OPINION OF THE COURT
In this appeal arising under the Fourth Amendment, we consider whether Philadelphia police officers possessed sufficient reasonable articulable suspicion to stop a car. The traffic stop was based on information provided by a taxi driver who called 911 after he saw a man brandish a gun at a gas station. The District Court found that the 911 call did not provide police with reasonable suspicion to effectuate the traffic stop and, accordingly, suppressed the evidence gathered after the stop. Because we find that the totality of the circumstances amounted to reasonable suspicion, we will reverse.
I.
On February 22, 2005, at 2:59 p.m., the Philadelphia Police Department received a 911 call which included the following information:
CALLER: Heading to Philadelphia, Pennsylvania heading North on Broad at South Street. You got a guy with a BMW-742 or 51. License plate F Frank Victor Able 7726. Flashed a gun at the Hess station at a Bum [sic] trying to sell roses.
DISPATCHER: Heading North bound, you said?
CALLER: No, negative, he is now turned on South Street you got a cop right in front of him and I’m in back of him.
DISPATCHER: Alright give me the description of the male. Is he Black, White, or Hispanic Sir?
CALLER: He is Hispanic, 7451 Silver BMW, Frank Victor Able 7726 at 13 N. South heading towards the Delaware. You got a cop right in front of him and he is following the cop. I’m behind him in a green cab.
CALLER: He’s right in front of me. He has a 45, he had it in the console between the seats. He [took] it out and waved it at the bum selling roses at the Hess station. Your cop just turned right on 12th.
DISPATCHER: Ail right Sir.
CALLER: All right and he still, I’m behind him. I’m still on South Street just past 12th, *209 approaching 11th. I’m in a green Avenguard cab.
DISPATCHER: Okay, we got the job put out sir. All right, a Hispanic male that’s all you have?
CALLER: He’s at a red light now at 10th, I’m right behind him.
DISPATCHER: Sir, do not follow him, sir, the Police will be there as soon as possible. He’s heading Eastbound on South Street some one will be there sir.
CALLER: All right remember he’s got a 45 looks like a Glock in the center console. I was pumping gas at [sic] adjacent pump when he waved it at the bum. All right.
DISPATCHER: All right, Thanks.
CALLER: Your [sic ] welcome, I’m going to peel off.
At 3:02 p.m. — only three minutes after the 911 call was initiated — dispatch radioed officers on patrol and told them that a Hispanic male driving a silver BMW 745i with license plate FVA-7726 was driving eastbound on South Street, and that the driver had a gun.
Immediately upon receiving the report, officers in the field asked whether the dispatcher “got a complainant” for it; the dispatcher informed them that “no complainant is showing.” Within minutes, plainclothes officers observed a BMW 745i matching the dispatcher’s description and with license plate FVA-7726 pass them on South Street, approximately twelve blocks from where the taxi driver had initially reported it. Pursuant to department policy, the plainclothes officers relayed the information to uniformed police officers. By 3:07 p.m., uniformed officers spotted the vehicle, stopped it, and found that its driver — Defendant Johnny Torres, a Hispanic male — had a fully-loaded 9 millimeter handgun with one round in the chamber stowed in the pocket of the driver’s side door.
A grand jury indicted Torres on one count of possession of a firearm and ammunition by a convicted felon, in violation of 18 U.S.C. § 922(g)(1). Torres filed a motion to suppress the weapon and ammunition, arguing that the tip from the taxi driver did not supply reasonable suspicion for the stop. The District Court granted the motion to suppress after a hearing, and the Government appealed.
II.
The District Court had jurisdiction pursuant to 18 U.S.C. § 3231 and our jurisdiction arises under 18 U.S.C. § 3731. The Government argues that the District Court erred in suppressing the handgun and the ammunition. The parties agree that the decision to suppress turns on the question of whether the officers had a right to stop Torres’s vehicle pursuant to
Terry v. Ohio,
“In reviewing a suppression order, we exercise plenary review over the District Court’s legal conclusions, and we review the underlying factual findings for clear error.”
United States v. Laville,
III.
The Fourth Amendment prohibits “unreasonable searches and seizures.... ”
*210
U.S. Const, amend. IV. “Generally, for a seizure to be reasonable under the Fourth Amendment, it must be effectuated with a warrant based on probable cause.”
United States v. Robertson,
The initial step of a Fourth Amendment suppression analysis requires us to determine the timing of the seizure. “[U]nder
Terry,
in evaluating whether [the officer’s] interaction with [the defendant] prior to his arrest amounted to an unreasonable seizure, we must first determine at what moment [the defendant] was seized....”
Johnson,
Having pinpointed the time of the Fourth Amendment seizure, we next ask “whether that seizure was justified by reasonable, articulable facts known to [the officer] as of that time.... ”
Id.
When officers are told to investigate a situation by a police dispatcher, as was the case here, the court must look beyond the specific facts known to the officers on the scene to the facts known to the dispatcher.
See United States v. Nelson,
The Government concedes that the unidentified taxi driver’s tip was “the only information” known by the police when they seized Torres. When the Government relies upon a tip from an unidentified informant as the basis for reasonable suspicion, assessing the reasonableness of a
Terry
stop becomes more intricate.
See Adams v. Williams,
(1) The tip information was relayed from the informant to the officer in a face-to-face interaction such that the officer had an opportunity to appraise the witness’s credibility through observation.
(2) The person providing the tip can be held responsible if her allegations turn out to be fabricated.
(3) The content of the tip is not information that would be available to any observer ....
(4) The person providing the information has recently witnessed the alleged criminal activity.
(5) The tip predicts what will follow, as this provides police the means to test the informant’s knowledge or credibility
See Brown,
Here, having determined that Torres was seized for Fourth Amendment purposes at 3:07 p.m. when police stopped his vehicle, the District Court held that “the anonymous tip did not exhibit sufficient indicia of reliability to provide reasonable suspicion.” After noting that the tip did not contain “predictive information” or other “particularized knowledge,” and upon concluding that no other factors supported a finding of reasonable suspicion, the District Court granted Torres’s motion to suppress. The Government argues that the District Court “ignored substantial in-dicia of reliability.”
Considering the totality of the circumstances present in this case, we agree with the Government that the tip at issue possessed sufficient indicia of reliability to justify the stop of Torres’s vehicle. First, the tipster was an eyewitness who had “recently witnessed the alleged criminal activity.”
See Brown,
The aforementioned facts distinguish this tip from the anonymous one at issue in
Florida v. J.L.,
Finally, we note that the tipster neither attempted to, nor had any reason to, conceal his identity; the dispatcher simply neglected to ask him his name. As one of our sister circuits has stated: “[w]e do not fault the officers’ choice to forgo extensive credibility checking in order to quickly respond. The business of policemen and firemen is to
act,
not speculate or meditate on whether the report is correct. People could well die in emergencies if police tried to act with the calm deliberation associated with the judicial process.”
United States v. Sanchez,
To be sure, not all of the indicia of reliability we identified in
Brown
are present here. Nevertheless, although an anonymous tip without
any
indicia of reliability cannot justify a
Terry
stop,
see J.L.,
Here, the informant provided a detailed account of the crime he had witnessed seconds earlier, gave a clear account of the weapon and the vehicle used by Torres, and specified his own occupation, the kind and color of the car he was driving, and the name of his employer. The veracity and detail of this information were enhanced by the fact that the informant continued to follow Torres, providing a stream of information meant to assist officers in the field. Thus, the totality of the circumstances leads us to conclude that the taxi driver was an innominate
(i.e.,
unidentified) informant who could be found if his tip proved false rather than an anonymous (ie., unidentifiable) tipster who could lead the police astray without fear of accountability.
See Valentine,
Accordingly, we hold that the officers had reasonable articulable suspicion sufficient to justify a Terry stop and that the District Court erred in suppressing the fruits of that stop. We will reverse and remand for further proceedings consistent with this opinion.
