    Before WOOD, Chief Judge, and FLAUM and RIPPLE, Circuit
    Judges.
    FLAUM, Circuit Judge. One hundred police departments use
    a surveillance network of GPS-enabled acoustic sensors called
    ShotSpotter to identify gunfire, quickly triangulate its loca-
    tion, and then direct officers to it. As a matter of first impres-
    sion, this case requires us to consider whether law enforce-
    ment may constitutionally stop a vehicle because, among
    other articulable facts, it was emerging from the source of a
    2                                                     No. 19-2054
    ShotSpotter alert. The district court held that the totality of the
    circumstances provided the officer responding to the scene
    with reasonable suspicion of criminal activity to justify the
    stop. We affirm.
    I. Background
    ShotSpotter is a surveillance system that uses sophisti-
    cated microphones to record gunshots in a specific area. After
    a device detects the sound of gunfire, it relays the audio file
    to a server in California, where an individual determines
    whether the sound is a shot. When that individual confirms
    the sound is a gunshot, ShotSpotter sends it back to the local
    police department.
    In the very early morning of July 29, 2018, Travis Elle-
    fritz—an officer with the Peoria Police Department—was pa-
    trolling the city in his squad car. At 4:40:02 a.m., the Depart-
    ment’s ShotSpotter system reported two gunshots coming
    from 2203 North Ellis Street. When Officer Ellefritz received
    the ShotSpotter alert on his computer, he immediately started
    driving toward the 2200 block of North Ellis. On his way, Of-
    ficer Ellefritz heard the police dispatcher broadcast the
    ShotSpotter alert he had just received. He then heard the dis-
    patcher report a second ShotSpotter alert of three more shots
    fired.
    Additionally, the dispatcher stated: “Cars en route to Ellis.
    There are several cars leaving but seen going northbound on
    McClure.” The dispatcher also reported a “black male on foot
    who ran northbound on McClure.” As Officer Ellefritz ap-
    proached the location, he switched his car lights off, turning
    left from McClure Avenue onto North Ellis Street. He was the
    first officer at the scene. Shortly thereafter, Officer Ellefritz
    No. 19-2054                                                             3
    saw a car’s headlights down the road and noticed it was leav-
    ing North Ellis to come his way. This was the only vehicle Of-
    ficer Ellefritz observed on the street.
    Upon seeing the headlights, Officer Ellefritz activated his
    emergency lights and veered his vehicle into the lane of on-
    coming traffic. As the approaching car slowed, Officer Elle-
    fritz feared for a second that it was trying to get away from
    him, so he shouted “stop” as he exited his vehicle at 4:45:23
    a.m. Within seconds of this command, the car stopped next to
    the left bumper of Officer Ellefritz’s cruiser.1 The car’s occu-
    pants pointed backward, in the direction from where they
    came, yelling: “They are down there! They are down there!”
    Officer Ellefritz looked that way and observed a crowd of
    about 15–20 people at the street’s dead end, approximately
    300 feet from him.
    Officer Ellefritz kept his firearm drawn. He saw the de-
    fendant, Terrill Rickmon, in the passenger seat. The driver
    was the owner of the car. Both men kept their hands up until
    backup arrived. At that time, Rickmon informed the officers
    that someone had shot him in the leg. (Obviously, Officer Elle-
    fritz did not know Rickmon was wounded when Ellefritz orig-
    inally stopped the car.) With the driver’s consent, Officer Elle-
    fritz searched the automobile and found a nine-millimeter
    handgun under the passenger seat where Rickmon had been
    sitting.
    1The other car subsequently rolled back a few feet to a complete halt. Be-
    cause this occurred after Officer Ellefritz already commanded the stop, it
    does not factor into our analysis.
    4                                                                 No. 19-2054
    Because of his criminal history, a federal grand jury in-
    dicted Rickmon for possession of a firearm by a felon in vio-
    lation of 18 U.S.C. § 922(g)(1). Rickmon moved pro se to sup-
    press the firearm found by Officer Ellefritz, contending that
    the Peoria Police Department did not have records showing
    how many ShotSpotter reports were “false positive[s]” and
    that other systems in cities across the country were inaccurate
    and unreliable.
    On December 21, 2018, the district court presided over an
    evidentiary hearing regarding Rickmon’s motion to sup-
    press.2 Officer Ellefritz testified that, before the stop, he had
    2 At certain points in this case, Rickmon has somewhat taken issue with
    ShotSpotter’s reliability. A police department witness testified that, in
    general, SpotShotter validates whether a sound is a gunshot within sec-
    onds; however, in these specific circumstances, the witness was unable to
    say how long that process took. The district court also received evidence
    that SpotShotter is not always accurate and that officers may not solely
    rely on it to locate gunfire. As Rickmon points out, the record here does
    not demonstrate how often the Peoria Police Department received incor-
    rect ShotSpotter reports or anything else attesting to the reliability of the
    system. Still, the witness was subject to cross-examination about ShotSpot-
    ter’s reliability. See Florida v. Harris, 
    568 U.S. 237
    , 247 (2013) (observing that
    a defendant can challenge the reliability of certain evidence during cross-
    examination); United States v. Bonds, 
    922 F.3d 343
    , 345–46 (7th Cir. 2019)
    (similar). Rickmon, for his part, declined to further challenge ShotSpotter’s
    adequacy. Cf. 
    Harris, 568 U.S. at 248
    –49 (forfeiting similar argument). We
    therefore take his argument as based on reasonable suspicion and need
    not reach the reliability of ShotSpotter. In some future decision, we may
    have to determine ShotSpotter’s reliability where a single alert turns out
    to be the only articulable fact in the totality of the circumstances. See, e.g.,
    State v. Hill, 
    851 N.W.2d 670
    , 691 (Neb. 2014) (holding that ShotSpotter
    technology is reliable). But, in any event, this is not that case, given that
    911 calls corroborated the ShotSpotter reports here and Rickmon himself
    No. 19-2054                                                          5
    no idea how many people were in the car or who was in the
    car. Furthermore, he stated that he had no reason to suspect
    that any weapons used in the shooting were in this car. He
    explained that the occupants were not attempting to flee, they
    complied with his commands, and they neither moved suspi-
    ciously nor gestured threateningly. In sum, there was nothing
    particularly unusual about this car, except for the fact that it
    was leaving the area of the gunfire.
    Following the hearing, the district court denied Rickmon’s
    motion, ruling that the traffic stop was objectively reasonable
    based on the totality of the circumstances. The court reasoned:
    The short lapse of time between the dispatch
    and the stop, the 911 call of vehicles leaving the
    area, this vehicle being the only one Ellefritz
    saw in close proximity, less than 300 feet from
    where the shots were reported to have come
    from, the vehicle driving away from the area
    where shots reportedly originated, and upon
    seeing the patrol car stopping and then revers-
    ing slightly and moving away from Ellefritz,
    and the driver yelling that “they are still down
    there,” support the initial stop of that vehicle, if
    for no other reason than to inquire if they were
    witnesses to the shooting or to learn if they had
    been involved in the shooting.
    Rickmon conditionally pleaded guilty to the one-count in-
    dictment and reserved his right to appeal the district court’s
    denial of his motion to suppress. See Fed. R. Crim. P. 11(a)(2).
    was in the system’s coverage zone. We express no further opinion on the
    matter.

    On May 31, 2019, the district court sentenced Rickmon to 75
    months in prison and accordingly entered judgment. This
    timely appeal ensued.
    II. Discussion
    Under the Fourth Amendment, police “officers may con-
    duct a brief investigatory stop,” sometimes referred to as a
    Terry stop, “if they reasonably suspect that an individual has
    committed or is about to commit a crime.” Torry v. City of Chi-
    cago, 
    932 F.3d 579
    , 587 (7th Cir. 2019) (citing Terry v. Ohio, 
    392 U.S. 1
    , 20–22 (1968)). “Reasonable suspicion requires specific
    and articulable facts which, taken together with rational infer-
    ences from those facts, suggest criminal activity.” United
    States v. Lewis, 
    920 F.3d 483
    , 493 (7th Cir. 2019) (citation and
    internal quotation marks omitted). We review the objective
    reasonableness of a Terry stop de novo. See United States v.
    Watson, 
    900 F.3d 892
    , 895 (7th Cir. 2018).
    “While ‘inarticulate hunches’ are not enough, ‘reasonable
    suspicion is a lower threshold than probable cause’ and ‘con-
    siderably less than preponderance of the evidence.’” United
    States v. Adair, 
    925 F.3d 931
    , 935 (7th Cir. 2019) (citations omit-
    ted). Our task is to objectively examine the “totality of the cir-
    cumstances known to the officer at the time of the stop, in-
    cluding the experience of the officer and the behavior and
    characteristics of the suspect.” 
    Id. (citation omitted).
    We are
    mindful that “[r]easonable suspicion is a ‘commonsense, non-
    technical’ concept that deals with ‘the factual and practical
    considerations of everyday life on which reasonable and pru-
    dent men, not legal technicians, act.’” United States v. Wanjiku,
    
    919 F.3d 472
    , 488 (7th Cir. 2019) (citation omitted).
    No. 19-2054                                                   7
    Rickmon argues that ShotSpotter, standing on its own,
    should not allow police officers to stop a vehicle in the imme-
    diate vicinity of a gunfire report without any individualized
    suspicion of that vehicle. We generally agree with this propo-
    sition. Indeed, we question whether a single ShotSpotter alert
    would amount to reasonable suspicion. But we disagree with
    Rickmon’s conclusion that, in this case, the officer had only an
    “unparticular hunch”—rather than “specific and articulable
    facts”—that the car connected back to the crimes. As the dis-
    trict court found, the totality of the circumstances establishes
    the officer stopped the car for more reasons than just its loca-
    tion in ShotSpotter’s coverage zone.
    Rickmon is certainly correct that “[a] mere suspicion of il-
    legal activity at a particular place is not enough to transfer
    that suspicion to anyone who leaves that property.” United
    States v. Bohman, 
    683 F.3d 861
    , 864 (7th Cir. 2012); see also
    Ybarra v. Illinois, 
    444 U.S. 85
    , 91 (1979) (“[A] person’s mere
    propinquity to others independently suspected of criminal ac-
    tivity does not, without more, give rise to probable cause to
    search that person.”).
    He likens his case to Bohman; however, that decision is dis-
    tinguishable. As we have explained previously, “[i]n Bohman,
    police stopped a car exiting property that officers suspected
    of housing a methamphetamine lab. That suspicion resulted
    from a tip they had received, but when police stopped the car,
    they had not yet corroborated the tip in any way.” United
    States v. Richards, 
    719 F.3d 746
    , 757 (7th Cir. 2013) (citation
    omitted). We “found no reasonable suspicion for the stop be-
    cause the only information pointing to criminal activity was
    8                                                                 No. 19-2054
    the defendant’s emergence from property that an uncorrobo-
    rated tip accused of housing a meth lab. That alone was insuf-
    ficient.” 
    Id. (citation omitted).
        Rickmon asserts that the sergeant in Bohman had, in fact,
    more suspicion than Officer Ellefritz did here. He reasons that
    ShotSpotter is less reliable than the informant there (or a wit-
    ness in any other case) because it “does not provide any spe-
    cific information about suspects or vehicles, it simply records
    sounds.” Again, we can assume for the sake of argument that
    Officer Ellefritz needed “something extra” beyond the
    ShotSpotter report. But Rickmon mistakenly claims that the
    only other information the officer had when he made the stop
    was the radio dispatch. This was not the only other infor-
    mation the officer had to go on, and that is why Rickmon is
    unlike the defendant in Bohman.
    In cases where an officer stops a car departing a suspected
    crime scene, we have considered a number of circumstances
    relevant to our reasonable suspicion analysis: (1) the reliabil-
    ity of any reports to police; (2) the dangerousness of the crime;
    (3) the temporal and physical proximity of the stop to the
    crime; (4) any description of the vehicle and relevant traffic;
    and (5) the officer’s (or potentially even the department’s) ex-
    perience with criminal activity in that area. See United States v.
    Burgess, 
    759 F.3d 708
    , 710–11 (7th Cir. 2014); United States v.
    Brewer, 
    561 F.3d 676
    , 679 (7th Cir. 2009).3 We now apply these
    factors to Rickmon’s case.
    3 It is clear from our caselaw that a car’s vicinity to a suspected crime scene
    is rarely, if ever, the only articulable fact justifying a traffic stop. Moreover,
    Rickmon’s apparent bright-line rule that an officer must always identify a
    suspect or vehicle by matching real-time observation with a previous re-
    port is anathema to our evaluation of the totality of the circumstances. See
    No. 19-2054                                                                  9
    First, and as Rickmon concedes, Officer Ellefritz received
    two ShotSpotter alerts and two dispatches reporting a shoot-
    ing on North Ellis. The details gleaned from the 911 calls that
    the dispatcher passed on to Officer Ellefritz highlight that he
    did not merely act on uncorroborated information. Granted,
    we take Rickmon’s point that ShotSpotter is not comparable
    to an eyewitness or known informant; instead, we conclude it
    is analogous to an anonymous tipster. So, what Officer Elle-
    fritz ends up with is an anonymous tip from ShotSpotter that
    the 911 calls then independently confirmed. “Corroboration
    from multiple sources describing the general area and nature
    of the same crime exceeds the single police tip that alone can
    supply reasonable suspicion for a stop.” 
    Burgess, 759 F.3d at 710
    ; see also Florida v. J.L., 
    529 U.S. 266
    , 270–71 (2000) (similar).
    Here, the radio dispatches that Officer Ellefritz listened to
    on his way to the site of the shooting corroborated the
    ShotSpotter alerts by relaying accounts of cars leaving the
    scene and an individual running away from the shooting.4
    
    Harris, 568 U.S. at 245
    (rejecting a bright-line rule in the probable cause
    context because “[a] gap as to any one matter … should not sink the State’s
    case; rather, that ‘deficiency … may be compensated for, in determining
    the overall reliability of a tip, by a strong showing as to … other indicia of
    reliability.’” (quoting Illinois v. Gates, 
    462 U.S. 213
    , 233 (1983))); see also
    
    Brewer, 561 F.3d at 677
    –79 (concluding a traffic stop was reasonable even
    though, as in this case, the officer had no description of the vehicle or its
    occupants but did notice that it was the sole vehicle passing through the
    area’s only exit in the middle of the night).
    4 The government encourages us to rely on a later 911 call from an indi-
    vidual at 2227 North Ellis reporting “a bunch of gunfire” and five cars
    moving north as a circumstance relevant to our reasonable suspicion anal-
    ysis. But the police dispatcher did not convey this additional information
    to any of the officers en route. We need not rely on this fact to resolve this
    10                                                             No. 19-2054
    And “[m]ultiple … report[s] [of] shots fired in the same gen-
    eral area, creat[es] heightened suspicion of a serious
    appeal because it does not tip the scales one way or the other. Officer Elle-
    fritz was on firm footing when he stopped Rickmon’s car without these
    details.
    Even if this 911 call was decisive, however, it cannot justify the stop
    anyway because Officer Ellefritz did not know about it. See 
    Brewer, 561 F.3d at 677
    –78 (reasoning that facts learned after a traffic stop cannot sup-
    port it post hoc) (citations omitted). Officer Ellefritz must have been able to
    articulate his suspicion of Rickmon’s car when he stopped it and he cannot
    now articulate facts that were then unavailable to him. See United States v.
    Wilbourn, 
    799 F.3d 900
    , 909 (7th Cir. 2015). “The fact that the 911 operator
    turned out, after the fact, to have additional information which would
    have given the arresting officers reasonable suspicion cannot retroactively
    make their actions objectively reasonable.” United States v. Colon, 
    250 F.3d 130
    , 138 (2d Cir. 2001) (citation omitted).
    The government maintains that we should contemplate the “collective
    knowledge” of all law enforcement personnel, including the police dis-
    patcher, who were in communication regarding the investigation. But the
    government admits that the dispatcher did not broadcast this 911 call to
    the responding officers. And “imputed knowledge does not trump actual
    knowledge ….” United States v. Hicks, 
    531 F.3d 555
    , 560 (7th Cir. 2008) (ci-
    tation omitted). By conceding that the dispatcher did not transmit the con-
    tents of the 911 call to Officer Ellefritz, the government effectively rebutted
    any presumption of communication (and thus in favor of collective
    knowledge) between those two individuals. See United States v. Brown, 
    496 F.3d 1070
    , 1071 n.2 (10th Cir. 2007) (citing United States v. Shareef, 
    100 F.3d 1491
    , 1503–04 (10th Cir. 1996)).
    We conclude that the government cannot justify an investigative stop
    based on information that a 911 caller provides to a dispatcher who does
    not, in turn, notify the police on the scene. See 
    Colon, 250 F.3d at 137
    (“Im-
    puting information known only to the civilian operator and not conveyed
    to the dispatching and then arresting officers would extend the doctrine
    beyond its current jurisprudential parameters and vitiate the privacy safe-
    guards of the Fourth Amendment ….”).
    No. 19-2054                                                     11
    crime ….” 
    Id. at 711.
    Officer Ellefritz therefore had a good
    idea of what to be on the lookout for when he arrived.
    Second, Officer Ellefritz was responding to an emergency
    report of shots fired, not one of general criminality. We have
    repeatedly emphasized in our decisions that the inherent dan-
    ger of gun violence sets shootings apart from other criminal
    activity. See, e.g., 
    id. at 710–11
    (distinguishing Bohman from
    Brewer because of the apparent lack of immediate danger in
    Bohman). In Burgess, another case involving a shooting, we un-
    derscored that “the threat to public safety was serious, and
    the officers had to assume that it was continuing in process.”
    
    Id. at 711;
    see also 
    Brewer, 561 F.3d at 679
    (explaining the police
    “had a compelling reason to ask questions of the driver or
    passenger of the sole vehicle departing from a building com-
    plex in which shots had been fired (and not for the first time),
    in order to protect the police officers who were about to enter
    the complex.”).
    Indeed, an emergency report “can support an officer’s rea-
    sonable suspicion with less objective evidence to corroborate
    the report.” United States v. Williams, 
    731 F.3d 678
    , 684 (7th Cir.
    2013) (citing United States v. Hicks, 
    531 F.3d 555
    , 559–60 (7th
    Cir. 2008)). In Williams, we determined that an anonymous
    911 call justified a stop where “there was a large group of peo-
    ple being loud and waving guns in a location at which violent
    crime and drug activity is regularly reported.” 
    Id. This rule
    requiring less substantiation before making a stop based on
    an emergency report enables the police officer “to obtain for
    his own safety and that of the other officers as much infor-
    mation about the situation in the [area] as he could before
    they entered it in the dark.” 
    Brewer, 561 F.3d at 678
    .
    12                                                   No. 19-2054
    Third, Officer Ellefritz encountered Rickmon’s vehicle on
    the same block of the shooting five-and-a-half minutes after
    he received reports of shots fired. Rickmon claims that no
    criminal in their right mind would stick around a crime scene
    for that long. But we are not so sure. We know the shooting
    continued after the initial ShotSpotter alert. Moreover, this
    time frame is consistent with others in our caselaw. See, e.g.,
    
    Burgess, 759 F.3d at 709
    (“Just over four minutes had passed
    from the initial dispatch about gunshots to the officers’ report
    that Burgess was in custody.”); 
    Brewer, 561 F.3d at 677
    (noting
    that officers observed the suspicious car minutes after the
    original radio dispatch). Common sense counsels that a per-
    son may take minutes rather than seconds to flee for any num-
    ber of reasons, including the destruction of evidence, an in-
    jury sustained in the shooting, or a need to hide in place. As
    both a matter of fact and law, then, five-and-a-half minutes is
    not unduly long.
    Rickmon’s vehicle was also driving away from the site of
    the shooting on the only street leading from it. See United
    States v. Street,

    , 594 (7th Cir. 2019) (“The totality
    of circumstances, however, may provide additional and rea-
    sonable limits, particularly with respect to place and time, so
    as to allow a stop based on a fairly general description.”).
    Considering the facts here, it was a “natural surmise that
    whoever fired the shots” would be in the vehicle that Officer
    Ellefritz stopped.

    (stating that “the officers had … a street location
    to zero in on” when a car “pass[ed] them (going the other way
    and out of the area)” so “one might reasonably expect the
    shooter’s vehicle” to be that one). Based on these facts, it was
    No. 19-2054                                                   13
    rational for Officer Ellefritz to infer that Rickmon’s car partic-
    ipated in the gunfight because it was the only vehicle on the
    street of the shooting.
    Fourth, Officer Ellefritz did not have the description of any
    vehicle; however, it was 4:45 a.m. and there was no other traf-
    fic. Again, in such a scenario, “[t]he hour reinforce[s] the sus-
    picion” because we realistically expect few people on the road
    at that time.

    ; see also 
    Burgess, 759 F.3d at 711
    (“And because of the light traffic late on that Sunday
    night, there was a good chance that seeing Burgess’s car at
    that time and place was more than a coincidence.”). Hence, it
    was reasonable—not random—to pull Rickmon over. See
    
    Brewer, 561 F.3d at 679
    (ruling that the responding officer “was
    not acting randomly in deciding that the only car emerging
    from the apartment complex moments after he heard shots
    from within it should be intercepted”).
    Fifth, and finally, Officer Ellefritz knew that he was head-
    ing toward a block that he once patrolled and where in the
    past he had responded to shots-fired calls. Indeed, he esti-
    mated that he responded to these couple blocks once per
    night. To be fair, there was no evidence in the record that this
    was a so-called “high crime area.” Instead, Office Ellefritz tes-
    tified that he had personal knowledge of criminal activity in
    that part of Peoria. He was of course right to “draw on his
    own experience and specialized training to make inferences
    from and deductions about the cumulative information avail-
    able … that might well elude an untrained person.” United
    States v. Hill, 
    818 F.3d 289
    , 294 (7th Cir. 2016) (quoting United
    States v. Arvizu, 
    534 U.S. 266
    , 273 (2002)); see also 
    Brewer, 561 F.3d at 679
    (bearing in mind that the officer “had three years’
    experience with criminal activity in the particular housing
    14                                                        No. 19-2054
    complex …”). Simply put, we have never required officers “to
    ignore the relevant characteristics of a location in determining
    whether the circumstances are sufficiently suspicious to war-
    rant further investigation.” Illinois v. Wardlow, 
    528 U.S. 119
    ,
    124 (2000).
    Altogether, the circumstances here—the reliability of the
    police reports, the dangerousness of the crime, the stop’s tem-
    poral and physical proximity to the shots, the light traffic late
    at night, and the officer’s experience with gun violence in that
    area—provided reasonable suspicion to stop Rickmon’s vehi-
    cle. As in similar past challenges to automobile seizures,
    “there is ‘far more in this case … than … mere physical prox-
    imity’ to the criminal activity.” 
    Richards, 719 F.3d at 758

    ing United States v. Burrell, 
    963 F.2d 976

    . Multiple circumstances sepa-
    rate Rickmon’s case from others. In isolation, any one of those
    circumstances might not be sufficient.5 But viewed collec-
    tively, they start to seem suspicious. “In such a situation, it is
    reasonable for police to act quickly lest they lose the only op-
    portunity they may have to solve a recent violent crime or to
    interrupt an advancing one.” 
    Burgess, 759 F.3d at 711
    .
    III. Conclusion
    For the reasons stated above, the district court appropri-
    ately denied Rickmon’s motion to suppress. We therefore
    AFFIRM Rickmon’s resulting conviction and sentence.

    ple.”

    WOOD, Chief Judge, dissenting. If the Fourth Amendment
    stands for anything, it stands for the proposition that the po-
    lice cannot seize anyone without adequate, individualized
    reason to do so. Sometimes that reason must provide proba-
    ble cause for the seizure; sometimes it is enough that the po-
    lice have reasonable suspicion pointing to the person de-
    tained. But, with the exception of general roadblocks that sat-
    isfy the standards articulated in City of Indianapolis v. Edmond,
    
    531 U.S. 32
    (2000)—a situation that all agree is not present in
    the case before us—the police cannot simply force every per-
    son or every car to stop, in the hopes that they might uncover
    evidence of a crime. That would amount to a general warrant,
    precisely the evil that the drafters of the Fourth Amendment
    wanted to avoid.
    The question before us in this case is whether Officer
    Travis Ellefritz, of the Peoria (Illinois) Police Department, had
    the requisite individualized suspicion to order the car in
    which defendant Terrill Rickmon was riding to stop. Ellefritz
    was responding to two different reports he received around
    4:40 a.m. of gunshots having been fired in the immediate area
    of the 2200 block of North Ellis Street, within the city limits of
    Peoria. North Ellis is a two-block street that dead-ends at its
    south end, intersects with Archer Street in the middle, and
    “T’s” into West McClure Avenue at its north end. Top to bot-
    tom, North Ellis is a little more than 430 yards (four football
    fields plus a little).
    The majority recognizes that the validity of the stop rises
    or falls based only on the knowledge Ellefritz had at the time
    he stopped the car; no later-acquired facts can retroactively
    save it. Here is what he knew, and how he knew it:
    16                                                   No. 19-2054
       The ShotSpotter system in his squad car registered
    multiple gunshots at 2203 North Ellis around 4:40
    a.m. on July 29, 2018.
       That address is near the south end of the street,
    where it dead-ends.
       The police dispatcher announced two “shots fired”
    alerts detected by ShotSpotter over the radio.
       The police dispatcher informed Ellefritz that a 911
    call had come in reporting gunfire on North Ellis.
       The 911 caller also said that there were several cars
    leaving the location and one black male on foot.
       Between three and a half and five minutes after re-
    ceiving the initial ShotSpotter dispatch, Ellefritz
    reached North Ellis Street.
       As he drove south on the street, he saw a car turn
    from the east side of the street and proceed north-
    bound. He saw no other cars on the road.
    Based on that information, Ellefritz decided to stop the car. He
    turned on his emergency lights, maneuvered his car to block
    the northbound land, and the car began to stop. It came to a
    complete halt when Ellefritz yelled at the occupants to stop
    and stay where they were.
    The only thing that distinguished the car Ellefritz chose to
    stop was that it existed, and it was the only car on the street at
    that early hour of the morning. None of the information he
    had received even hinted at the shooter’s car’s make, color,
    age, style, or anything else. Indeed, though I do not rely on
    this subjective fact, Ellefritz frankly admitted that he would
    No. 19-2054                                                    17
    have stopped literally any car he saw on North Ellis based on
    the information he had.
    It appears that it is illegal for a person to discharge a gun
    within the corporate limits of Peoria, other than at a licensed
    shooting gallery, gun club, or rifle club. Peoria City Ordi-
    nance, sec. 20-161(a). It was thus reasonable for Ellefritz to
    think that the discharge of a gun was unauthorized, despite
    all the changes in gun regulation that have followed the Su-
    preme Court’s decision in District of Columbia v. Heller, 
    554 U.S. 570
    (2008). But virtually nothing connected those sounds
    with the car he decided to stop, or indeed with any car at all—
    it was just as likely that the shooter had retreated into a nearby
    house or fled on foot (as the 911 caller indicated).
    My colleagues are willing to assume that because, some
    five minutes after the shots were heard, this was the only car
    on North Ellis, the people in it must have been associated with
    the shots. But that is pure speculation. July 29 fell on a Sunday
    in 2018. Nonetheless, some workplaces operate on a seven-
    day week, and early-morning shifts are by no means unheard-
    of: think of production workers, grocery stockers, transporta-
    tion workers, bakers, and baristas, to name just a few. Or the
    driver might have needed to go from Peoria to Chicago, or
    Springfield, or St. Louis, for social reasons or a business ap-
    pointment and wanted an early start. Or maybe the driver
    was at a late party. The time of day, and the fact that the road
    was largely empty, do not add up to anything.
    The 911 caller reported a man running away from the area
    where the noises were heard, but Ellefritz did not stop a run-
    ning man. And the street is so short – about a quarter of a mile
    (one lap around a track)—that the runner would have been
    long gone before Ellefritz pulled up in his car. Again, one
    18                                                  No. 19-2054
    could speculate that the shooter stayed around and then got
    into the car that Ellefritz stopped. But that speculation is ut-
    terly unsupported. It was equally plausible to speculate that
    (a) the shooter ran across the grass to the parking lot south of
    the dead end and quickly slipped out of sight, or (b) the
    shooter took refuge in one of the surrounding houses, or (c)
    the shooter crossed over Archer Street and rendezvoused
    with his ride a safe block away.
    My colleagues also stress that Ellefritz believed that he was
    responding to an emergency, because gunshots always con-
    note emergency. Perhaps they do. But how much does this
    prove? Would it have entitled the police to force their way
    into every house on North Ellis, to make sure that the shooter
    was not threatening anyone in those houses? Would it have
    allowed the police to stop any and every car they saw within
    1,000 feet of the point that ShotSpotter identified? My answer
    to both those questions is no. And I cannot agree with my col-
    leagues that a single car proceeding north, at the speed limit,
    signals an emergency. There was some talk in the district
    court about North Ellis being part of a “high crime” area, but
    my colleagues admit that “there was no evidence in the record
    that this was a so-called ‘high crime area.’” Ante at 13.
    Finally, my colleagues worry that compliance with the
    Fourth Amendment here might have allowed a culpable per-
    son to avoid being arrested. But there are two responses to
    this point. First, the requirement that the police must have ei-
    ther probable cause or at least reasonable suspicion before ar-
    resting someone will, in some instances, hamper their activi-
    ties. That is exactly what happened in Ybarra v. Illinois, 
    444 U.S. 85
    (1979), when the Supreme Court held constitutionally
    impermissible a search warrant that allowed the police to
    No. 19-2054                                                    19
    search, pat down, and seize any of the patrons of a small tav-
    ern. It did so despite the fact that the search revealed that Ven-
    tura Ybarra possessed heroin. Second, Rickmon’s offense was
    being a felon in possession of a firearm. To this day, no one
    has suggested that he was the shooter. If anything, the fact
    that his leg had been wounded by a bullet indicated (after the
    fact) that he was a victim of the shooter.
    I would hold that Rickmon’s motion to suppress the evi-
    dence should have been granted, and I would remand for fur-
    ther proceedings. I therefore respectfully dissent.
