     *
      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 and that, before the issue of prejudice can be

addressed, the defendant must show that such discussions in fact

occurred.      As the record here is silent on whether the jurors

engaged in discussion of the case during the trial, we do not reach

the prejudice question.         Hence, 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


      1
          All of Jadlowe's co-defendants pled guilty.

U.S.C. § 841(a)(1).               We set forth here the background of the

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.
       4
      A "pen register" is a device used, inter alia, to record the
dialing and other information transmitted by a targeted phone. 18

            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




testified that a "pen order" authorized law enforcement officers
"to track who was calling the phone number, what numbers were being
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."

                                         -5-
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.

                               -15-
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-

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).

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

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).

       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

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. Id. at

Civil Trials, 45 Ariz. L. Rev. at 77 ("Ultimately, like many other

proposals for change, the innovation permitting jurors to discuss

the   case    during     trial    has    both    desirable       and    undesirable

features.").28

             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

        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 &

other        circuits,    including         recent     decisions,    reveals     similar

disapproval of discussions by jurors about the case before formal

deliberations begin.             See, e.g., United States v. Carey, 337 F.

App'x 256, 260 (3d Cir. 2009) (noting that "[t]he evidence of

Cir. 2000) (describing predeliberations jury discussions as a

"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).

Yet, impressions formed about the evidence early on may nonetheless


     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-
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" (internal quotation marks and

citations 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 – from 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,


                                    -37-
the 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




                                    -38-
Kotteakos v. United States, 328 U.S. 750, 776 (1946)).    As we shall

explain, we need not decide which of these standards applies here.

          Neither the government nor the defendant asked the court

to question the jurors before they commenced formal deliberations

about whether they had discussed any aspect of the case during the

five days of trial proceedings.    The record is therefore silent on

that question. If we were to conclude that the defendant preserved

his objection to the erroneous instruction simply by objecting to

it, we could conclude that the government failed to meet its burden

to show harmless error based simply on the absence of evidence that

the jurors did not discuss the case.

          We decline, however, to adopt that approach and to take

the serious step of ordering a new trial without any evidence in

the record that the jurors engaged in improper discussions.      The

court gave the jurors permission to talk about the case, but it did

not tell them to do so.32   In our view, to justify a new trial based


     32
       We recognize that one reason given for reconsidering the bar
against allowing jurors to discuss the case as the trial proceeds
is that "the system needs to recognize reality – jurors talk."
N.D. Sup. Ct. Joint Proc. Comm., Minutes, at 11; see also Juror
Discussions During Civil Trials, 45 Ariz. L. Rev. at 10 ("Because
jurors find it difficult to adhere to an admonition not to discuss
evidence, permission to engage in such discussions bridges the gap
between the court's admonitions about forming premature judgments
and juror behavior."); United States v. Klee, 494 F.2d 394, 396
(9th Cir. 1974) (quoting the dissent's observation in Winebrenner
that "'[n]o normal honest Americans ever worked together in a
common inquiry for any length of time with their mouths sealed up
like automatons or oysters.'"). Even accepting that jurors advised
that they may discuss the case ordinarily will do so, we decline to
assume that they will have done so in every case.

                                 -39-
on prejudicial juror discussion, the defendant must make some

showing that the improper conduct in fact arose.          The defendant

could, for example, ask the trial judge to inquire of the jurors

whether any premature discussions had taken place.       If the court's

questioning reveals that such discussion occurred, the government

would bear the burden of proving that it was not prejudicial.       Even

if the court refuses to make the inquiry, the defendant will have

preserved his objection to the instruction by making the request,

and the government would have the burden of showing the absence of

prejudice.   The silent record would in that situation mean the

government could not satisfy its burden, and a new trial would be

necessary.

           In effect, we conclude that a standard analogous to plain

error applies when a defendant claims he was denied a fair trial

based on an instruction allowing improper jury discussion, but has

failed to show that any discussion took place.       This approach does

not diminish the importance of objecting in the first instance to

the   instruction   that   made   such   conduct   "permissible."    The

objection ensures that the burden will be on the government to

defend the integrity of the jury's deliberative process when the

defendant also shows, or makes an effort to show, that premature

discussion in fact occurred.      In our view, "this approach reaches

an appropriate balance between 'society's interest in punishing the

guilty [and] the method by which decisions of guilt are to be

            Here, the defendant has shown only that the court erred

in telling the jurors that they could discuss the case among

themselves       before      formal   deliberations       began.        Because     the

defendant did not also show that any such discussions took place,

he   cannot      show     that     prejudicial       predeliberations       discussion

occurred.     He is therefore not entitled to a new trial on that

basis.

            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




      33
       This case does not require us to decide how a trial court
should assess the prejudicial effect of particular statements made
during premature jury discussions of the case or what standard
should be used in evaluating harmless error. As noted above, the
common law rule arises from the view that predeliberation
discussion in criminal cases jeopardizes the defendant's Fifth and
Sixth Amendment rights to a fair trial before an impartial jury.
The improper instruction itself, however, does not cause
constitutional harm; the risk to a fair trial arises only if
conversations occur that could cause jurors to form premature
judgments about the case.      Whether every conversation should
trigger the harmless error standard for constitutional violations
is a question we leave for another day.

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

involved in each of the listed wiretapped conversations.34   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



     34
       Column 6, labeled "Direction of Call/Phone No." also states
whether the call was incoming or outgoing.

                                -42-
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.35

          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




     35
        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
easy it would be to do so.

                               -43-
the calls.36    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

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


     36
        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-
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

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.37      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


     37
       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.

                               -45-
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

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


                                         -46-
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.

           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


                                -47-
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,

however, we cannot agree that those errors require a new trial.

The judgment of conviction is therefore affirmed.

             So ordered.
