formed." [Winebrenner, 147
    F.2d] at 328.30
    Finally, requiring the jury to refrain from
    prematurely discussing the case with fellow
    jurors in a criminal case helps protect a
    defendant's Sixth Amendment right to a fair
    trial as well as his or her due process right
    to place the burden on the government to prove
    its case beyond a reasonable doubt.
    3 F.3d at 689-90 (citations omitted).
    To be sure, not all of these reasons have force when the
    jurors are expressly told – as they are, for example, in Arizona –
    that they may discuss the evidence only in the presence of all
    jurors and that they must "reserve judgment about the outcome of
    the case until deliberations commence."   Ariz. R. Civ. P. 39(f).
    (Essentially, that is what the trial court told the jurors here.)
    30
    In this case, for example, Jadlowe points out that the
    government introduced a number of audio recordings to prove his
    involvement in the drug conspiracy and that the jurors could have
    concluded early in the case, after discussion among themselves,
    that those tapes reflected his participation.    Defense counsel,
    however, later sought to give those cryptic conversations a more
    benign interpretation by introducing other audio recordings
    indicating that Ferreira and Gonsalves were involved in various
    construction projects with the speaker believed to be Jadlowe and
    that furniture was being stored in the garage.
    -31-
    Yet, impressions formed about the evidence early on may nonetheless
    have a significant impact on the verdict, even if the jurors do not
    make their ultimate judgment until the end of the case.                         In our
    view, the traditional rationales remain persuasive.
    Of course, not all premature jury discussion about a case
    will compromise a defendant's fair trial rights, particularly where
    the conversation does not reflect a point of view about the
    evidence or the outcome.               See, e.g., United States v. Diaz, 
    597 F.3d 56
    ,   63    (1st      Cir.   2010)      (noting     that    jurors    apparently
    discussed only "a legal principle" and not "the merits of the case
    against the defendant").              Discussion such as that endorsed by the
    court in this case, however – about "interesting things witnesses
    say, significant pieces of evidence" – is inappropriate, even if
    the    conversation       was    not    what    we    ordinarily      would    consider
    premature "deliberations." Cf. State v. Washington, 
    438 A.2d 1144
    ,
    1148 (Conn. 1980) (noting that "[d]iscussion is an integral part of
    deliberations"         and    that,     "[i]n    a    constitutional        sense,   the
    distinction between discussion and deliberation is more apparent
    than real"). Moreover, while jury discussion that does not involve
    expressions       of    ultimate       opinions      may   be     found   harmless   in
    retrospect, it is a different question whether district courts may
    give the jury permission at the outset of the trial to talk about
    the case before formal deliberations begin.                     We now hold expressly
    that they may not.           We thus conclude that the court erred by giving
    -32-
    the jurors permission to discuss significant aspects of the case as
    the trial progressed.31
    B. Does the Error Require a New Trial?
    1. Was the Instruction Structural Error?
    Jadlowe argues that the court's instruction resulted in
    the denial of his due process rights and his right to a fair trial,
    and   that   it   should   be   considered   structural   error    requiring
    reversal without a showing of prejudice.        See, e.g., United States
    v. Marcus, 
    130 S. Ct. 2159
    , 2164 (2010) (describing structural
    errors as "a very limited class of errors that affect the framework
    within which the trial proceeds" (citations omitted) (internal
    quotation marks omitted); Neder, 
    527 U.S. at 8
    .                   He further
    contends that, even if the error is not deemed structural, a new
    trial is necessary because the government is unable to prove the
    absence of prejudice from the instruction.        See Neder, 
    527 U.S. at 7
     (noting that most constitutional errors may be disregarded where
    they are "harmless 'beyond a reasonable doubt'" (quoting Chapman v.
    California, 
    386 U.S. 18
    , 24 (1967)); United States v. Carpenter,
    
    403 F.3d 9
    , 11-12 (1st Cir. 2005).
    The question in identifying structural error is whether
    the error affects the "'framework'" of the trial, "'rather than
    31
    Although this case does not require us to impose an
    affirmative requirement that courts tell jurors not to discuss the
    case until deliberations formally begin, such an instruction is
    unquestionably the better practice.
    -33-
    simply   . . . the trial process itself.'" Neder, 
    527 U.S. at 8
    (quoting Arizona v. Fulminante, 
    499 U.S. 279
    , 310 (1991)). In such
    instances, "it is often 'difficul[t]' to 'asses[s] the effect of
    the error,'"   Marcus, 
    130 S. Ct. at 2165
     (quoting United States v.
    Gonzalez-Lopez, 
    548 U.S. 140
    , 149 n.4 (2006)), because the nature
    of a structural error is to "produce[] 'consequences that are
    necessarily unquantifiable and indeterminate,'" Neder, 
    527 U.S. at 11
     (quoting Sullivan v. Louisiana, 
    508 U.S. 275
    , 282 (1993)).   The
    frequently cited examples of such errors include the complete
    denial of counsel, a biased presiding judge, the denial of a public
    trial, and a defective instruction on reasonable doubt.   Id. at 8;
    see also, e.g., United States v. Curbelo, 
    343 F.3d 273
    , 281 (4th
    Cir. 2003) (concluding that trial court's decision to proceed with
    an eleven-person jury, over defendant's objection, was structural
    error requiring reversal).
    In the Supreme Court cases finding structural error, the
    errors themselves effected a deprivation of rights, so that "[n]o
    additional showing of prejudice is required to make the violation
    'complete.'" Gonzalez-Lopez, 
    548 U.S. at 146
    . The Court explained
    that characteristic of structural error in Gonzalez-Lopez, where it
    contrasted denial of a criminal defendant's choice of counsel –
    which it held to be structural error – with denial of the Sixth
    Amendment right to effective representation of counsel – which
    requires an additional showing of prejudice.       
    Id. at 147-48
    .
    -34-
    Deprivation of the right of choice is "'complete,'" the Court
    explained, "when the defendant is erroneously prevented from being
    represented by the lawyer he wants, regardless of the quality of
    the representation he received."                  
    Id. at 148
    .         By contrast,
    violation of "the right to effective counsel" depends on the
    competence of "whatever lawyer is chosen or appointed."                   
    Id.
    The   type    of    error    at    issue   here   has    "framework"
    implications.       If the court's faulty instruction results in early
    discussion of the evidence or witnesses by the jurors, their later
    deliberations may be prejudiced in ways that would be difficult to
    identify or quantify.             The jury's deliberative process – the
    collective, objective review of the evidence of record, evaluated
    as a whole, and guided by the court's closing instructions – may be
    compromised as a result of prematurely formed impressions.                      That
    potential harm is unlike the erroneous introduction of a piece of
    evidence or a flawed instruction that misstates or omits an element
    of the crime.       Such errors are discrete trial events whose effect
    on the outcome of the trial may be evaluated in light of the
    properly admitted evidence or the instruction as a whole.                         By
    contrast, premature discussion raises the possibility that the
    jurors will view all of the evidence through a distorted lens, much
    like   what    occurs      when   the   jury     is   improperly   instructed     on
    reasonable doubt.          See Neder, 
    527 U.S. at 10-11
     (noting that a
    flawed reasonable doubt instruction is "not subject to harmless-
    -35-
    error analysis because it 'vitiates all the jury's findings'"
    (quoting Sullivan, 
    508 U.S. at 281
    )). Where the possibility exists
    that premature jury discussions shifted to the defendant "the
    burden    of     changing    by   evidence   the    opinion    thus     formed,"
    Winebrenner, 
    147 F.2d at 328
    , the possibility exists that the trial
    was "an unreliable vehicle for determining guilt or innocence,"
    Neder, 
    527 U.S. at 9
    .
    Yet, the error here differs in a significant way from
    those the Supreme Court has labeled structural.                   Although the
    instruction opens the door to discussion "taint[ing] the process by
    which    guilt    [is]    determined,"   Curbelo,    
    343 F.3d at 285
    ,   the
    defendant will not necessarily be denied a fair trial as a result
    of the error.       Despite the instruction, juror discussion may not
    take place at all, and even if some preliminary conversation about
    the case occurs, it may be tangential to the jurors' determination
    of guilt or innocence.        Unlike the complete denial of counsel or a
    public    trial,    for   example,   the   harm    triggered   by   the   flawed
    instruction does not occur – i.e., the constitutional violation is
    not "complete" – until prejudicial discussion occurs.                  It is not
    necessarily the case, therefore, that "all or almost all such
    errors always 'affec[t] the framework within which the trial
    proceeds,' or 'necessarily render a criminal trial fundamentally
    unfair.'" Marcus, 
    130 S. Ct. at 2166
     (quoting Fulminante, 
    499 U.S. at 310
    , and Neder, 
    527 U.S. at 9
    ).
    -36-
    Jadlowe contends that the error must nonetheless be
    considered structural because a defendant would never be able to
    probe the jury's deliberations to prove prejudice.         Inquiries into
    jury deliberations are, in fact, narrowly restricted by Federal
    Rule of Evidence 606(b), which bars juror testimony "as to any
    matter or statement occurring during the course of the jury's
    deliberations."      The relevant inquiry, however, is not into the
    nature   of    the   formal   deliberations   that    occurred   once    the
    presentation of evidence concluded, but the nature of any juror
    discussion about the case prior to the formal deliberations.
    Probing such premature discussions is neither impermissible nor
    impossible.    Indeed, courts routinely examine allegations of juror
    misconduct      involving     improper     external     influences       and
    communications among jurors, and we see no relevant distinction
    between those contexts and this one.       The threshold question would
    be whether any premature discussion took place.            If so, was it
    among all jurors or just a few?          Did discussion occur regularly
    through the proceedings, or only once – and at what point?               What
    was the content of the discussion?
    We thus conclude that Supreme Court precedent "insist[s]
    upon a showing of individual prejudice" when a court improperly
    instructs jurors in a criminal case that they may discuss the
    evidence before formal deliberations commence.         Marcus, 
    130 S. Ct. at 2166
    .     Indeed,   although   the    practice   remains    rare,   the
    -37-
    authorization of jury discussion in criminal cases by some courts
    and the Arizona Supreme Court Committee's recommendation that it be
    permitted     in   both   civil     and    criminal    trials   reinforce    our
    conclusion that the instruction here should not be classified as
    structural error requiring automatic reversal of the defendant's
    conviction.    See supra nn. 25, 26 & related text; cf. Resko, 3 F.3d
    at 695 ("[W]e are unwilling to assume the existence of prejudice
    because we are far less certain that premature deliberations will
    lead to prejudice in every, or nearly every, instance."); United
    States v. Cruz, 
    156 F.3d 22
    , 28 (1st Cir. 1998) (upholding as
    adequate remedy the dismissal of three jurors who were heard
    discussing the case during a recess).
    2. Prejudice
    When a defendant properly preserves an objection to a
    trial error, the government bears the burden of proving that the
    error was harmless.         United States v. Olano, 
    507 U.S. 725
    , 734
    (1993); Curbelo, 
    343 F.3d at 278
    ; United States v. Colón-Muñoz, 
    192 F.3d 210
    , 222 (1st Cir. 1999). For most constitutional errors, the
    government    must   show    that    the    error     was   harmless    beyond   a
    reasonable doubt, Chapman, 
    386 U.S. at 24
    , and for most non-
    constitutional errors, the government must show that the error "did
    not have a 'substantial and injurious effect or influence in
    determining the jury's verdict,'" Curbelo, 
    343 F.3d at 278
     (quoting
    Kotteakos v. United States, 
    328 U.S. 750
    , 776 (1946)).                 The choice
    -38-
    of standard need not detain us because, on this record, the outcome
    is the same under either one.
    Neither the defendant nor the government asked the court
    to question the jurors about whether they had discussed any aspect
    of    the   case    during   the   five   days   of   trial,   and   no   inquiry
    consequently was made into the content of any conversations they
    may have had.       Such an inquiry could have revealed that the jurors
    discussed only tangential matters, allowing the government to
    easily satisfy its burden to show an absence of prejudice from the
    court's erroneous instruction.              In some cases, such an inquiry
    could produce evidence that would advance the defendant's claim of
    prejudicial error. Given the potential significance of the jurors'
    actual response to an instruction allowing them to converse about
    the trial as it unfolds, both the prosecutor and defense counsel
    would be well advised to request a jury inquiry whenever a court
    gives an instruction like the one challenged in this case.
    Here, the record is silent on whether the jurors engaged
    in premature discussions of the case and, hence, we must resolve
    the   issue    of   prejudice      by   examining   the   information     that   is
    available to us.         Our starting point is the flawed instruction
    itself. The district court explicitly told the jurors, twice, "not
    to express an ultimate opinion about the outcome of the case,"
    directing them to wait "until you begin deliberations and each have
    an opportunity to make your opinions known."                Pursuant to well-
    -39-
    established precedent, "'we presume juries understand and follow
    the court's instructions.'" United States v. Gentles, 
    619 F.3d 75
    ,
    85 (1st Cir. 2010) (quoting            United States v. Vázquez-Botet, 
    532 F.3d 37
    , 56 (1st Cir. 2008)).          We thus presume that the jurors did
    not express opinions about Jadlowe's guilt or innocence.
    The court, however, told the jurors they could discuss
    "idiosyncracies of the judge and the lawyers, interesting things
    witnesses say, significant pieces of evidence." Thus, in assessing
    the impact of the court's error, the question is whether we can say
    with assurance that, even if discussion of those matters occurred,
    the jury's deliberative process was not compromised.              Our concern
    is    whether   the    jurors   were   able   to   objectively   evaluate   the
    evidence as a whole when they engaged in formal deliberations,
    guided by the court's closing instructions.             See Resko, 3 F.3d at
    692    (focusing on the loss of "the jurors' impartiality" as the
    prejudice from an instruction allowing premature deliberations);
    Winebrenner,     
    147 F.2d at 327

    deliberation") (Woodrough, J., dissenting).
    We can easily discount the impact of any discussion about
    idiosyncrasies of the personnel.           Such observations would have had
    little or no effect on the jurors' ability to dispassionately
    -40-
    consider        the    evidence   against      Jadlowe       in   its   entirety.     We
    acknowledge, however, that the possible discussion of "significant
    pieces of evidence" or interesting testimony is more troubling.
    Such premature evidentiary deliberation could, in close cases, skew
    the final weighing of all the evidence.                      This is not, however, a
    close case.            Video surveillance and audiotapes, bolstered by
    compelling circumstantial evidence, placed Jadlowe in the midst of
    a drug scheme that involved the temporary storage of ten kilograms
    of cocaine in his garage.                    Despite flaws in the way certain
    evidence was presented, the record leaves no doubt about Jadlowe's
    complicity in the drug conspiracy.
    Thus, even if we assume that some jurors talked too soon
    about the inculpatory tendency of certain evidence, the force of
    the government's case as a whole meant that any comments made
    during the course of the proceedings almost certainly had no
    influence on the jurors' ultimate evaluation of Jadlowe's guilt or
    innocence.            Inescapably, the possibility of taint to the jury
    process        from     conversations         about     particular         evidence   was
    diminished, if not entirely negated, by the overwhelming proof of
    guilt        that   confronted    the    jurors       when   they   commenced      formal
    deliberations.32           Because      we    are   persuaded       that    the   court's
    32
    We emphasize that we consider the strength of the evidence
    in this context not to demonstrate that the evidence was sufficient
    to establish guilt beyond a reasonable doubt, but as part of our
    inquiry into whether premature discussion could have compromised
    the jury's deliberative process. Harm to the deliberative process
    -41-
    erroneous instruction was harmless beyond a reasonable doubt,
    Jadlowe is not entitled to a new trial on the basis of that error.
    IV.
    Jadlowe      asserts   that     the   district      court    erred   in
    admitting four types of evidence at trial: (1) a summary chart of
    wiretapped phone calls, (2) Agent Fallon's testimony identifying
    him on the surveillance video she recorded at 30 Arch Street on
    November    4,   2005,     (3)   Agent    Simmons's   testimony         identifying
    Jadlowe's   voice     in   wiretapped      calls,   and   (4)    transcripts     of
    wiretapped conversations that identified Jadlowe as one of the
    speakers.
    We review the district court's decisions to admit or
    exclude evidence for abuse of discretion.             Diaz, 
    597 F.3d at 64
    .
    A. The Summary Chart
    Jadlowe argues that Government Exhibit 10, a six-column
    chart listing details for twenty-two of the intercepted phone
    calls, contained testimonial hearsay that should have been ruled
    inadmissible at trial.           Specifically, he objects to the final
    column on the chart, which identifies the other phone number
    could occur even in the face of powerful evidence of guilt. The
    jury process almost certainly would be tainted, for example, by an
    instruction allowing discussion of the ultimate issue of guilt
    before all of the evidence was presented, regardless of the
    strength of the government's case.
    -42-
    involved in each of the listed wiretapped conversations.33   Eleven
    of the twenty-two calls were made to or from a number associated
    with the 1022 phone seized from Jadlowe.   There is no dispute about
    the admissibility of the first five columns, which report, inter
    alia, the date and time of each call and which targeted phone
    number, Ferreira's or Gonzalves's, was involved.   That information
    also was listed on a computerized printout labeled as Exhibit 9,
    which Jadlowe concedes was properly admitted.
    The information in Column 6 did not appear in written
    form on any other document admitted into evidence, and Jadlowe
    correctly points out that there is no evidence in the record about
    the creation of Column 6.   The government argues that Column 6 was
    admissible because the same information was contained in digital
    files that were part of Exhibit 8.     Exhibit 8 is a compact disk
    ("CD") that contains the oral recordings of the twenty-two phone
    calls listed on Exhibit 10; according to the government, the Column
    6 information for each call is appended to its oral recording on
    the CD.   The testimony at trial indicated that the data on the CD
    was not accessible to the jurors, however, and the government at
    oral argument essentially confirmed that was so.34
    33
    Column 6, labeled "Direction of Call/Phone No." also states
    whether the call was incoming or outgoing.
    34
    In its brief, the government describes Exhibit 9 as "a
    computer-generated print-out of some of the embedded data from
    th[e] calls."   The record does not reveal whether the Column 6
    information could have been retrieved in a similar format or how
    -43-
    Given the government's concession, we think there is
    force to the argument that Column 6 did not qualify as a summary of
    evidence already in the record.    We nonetheless decline to probe
    other theories in support of its admission. Column 6 provided only
    one link between Jadlowe and the conspiracy by identifying the 1022
    number as the other phone number in some of the intercepted calls.
    As we describe below in Section B, the audio and video surveillance
    produced much more direct evidence of Jadlowe's participation in
    the calls.35    Hence, any error in allowing the list into evidence
    was harmless.
    B. The Remaining Evidentiary Issues
    Jadlowe's three remaining contentions all concern the
    ways in which he was identified at trial as the individual who made
    the arrangements with Gonsalves and Ferreira for the cocaine
    delivery at 30 Arch Street.     Agent Fallon identified him in the
    surveillance videotape shown at trial by comparing a photograph of
    him to the video image.    Agent Simmons identified a voice on the
    tapes of the wiretapped phone calls as Jadlowe's, even though he
    easy it would be to do so.
    35
    Exhibit 10's relative unimportance to the case is reflected
    in a colloquy that took place at the close of evidence.        When
    defense counsel renewed the objection to Exhibit 10, the district
    court commented that it did not view the document "as being a very
    critical piece of evidence linking anything to anything."       The
    prosecutor agreed and stated that he would not object to its being
    redacted or excluded.    The court said it would make a decision
    after reviewing Agent Fallon's testimony and, later that day, ruled
    the exhibit admissible without restriction.
    -44-
    had never spoken with Jadlowe in person; the transcripts of the
    wiretapped conversations given to the jury reflected Simmons's
    identification of Jadlowe as one of the speakers.
    Jadlowe argues that the visual and voice identifications
    constituted   improper    lay   opinion    testimony   because   neither
    officer's identification was based on prior personal experience
    with Jadlowe and "[t]he jury was perfectly capable of drawing its
    own independent conclusion[s] based on the evidence presented."
    United States v. Garcia-Ortiz, 
    528 F.3d 74
    , 80 (1st Cir. 2008); see
    also Fed. R. Evid. 701 (allowing lay opinion testimony if, inter
    alia, it is "rationally based on the perception of the witness" and
    "helpful to a clear understanding of the witness' testimony or the
    determination of a fact in issue").        He asserts that the district
    court also abused its discretion in allowing the government to
    provide the jury with transcripts that presented as fact that he
    was the speaker.
    We agree that the officers' identifications should not
    have been allowed as lay opinion testimony because neither Fallon
    nor Simmons was in a better position than the jurors to make the
    identity judgments.      Indeed, Fallon testified that she made the
    identification by comparing his image on the screen with a driver's
    license photo that was in evidence.       We are at a loss to understand
    the government's argument that Fallon was better situated than the
    jurors simply because she was watching the events as they were
    -45-
    occurring.    At the time, she was looking at the same video image
    seen by the jurors at trial; the Registry of Motor Vehicle's
    photograph also was in evidence.36          In addition, although the
    government is correct that "identification of a telephone caller
    may be [established] by circumstantial evidence," United States v.
    DiMuro, 
    540 F.2d 503
    , 514 (1st Cir. 1976) (quotation marks and
    citation omitted) (alteration in original), the circumstantial
    evidence on which Simmons relied to infer that Jadlowe was the
    speaker in the wiretapped conversations – the content of the calls
    and the physical surveillance reports – also was available to the
    jury.
    Nonetheless,     any   error   in   allowing   the   officers'
    identifications   or   the   related   transcripts   was   unquestionably
    harmless.     An abundance of circumstantial evidence pointed to
    Jadlowe as the individual whom Fallon saw clearing the garage at 30
    Arch Street and whom Simmons heard in the phone conversations with
    Ferreira and Gonsalves.
    In a phone conversation on October 8, for example, the
    caller whose voice Simmons identified as Jadlowe's reported to
    Gonsalves that he would be getting his hair braided and that he had
    been home all day on his birthday.         Both items of information in
    36
    Fallon also testified that her       identification was aided by
    information from other officers on          the scene confirming that
    Jadlowe was the person she was seeing        on the video screen. That
    reliance on others further diminishes       the foundation for her own
    identification.
    -46-
    the call were linked to Jadlowe.              According to motor vehicle
    records, Jadlowe's birthday was the day before, October 7, and
    Simmons, who had seen Jadlowe multiple times before, testified that
    he   saw   Jadlowe   with   newly   braided    hair   shortly   after   this
    conversation.    In a call with Gonsalves on November 4, the speaker
    Simmons identified as Jadlowe was addressed as "Uncle Marc," and in
    another call the same day, just before 2 p.m., that speaker told
    Gonsalves that he was "[t]aking care of the garage" and that he was
    "[d]oin' it right now."     According to Agent Fallon's testimony, it
    was at about that time that, with other officers' assistance, she
    identified Jadlowe as the individual she had seen moving items from
    the garage to the yard at 30 Arch Street.
    Simmons's ability to identify Jadlowe in each instance in
    which Jadlowe was designated on the transcript as the speaker was
    supported by the agent's admissible testimony that he had listened
    to 25 to 50 calls involving the number associated with the phone
    seized from Jadlowe at 30 Arch Street on November 4, 2005, and that
    over time he was able to recognize the callers in those wiretapped
    conversations after "hearing the same voices every day."                 He
    testified that he had heard no one on that phone           other than the
    speaker Gonsalves referred to as "Uncle Marc" in the November 4
    call.   Each of the calls attributed to Jadlowe was thus identified
    by Simmons as involving the same voice, including the other calls
    described above whose content was linked to Jadlowe.
    -47-
    Hence, even if it were improper for Simmons and Fallon to
    have offered their opinions that Jadlowe was the speaker in the
    wiretapped calls and the individual in the videotape, we are
    confident that any such error did not influence the verdict.              This
    is equally true of the jury's exposure to the transcripts.                Not
    only was there compelling circumstantial evidence that Jadlowe was
    properly identified as the speaker in the calls, but the district
    court also instructed the jurors at the time they received the
    transcripts that it was up to them "to make a determination as to
    whether the transcript is correct in its identification of Mr.
    Jadlowe as the speaker at the points at which he is so listed in
    the transcript."       The court emphasized that "the transcript is
    only an aid," and that the jurors would "have to look to other
    evidence in the case to ensure yourself that that indeed is true."
    The court repeated that caution in its charge at the close of
    evidence, telling the jurors that if they "believe that the speaker
    has   been   wrongly   identified,    keep   in   mind   that   it   is   your
    understanding of the recording that matters."
    On this record, there was no reversible error stemming
    from the challenged evidentiary rulings.
    V.
    Jadlowe has pressed serious concerns about the admission
    of evidence and the jury instructions, and on some of those issues
    we agree that the district court erred.           On the record before us,
    -48-
    however, we cannot agree that those errors require a new trial.
    The judgment of conviction is therefore affirmed.
    So ordered.
