    ____________________________________)
    A deputy sheriff investigating an emergency call of a fight in progress
    pulled his patrol car behind defendant Brown’s parked vehicle and activated the
    emergency lights. Approaching the car, he saw Brown sitting behind the wheel,
    apparently intoxicated. We conclude Brown was detained when the emergency
    lights were activated. A reasonable person under the circumstances would not
    have felt free to leave and Brown submitted to the show of authority by remaining
    in his parked car. We further conclude that Brown’s brief detention was supported
    by reasonable suspicion. Accordingly, we affirm the Court of Appeal’s judgment.
    I. BACKGROUND
    About 10:37 p.m. on a Sunday night, the San Diego County Sheriff’s
    Department received an emergency call on its 911 line. The caller confirmed his
    address with the dispatcher and reported some people were fighting in an alley
    behind his home on Georgia Street in Imperial Beach. He could hear screaming
    and one person said, “the gun was loaded.” The following colloquy ensued:
    “911: And it sounds physical?
    1
    “[Caller]: Yeah, they are fighting right now. You hear the screams?
    “911: I hear it. So, you heard one person say they have a gun and it’s
    loaded?
    “[Caller]: Yes.”
    The caller estimated that more than four people were involved, and said the
    participants lived two houses down from him on the same block. The dispatcher
    sent an officer to the scene and stayed on the line with the caller. The dispatcher
    asked the caller to report any other mention of a weapon and asked if anyone had
    gotten into a car. The caller said there was a car in the alley, facing south toward
    Fern Avenue. He then relayed that he knew a squad car had arrived because he
    heard the siren and saw the lights. When the caller confirmed the officer was on
    the scene, the call ended. It had lasted approximately four minutes.
    A dispatcher told Deputy Sheriff Geasland that four suspects were fighting
    in the alley behind the caller’s residence on Georgia Street between Coronado and
    Fern Avenues, and that “somebody may have said ‘something about a loaded
    gun.’ ” Geasland was on the scene within three minutes. As he drove north in the
    alley from Fern towards Coronado, he saw a car coming towards him and away
    from the fight location. Geasland yelled to the driver, Brown, “Hey. Did you see
    a fight?” Brown did not respond and kept driving. Geasland continued down the
    alley but saw no one.
    Geasland suspected Brown might have been involved in the fight because
    he had come from that location and had failed to acknowledge the deputy’s
    question. He was also concerned about the report of a weapon and the possibility
    that Brown may have been injured. He turned around and drove in the direction
    Brown had taken.
    Geasland found Brown’s car parked on Georgia Street, a few houses down
    from the house behind which the fight had occurred. He pulled behind Brown’s
    2
    car and activated the overhead emergency lights on his patrol car. (See discussion,
    post, at pp. 9-10.) He approached and spoke with Brown, who was in the driver’s
    seat. Brown identified himself and produced his driver’s license. He appeared
    upset and flustered. He was mumbling and had watery, bloodshot eyes. Geasland
    could smell alcohol coming from the car. He asked if Brown had been drinking
    and whether he had been involved in the fight. Brown admitted both. A traffic
    deputy arrived and conducted further investigation for driving under the influence
    (DUI).
    Charged with felony DUI, Brown moved to suppress evidence of his
    physical condition, statements, and breath test results as the fruits of an unlawful
    detention. (Pen. Code, § 1538.5.) The trial court denied the motion, concluding
    Brown had not been detained until the deputy saw signs of intoxication. At that
    point, the deputy had a reasonable suspicion that Brown had been driving under
    the influence.
    Brown pleaded guilty to driving with a blood-alcohol concentration (BAC)
    over .08 percent (Veh. Code, § 23152, subd. (b)) and admitted a BAC exceeding
    .15 percent (id. § 23578). He also admitted suffering three prior DUI convictions
    (id. §§ 23550, subd. (a), 23626), and was sentenced to two years in county jail
    (Pen. Code, § 1170, subd. (h)).
    The Court of Appeal affirmed the conviction, holding that “when a vehicle
    is already stopped, without police action, merely activating emergency lights on a
    police vehicle, without more, does not constitute a seizure within the Fourth
    Amendment.” Alternatively, the court held that, if a detention did occur, it was
    supported by reasonable suspicion.
    3
    II. DISCUSSION
    An officer may approach a person in a public place and ask if the person is
    willing to answer questions. If the person voluntarily answers, those responses,
    and the officer’s observations, are admissible in a criminal prosecution. (Florida
    v. Bostick (1991) 
    501 U.S. 429
    , 434 (Bostick); Florida v. Royer (1983) 
    460 U.S. 491
    , 497 (Royer) (plur. opn. of White, J.).) Such consensual encounters present no
    constitutional concerns and do not require justification. (Bostick, at p. 434.)
    However, “when the officer, by means of physical force or show of authority, has
    in some way restrained the liberty of a citizen,” the officer effects a seizure of that
    person, which must be justified under the Fourth Amendment to the United States
    Constitution. (Terry v. Ohio (1968) 
    392 U.S. 1
    , 19, fn. 16 (Terry); accord,
    Bostick, at p. 434.) In situations involving a show of authority, a person is seized
    “if ‘in view of all of the circumstances surrounding the incident, a reasonable
    person would have believed that he was not free to leave,’ ” or “ ‘otherwise
    terminate the encounter,’ ” (Brendlin v. California (2007) 
    551 U.S. 249
    , 254-255
    (Brendlin)), and if the person actually submits to the show of authority (id. at p.
    254).
    The critical question here is when Brown’s detention occurred. If the
    encounter with Geasland was consensual, it required no justification. When
    Geasland then saw obvious signs of intoxication, a detention to investigate drunk
    driving was warranted. But if Geasland effected a detention when he turned on
    the emergency lights, he was required to “point to specific articulable facts that,
    considered in light of the totality of the circumstances, provide some objective
    manifestation that [Brown] may be involved in criminal activity.” (People v.
    Souza (1994) 
    9 Cal.4th 224
    , 231 (Souza); accord, United States v. Cortez (1981)
    
    449 U.S. 411
    , 417-418 (Cortez); Terry, 
    supra,
     392 U.S. at pp. 17, 20-21.)
    4
    In reviewing the trial court’s suppression ruling, we defer to its factual
    findings if supported by substantial evidence. We independently assess the legal
    question of whether the challenged search or seizure satisfies the Fourth
    Amendment. (People v. Leyba (1981) 
    29 Cal.3d 591
    , 596-597.)
    A. Detention of a Driver in a Stopped Vehicle
    Here we consider two questions. One, when an officer approaches a
    motorist in a parked car, what differentiates between a consensual encounter and a
    detention? Two, what is required to demonstrate submission to a show of
    authority?
    In People v. Bailey (1985) 
    176 Cal.App.3d 402
     (Bailey) an officer stopped
    behind the defendant’s parked car and activated his emergency lights. (Id. at p.
    404.) Applying the test from United States v. Mendenhall (1980) 
    446 U.S. 544
    ,
    554 (Mendenhall), the court concluded a detention had occurred because “[a]
    reasonable person to whom the red light from a vehicle is directed would be
    expected to recognize the signal to stop or otherwise be available to the officer.
    Any reasonable person in a similar situation would expect that if he drove off, the
    officer would respond by following with red light on and siren sounding in order
    to accomplish control of the individual.” (Bailey, at pp. 405-406.)1
    The Court of Appeal here faulted Bailey for overlooking a critical point.
    Relying on California v. Hodari D. (1991) 
    499 U.S. 621
     (Hodari D.), it held that
    “there needs to be some evidence that the person yielded to that show of authority.
    In the case of a stopped vehicle approached by police, we believe there must be
    something more than merely activating the red lights to accomplish a detention,
    1      Justice Agliano dissented on the ground the officer’s observations were
    unrelated to and independent of his use of emergency lights. (Bailey, supra, 176
    Cal.App.3d at pp. 407-408.)
    5
    because, as the majority in Bailey, supra, 
    176 Cal.App.3d 402
     acknowledged, if
    you do not yield, police may chase you.” The court reasoned: “[P]olice will give
    chase, but mere demands, or even pursuit, are not seizures until the citizen accepts
    the command, either direct or implied, or when the police succeed in restraining
    that person.” Applying Hodari D., the appellate court upheld the trial court’s
    finding “that Brown was not stopped by police nor was he detained by the deputy
    until after the deputy approached the car and immediately observed clear
    indications of intoxication.”
    Bailey provides the more persuasive authority. Hodari D. is distinguishable
    and inaptly applied here. In Hodari D., a group of youths ran away when they saw
    two officers driving in an unmarked police car. The officers gave chase. As he
    ran, Hodari tossed away a small rock of crack cocaine. He was subsequently
    tackled by an officer. (Hodari D., 
    supra,
     499 U.S. at pp. 622-623.) The question
    before the Supreme Court was “whether, with respect to a show of authority as
    with respect to application of physical force, a seizure occurs even though the
    subject does not yield. We hold that it does not.” (Id. at p. 626, italics added.)
    The court emphasized that a seizure requires either the use of force or submission
    to an assertion of authority. (Id. at pp. 626-627.) No state action directed at
    Hodari caused him to flee. Initially the officers had made no attempt to detain
    him. They were merely driving down the street when the minor chose to run
    away. Nonetheless, the court concluded: “assuming that [the officer’s] pursuit in
    the present case constituted a ‘show of authority’ enjoining Hodari to halt, since
    Hodari did not comply with that injunction he was not seized until he was
    tackled.” (Id. at p. 629, italics added.) Thus, the cocaine, discarded before that
    seizure, was not illegally obtained. (Ibid.)
    This case is different. Brown did not drive away when Geasland turned on
    the emergency lights. Rather, he stayed in his parked car as the officer
    6
    approached. The United States Supreme Court addressed a similar circumstance
    in Brendlin, supra, 
    551 U.S. 249
    . There, an officer stopped a car in which
    Brendlin was a passenger. Drugs were found both in the car and on Brendlin’s
    person. (Id. at pp. 252-253 & fn. 2.) The court held that Brendlin was seized
    during the traffic stop. (Id. at p. 251.)
    The court first addressed the applicable standard: “when an individual’s
    submission to a show of governmental authority takes the form of passive
    acquiescence, there needs to be some test for telling when a seizure occurs in
    response to authority, and when it does not. The test was devised by Justice
    Stewart in United States v. Mendenhall, 
    446 U.S. 544
     (1980), who wrote that a
    seizure occurs if ‘in view of all of the circumstances surrounding the incident, a
    reasonable person would have believed that he was not free to leave,’ 
    id., at 554
    (principal opinion).” (Brendlin, 
    supra,
     551 U.S. at p. 255.) The court
    subsequently adopted Justice Stewart’s touchstone. (Ibid., citing Hodari D.,
    
    supra,
     499 U.S. at p. 627; Michigan v. Chesternut (1988) 
    486 U.S. 567
    , 573
    (Chesternut); INS v. Delgado (1984) 
    466 U.S. 210
    , 215 (Delgado).) In Bostick,
    
    supra,
     
    501 U.S. 429
    , the court noted that, in some cases, a person may not wish to
    leave the location of a police encounter but may also not wish to speak with, or
    otherwise comply with, an officer’s request. In such a circumstance, the “coercive
    effect of the encounter” is better measured by asking whether “a reasonable person
    would feel free to decline the officers’ requests or otherwise terminate the
    encounter.” (Id. at p. 436.)
    The Brendlin court concluded that “any reasonable passenger [in Brendlin’s
    circumstances] would have understood the police officers to be exercising control
    to the point that no one in the car was free to depart without police permission.”
    (Brendlin, supra, 551 U.S. at p. 257.) It further held that Brendlin had
    demonstrated submission to authority notwithstanding the fact that only the driver
    7
    controlled the moving vehicle. “[W]hat may amount to submission depends on
    what a person was doing before the show of authority: a fleeing man [like Hodari
    D.] is not seized until he is physically overpowered, but one sitting in a chair may
    submit to authority by not getting up to run away. Here, Brendlin had no effective
    way to signal submission while the car was still moving on the roadway, but once
    it came to a stop he could, and apparently did, submit by staying inside.” (Id. at p.
    262.)2
    Similarly, here, Brown submitted to the deputy’s show of authority by
    staying in his car at the scene. The Court of Appeal effectively expanded
    Brendlin’s objective test by requiring that there “needs to be some evidence that
    the person yielded.” It failed to explain, however, what additional evidence would
    satisfy this expanded standard. The Court of Appeal’s approach is both
    impractical and unnecessary. “[W]hen an individual’s submission to a show of
    governmental authority takes the form of passive acquiescence,” we simply
    consider whether, objectively, “ ‘in view of all of the circumstances surrounding
    the incident, a reasonable person would have believed that he was not free to
    leave,’ ” or “ ‘otherwise terminate the encounter.’ ” (Brendlin, 
    supra,
     551 U.S. at
    p. 255, quoting Mendenhall, 
    supra,
     446 U.S. at p. 554 and Bostick, 
    supra,
     501
    U.S. at p. 436.)
    2       The People construe this passage as dictum but do not further defend the
    characterization. On the contrary, the high court specifically identified the issue as
    one of three premises underlying our state court holding with which it disagreed.
    (Brendlin, 
    supra,
     551 U.S. at p. 259; see People v. Brendlin (2006) 
    38 Cal.4th 1107
    , 1118 [holding that “defendant has not shown that he, as the passenger, was
    the subject of the deputy’s show of authority or that he actually submitted to it”
    (italics added)].) Indeed, the high court’s conclusion that the stop effected a
    seizure of Brendlin necessarily depended on a finding that Brendlin submitted to
    the show of authority.
    8
    The People take a different approach to justifying Deputy Geasland’s
    conduct. They argue that Geasland’s actions did not amount to a detention until
    after he approached Brown’s car on foot and noted symptoms of intoxication. The
    argument fails.
    The Supreme Court has long recognized that activating sirens or flashing
    lights can amount to a show of authority. (Chesternut, supra, 486 U.S. at p. 575.)
    Here, Deputy Geasland arrived at the scene with lights and sirens activated.
    Brown did not respond to Geasland’s initial inquiry in the alley. After checking
    the scene, Geasland drove after Brown. He stopped behind Brown’s legally
    parked car and turned on his emergency lights. Under these circumstances, a
    reasonable person in Brown’s position would have perceived Geasland’s actions
    as a show of authority, directed at him and requiring that he submit by remaining
    where he was. As a sister-state court has observed: “We see little difference,
    from the perspective of the occupants in the vehicle, [between] turning on the blue
    lights behind a moving vehicle and turning on the blue lights behind a parked
    vehicle. The lights still convey the message that the occupants are not free to
    leave.” (State v. Gonzalez (Tenn.Ct.App. 2000) 
    52 S.W.3d 90
    , 97; accord, Smith
    v. State (Fla.Ct.App. 2012) 
    87 So.3d 84
    , 87-88 [officer detained defendant by
    parking adjacent to defendant’s lawfully parked vehicle and activating his
    emergency lights and spotlight]; State v. Morris (Kan. 2003) 
    72 P.3d 570
    , 573-
    574, 577-579 [officer detained defendant by activating emergency lights and
    spotlights behind defendant’s truck parked off the freeway].)
    The People counter that the record fails to establish whether Deputy
    Geasland activated “ ‘emergency lights,’ ‘overhead lights,’ red and blue flashing
    lights, solid lights, amber lights, white lights, or spotlights.” Urging that this is an
    important, if not dispositive, factor, they claim that the ambiguity in the record
    must be construed in favor of the trial court’s order denying the suppression
    9
    motion. (People v. Glaser (1995) 
    11 Cal.4th 354
    , 362 (Glaser).) They fail to
    persuade.
    Geasland testified that he “activated [his] lights.” When the trial court
    sought clarification on that point, the deputy confirmed that his actions were
    consistent with having made a traffic stop. The most logical inference to be drawn
    from this testimony is that Geasland turned on his overhead emergency lights,
    which included a combination of red and blue lights.3 The district attorney offered
    no dispute and the trial court made no findings to the contrary. In their briefing
    before the Court of Appeal, the People again failed to challenge the point, and the
    Court of Appeal wrote that the deputy had activated “the patrol car’s overhead
    emergency lights.” The People did not petition for rehearing. (See Cal. Rules of
    Court, rule 8.500(c).) On the contrary, they sought publication of the originally
    unpublished opinion because it expressly disagreed with the holding in Bailey,
    supra, 176 Cal.App.3d at pages 405-406, that a detention occurs when an officer
    activates his emergency lights. When Brown petitioned for review, the People did
    not file an answer challenging the factual record. Accordingly, we accept the
    Court of Appeal’s statement that the deputy activated his overhead emergency
    lights. (See People v. Nelson (2008) 
    43 Cal.4th 1242
    , 1247.)
    The People argue that, because Brown had voluntarily stopped his car
    before the deputy’s display of authority, the appropriate inquiry is whether “ ‘a
    reasonable person would feel free to decline the officers’ requests or otherwise
    terminate the encounter.’ ” (Brendlin, supra, 551 U.S. at p. 255, quoting Bostick,
    3       See Vehicle Code, sections 25252 (“Every authorized emergency vehicle
    shall be equipped with at least one steady burning red warning lamp . . . .”),
    25258, subdivision (b) (“An authorized emergency vehicle used by a peace officer
    . . . may, in addition, display a steady or flashing blue warning light . . . .”).
    10
    supra, 501 U.S. at pp. 435-436, italics added.) According to the People, the
    encounter did not begin until the deputy walked up to Brown’s car. Not so.
    The People’s argument does not acknowledge the evolution of the high
    court’s test. The simple “not free to leave” test was first articulated in
    Mendenhall, supra, 446 U.S. at page 554. The test was augmented in Bostick to
    encompass a situation in which a person might not want or be able to leave his
    location because of circumstances “independent of police conduct,” but had no
    desire to interact with officers. (Bostick, 
    supra,
     501 U.S. at p. 436.) In Bostick,
    police officers boarded a bus and asked to see the defendant’s identification and
    ticket, then asked to search his luggage. (Id. at pp. 431-432.) Bostick argued that
    a reasonable person in his position would not have felt “free to leave” the bus
    because, if it left, he would have been stranded without his bag. (Id. at p. 435.)
    The Supreme Court rejected this argument: “Bostick’s freedom of movement was
    restricted by a factor independent of police conduct—i. e., by his being a
    passenger on a bus. Accordingly, the ‘free to leave’ analysis on which Bostick
    relies is inapplicable. In such a situation, the appropriate inquiry is whether a
    reasonable person would feel free to decline the officers’ requests or otherwise
    terminate the encounter.” (Id. at p. 436.)
    The circumstances here are more similar to Brendlin and Mendenhall than
    to Bostick. Acting on his own, Brown had stopped his car temporarily on the side
    of the road. Nothing, other than the officer’s show of authority, prevented his
    willful departure. He remained in the driver’s seat with his foot on the brake.
    There was no evidence that Brown’s car was disabled. He had been driving it
    minutes before, despite his intoxication. Brown could also have left on foot,
    leaving his car legally parked. The high court in Brendlin found it appropriate to
    consider whether a reasonable passenger in a stopped car would have felt free to
    “depart without police permission.” (Brendlin, supra, 551 U.S. at p. 257, italics
    11
    added; see also ibid. [a passenger’s “attempt to leave the scene would be so
    obviously likely to prompt an objection from the officer that no passenger would
    feel free to leave in the first place”].) As a result, our analysis here focuses on
    whether a reasonable person in Brown’s position would have felt free to leave.
    Finally, the People argue that “[t]here is no indication that [Brown] was
    even aware of the officer’s presence until after the officer approached [Brown]’s
    car on foot.” They maintain that “[t]here must be some additional law
    enforcement action that directs the officer’s actions toward that individual—such
    as issuing oral commands or questions toward that person or, as here, approaching
    the car on foot and making contact with the person—before a reasonable person
    would become aware he or she was engaged in an encounter with the police.” The
    argument is not supported by substantial evidence. Geasland did not testify that
    Brown was unconscious, probing under the seat, or otherwise distracted. The
    reasonable inference to be drawn from the record was that Brown was aware of the
    deputy’s overhead emergency lights flashing in the dark immediately behind his
    car.
    To be clear, we do not adopt a bright-line rule that an officer’s use of
    emergency lights in close proximity to a parked car will always constitute a
    detention of the occupants. “[A]ny assessment as to whether police conduct
    amounts to a seizure implicating the Fourth Amendment must take into account
    ‘ “all of the circumstances surrounding the incident” ’ in each individual case.”
    (Chesternut, supra, 486 U.S. at p. 572, quoting Delgado, 
    supra,
     466 U.S. at p.
    215.) As an example, a motorist whose car had broken down on the highway
    might reasonably perceive an officer’s use of emergency lights as signaling that
    the officer has stopped to render aid or to warn oncoming traffic of a hazard, rather
    than to investigate crime. Ambiguous circumstances may be clarified by whether
    other cars are nearby or by the officer’s conduct when approaching. (See Wilson
    12
    v. Superior Court (1983) 
    34 Cal.3d 777
    , 791 & fn. 11; People v. Garry (2007) 
    156 Cal.App.4th 1100
    , 1110-1112.) Here, no circumstances would have conveyed to a
    reasonable person that Deputy Geasland was doing anything other than effecting a
    detention. Under the totality of these circumstances, Brown was detained when
    Geasland stopped behind the parked car and turned on his emergency lights.
    B. Reasonable Suspicion to Detain
    The next question is whether the detention was supported by reasonable
    suspicion. The circumstances here include a reliable citizen’s report of a violent
    fight potentially involving a firearm, the deputy’s very quick response time, and
    Brown’s presence near the scene of the fight in the otherwise vacant alley. These
    facts justified this brief detention.
    The Supreme Court recently summarized the governing principles: “The
    Fourth Amendment permits brief investigative stops . . . when a law enforcement
    officer has ‘a particularized and objective basis for suspecting the particular
    person stopped of criminal activity.’ United States v. Cortez, 
    449 U.S. 411
    , 417-
    418 (1981); see also Terry v. Ohio, 
    392 U.S. 1
    , 21-22 (1968). The ‘reasonable
    suspicion’ necessary to justify such a stop ‘is dependent upon both the content of
    information possessed by police and its degree of reliability[,]’ Alabama v. White,
    
    496 U.S. 325
    , 330 (1990) . . . . tak[ing] into account ‘the totality of the
    circumstances . . . .’ Cortez, 
    supra, at 417
    . Although a mere ‘ “hunch” ’ does not
    create reasonable suspicion, Terry, 
    supra, at 27
    , the level of suspicion the standard
    requires is ‘considerably less than proof of wrongdoing by a preponderance of the
    evidence,’ and ‘obviously less’ than is necessary for probable cause, United States
    v. Sokolow, 
    490 U.S. 1
    , 7 (1989).” (Navarette v. California (2014) __ U.S. __
    [
    134 S.Ct. 1683
    , 1687] (Navarette); accord, Souza, 
    supra,
     9 Cal.4th at pp. 229-
    231.) “[W]here a reasonable suspicion of criminal activity exists, ‘the public
    rightfully expects a police officer to inquire into such circumstances “in the proper
    13
    exercise of the officer’s duties.” ’ ” (People v. Wells (2006) 
    38 Cal.4th 1078
    , 1083
    (Wells), quoting In re Tony C. (1978) 
    21 Cal.3d 888
    , 894.)
    Navarette found an anonymous motorist’s 911 call sufficiently reliable to
    support the traffic stop of a pickup truck on suspicion of drunk driving.
    (Navarette, 
    supra,
     __ U.S. at p. __ [134 S.Ct. at pp. 1688-1690].) Considering the
    factors outlined in that case, we reach a similar conclusion here.
    First, a caller’s personal knowledge “lends significant support to the tip’s
    reliability.” (Navarette, 
    supra,
     __ U.S. at p. __ [134 S.Ct. at p. 1689]; accord,
    People v. Dolly (2007) 
    40 Cal.4th 458
    , 467 (Dolly); Wells, 
    supra,
     38 Cal.4th at p.
    1087.) The caller here reported he was witnessing a fight in the alley outside of
    his home. He said at least four people, who lived two doors away from him, were
    involved. He heard one person claim to have a loaded gun.
    Second, the caller’s report was contemporaneous, a factor that “has long
    been treated as especially reliable.” (Navarette, supra, __ U.S. at p. __ [134 S.Ct.
    at p. 1689]; accord, Dolly, 
    supra,
     40 Cal.4th at p. 467; Wells, 
    supra,
     38 Cal.4th at
    p. 1087.) Indeed, the dispatcher confirmed she could hear people screaming in the
    background of the call, further corroborating the caller’s account. The caller also
    told the dispatcher that he could hear the siren and see the lights of the responding
    patrol car.
    “Another indicator of veracity is the caller’s use of the 911 emergency
    system,” which “has some features that allow for identifying and tracing callers,
    and thus provide[s] some safeguards against making false reports with immunity.”
    (Navarette, 
    supra,
     __ U.S. at p. __ [134 S.Ct. at p. 1689]; accord, Dolly, 
    supra,
     40
    Cal.4th at p. 467.) This 911 call was recorded, and the caller confirmed his
    address with the dispatcher. (Navarette, at p. __ [134 S.Ct. at p. 1690]; Dolly, at p.
    467 & fn. 2.)
    14
    Finally, as this court has observed, private citizens who report criminal
    activity generally have no bias or motive other than good citizenship, and
    therefore tend to be reliable. (People v. Ramey (1976) 
    16 Cal.3d 263
    , 268-269;
    People v. Brueckner (1990) 
    223 Cal.App.3d 1500
    , 1504; see Illinois v. Gates
    (1983) 
    462 U.S. 213
    , 233-234.)
    Brown relies on Florida v. J. L. (2000) 
    529 U.S. 266
    , but that case is
    distinguishable. The high court in J. L. held that police lacked reasonable
    suspicion to detain and frisk the defendant based on an anonymous telephone tip
    claiming a young Black man in a plaid shirt standing at a particular bus stop was
    carrying a gun. (Id. at pp. 272-274.) The court stated that “[a]ll the police had to
    go on in this case was the bare report of an unknown, unaccountable informant
    who neither explained how he knew about the gun nor supplied any basis for
    believing he had inside information about J. L.” (Id. at p. 271.) Navarette
    recently distinguished J. L. on the ground that the caller in Navarette provided
    more than a “bare-bones tip.” (Navarette, supra, __ U.S. at p. __ [134 S.Ct. at p.
    1692].) J. L. is likewise distinguishable here. This caller’s eyewitness knowledge,
    contemporaneous reporting, use of the 911 system, and confirmation of his
    address provided additional indicia of reliability. Further, although the caller did
    not personally observe an assault with a firearm (cf. Dolly, supra, 40 Cal.4th at p.
    465), he did hear one of the people involved claim to have a loaded gun. In the
    context of a fight in progress, such a claim suggests a credible threat. The caller’s
    contemporaneous report of this declaration was more reliable than the amorphous
    circumstances in J. L.
    Brown further argues that the caller’s reliability must be assessed based on
    the facts known to Deputy Geasland, not the 911 dispatcher, and that Geasland
    was unaware of the circumstances under which the call was placed. The argument
    is unpersuasive. An officer may arrest or detain a suspect “based on information
    15
    received through ‘official channels.’ ” (People v. Madden (1970) 
    2 Cal.3d 1017
    ,
    1021; see United States v. Hensley (1985) 
    469 U.S. 221
    , 230-233 (Hensley).) If a
    911 call “has sufficient indicia of reliability . . . a dispatcher may alert other
    officers by radio, who may then rely on the report, [citation], even though they
    cannot vouch for it.” (U.S. v. Cutchin (D.C. Cir. 1992) 
    956 F.2d 1216
    , 1217-1218;
    accord, U.S. v. Torres (3d Cir. 2008) 
    534 F.3d 207
    , 210.) However, upon proper
    objection (People v. Rogers (1978) 
    21 Cal.3d 542
    , 547-548), “ ‘ “the People must
    prove that the source of the information is something other than the imagination of
    the officer who does not become a witness.” ’ ” (Madden, at p. 1021, quoting
    Remers v. Superior Court (1970) 
    2 Cal.3d 659
    , 666; accord, People v. Harvey
    (1958) 
    156 Cal.App.2d 516
    , 523-524 (conc. opn. of Dooling & Draper, JJ.).) This
    requirement can be met by calling the police dispatcher as a witness at the
    suppression hearing or by introducing a recording of the 911 call. (In re Richard
    G. (2009) 
    173 Cal.App.4th 1252
    , 1260; People v. Orozco (1981) 
    114 Cal.App.3d 435
    , 444.) Here, the dispatcher was present at the hearing but was not called
    because Brown stipulated to admission of the 911 recording into evidence. That
    recording provided ample basis to review the caller’s reliability. (Dolly, 
    supra,
     40
    Cal.4th at p. 467, fn. 2; People v. Lazanis (1989) 
    209 Cal.App.3d 49
    , 57.)4
    4       Brown further argues that it is improper to impute the 911 dispatcher’s
    knowledge of the circumstances of the call to Deputy Geasland because the
    imputed knowledge doctrine applies only to other law enforcement officials, and
    “[a] civilian 911 operator” does not meet that criteria. He relies on U.S. v. Colon
    (2d Cir. 2001) 
    250 F.3d 130
    , 136-137. We need not decide if Colon is persuasive
    authority because Brown forfeited this argument by failing to object on that basis
    in the trial court. His lack of objection and stipulation to admission of the
    recording gave the People no reason to address such an argument or present
    additional evidence below. (Dolly, supra, 40 Cal.4th at p. 466, fn. 1.)
    16
    As in Navarette, 
    supra,
     __ U.S. at page __ [134 S.Ct. at pp. 1688-1690],
    this 911 caller demonstrated adequate indicia of reliability to credit his account of
    a violent fight in progress involving several people and possibly a loaded gun in
    the alley behind the caller’s residence.
    The next question is whether the deputy could reasonably suspect Brown
    had been involved in the fight. (Michigan v. Summers (1981) 
    452 U.S. 692
    , 699-
    700; Cortez, 
    supra,
     449 U.S. at pp. 417-418; Terry, 
    supra,
     392 U.S. at pp. 16-19.)
    The absence of any suspect descriptions makes this a close question. Nonetheless,
    we conclude that the totality of the circumstances justified Brown’s very brief
    detention.
    The reasonableness of a detention involves both questions of fact and
    policy. Under Terry, we must balance “ ‘the need to search [or seize] against the
    invasion which the search [or seizure] entails.’ ” (Terry, 
    supra,
     392 U.S. at p. 21;
    accord, Glaser, 
    supra,
     11 Cal.4th at p. 363.) Police officers are required to make
    “swift, on-the-spot decisions” and the Fourth Amendment does not require us to
    “ ‘indulge in “unrealistic second-guessing” ’ ” of the officer’s conduct. (United
    States v. Sokolow (1989) 
    490 U.S. 1
    , 11 (Sokolow).)
    The reported crime was serious. It involved a violent fight between at least
    four people, one of whom claimed to have a loaded gun. Geasland arrived at the
    scene within three minutes of being dispatched and while the caller remained on
    the line. (See Dolly, 
    supra,
     40 Cal.4th at p. 468.) Brown was driving away from
    the location of the fight and was the only person in sight in the residential alley
    just after 10:30 p.m. The very recent report of a crime in progress, Brown’s close
    proximity to the crime scene, and the lack of other vehicle or pedestrian traffic in
    the residential alley are all significant factors. (See, e.g., People v. Conway (1994)
    17
    
    25 Cal.App.4th 385
    , 387-388, 390; People v. Lloyd (1992) 
    4 Cal.App.4th 724
    ,
    733-734.)5
    Deputy Geasland also attributed significance to the fact that Brown ignored
    the deputy’s attempt to question him about the fight and continued driving away
    from the scene. The deputy recounted that Brown drove directly past his marked
    patrol car in the “kind of tight” alley. Geasland rolled down his window and
    “yelled out” to defendant, “Hey. Did you see a fight?” Brown neither responded
    5        That the fight had ended does not affect the analysis in this case. In
    Hensley, 
    supra,
     
    469 U.S. 221
    , the court upheld a defendant’s detention 12 days
    after an armed robbery on the basis of a “ ‘wanted flyer.’ ” (Id. at p. 223.) In
    deciding whether reasonable suspicion could justify a detention for a “completed
    crime” (id. at p. 227), the court acknowledged that “[a] stop to investigate an
    already completed crime does not necessarily promote the interest of crime
    prevention” and that “the exigent circumstances which require a police officer to
    step in before a crime is committed or completed are not necessarily as pressing
    long afterwards. Public safety may be less threatened by a suspect in a past crime
    who now appears to be going about his lawful business than it is by a suspect who
    is currently in the process of violating the law.” (Id. at p. 228.) The court also
    observed that “officers making a stop to investigate past crimes may have a wider
    range of opportunity to choose the time and circumstances of the stop.” (Id. at pp.
    228-229.) Nonetheless, the court concluded that “[i]t is enough . . . if police have
    a reasonable suspicion, grounded in specific and articulable facts, that a person
    they encounter was involved in or is wanted in connection with a completed felony
    . . . .” (Id. at p. 229, italics added.) This crime was not “completed” in the sense
    that Hensley contemplated. The fight had ended only a minute or two before
    Geasland’s arrival, Brown was very near the scene, he was possibly armed, and
    there was not a “wide[] range of opportunity to choose the time and circumstances
    of the stop.” (Id. at pp. 228-229; cf. Dolly, supra, 40 Cal.4th at p. 466; see also 4
    LaFave, Search and Seizure (5th ed. 2012) § 9.2(a), pp. 373-374.)
    Brown argues that the crime involved here was a misdemeanor. We need
    not decide if his characterization is accurate, or under what circumstances, if any,
    the holding in Hensley extends to misdemeanor offenses. (Compare U.S. v. Grigg
    (9th Cir. 2007) 
    498 F.3d 1070
    , 1081, and U.S. v. Moran (10th Cir. 2007) 
    503 F.3d 1135
    , 1141 & fn. 4, with Gaddis v. Redford Township (6th Cir. 2004) 
    364 F.3d 763
    , 771, fn. 6.)
    18
    nor acknowledged the question. Geasland testified: “[w]hen he didn’t answer me,
    acknowledge me, or anything like that, I had a feeling he was involved.” The trial
    court did not rely on this circumstance, and neither do we. Geasland
    acknowledged that Brown may have simply failed to hear him and the trial court
    ultimately made no factual finding on that issue. Moreover, even if Brown
    ignored the deputy, a “ ‘refusal to cooperate [with law enforcement], without
    more, does not furnish the minimal level of objective justification needed for a
    detention or seizure.’ ” (Illinois v. Wardlow (2000) 
    528 U.S. 119
    , 125 (Wardlow);
    accord Bostick, 
    supra,
     501 U.S. at p. 437; Royer, 
    supra,
     460 U.S. at p. 498.)
    Notably, Geasland did not describe any behavior by Brown as they passed in the
    alley that could be construed as nervous or evasive. (Cf. United States v. Arvizu
    (2002) 
    534 U.S. 266
    , 270-271, 276-277 (Arvizu) [giving some weight to the fact
    that the defendant’s car slowed dramatically as he approached the officer; he
    stiffened and appeared to pretend the officer was not there, even though most
    drivers in that area “gave border patrol agents a friendly wave”; shortly thereafter,
    all of the children in the car put their hands up and began to waive mechanically at
    the officer “as if instructed to do so”].)
    Nonetheless, the fact that Brown drove away without responding left
    Geasland with no alternative short of a detention to identify him and determine if
    he had been involved in the fight. Notably, when Geasland turned around to
    follow Brown’s car, he found it parked on Georgia Street only a few houses down
    from the house behind which the fight had occurred. Brown’s decision to drive
    back towards the residence, along with the report of a possible weapon, provided
    an objective reason to suspect that he might present an ongoing danger to the
    19
    occupants of the house and the deputies who had responded to investigate. (Dolly,
    
    supra,
     40 Cal.4th at p. 466.)6
    Brown emphasizes that his conduct was consistent with lawful activity.
    However, “ ‘[t]he possibility of an innocent explanation does not deprive the
    officer of the capacity to entertain a reasonable suspicion of criminal conduct.’ ”
    (Souza, 
    supra,
     9 Cal.4th at p. 233, quoting In re Tony C., supra, 21 Cal.3d at
    p. 894; accord Arvizu, 
    supra,
     534 U.S. at p. 274; Wardlow, 
    supra,
     528 U.S. at
    p. 125; Sokolow, 
    supra,
     490 U.S. at p. 9.) “What is required is not the absence of
    innocent explanation, but the existence of ‘specific and articulable facts which,
    taken together with rational inferences from those facts, reasonably warrant that
    intrusion.’ ” (Glaser, 
    supra,
     11 Cal.4th at p. 373.) Although each of a series of
    acts may be “ ‘perhaps innocent in itself,’ ” taken together, they may “ ‘warrant[]
    further investigation.’ ” (Arvizu, at p. 274, quoting Terry, 
    supra,
     392 U.S. at
    p. 22.) The purpose of the detention is to resolve the ambiguity by allowing the
    officer to briefly investigate further. (Souza, at p. 233; Wardlow, at p. 125.)
    Moreover, it is significant that the detention preceding Geasland’s
    observations was exceptionally brief and nonintrusive. (Hensley, supra, 469 U.S.
    at p. 235 [examining, under Terry, both “the length and intrusiveness of the stop
    and detention”].) As noted in Glaser, 
    supra,
     11 Cal.4th at page 367, a detention’s
    “brevity weighs heavily in favor of a finding of reasonableness.” Geasland merely
    stopped his cruiser, flashed his emergency lights, and walked toward Brown’s car.
    When he was close enough to speak, he noticed several signs of Brown’s
    6      Although Geasland did not specifically mention this factor in his testimony,
    we look to the objective facts known to the deputy to determine whether the stop
    was reasonable under the circumstances. (Brigham City v. Stuart (2006) 
    547 U.S. 398
    , 404; People v. Letner and Tobin (2010) 
    50 Cal.4th 99
    , 145 (Letner).)
    20
    intoxication. Routine traffic detentions are considerably less intrusive than a
    search (Wells, 
    supra,
     38 Cal.4th at p. 1087), and here Brown had already stopped
    his car on his own. The deputy did not issue commands over a loudspeaker, draw
    a weapon, order Brown to step out of the car, or subject him to a pat-down search.
    But for the use of the emergency lights, the encounter would have been
    consensual.
    An officer “who lacks the precise level of information necessary for
    probable cause to arrest” is not constitutionally required to “simply shrug his
    shoulders and allow a crime to occur or a criminal to escape. On the contrary,
    Terry recognizes that it may be the essence of good police work to adopt an
    intermediate response. [Citation.] A brief stop of a suspicious individual, in order
    to determine his identity or to maintain the status quo momentarily while obtaining
    more information, may be most reasonable in light of the facts known to the
    officer at the time.” (Adams v. Williams (1972) 
    407 U.S. 143
    , 145-146; accord,
    Letner, 
    supra,
     50 Cal.4th at p. 149.)
    Here, a citizen living in a residential neighborhood made an emergency call
    seeking police assistance because a fight was happening in an alley behind the
    citizen’s home. The caller gave a specific address. The caller heard screaming
    and a reference to a loaded gun. The dispatcher heard screaming as well. The
    caller confirmed the fight was occurring as they spoke and remained on the line to
    narrate events.
    Within three minutes of dispatch Deputy Geasland arrived with lights and
    siren activated. Brown, the only person in the alley, was driving a car away from
    the reported location of the fight. It was after 10:30 p.m. Brown left the alley but
    drove back toward the scene on the main street. Under these circumstances, it was
    reasonable for Geasland to suspect the sole occupant of the alley may have been
    involved in the fight and to effectuate a brief and minimally intrusive detention,
    21
    which immediately yielded observations of criminal activity. The citizen who
    called for his help would surely hope the officer would do more to secure the
    safety of his neighborhood than shrug and drive away. (Adams v. Williams, 
    supra,
    407 U.S. at pp. 145-146; Wells, 
    supra,
     38 Cal.4th at p. 1083.)
