    OPINION
    _______________
    JORDAN, Circuit Judge.
    Gathon Dudley Shannon appeals his conviction and
    the sentence imposed on him by the United States District
    Court for the Western District of Pennsylvania. Among other
    things, he contends that the government violated his Fifth
    Amendment rights at trial by cross-examining him about his
    post-arrest silence.1 Because we agree that the government
    1
    By “post-arrest” silence, we mean Shannon’s silence
    following his arrest and receipt of the attendant warnings
    under Miranda v. Arizona of his right to remain silent. 
    384 U.S. 436
    , 467-68 (1966). Shannon also argues that the
    District Court abused its discretion by admitting into evidence
    2
    violated his constitutional right to remain silent, we must
    vacate the judgment of conviction and remand for a new trial.
    I.    BACKGROUND
    Whether Shannon’s conviction can stand is contingent
    on whether the constitutional error that infected his cross-
    examination was “harmless beyond a reasonable doubt.”2
    Chapman v. California, 
    386 U.S. 18
    , 24 (1967). We
    therefore provide a detailed overview of the evidence
    presented at trial.
    A.     Factual History
    In December 2009, the Pennsylvania State Police
    (“PSP”) along with the United States Drug Enforcement
    Administration (“DEA”) began investigating an increase in
    his two prior convictions despite their being more than twenty
    years old; that it erred in issuing certain supplemental jury
    instructions after the jury had indicated that it was
    deadlocked; and that it violated his Sixth Amendment rights
    by basing his sentence on a judicial finding of fact – which
    implicated a specific statutory maximum and minimum
    sentence – rather than on the jury’s verdict. We mention
    these issues later, see infra at n.9, but do not decide them
    because the Fifth Amendment violations apparent on the
    record require reversal.
    2
    As explained within, the government must “prove
    beyond a reasonable doubt that the error complained of did
    not contribute to the verdict obtained,” to sustain the
    conviction. Chapman v. California, 
    386 U.S. 18
    , 24 (1967).

    cocaine sales across Beaver County, Pennsylvania. Working
    with confidential informants, the DEA was able to identify
    the local distributor as Adrian Taylor, and, through a series of
    wiretaps, learned that a large shipment of cocaine was
    expected to arrive in Beaver County during the weekend of
    August 20-21, 2011.
    Using traditional surveillance techniques, the DEA
    watched Taylor leave his Beaver Falls home on August 20 to
    collect money from his street-level dealers in anticipation of
    the shipment’s arrival. According to Taylor – who ended up
    testifying on behalf of the government – he then drove to a
    hotel near the Pittsburgh International Airport carrying two
    bags, one full of cash that he had collected from his associates
    and the other containing items necessary to “wrap” the cash.3
    There, he met with the cocaine supplier, Vincent
    Middlebrooks from Houston, Texas, who counted the cash
    and wrapped it while Taylor waited. Taylor testified that,
    during drug deals like this, he “always only [met with]
    Middlebrooks.” (App. at 984.) According to Taylor, after the
    cash was prepared, Middlebrooks drove to Washington
    County, Pennsylvania, where he was expected to “grab[] the
    coke” and then come back and transfer the drugs to Taylor.
    (Id. at 985.)
    Shortly after midnight the following day, when the
    exchange of drugs for cash was evidently complete, a DEA
    team saw Taylor flag down Middlebrooks at a second hotel.
    The two conversed briefly, and Taylor left and drove home.
    The agents then observed Middlebrooks go back to the first
    3
    “Wrapping” the cash means shrink-wrapping it in
    preparation for exchanging the cash for drugs.
    4
    hotel. The next morning, agents saw Middlebrooks return his
    rental car at the Pittsburgh airport and embark on a flight back
    to Houston.
    Given that Taylor had succeeded in bringing multiple
    kilograms of cocaine into Beaver County, the DEA was able
    to persuade a judge that a “roving wiretap” on Taylor’s
    communications was warranted to follow the drugs and
    money and to learn more information about Middlebrooks.4
    In the meantime, by early September, Taylor’s Beaver
    County associates had already sold all the cocaine from the
    August shipment and were, as the government says,
    “clamoring for more.” (Gov’t’s Br. at 6.) Taylor thus
    immediately began preparing for the next deal, collecting as
    much cash as he could to bankroll another shipment.
    On September 27, 2011, Taylor texted Middlebrooks,
    asking when the next cocaine shipment was expected to arrive
    in Beaver County. That was the first communication between
    the two that the government had intercepted. The two then
    spoke by telephone, with Middlebrooks confirming that the
    next shipment would arrive within two days, on Thursday,
    September 29, 2011. During that telephone call, in which
    Taylor agreed to buy 16 kilograms of cocaine, Middlebrooks
    confirmed that he would fly to Cleveland, Ohio, on
    September 28 and proceed to drive to a hotel near Taylor’s
    house, where he would spend the night packaging the cash for
    the following day’s deal.
    4
    A regular wiretap involves tapping a particular phone
    whereas a roving wiretap authorizes the government to, in
    effect, tap a person, “intercept[ing] any and all identified
    telephones used by that person.” (App. at 284.)
    5
    On the night of September 28, 2011, DEA agents in
    Cleveland spotted Middlebrooks as he deplaned from a flight
    inbound from Houston, walking with a black roller-bag. The
    agents followed Middlebrooks as he drove a rental car two
    hours from the Cleveland airport to one of the Pittsburgh
    hotels where he had previously met Taylor. While en route,
    Middlebrooks spoke with Taylor on the phone and stated that
    he “got the car and everything.” (App. at 624.) Taylor
    responded by warning Middlebrooks to “keep your eye out.”
    (Id. at 625.)
    In the early morning hours of September 29, 2011,
    DEA agents watched as Taylor arrived at the hotel – again,
    carrying two bags – and joined Middlebrooks. After
    approximately ten minutes together, Taylor walked out
    without the two bags and returned to his vehicle. Several
    hours later, Middlebrooks called Taylor and told him that he
    was “on the move.” (Id. at 669.) Having wrapped the money
    into nine packets, Middlebrooks left the hotel with a single
    bag containing the cash. As he proceeded to drive to a truck
    stop in Eighty Four, Pennsylvania, in Washington County –
    the same county where the August 20-21 cocaine transaction
    had occurred – several DEA agents surreptitiously followed
    him.5
    According to the government, once Middlebrooks
    reached the truck stop, the agents were forced to “hang back
    and watch from a distance so as not to blow their cover.”
    5
    Eighty Four is a town in Washington County,
    Pennsylvania, and, by Shannon’s testimony, is also the name
    of the local truck stop.
    6
    (Gov’t’s Br. at 8.) From their vantage point, they saw
    Middlebrooks back his vehicle up to a tractor-trailer rig, open
    his trunk, and then hand the bag full of packaged cash to a
    man – later identified as Shannon – standing beside the rig.
    Notably, the agents said that they did not see Middlebrooks
    receive anything in return because their view was partially
    obstructed by a building and various parked trucks. The next
    thing the agents observed was Middlebrooks getting back into
    his car. The agents followed him as he rendezvoused with
    Taylor at the same hotel from which he had come. At that
    point, given that the money had already changed hands, the
    officers moved in to arrest both men. When Taylor and
    Middlebrooks were taken into custody, each was found with
    three different cell phones on their persons, including a Boost
    Mobile Phone on Middlebrooks. “[A] black bag containing a
    large amount of cocaine” was also found in the trunk of
    Middlebrooks’s car. (App. at 801.)
    Back at the truck stop, Shannon stored the bag inside
    the cab of his truck and remained waiting inside the rig.
    According to testimony Shannon later gave on the witness
    stand, he had traveled to Eighty Four, a truck stop he often
    frequented, only as a favor to someone named Phillip
    Williams, a trucker whom he became acquainted with while
    on the road and whom he had occasionally met in Houston.
    Shannon said that Williams had called him to ask whether, as
    a favor, he would pick up someone named “Vince,” another
    trucker, whose vehicle had supposedly broken down in
    Pittsburgh. Shannon testified that he did not know Vince but
    was willing to oblige Williams’s request because he himself
    had recently been stranded after his own truck broke down
    and he empathized with Vince’s predicament. According to
    Shannon, he had agreed to meet Vince at Eighty Four – not
    7
    exactly where Williams had requested, but a familiar haunt to
    Shannon – to give Vince a ride back to Houston.
    But upon meeting “Vince,” who turned out to be
    Middlebrooks, Shannon claimed to be puzzled. Not only did
    Middlebrooks arrive driving a car, which implied that he was
    in no need of a ride, but he also handed Shannon a bag and
    asked whether he would be willing to wait “about an hour” so
    that he could “take care of some other business.” (App. at
    1356.) Shannon testified that he agreed to wait because he
    had already gone out of his way to pick the man up. After
    some “[t]ime went by,” however, Shannon said he became
    concerned by the situation and opened the bag, worried that
    he might have been handed “dope.” (Id. at 1357-59.)
    Shannon testified that, when he saw that it was instead cash,
    he “put the money back in the bag[,] ... threw it up under [his]
    bed and got out of [his] truck.” (Id. at 1359.) According to
    Shannon, he began walking towards the truck stop’s store to
    call his girlfriend for help. He was arrested before he reached
    the building.
    Upon a search of Shannon’s vehicle and person, agents
    found the bag, which contained $669,340, as well as $1000 in
    the glove compartment of the truck and three phones – a
    Boost Mobile phone on the truck’s dashboard, an iPhone on
    the ground near where Shannon was arrested, and a Verizon
    Motorola phone.
    On December 14, 2011, a grand jury in the Western
    District of Pennsylvania handed down a superseding
    indictment that, inter alia, charged Shannon, Taylor, and
    Middlebrooks with Conspiracy to Distribute and Possess with
    Intent to Distribute Five Kilograms or More of Cocaine, in
    8
    violation of 21 U.S.C. § 846 (Count I), and Distribution and
    Possession with Intent to Distribute Five or More Grams of
    Cocaine, in violation of 21 U.S.C. §§ 841(a)(1) and
    841(b)(1)(A)(ii) (Count II). Both Middlebrooks and Taylor
    pleaded guilty, but Shannon chose to go to trial.
    B.     The Trial
    Shannon’s trial strategy was to emphasize that he was
    trying to do someone a favor and that he was simply caught in
    the wrong place at the wrong time. The government, on the
    other hand, endeavored to prove that he had been a drug
    courier for Middlebrooks since at least late 2009. To that
    end, the government placed particular focus on the
    circumstances surrounding Shannon’s arrest and its aftermath.
    For example, Taylor testified that, when he and
    Shannon were together in pre-trial detention, Shannon
    confessed he had been skimming cash from the proceeds of
    drug deals for some time in order to cover “gas money.”
    (App. at 1007.) The government argued that such skimming
    would explain the $1000 found in the truck’s glove
    compartment when Shannon was arrested. Shannon, of
    course, denies that interpretation and maintains that he only
    kept cash in the glove compartment in case of an emergency,
    ever since the trouble he encountered when his truck broke
    down.
    Like Taylor and Middlebrooks, Shannon was also
    arrested with three different cell phones on or near his person.
    The government presented testimony that “people who are
    involved in drug trafficking” often have multiple phones,
    including prepaid cell phones like Shannon’s Boost Mobile
    9
    phone, and “everyday” phones like Shannon’s iPhone. (App.
    at 234, 243.) The government also confirmed through
    telephone records that Shannon and Middlebrooks each used
    their respective Boost Mobile phones to contact only one
    other such phone, i.e., a companion phone. In fact, the
    government brought to light that, on multiple occasions,
    including during the August 20-21 and September 29 drug
    deals, signals from Shannon’s and Middlebrooks’s Boost
    Mobile phones were relayed by a cell tower in Eighty Four
    when the phones were used to “chirp”6 their companions.
    Shannon tried to explain to the jury why he needed
    three phones. He said that the Verizon Motorola phone was
    his “everyday” phone and was registered under his name,
    while the iPhone was used solely for “jobs purposes” and was
    registered under his former girlfriend’s name because she had
    better credit than he did at the time it was purchased. (App.
    at 1404-06.) As for the third phone, the Boost Mobile phone,
    Shannon claimed that it was purchased in May 2011 as a
    specially dedicated phone for speaking to his nephew Jeremy,
    whom Shannon said he considered as a son. According to
    Shannon, he bought two Boost Mobile phones in 2011, one
    for him and one for Jeremy, because Boost Mobile offered a
    pre-paid, month-to-month plan with unlimited minutes and
    “chirp” features, and he wanted Jeremy to learn how to
    “handle a phone” and the responsibility of paying for a phone
    before he switched Jeremy to his Verizon Wireless account.
    (App. at 1408.)       Although Shannon admitted that he
    intentionally registered the Boost Mobile phones under a
    6
    “Chirps is the walkie-talkie feature of the Boost
    Mobile phone.” (App. at 1230.)
    10
    pseudonym, he said he did so only because he was told that,
    as pre-paid phones, they could be registered under any name.
    Finally, the government confirmed during Shannon’s
    cross-examination that his logbooks – which, as a long-haul
    trucker, he was required to keep by his employer and the
    United States Department of Transportation – were often
    falsified. From the government’s perspective, Shannon’s
    decision to make “wrong entries” in the logbooks was proof
    that he was not making some side-trip to Eighty Four on the
    day of his arrest but was in fact regularly traveling there, as
    also evidenced by his Boost Mobile phone making use of a
    local cell tower nearly every time Middlebrooks flew into the
    Pittsburgh area. (App. at 1452.) Again, Shannon had an
    explanation for the falsified log entries. He admitted that he
    sometimes lied in his logbook but only to cover up his driving
    to Baltimore to visit his paramour, Mary Simpson. When
    asked by the government whether he lied in the logbook
    because he could not “put all that driving time down” and still
    do his “real job,” Shannon agreed. (Id.)
    After Shannon testified about his secret lover
    Simpson, his favor-seeking trucker friend Williams, and his
    beloved nephew Jeremy – all in an effort to explain some of
    the more damning circumstances surrounding his arrest – the
    government took the step that has become the main point of
    contention in this case: it asked him why he had not come
    forward earlier with his exculpatory version of the facts.
    Shannon’s counsel immediately objected to the government’s
    questions, citing the Fifth Amendment, but he was summarily
    overruled. Shannon was therefore pressed to explain his
    silence. He did so by saying that he had told his lawyer his
    version of the events in question.
    11
    Following closing arguments, and after several hours
    of deliberating, the jury came back and announced it was
    deadlocked. In response, the District Court gave the jury an
    Allen charge,7 which it claimed was “almost exactly,” if not
    “word-for-word,” the model jury instruction provided in our
    Circuit. (App. at 1645.) Shortly thereafter, the jury returned
    and found Shannon guilty on Count I (conspiracy) but not
    guilty on Count II (possession). Notably, the jury found that
    the government had only proven beyond a reasonable doubt
    that Shannon was responsible for less than 500 grams of
    cocaine, and so indicated on the verdict slip, which provided
    the option of finding him responsible for more than 5
    kilograms (as alleged in the indictment), more than 500
    grams, or less than 500 grams. The District Court disagreed,
    however, saying that “there [was] absolutely no evidentiary
    basis to support [the jury’s] finding” of less than 500 grams.
    (App. at 1744.) It therefore held him accountable for 16
    kilograms of cocaine and sentenced him to 240 months’
    imprisonment as well as six years of supervised release.
    Shannon timely appealed.
    II.    DISCUSSION8

    See Allen v. United States, 
    164 U.S. 492
    , 497 (1896)
    (approving a supplemental instruction given to encourage a
    deadlocked jury to resolve its differences and reach a verdict).
    8
    The District Court had jurisdiction over this matter
    under 18 U.S.C. § 3231. We exercise jurisdiction pursuant to
    28 U.S.C. § 1291.
    12
    While Shannon raises several issues on appeal, we
    focus on his Fifth Amendment argument because the
    government’s questioning of Shannon about his post-arrest
    silence is alone enough to require that the conviction be set
    aside.9
    9
    The parties contest whether the District Court
    violated Shannon’s Sixth Amendment rights at sentencing
    and, in that regard, have raised arguments regarding the
    applicability of Alleyne v. United States, 
    133 S. Ct. 2151
    (2013) (holding that any fact implicating a statutory
    maximum or mandatory minimum sentence is an element of
    an offense that must be found by a jury beyond a reasonable
    doubt). We decline to address those and other arguments
    raised by Shannon, since we must vacate his conviction.
    Although we refrain from deciding those remaining
    arguments, we would be remiss if we did not make the
    following observations.
    First, in light of the Court’s finding that Shannon’s two
    prior convictions, both more than twenty years old, could be
    admitted under Rules 404(b) and 609(b) of the Federal Rules
    of Evidence, it is worth noting the narrow purpose and
    specific contours of each rule. Rule 609, which governs the
    use of convictions as evidence of truthfulness for
    impeachment purposes, limits the admission of a conviction
    more than 10 years old unless “its probative value, supported
    by specific facts and circumstances, substantially outweighs
    its prejudicial effect.” Fed. R. Evid. 609(b)(1). The Advisory
    Committee Notes for Rule 609(b) emphasize that
    “convictions over 10 years old will be admitted very rarely
    and only in exceptional circumstances.” Fed. R. Evid. 609(b)
    advisory committee’s note (emphasis added). Similarly,
    while Rule 404(b) allows evidence of earlier convictions to be
    13
    admitted as impeachment evidence “for another purpose”
    besides showing predisposition to commit the crime – such as
    proving “absence of mistake” or “lack of accident” – we have
    held that:
    prior act evidence [under Rule 404(b)] is
    inadmissible unless the evidence is (1) offered
    for a proper non-propensity purpose that is at
    issue in the case; (2) relevant to that identified
    purpose; (3) sufficiently probative under Rule
    403 such that its probative value is not
    outweighed by any inherent danger of unfair
    prejudice; and (4) accompanied by a limiting
    instruction, if requested.
    United States v. Caldwell, No. 13-1918, -- F.3d -- , 
    2014 WL 3674684
    , at *7 (3d Cir. July 24, 2014). Furthermore, we have
    emphasized that the non-propensity “purpose” for which
    404(b) evidence is admitted must be narrowly construed and
    explicitly recorded by the Court. See, e.g., United States v.
    Davis, 
    726 F.3d 434
    , 443 (3d Cir. 2013) (noting that prior
    experience with small amounts of a drug would not have
    provided the requisite knowledge under Rule 404(b) to help a
    defendant identify a large amount of that drug since “[t]he
    packaging or quantity might be different, and objects in
    greater quantities often have an appearance or smell of their
    own”); United States v. Givan, 
    320 F.3d 452
    , 466 (3d Cir.
    2003) (McKee, J., concurring in part and dissenting in part)
    (noting that the exception for “absence of mistake” under
    Rule 404(b) requires the government to demonstrate the
    defendant’s same “modus operandi” in a prior crime). A
    court should hesitate to admit twenty-year-old convictions
    when that evidence looks like propensity evidence. Under
    14
    The guarantee that “[n]o person ... shall be compelled
    in any criminal case to be a witness against himself,” U.S.
    Const. amend. V, is so “fundamental to our system” of
    government that, in the landmark case of Miranda v. Arizona,
    
    384 U.S. 436
    , the Supreme Court established the now-famous
    rule that a defendant must be informed upon arrest that he has
    the right to remain silent. 
    Miranda, 384 U.S. at 467-68
    .
    Later, reviewing a prosecution under state law, the Court in
    Doyle v. Ohio announced that, because of the protections of
    such circumstances, the evidence must ordinarily be
    excluded. See United States v. Sampson, 
    980 F.2d 883
    , 887
    (3d Cir. 1992) (“Hence, where the evidence only goes to
    show character, or that the defendant had a propensity to
    commit the crime, it must be excluded.”).
    Second, with respect to the District Court’s Allen
    charge, we reiterate that the Third Circuit Model Criminal
    Jury Instructions are not binding on district courts. While it
    may often be helpful to use the Model Instructions rather than
    fashioning one’s own, we are not prepared to say that, simply
    because an instruction differs from the model, that instruction
    must be erroneous. If, on the other hand, an instruction
    “stress[es] the time, expense or burden of a new trial,” the
    instruction would be unduly coercive and would require us to
    vacate a conviction and remand for rehearing. United States
    v. Jackson, 
    443 F.3d 293
    , 298 (3d Cir. 2006). The instruction
    at issue here did not stress any of those things, and merely
    mentioning that a case will have to be retried before another
    jury does not constitute coercion. Nonetheless, a court must
    be careful when highlighting the need to dispose of cases and
    the burden involved in calling a new jury.
    15
    the Fifth Amendment right to silence, “it would be
    fundamentally unfair and a deprivation of due process to
    allow [an] arrested person’s silence to be used to impeach an
    explanation subsequently offered at trial.” 
    426 U.S. 610
    , 618
    (1976).     The Court therefore held that “the use for
    impeachment purposes of petitioners’ silence, at the time of
    arrest and after receiving Miranda warnings, violated the Due
    Process Clause of the Fourteenth Amendment.” 
    Id. at 619.
    Of course, the rights secured by Doyle apply in equal effect
    “to federal prosecutions under the Fifth Amendment.” United
    States v. Agee, 
    597 F.2d 350
    , 354 n.11 (3d Cir. 1979).
    Reiterating the basis for the Doyle rule, as it has now
    come to be called, the Supreme Court has noted that “silence
    [should] carry no penalty” because the primary purpose of
    Miranda warnings is to safeguard an arrested individual’s
    Fifth Amendment right to not speak to law enforcement
    authorities.10 Wainright v. Greenfield, 
    474 U.S. 284
    , 290
    (1986). When seeking to impeach a defendant’s credibility, a
    prosecutor thus violates the Fifth Amendment when he
    highlights the defendant’s post-arrest silence.11 Gov’t of the

    Silence is not always protected. A defendant’s pre-
    arrest silence is not saved from a prosecutor’s reaches for
    impeachment purposes because “no governmental action
    induce[s] [a] petitioner to remain silent before arrest.”
    Jenkins v. Anderson, 
    447 U.S. 231
    , 240 (1980).
    11
    In Raffel v. United States, 
    271 U.S. 494
    (1926),
    decided decades before Miranda and Doyle, the Supreme
    Court concluded that a defendant “may be examined for the
    purpose of impeaching his credibility” since the Fifth
    Amendment “immunity from giving testimony is one which
    the defendant may waive by offering himself as a witness.”
    
    16 V.I. v
    . Davis, 
    561 F.3d 159
    , 165 (3d Cir. 2009); Hassine v.
    Zimmerman, 
    160 F.3d 941
    , 947-49 (3d Cir. 1998).
    A defendant may, however, open himself up to
    questions about his post-arrest silence if he “testifies to an
    exculpatory version of events and claims to have told the
    police the same version upon arrest.” 
    Hassine, 160 F.3d at 948
    (quoting 
    Doyle, 426 U.S. at 619
    n.11) (internal quotation
    marks omitted). In that very limited circumstance, some
    inquiry is permitted to prevent a defendant from misleading a
    fact-finder about his claimed cooperation with law
    enforcement. But the foundation for such an inquiry is not
    easy to lay. We have explained that, to open himself up to
    questions about his silence, it is not enough for a defendant’s
    later testimony to be “ambiguous” about his supposed
    cooperation. 
    Id. at 948
    (quoting United States v. Fairchild,
    
    505 F.2d 1378
    , 1382 (5th Cir. 1975)). Instead, his earlier
    silence “must appear to be an act blatantly inconsistent with
    ... [his] trial testimony.” 
    Id. (quoting Fairchild,
    505 F.2d at
    1382) (internal quotation marks omitted).
    Even when the government wrongly cross-examines a
    defendant about his post-arrest silence, however, that does not
    mean that his conviction will necessarily be infirm. The error
    may still be harmless. The operative question becomes
    whether the “constitutional trial error was harmless beyond a
    reasonable doubt.” 
    Davis, 561 F.3d at 165

    v. California, 
    386 U.S. 18
    , 24 (1967)). To sustain a

    In light of later precedent, however, that
    conclusion clearly does not apply when a prosecutor
    explicitly questions a defendant’s post-Miranda silence.

    561 F.3d 159
    , 165 (3d Cir. 2009).

    conviction, the government must “prove beyond a reasonable
    doubt that the error complained of did not contribute to the
    verdict obtained.” 
    Chapman, 386 U.S. at 24
    . We have
    previously determined that error of the sort condemned in
    Doyle “may be held harmless beyond a reasonable doubt in
    cases where there is overwhelming evidence against the
    defendant.” 
    Davis, 561 F.3d at 165
    . But it is a “decidedly
    heavy burden ... to demonstrate that reversal is not
    warranted.” United States v. Waller, 
    654 F.3d 430
    , 438 (3d
    Cir. 2011).
    A.     Objection and Preservation for Appeal12
    As a threshold matter, we must first determine
    whether, under Rule 103(a)(1)(B) of the Federal Rules of
    Evidence,13 Shannon properly objected to the government’s
    cross-examination and preserved that objection so that we can
    exercise plenary review, or whether we must only review the
    alleged Doyle violation for plain error. We thus turn to the
    record.
    12
    We evaluate de novo a Fifth Amendment violation
    under Doyle v. Ohio, 
    426 U.S. 610
    (1976), unless the
    defendant failed to object at trial. Gov’t of the V.I. v.
    Martinez, 
    620 F.3d 321
    , 335 (3d Cir. 2010). In that case, we
    review only for plain error. United States v. Balter, 
    91 F.3d 427
    , 441 (3d Cir. 1996).
    13
    Rule 103 of the Federal Rules of Evidence provides
    that “[a] party may claim error in a ruling to admit or exclude
    evidence only if the error affects a substantial right of the
    party” and, if the evidence is admitted, the party objecting
    “states the specific ground [for the objection], unless it was
    apparent from the context.” Fed. R. Evid. 103(a).
    18
    From a plain reading of the trial transcript, it is clear
    that the government asked Shannon about his post-arrest
    silence. When Shannon’s counsel attempted to object, he was
    emphatically overruled:
    Q: Did you ever direct anyone to come to the
    authorities and say, listen, you need to know about
    [Williams]?
    [Defense counsel]: Your Honor, may we have a side-
    bar, please?
    THE COURT: No.
    [Defense counsel]: I object to that.
    THE COURT: Overruled, if that’s an objection.
    [Defense counsel]: It’s a comment.
    THE COURT: He’s asking the question. Did you ever
    tell anybody about Williams.
    (App. at 1474.) Upon being directed by the District Court to
    answer the government’s question, Shannon did answer, but
    his counsel continued objecting and was, again, overruled:
    A: I told my lawyer about Williams.
    Q: Did you ever direct anyone to bring that
    information to law enforcement?
    [Defense counsel]: Your Honor, it’s a Fifth
    Amendment comment. I object. I would like a
    side-bar.
    THE COURT: You’re overruled.
    A: No. No.
    Q: You waited until you took the stand and then
    you told us about [Simpson, Williams, and
    Middlebrooks]; right?
    19
    A. Yes, sir.
    [Defense counsel]: I renew my objection, Your
    Honor.
    (Id.)
    Defense counsel’s consternation was fully justified, as
    the questions the government asked Shannon are patently
    beyond the bounds set in Doyle. They are indeed textbook
    examples of a Fifth Amendment violation.
    Notwithstanding the obvious error that the
    government’s questioning created at trial, and despite the
    specific and repeated objections from Shannon’s attorney, the
    government now contends that the objections were
    “insufficient to alert the court of the right he was asserting
    because defense counsel did not even tell the court that
    Shannon had invoked Miranda.” (Gov’t’s Br. at 22.)
    Repeating that line of attack at oral argument, the government
    claimed that the Assistant United States Attorney (“AUSA”)
    who prosecuted the case did not understand Shannon’s
    objection “because frankly Doyle wasn’t mentioned,
    Miranda’s not mentioned.” (Oral Arg. at 23:48-56.) The
    government thus asks that we adopt a bright-line rule that
    would require defense counsel to explicitly cite Doyle or its
    progeny when objecting to the government’s questions about
    a defendant’s post-arrest silence, as one of our sister circuits
    has recommended.14 (See Gov’t’s Br. at 22 (“In Shannon’s
    14
    The United States Court of Appeals for the First
    Circuit in United States v. O’Brien stated that objecting
    counsel should either “point to Doyle or a counterpart case or
    ... articulate an objection that was in substance close to the
    20
    case, defense counsel never mentioned Doyle in the district
    court. ... This was insufficient to alert the court of the right he
    was asserting because defense counsel did not even tell the
    court that Shannon had invoked Miranda – much less inform
    it that his objection had anything to do with Miranda – until
    after the trial was over.”).) We decline that invitation.
    To begin with, the government’s claim that it did not
    understand the objection is belied by the record. Besides the
    fact that defense counsel explicitly stated the grounds for his
    objection as being based on the Fifth Amendment, the
    colloquy among the AUSA, defense counsel, and the District
    Court after the defense rested makes clear that the
    government understood the nature of Shannon’s objection.
    Before closing arguments, defense counsel asked that the
    District Court provide “a very intense cautionary instruction
    on the government comment on my client’s silence.” (App.
    at 1489.) When the Court replied that Shannon “waive[d]
    [his] Fifth Amendment rights when [he] t[ook] the witness
    stand,” defense counsel rightly corrected the Court and
    explained that taking the witness stand does not waive a
    defendant’s right to be free of questioning about his post-
    arrest silence. (Id.) While the government now pleads
    rationale of Doyle” to preserve the objection. O’Brien, 
    435 F.3d 36
    , 39 (1st Cir. 2006). What appears to have motivated
    the court in O’Brien, however, was the fact that defense
    counsel in that case gave “the wrong ground” for an
    objection. 
    Id. That is
    not the case here. Shannon’s counsel
    clearly objected and said, “Fifth Amendment comment.”
    (App. at 1475.)
    21
    ignorance, the AUSA arguing before the District Court
    apparently understood that defense counsel was objecting to
    the inquiry into post-arrest silence. In fact, the AUSA
    responded by stating that “[o]nce [the defendant] gets on the
    witness stand and presents his side of the story, he’s putting
    that out there and he waited a year to do that.” (Id. at 1489-
    90.) Although defense counsel continued disputing the
    propriety of the government’s inquiry into Shannon’s silence,
    the District Court declined to give any curative or cautionary
    instruction.
    Given that background, it beggars belief to hear the
    government now argue that the Fifth Amendment issue was
    not preserved for review. It was preserved, and the argument
    to the contrary actually borders on frivolous. We therefore
    will review the issue de novo and not, as the government
    requests, for plain error. Gov’t of the V.I. v. Martinez, 
    620 F.3d 321
    , 335 (3d Cir. 2010).
    B.     Opening the Door
    The government next argues that, even if the objection
    was preserved for plenary review, the AUSA’s questions
    were appropriate and did not constitute a Doyle violation
    because Shannon “opened the door by implying he had
    cooperated in an investigation to find [Williams]” and
    because “most of the prosecutor’s questions probed
    Shannon’s pre-arrest failure to call police when [he] realized
    Middlebrooks handed him dope’ or drug-money.” 15 (Gov’t’s
    15
    We focus our analysis on those questions the
    government asked Shannon during cross-examination. The
    government notes that the “AUSA said nothing about
    22
    Br. at 20-21.) The government points to Shannon testifying
    that he had “tried to ‘find [Williams,]” and it says he “twice
    implied that his efforts ... were undertaken in cooperation
    with authorities.” (Id. at 27 (citing App. at 1388, 1399).) If
    Shannon had not been working with authorities, the
    government asks, “why else [would he be] … trying to find
    [Williams]?” (Oral Arg. at 18:11-13.) The government
    contends that Shannon waived his Fifth Amendment rights as
    explained in Doyle because a “defendant who wishes to
    protect his post-arrest silence cannot ‘imply that he had
    participated actively in the investigation.’” (Gov’t’s Br. at 28
    (quoting 
    Hassine, 160 F.3d at 949
    ).)
    On this point, as on the earlier question of whether the
    Fifth Amendment issue was preserved by appropriate
    objection at trial, the government’s arguments strike us as
    badly strained. The record simply does not reveal any
    “opening of the door” to allow questioning about Shannon’s
    post-arrest silence. Here is the exchange the government
    relies on:
    Shannon’s silence in his [initial] closing argument” (Gov’t’s
    Br. at 29) until Shannon’s closing emphasized that the
    government did not “negate the legitimacy of [Shannon’s]
    story regarding why he went to Baltimore and that his
    nephew, like a son for him, ... wanted to get a phone.” (App.
    at 1607 (Appellant Closing Statement).) Even assuming that
    sequence forgave the comments at closing, it is irrelevant to
    the question of whether the government violated Shannon’s
    Fifth Amendment rights under Doyle during its cross-
    examination.
    23
    [AUSA]: Have you looked at those phone
    records?
    A: We looked at them. Me and my counsel went
    over the phone records. Keep in mind it was,
    what, eight, nine months had passed by. I
    looked at the phone records and tried, to the best
    of my knowledge, give the phone that I thought
    was [Williams’s].        They took the phone,
    investigated it. Several phones that people call
    me, the numbers was dislocated. Other phone
    numbers that they called people would know me,
    but didn’t know ... Williams. And when we
    finally got a phone number that I thought was
    his, it was actually a guy that works on cars,
    works at Meineke. Meineke Mufflers.
    Q: You looked at the phone records because you
    know [Williams’] number has to be on that;
    right?
    A: Yes. It has to be on there.
    Q: It has to be on the Verizon phone records?
    A: Yes, sir.
    Q: And so, you looked at them and you can’t find
    [Williams’] number?
    A: No, sir. I can’t remember his number because I
    didn’t have it locked in.
    Q: When you say you didn’t have it locked in,
    you didn’t have it saved in your contacts?
    A: Didn’t have it saved in my phone. Yes, sir.
    (App. at 1416-17.)
    24
    There is nothing in that exchange or elsewhere in the
    record that can reasonably be construed as Shannon waiving
    his Fifth Amendment rights. Shannon did not “trumpet[] his
    post-arrest cooperation,” as the government claims. (Gov’t’s
    Br. at 26.) On the contrary, he told the government only what
    he and his defense team undertook to corroborate his story.
    While the government asserts that Shannon’s reference to
    “they” is a reference to the government, the transcript cannot
    comfortably bear that interpretation. (Id. at 27-28.) Shannon
    appears to be referring to the defense team reviewing his
    phone usage, not to any investigation by the government.
    The government also claims that Shannon first
    intimated his cooperation when he prefaced an answer about
    Williams with the phrase “like I tell you earlier,” as if
    “earlier” meant pre-trial and referred to working with the
    government. (App. at 1400.) But in that portion of his
    testimony Shannon was plainly not referring to pre-trial
    communications with the government but to a statement in
    Court he had made only moments earlier that he had met
    Williams at a restaurant in Houston.16 It is frankly painful to
    watch the government’s labored wresting of selected
    sentences from Shannon’s testimony in an effort to create an
    impression which a straightforward reading of the record
    refutes. We are left to agree with Shannon that the
    government’s arguments are nothing more than a “post hoc
    attempt to salvage an unsalvageable mistake made by the trial
    prosecutor.” (Appellant’s Reply Br. at 14.)
    16
    Shannon testified, “I wouldn’t get in touch with him.
    I would if, like I tell you earlier, I would see him at the place
    called the Boiling Crab on different occasions.” (App. at
    1400.)
    25
    We have searched the record in vain for evidence that
    Shannon’s silence was “blatantly inconsistent with [his] trial
    testimony,” as required by Hassine to render permissible the
    kinds of questions the government 
    asked. 160 F.3d at 948-49
    (citation omitted) (internal quotation marks omitted). The
    government argues that the “blatant inconsistency ... is that
    [Shannon] says he’s trying to find [Williams, telling several
    people his version of the story], but then he doesn’t convey
    information to those people which would enable them to help
    him or do anything.” (Oral Arg. at 18:51-19:09.) But that
    argument shows that government’s counsel still does not
    appreciate the import of Doyle. The government should
    know that Shannon does not need to “convey” information to
    anyone; beyond question, he has no responsibility to prove
    his innocence. And it should also recognize that there was
    nothing in Shannon’s testimony that was “blatantly
    inconsistent” with his post-arrest silence. The government
    conceded as much at oral argument when it characterized as
    “vague” Shannon’s responses regarding who he might have
    been working with to find Williams. (Oral Arg. at 20:01-03.)
    “Vague” obviously does not reach the high threshold of
    “blatantly inconsistent.” If Doyle means anything, it is what
    is said in its very first paragraph: that it is a violation of a
    defendant’s due process rights for a “prosecutor ... to impeach
    a defendant’s exculpatory story, told for the first time at trial,
    by cross-examining the defendant about his failure to have
    told the story after receiving Miranda warnings at the time of
    his arrest.” 
    Doyle, 426 U.S. at 611
    (footnote omitted). That
    is precisely what happened here.
    The government’s second argument – that “most of the
    prosecutor’s questions probed Shannon’s pre-arrest failure to
    26
    call police” – is also a stretch of the record. (Gov’t’s Br. at
    21.) Very few questions in that cross-examination addressed
    Shannon’s pre-arrest failure:
    Q: When you see it’s money, you panic?
    A: Yes, sir.
    Q: You don’t call the police; do you?
    A: No, sir. I don’t call the police.
    Q: You instead think, I'm going to get out of my
    car, maybe I’ll call Quita?
    A: Yes, sir.
    (App. at 1448.) The government’s questions about post-arrest
    silence were also limited, consisting of the following: (1)
    “Did you ever direct anyone to come to the authorities and
    say, listen, you need to know about ... Williams?”; and (2)
    “You waited until you took the stand and then you told us
    about [Simpson, Williams, and Middlebrooks]; right?” (App.
    at 1475.) The government’s implication that the questioning
    about Shannon’s silence was largely innocuous because it
    focused on Shannon’s pre-arrest silence does not accord with
    the reality that both pre-arrest and post-arrest silence received
    roughly the same degree of inquiry. More to the point, the
    number of questions the government asked is not relevant to
    the inquiry before us. Even if the government had, in fact,
    asked pages of questions regarding Shannon’s pre-arrest
    silence, the problem remains that it also asked inappropriate
    questions regarding Shannon’s post-arrest silence. Doyle
    does not establish a threshold quantity of improper
    questioning to qualify as a constitutional violation. Here, the
    two questions asked by the government regarding Shannon’s
    post-arrest silence violated his Fifth Amendment right to
    silence, as explained in Doyle.
    27
    C.     Harmless Error Analysis
    Our analysis, however, does not end with the finding
    of a constitutional error at trial. We must still determine
    whether the government proved beyond a reasonable doubt
    that the error did not contribute to the verdict obtained.17
    
    Chapman, 386 U.S. at 24
    . When the government fails to
    carry its burden of proof, we must vacate the judgment of
    conviction and remand for a new trial. That is the result
    required here.
    Viewed in its totality, the evidence against Shannon
    was largely circumstantial and not “overwhelming,” as
    required by 
    Davis.18 561 F.3d at 165
    . “The government
    17
    The government argues that Brecht v. Abrahamson,
    
    507 U.S. 619
    (1993), is instructive, but, as the government
    itself notes, “Brecht was decided on collateral rather than
    direct review” (Gov’t’s Br. at 32 (citing 
    Brecht, 507 U.S. at 637-38
    (holding that constitutional error is harmful under
    collateral review when that error “had substantial and
    injurious effect or influence in determining the jury’s
    verdict”))), and consequently is irrelevant to our analysis.
    18
    We are not implying, of course, that the evidence
    against him was insignificant. It certainly was not. The
    government presented the following persuasive evidence at
    trial: Shannon’s Boost Mobile phone chirped in Eighty Four
    virtually every time Middlebrooks visited Pittsburgh.
    Shannon was entrusted with $669,340 to hold for the
    conspiracy, despite, according to him, being a complete
    stranger to that conspiracy. And Shannon falsified his
    logbooks, a violation of federal law in its own right, to hide
    28
    conducted months of investigation, listened to thousands of
    hours of wiretaps, [and] yet had not once heard of Shannon.”
    (Appellant’s Opening Br. at 26.) Not one government record
    revealed a call, text, or even an email between Shannon and
    anybody else involved in the conspiracy. Without more in the
    way of corroborating evidence linking Shannon to the
    conspiracy, the jury’s assessment of Shannon’s credibility
    was likely important to the outcome of the case.19 Because
    that credibility was undermined by the government’s
    questioning of Shannon about why he had not come forward
    earlier to the police, we cannot say the constitutional error
    was harmless. Chapman mandates that the government must
    “prove beyond a reasonable doubt that the error complained
    of did not contribute to the verdict 
    obtained,” 386 U.S. at 24
    ,
    but the government has not done so, and the verdict cannot
    stand.
    frequent trips, that, perhaps by sheer coincidence, had him
    driving through Eighty Four on multiple occasions. Although
    such evidence may well be sufficient to convict, it is not
    enough to sustain a conviction when, as in this case, there has
    been a Fifth Amendment violation and the case depends so
    heavily on whether one believes the defendant’s story.
    19
    In the past, we have found “harmless error” in
    limited circumstances where the government presented
    additional corroborating evidence at trial. See 
    Davis, 561 F.3d at 166
    . In United States v. Balter, 
    91 F.3d 427
    , 431 (3d
    Cir. 1996), for example, the government offered taped
    conversations substantiating its theory of the case. Similarly,
    in United States v. Dunbar, 
    767 F.2d 72
    , 73 (3d Cir. 1985),
    two bank tellers separately identified the defendant after a
    surveillance camera captured pictures of him robbing a bank.
    Here, the government has offered no such evidence.
    29
    III.   CONCLUSION
    For the foregoing reasons, we will vacate the District
    Court’s judgment and remand for a new trial consistent with
    this opinion.
    30
