    ARGUED MAY 23, 2019 — DECIDED SEPTEMBER 3, 2019

    Before BAUER, MANION, and BRENNAN, Circuit Judges.
    BRENNAN, Circuit Judge. Digital platforms unleash instant
    and limitless capabilities; at the tap of a finger, one can touch
    the world. That power and freedom enables many noble
    pursuits. But, as this case shows, underneath the promise of
    modern connectivity can lurk a dark side.
    Over a seven‐week span, Mohammad Khan used Face‐
    book and his job as an Uber driver to threaten and prepare for
    2                                                   No. 18‐2612
    mass murder. He posted messages threatening to “kill,”
    “shoot,” “hunt,” “murder,” and “put bullets in” his “targets.”
    Khan’s “targets” included “college student[s],” “vulnerable
    individuals,” people “walking their dogs,” “high net worth
    individual[s],” and “witnesses” that “get [in] the way.” He
    aimed for “a real human tragedy” and “claim[ed] the loop
    area of Chicago to the Northern Lincoln Park area” as his
    “free kill zone.” Worse, Khan planned to “purchase a
    [G]o[P]ro camera, strap it to [his] chest or forehead, record the
    killings, and upload them onto Facebook for everyone around
    the world to see the grisly footage of death.”
    Khan also drove for Uber. He posted messages about “dry
    run[s]” and carrying a loaded gun during shifts to prepare for
    “necessary murders”—in fact, several of his threatening posts
    occurred immediately before and after driving passengers. To
    add credence to his threats, Khan boasted his “mental forti‐
    tude to pull it off,” posted photos of himself holding the guns
    he would use, and “sw[ore] to Allah and everything I hold
    dear that I will resort to murder in the next 30 days.” That
    thirty‐day deadline corresponded with the date Khan was to
    fly to Pakistan.
    Khan used Facebook to draw the public into his world; in‐
    stead he drew the attention of the FBI. His words and actions
    resulted in an indictment for making interstate threats to in‐
    jure others, a violation of 18 U.S.C. § 875(c). At trial, Khan
    claimed his statements were not “true threats.” A jury disa‐
    greed and convicted him.
    Khan challenges his conviction, arguing that the govern‐
    ment’s indictment and evidence against him were insuffi‐
    cient. He also challenges the jury instructions for the § 875(c)
    charge and the district court’s refusal to suppress all evidence
    No. 18‐2612                                                    3
    leading to his arrest. Neither challenge is persuasive, so we
    affirm.
    I
    What prompted Khan’s graphic posts? Three sources
    stand out. First, a pedestrian sued Khan and Uber after a traf‐
    fic accident. Khan construed the lawsuit and related insur‐
    ance claims process as “senseless provocations.” Second, he
    believed “noise pollution around [his] house” to be “orga‐
    nized persecution,” for which he promised murder in retalia‐
    tion. Third, for unstated reasons, he believed Chicago Mayor
    Rahm Emanuel “doomed Chicago to an early grave.” For that,
    Khan called Emanuel a “rabid dog” who “shall be taught a
    lesson [he] will not forget.”
    The Facebook posts at issue began in late March 2015 and
    ended about two months later with Khan’s arrest. These in‐
    cluded:
       April 5: “[I]f there are any more senseless provoca‐
    tions committed against me or my family, I will
    purchase a [G]o[P]ro camera, strap it to my chest or
    forehead, record the killings, and upload them onto
    Facebook for everyone around the world to see the
    grisly footage of death with their own eyes.”
       April 9: “If these provocations do not cease right
    away I will head out to Chicago with my fourth
    generation Glock 19 and start hunting. I’m claiming
    the loop area of Chicago to the northern Lincoln
    Park area where the students be as free fire zones if
    push comes to shove. A free fire zone and a free kill
    4                                                        No. 18‐2612
    zone as well, because as I’ve stated in earlier con‐
    texts I will be aiming for the posterior part of the
    cranium.”
       April 14: “Keep pushing me and it won’t end well
    for a trucker on the road. I’ll pull out my glock and
    shoot him on the highway, causing a massive
    pileup with many potential fatalities. … Be care‐
    ful.”
       April 17: “I’ve given plenty of warnings … and this
    kind of stuff tends to happen suddenly. I’m already
    carrying my gun with me to work and let me be
    frank here I see a great deal of vulnerable individ‐
    uals, for example walking their dogs and whatnot.”
       May 2 (Post 1): “There will be blood running in the
    streets of Chicago as I had stated. In the next 30
    days, I will undertake the necessary murders. … I
    swear to Allah and everything I hold dear that I will
    resort to murder in the next 30 days.”
       May 2 (Post 2): “It’s not easy to kill. It takes mental
    fortitude to pull it off. I take this as a personal chal‐
    lenge … I’m gona try to empty out as much of the
    clip on the victim in a 5 second window as possi‐
    ble.”
       May 3: “The … deadline I have set is not written in
    stone. If I see vulnerabilities, any at all, I will exploit
    them immediately. Murder is in the air on the
    streets of Chicago. I can’t control my 9 [millime‐
    ter].”

       May 7 (Post 1): “Tonight is promising to be a mur‐
    derous night!”
       May 7 (Post 2): “Alrighttt … I’m goin hunting tonite
    baby!”
       May 7 (Post 3): “If I see a high value target Ima ex‐
    ploit it. I’m not killin sum bum on the street. I want
    a high net worth individual to shoot. I want this to
    be a real human tragedy. Much mourned. I have a
    month. Ima hunt aggressively tonight. Keep an eye
    out for ideal victims. If I don’t catch nobody tonite
    then another nite.”
       May 8: “Good dry run tonight. Saw a couple of ex‐
    cellent targets. The key is right approach and tim‐
    ing. There were many potential witnesses because
    it was a college student night. Inshallah1 the deed
    will be done well before the deadline I have set. …
    When I have said something, it means I will do it.
    The rest is opportune timing.”
       May 14: “The gun is cocked and ready to go. …
    Now I’m gona get my revenge, and that involves
    putting bullets in someone’s body, so get out of the
    way or I’ll literally shoot at them as well and we’ll
    end up with a much bigger scenario on our hands.
    I’m not leaving America without getting revenge
    even if it costs me my life. And that’s that.”

    willing.” Merriam‐Webster’s Online Dictionary, https://www.merriam‐
    webster.com/dictionary/inshallah (last visited September 3, 2019).
    6                                                 No. 18‐2612
    Khan sent the third May 7 post about hunting for “ideal
    victims” one minute before he picked up an Uber passenger.
    The May 8 post about a “dry run” was sent three minutes after
    he dropped off another Uber passenger. Khan’s Facebook
    page also included several photos of guns and ammunition
    he threatened to use, as well as photos of him holding those
    weapons.
    Law enforcement first learned of Khan’s Facebook posts
    about a week after they began. The Illinois State Police run a
    website that allows users to send anonymous complaints. Af‐
    ter police received an anonymous tip containing a link to
    Khan’s Facebook page, they immediately notified the FBI but
    did not forward or save the original tip itself. Because Khan
    set his Facebook privacy settings to “public,” anyone with ac‐
    cess to Facebook (including the FBI) could view his comments
    and photos.
    Khan sent the May 14 post, about getting revenge before
    leaving America, from his home. When he left his house later
    that day, surveilling FBI agents notified the DuPage County
    Sheriff’s Department that Khan drove off after threatening to
    kill people in his car and that he may be armed.
    At the FBI’s request, Sheriff’s Detective Patrick O’Neil
    found Khan about one block from his home, pulled him over,
    and asked him to step out of the car. When Khan opened the
    door, O’Neil saw the handle of a gun in the driver’s side door.
    On O’Neil’s order Khan walked to the rear of his car, where
    O’Neil told him that he was being “detained” for an FBI in‐
    vestigation. O’Neil then asked Khan if he was armed. Khan
    told O’Neil that a loaded gun was in the car and admitted he
    did not have a concealed carry license. O’Neil next asked for
    Khan’s permission to get the gun. Khan agreed. Once backup
    No. 18‐2612                                                   7
    arrived, O’Neil recovered a nine‐millimeter handgun—the
    same gun referenced and pictured in Khan’s Facebook posts.
    Sheriffs arrested Khan at the scene, and he was charged
    with violating Illinois’s concealed carry laws. After Khan’s ar‐
    rest, sheriffs performed a routine inventory search of his car
    where they found a loaded magazine under the passenger‐
    side front seat. That same day FBI agents obtained a warrant
    and searched Khan’s home. There, agents found two guns de‐
    picted in Khan’s Facebook photos—a .40 caliber semi‐auto‐
    matic handgun and a 12‐gauge semi‐automatic shotgun—and
    a box for the nine‐millimeter handgun, which contained three
    loaded magazines.
    A grand jury indicted Khan for violating 18 U.S.C.
    § 875(c), which makes it a crime to transmit in interstate com‐
    merce “any communication containing … any threat to injure
    the person of another.” The indictment charged Khan with
    maintaining “an account at Facebook in his own name” and
    that he “used the account to post messages and photographs
    that could be viewed on the internet by all Facebook users.”
    It also quoted the May 7 (Post 3), May 8, and May 14 posts,
    and described Khan’s purchase of a plane ticket to Karachi,
    Pakistan for travel on June 8, 2015.
    At trial, Khan denied his posts were threats. Instead, he
    said they were “[f]acetious,” “artistic,” “hyperbole,” and
    emulations of rap songs “protected by the First Amendment.”
    He also said he used Facebook like a “free notebook” that he
    believed no one would read. The jury rejected these defenses
    and found Khan guilty. The district court sentenced him to 41
    months’ imprisonment.

    II
    Khan challenges his conviction. He disputes his indict‐
    ment, the jury instructions, the evidentiary rulings at trial,
    and the sufficiency of the evidence. We address each argu‐
    ment in turn.
    A
    We review the sufficiency of an indictment de novo.
    United States v. Miller, 
    883 F.3d 998
    , 1002 (7th Cir. 2018). An
    indictment must: (1) state the elements of the offense charged;
    (2) fairly inform the defendant of the nature of the charge so
    that he may prepare a defense; and (3) enable the defendant
    to plead an acquittal or conviction as a bar against future pros‐
    ecutions for the same offense. 
    Id. (citations and
    internal quo‐
    tations omitted). The key question is whether the indictment
    sufficiently apprised Khan of the charges against him in order
    to enable adequate trial preparation. See United States v.
    Vaughn, 
    722 F.3d 918
    , 927 (7th Cir. 2013).
    Here, the indictment mirrored the terms of § 875(c), alleg‐
    ing Khan “transmit[ted] in interstate commerce a communi‐
    cation containing a threat to injure the person of another,
    namely, the [May 14, 2015] communication … [i]n violation of
    Title 18, United States Code, Section 875(c).” So far, so good;
    Khan does not dispute that the indictment apprised him of
    the governing statute. Instead, he argues the indictment failed
    to allege he intended to make threats when he made the Face‐
    book posts. Khan moved the district court to dismiss the in‐
    dictment on the same grounds. The court denied his motion
    and characterized his objections as “a defense relating to the
    strength of the government’s evidence [which] ordinarily
    must wait for trial.”
    No. 18‐2612                                                     9
    Although § 875(c) omits any mention of criminal intent,
    the statute still “include[s] broadly applicable scienter re‐
    quirements.” Elonis v. United States, 
    135 S. Ct. 2001
    , 2009 (2015)
    (“The fact that the statute does not specify any required men‐
    tal state … does not mean that none exists.”). “[T]he mental
    state requirement in Section 875(c) is satisfied if the defendant
    transmits a communication for the purpose of issuing a threat,
    or with knowledge that the communication will be viewed as
    a threat.” 
    Id. at 2012.
        This indictment did not explicitly accuse Khan of intend‐
    ing to send a threat, or allege that he knew the posts would be
    viewed as threats. But an indictment need not “spell out each
    element” as long as “each element [is] present in context.”
    United States v. Smith, 
    223 F.3d 554
    , 571 (7th Cir. 2000). An im‐
    plicit allegation of an element of a crime is enough; the indict‐
    ment “need not specifically allege” every “component part of
    the offense.” United States v. Resendiz‐Ponce, 
    549 U.S. 102
    ,
    107‐08, 108 n.4 (2007).
    On its face, the indictment charged Khan with transmit‐
    ting threats to “get my revenge,” “hunt aggressively,” “ex‐
    ploit,” and “kill” “ideal victims.” Those words denote
    purpose, knowledge, and intent. See 
    Smith, 223 F.3d at 572
    (re‐
    jecting challenge to language of indictment and holding “pur‐
    pose, knowledge, and intent are inherent” in the words
    “induce” and “entice”). The indictment, reasonably inter‐
    preted and given the full context of its allegations, alleged
    Khan’s intent.
    Next, Khan argues the indictment failed to set forth who
    he threatened, as well as where, when, why, and how threat‐
    ened violence would occur. The omission of these facts, he
    claims, rendered the indictment impermissibly “vague and
    10                                                  No. 18‐2612
    nonspecific.” Khan asks too much of the indictment. We re‐
    view indictments “on a practical basis and in their entirety,”
    not in a “hypertechnical manner.” 
    Miller, 883 F.3d at 1002
    .
    “Although the indictment must provide some means of pin‐
    ning down the specific conduct at issue[,] … the presence or
    absence of any particular fact need not be dispositive.” United
    States v. Sandoval, 
    347 F.3d 627
    , 633 (7th Cir. 2003).
    Regardless, this indictment provides the facts Khan claims
    are missing. It cites three specific threats, gives the itinerary
    of Khan’s flight to Pakistan, and states that the operative facts
    were based on his Facebook “messages and photographs” ac‐
    cessible to “all Facebook users.” That was enough to signal:
    what (threats of mass murder); who (at least six specified “tar‐
    gets”); where (the Chicago loop to the Northern Lincoln Park
    area); how (a nine‐millimeter handgun, a .40 caliber semi‐au‐
    tomatic handgun, and a 12‐gauge semi‐automatic shotgun);
    why (Khan felt “provoked” by a lawsuit and noise pollution);
    and when (before he jumped on a plane to Karachi).
    The indictment satisfied all necessary criteria and amply
    apprised Khan of the charges against him. The district court
    did not err in refusing to dismiss it.
    B
    Khan next argues the district court failed to instruct the
    jury on all elements of a § 875(c) offense.
    We review this challenge in two steps. First, we review de
    novo “whether [the] jury instructions accurately summarize
    the law, but give the district court substantial discretion to
    formulate the instructions provided that the instructions rep‐
    resent a complete and correct statement of the law.” United
    States v. Bonin, No. 18‐1479, 
    2019 WL 3369562
    , at *8 (7th Cir.
    No. 18‐2612                                                    11
    July 26, 2019). “If the instructions are legally accurate, then we
    review the district court’s phrasing of the instructions for
    abuse of discretion.” 
    Id. Here, the
    instruction read:
    The indictment charges the defendant with
    transmitting, in interstate commerce, a threat to
    injure another person. In order for you to find
    the defendant guilty of this charge, the govern‐
    ment must prove each of the three following el‐
    ements beyond a reasonable doubt:
    1. The defendant knowingly transmitted in
    interstate commerce the communication
    charged in the indictment, on or about
    May 14, 2015; and
    2. This communication contained a true
    threat to injure the person of another; and
    3. The defendant intended it to communi‐
    cate a true threat or knew that the com‐
    munication would be viewed as a true
    threat.
    The jury instructions also said “[a] person acts knowingly
    if he realizes what he is doing and is aware of the nature of
    his conduct, and does not act through ignorance, mistake, or
    accident.” As for a “true threat,” the district court instructed
    the jury:
    A true threat is a serious expression of intent to
    commit unlawful physical violence against an‐
    other person or a group of people. The commu‐
    nication must be one that a reasonable observer,
    considering the context and circumstances of
    12                                                   No. 18‐2612
    the statement, including surrounding commu‐
    nications, would interpret as a true threat.
    The government does not have to prove that the
    defendant actually intended to carry out the
    threat, or even that the defendant had the capac‐
    ity to do so. A threat does not need to be com‐
    municated directly to its intended victim, or
    specify a particular victim, or specify when it
    will be carried out.
    A communication is not a true threat if it is
    merely idle or careless talk, exaggeration, or
    something said in a joking manner.
    The instructions the district court gave the jury accurately
    and thoroughly summarized applicable law. According to
    Elonis, the Supreme Court’s most recent decision on true
    threats, a conviction under § 875(c) requires: (1) the knowing
    transmission in interstate commerce of a communication; (2)
    the communication contained a threat; and (3) the communi‐
    cation was transmitted for the purpose of issuing a threat, or
    with knowledge that the communication would be viewed as
    a threat. 
    Elonis, 135 S. Ct. at 2008
    –12. A “true threat” is “a se‐
    rious expression of an intent to commit an act of unlawful vi‐
    olence to a particular individual or group of individuals.”
    United States v. Parr, 
    545 F.3d 491
    , 497 (7th Cir. 2008) (quoting
    Virginia v. Black, 
    538 U.S. 343
    , 359 (2003)). And “[a]true threat
    does not require that the speaker intend to carry it out, or even
    that she have the capacity to do so.” United States v. Dutcher,
    
    851 F.3d 757
    , 761 (7th Cir. 2017) (citations omitted). These
    holdings are reflected almost verbatim in the instructions
    Khan challenges. Khan fails to show an abuse of discretion.
    No. 18‐2612                                                    13
    Khan also argues the holdings of Brandenburg v. Ohio, 
    395 U.S. 444
    , 447 (1969), and 
    Black, 538 U.S. at 359
    –60, require the
    district court to instruct the jury on three more elements: that
    Khan intended to communicate a threat; that the intended vic‐
    tim received it; and that it caused the victim to feel threatened.
    Khan’s request here is incorrect for three reasons. One, a
    true threat does not need to be communicated directly to the
    intended victim. 
    Parr, 545 F.3d at 497
    . Two, Khan seeks a re‐
    dundant instruction about his intent, as the elements instruc‐
    tion already included a scienter component when it required
    proof that Khan “knowingly transmitted” his posts. In es‐
    sence, Khan demands an instruction requiring the govern‐
    ment to prove that he intended to do what he knowingly did
    do: send Facebook posts accessible to all Facebook users
    around the world. At trial, Khan testified he considered his
    Facebook account a private diary, so he lacked intent to con‐
    vey a threat or knowledge that his posts would be viewed as
    threats. Because he had only one “Facebook friend,” he said
    he believed no one would see his messages. Using a social me‐
    dia platform to publish one’s thoughts publicly on the Inter‐
    net is an odd way to keep a “private” diary. Yet however
    flimsy this argument appears, it was the jury’s province to
    weigh Khan’s credibility and decide whether those posts
    qualified as true threats. See 
    id. It did
    so and found Khan
    guilty.
    Last, neither Brandenburg nor Black require proof that a vic‐
    tim felt threatened, as Khan insists. Brandenburg says that
    speech “directed to inciting or producing imminent lawless
    action” and “likely to incite or produce such action” falls out‐
    side the protection of the First 
    Amendment. 395 U.S. at 447
    .
    Black held “a threat to a person or group of persons with the
    14                                                   No. 18‐2612
    intent of placing the victim in fear of bodily harm or death,”
    is likewise 
    unprotected. 538 U.S. at 359
    –60 (defining “[i]ntim‐
    idation” as a type of “constitutionally proscribable” speech).
    Khan posted increasingly aggressive promises to “murder” at
    least six specified “target” groups in a defined area of Chicago
    “well before” his dwindling deadline. These threats evince
    the type of intimidation and criminal action proscribed in
    Brandenburg and Black. And even if no one feared imminent
    action, nothing in Brandenburg, Black, or Elonis excludes the
    possibility of an unreported true threat. See 
    Dutcher, 851 F.3d at 762
    (rejecting contention that unreported Facebook post
    threatening to assassinate the president was not taken seri‐
    ously). At any rate, an anonymous person viewed Khan’s
    posts and took them seriously enough to pass them on to the
    Illinois State Police.
    We find no error in the district court’s jury instructions.
    C
    Up next are Khan’s evidentiary challenges: the admissibil‐
    ity of the gun found in Khan’s car, and the anonymous tip
    forwarded to the FBI. Khan argues the district court should
    have suppressed this evidence. When reviewing the denial of
    a motion to suppress, we review the district court’s factual
    findings for clear error and issues of law de novo. United
    States v. Key, 
    889 F.3d 910
    , 912 (7th Cir. 2018).
    1
    We begin with the gun. Before trial, Khan moved to sup‐
    press the firearm seized from his car under two theories: the
    stop was not supported by reasonable suspicion, and he was
    entitled to Miranda warnings before being asked about a gun
    in the car. The district court denied Khan’s motion, finding
    No. 18‐2612                                                    15
    reasonable suspicion for the stop. The court also found that,
    when asked about guns, Khan was not in custody for Miranda
    purposes. Khan reprises his arguments on appeal.
    A traffic stop is lawful under the Fourth Amendment
    when a law enforcement officer has a particularized and
    objective basis for suspecting the person stopped of criminal
    activity. United States v. Yancey, 
    928 F.3d 627
    , 630 (7th Cir.
    2019) (citations and internal quotation marks omitted).
    “When more than one police officer is involved in the reason‐
    able‐suspicion analysis, courts consider their collective
    knowledge.” United States v. Street, 
    917 F.3d 586
    , 596 (7th Cir.
    2019). The collective knowledge doctrine permits a stop at the
    direction of, or based on information relayed from, another
    law enforcement agency. See United States v. Hensley, 
    469 U.S. 221
    , 232–33 (1985); see also 
    Street, 917 F.3d at 596
    . The doctrine
    applies even if the officer performing the stop does not have
    firsthand knowledge of information creating the justification
    for a stop. 
    Street, 917 F.3d at 596
    . Nor does it matter that the
    communication is by dispatch or a “wanted” bulletin, rather
    than face‐to‐face. 
    Hensley, 469 U.S. at 232
    ; Torry v. City of
    Chicago, No. 18‐1935, 
    2019 WL 3521146
    , at *5 (7th Cir. Aug. 2,
    2019). But this doctrine is not an end around Terry v. Ohio—
    the officer or agency relaying the information must have rea‐
    sonable suspicion to justify the stop. See Hensley, 
    469 U.S. 232
    ‐33. Reasonable suspicion exists when an officer can point
    to “specific and articulable facts which, taken together with
    rational inferences from those facts, reasonably warrant that
    intrusion.” United States v. Richmond, 
    924 F.3d 404
    , 411 (7th
    Cir. 2019) (quoting Terry v. Ohio, 
    392 U.S. 1
    , 21 (1968)).
    We apply a three‐pronged test to decide if collective
    knowledge exists: (1) “the officer taking the action must act in
    16                                                  No. 18‐2612
    objective reliance on the information received”; (2) “the of‐
    ficer providing the information—or the agency for which he
    works—must have facts supporting the level of suspicion re‐
    quired”; and (3) “the stop must be no more intrusive than
    would have been permissible for the officer requesting it.”
    
    Street, 917 F.3d at 596
    –97 (citations and internal quotation
    marks omitted). In evaluating these elements, we consider all
    information known to officers at the time of the stop and give
    due weight to the trial court’s assessment of the officers’ cred‐
    ibility and the reasonableness of their inferences. 
    Richmond, 924 F.3d at 410
    , 413.
    All three elements were met here. At the suppression hear‐
    ing, the district court heard testimony from O’Neil and the
    FBI agents who monitored Khan’s Facebook page, surveilled
    his residence, and relayed his threats to state police. O’Neil
    testified he relied on the FBI agents’ direction when he
    stopped Khan. The FBI agents gave specific reasons to stop
    Khan. They explained how Khan’s Facebook posts crescen‐
    doed in hostility, flaunted “dry runs” during work, repeated
    an impending deadline, and climaxed in his final threat to kill.
    The agents also relied on several days of surveillance and in‐
    terviews of individuals with personal knowledge of Khan.
    They gleaned even more information from public and law en‐
    forcement databases that corroborated aspects of his posts, in‐
    cluding his job with Uber, his ownership of guns, and his
    plans to leave the country. These circumstances taken to‐
    gether gave the FBI reasonable suspicion to suspect Khan in‐
    tended to commit a violent crime while driving. Finally, the
    stop was no more intrusive than the one the FBI could have
    conducted themselves. The district court appropriately im‐
    puted the FBI’s knowledge and reasonable suspicion to
    O’Neil. Objectively, the stop was justified.
    No. 18‐2612                                                    17
    But Khan contends the stop, even if justified, amounted to
    a custodial arrest, requiring Miranda warnings before any
    question about weapons. See, e.g., United States v. Higgins‐
    Vogt, 
    911 F.3d 814
    , 820 (7th Cir. 2018) (“Miranda warnings
    must be provided at the outset of any custodial interrogation
    by law enforcement.”). Setting to the side the legality of
    O’Neil’s question to Khan about guns, we consider whether
    Khan was in police custody or under arrest when asked.
    “[T]he temporary and relatively nonthreatening detention
    involved in a traffic stop or Terry stop does not constitute Mi‐
    randa custody.” Maryland v. Shatzer, 
    559 U.S. 98
    , 113 (2010) (ci‐
    tations omitted). Still, like any Terry stop, a traffic stop must
    be reasonably related in scope to the circumstances which jus‐
    tified the stop in the first place. Hiibel v. Sixth Judicial Dist.
    Court of Nev., Humboldt Cty., 
    542 U.S. 177
    , 185 (2004). It also
    “cannot continue for an excessive period of time or resemble
    a traditional arrest.” 
    Id. at 185–86
    (citation omitted). Khan
    highlights two parts of O’Neil’s testimony: that O’Neil did not
    know how long the stop would last, or where the questioning
    of Khan would occur. This uncertainty and potential for an
    indefinite detention, Khan claims, converted the stop into a
    custodial arrest.
    Khan’s argument misses the mark. We do not evaluate the
    abstract chance of an excessive detention. What matters is
    “whether law enforcement has detained the person longer than
    needed to carry out the investigation that was justified by the
    reasonable suspicion.” United States v. Lopez, 
    907 F.3d 472
    , 486
    (7th Cir. 2018) (emphasis added). Khan ignores this question
    altogether and submits no evidence showing that he was sub‐
    jected to a stop more excessive in duration, scope, or degree
    of intrusion than that needed to carry out the reason for the
    18                                                 No. 18‐2612
    stop—an investigation triggered by his online threats to shoot
    people from his car. Finding no evidence of an excessive stop
    in the record ourselves, we see no error in the district court’s
    conclusion that Khan was not in custody or under arrest when
    O’Neil asked him about guns. With that issue resolved, we
    turn to O’Neil’s question.
    The public safety exception to Miranda allows police offic‐
    ers to question a suspect without first giving Miranda warn‐
    ings if they reasonably believe the questions are “necessary to
    secure their own safety or the safety of the public.” New York
    v. Quarles, 
    467 U.S. 649
    , 655–57, 659 (1984); see also United
    States v. Hernandez, 
    751 F.3d 538
    , 540 (7th Cir. 2014) (holding
    same). O’Neil’s question fits within this exception. At the sup‐
    pression hearing, O’Neil testified he asked Khan about a gun
    in his car for “officer safety” and to dispel his suspicion that
    Khan had other guns with him. [R. 145, p. 227, 335.] O’Neil
    had reason to be concerned: he saw a gun in Khan’s driver’s
    side door. O’Neil was not required to ignore the gun, 
    Quarles, 467 U.S. at 657
    (holding a gun left unattended was a public
    safety concern); grab the gun, 
    Hernandez, 751 F.3d at 542
    (rec‐
    ognizing the risk of grabbing and setting off a loaded gun); or
    allow Khan to bolt for the gun, 
    Richmond, 924 F.3d at 417
    (rec‐
    ognizing the risk of a gun within a few steps from a suspect).
    Accordingly, O’Neil’s question if Khan was armed fell within
    the public safety exception to Miranda. Khan’s responses to
    that question, which included giving O’Neil permission to get
    the gun, pose no admissibility problems.
    The district court properly denied Khan’s motion to sup‐
    press the gun evidence.
    No. 18‐2612                                                      19

    Khan also sought to suppress all evidence against him be‐
    cause the government could not produce a copy of the anon‐
    ymous tip sent to Illinois State Police. The district court
    denied this request, finding the tip immaterial to the govern‐
    ment’s investigation and no bad faith by the government.
    At trial, Michael Forsythe, an administrative assistant for
    the state police, testified he received the tip via the state police
    website. After reviewing the tip, Forsythe sent an email to the
    FBI with a link to Khan’s Facebook profile. Critically, state po‐
    lice cannot trace the tip’s source, nor do they retain a copy of
    the tip (consistent with their email retention policies). They
    did, however, preserve evidence of Forsythe’s email to the FBI
    in an “Internet Activity Report.” Khan received a copy of this
    report in preparation for trial. On appeal, Khan contends the
    district court abused its discretion when it allowed testimony
    about “destroyed” evidence.
    To be sure, the government has an affirmative duty to pre‐
    serve and disclose material evidence favorable to a defendant.
    Arizona v. Youngblood, 
    488 U.S. 51
    , 55, 57–58 (1988). The gov‐
    ernment violates that obligation if, acting in bad faith, it fails
    to preserve potentially exculpatory evidence that a defendant
    would be unable to obtain by other means. Id.; see also United
    States v. Bell, 
    819 F.3d 310
    , 317–18 (7th Cir. 2016) (bad faith is
    “an official animus or a conscious effort to suppress exculpa‐
    tory evidence,” which “turns on an official’s subjective
    knowledge that the evidence in question had exculpatory
    value at the time it was lost or destroyed”). But according to
    Forsythe’s testimony, the anonymous tip was neither excul‐
    patory nor substantively material. Indeed, the government
    20                                                No. 18‐2612
    took on a credibility risk by discussing evidence it never pro‐
    duced. Over the government’s objection, the district court al‐
    lowed Khan to argue to the jury that the tip was intentionally
    destroyed. Khan also had all relevant information about the
    tip: the date, time, how it was sent, who received and re‐
    viewed it, and its substantive content. And Khan cross‐exam‐
    ined the government’s witnesses on all this information. The
    district court did not abuse its discretion when it found the
    government’s failure to produce a copy of the tip was imma‐
    terial.
    D
    Finally, we address Khan’s assertion he was convicted on
    insufficient evidence. His challenges face a high hurdle: we
    afford “great deference” to a jury verdict of conviction, view
    the evidence in the light most favorable to the government,
    and draw all reasonable inferences in the government’s favor.
    United States v. Moreno, 
    922 F.3d 787
    , 793 (7th Cir. 2019). We
    will reverse a conviction only where the record is devoid of
    evidence from which a reasonable jury could find guilt be‐
    yond a reasonable doubt. United States v. Heon Seok Lee, No.
    18‐1687, 
    2019 WL 3940951
    , at *6 (7th Cir. Aug. 21, 2019).
    Khan first asserts the government failed to prove “the tar‐
    get of the alleged threat[s].” Not so: Khan in fact called his
    potential victims “targets,” which included college students,
    people walking their dogs, truckers, and anyone else who
    happened to be in the wrong place (Khan’s defined “free kill
    zone”) at the wrong time (before his June 8, 2015 flight to
    Pakistan). The recipients of Khan’s threats are quite clear.
    Khan also claims the government failed to prove his Face‐
    book posts were true threats or that he intended to convey
    No. 18‐2612                                                   21
    those threats to anyone else. Before the Supreme Court’s de‐
    cision in 
    Black, 538 U.S. at 358
    –59, we used an objective rea‐
    sonable person standard to determine whether speech
    constituted a true threat. See Maier v. Smith, 
    912 F.3d 1064
    ,
    1072 (7th Cir. 2019) (citing 
    Parr, 545 F.3d at 499
    ). After Black,
    “we and other courts have wondered whether speech only
    qualifies as a true threat if the speaker subjectively intended
    his words to be threatening.” Id. (citing 
    Parr, 545 F.3d at 499
    ‐500). “[T]he Supreme Court has not definitively answered
    the question.” 
    Id. But we
    need not press this issue here. Khan’s
    posts were so violent, explicit, and resolute that they consti‐
    tuted threats under either an objective or subjective standard.
    Among other macabre warnings, Khan repeatedly and cate‐
    gorically threatened to murder defined targets in a defined
    area of Chicago and livestream “the grisly footage of death.”
    He also tied his threats to “revenge” for “provocations” and
    “persecutions” against him, connected the date of any at‐
    tempted murder to his flight out of the country, and bragged
    about his “mental fortitude to pull it off.” These personal ref‐
    erents undercut Khan’s defense that his words were artistic
    expressions. This is enough to reasonably infer Khan’s intent
    to commit an act of unlawful violence towards a particular
    group of individuals.
    Last, Khan contends the government offered no evidence
    that his threats would be seen. This also is not true: Khan’s
    posts were seen by at least one observer, who passed them on
    to police. After that, the FBI continued to monitor Khan’s pub‐
    lic threats in a forum accessible to over one billion Facebook
    users. The evidence amply supports Khan’s conviction.
    22                                                 No. 18‐2612
    III
    Boundless connection to the world can betray. Such was
    the case for Khan. We find no error in the district court’s rul‐
    ings, and AFFIRM Khan’s conviction.
