A jury found appellant Gary E. Smith, Jr. guilty of possession with intent to distribute PCP, D.C.Code § 33-541(a)(l) (1993 Repl.), and possession with intent to distribute marijuana, id § 33-541(a)(l). The jury found appellant Herman R. Speight guilty of possession with intent to distribute PCP while armed, id §§ 33-541(a)(l), 22-3202 (1989 Repl.); possession with intent to distribute marijuana, id § 33-541(a) (1989 Repl.); possession of an unregistered machine gun, id § 6-2311(a) (1989 Repl.); possession of an unregistered pistol, id § 6-2311(a); two counts of possession of ammunition, id § 6-2361(3) (1989 Repl.); and possession of a firearm during a crime of violence or dangerous offense, id § 22-3204(b) (1989 Repl.). Appellants argue on appeal that the trial court erred by denying their respective (1) motions to suppress and (2) motions for judgment of acquittal based on insufficient evidence of constructive possession of the drugs and weapons found in the automobile they were near when arrested. We affirm.
I.
On February 5, 1993, at approximately 9:30 p.m., an anonymous caller informed police about a man with a gun in the area of 11th Street and Park Road, N.W. The caller described two black males, one wearing a white cap, jeans, and a red hooded sweatshirt, and the other wearing jeans, a black coat with fur around the collar, and a black cap. The caller said the two suspects had placed guns and drugs in a blue Dodge Aspen, with a given license plate number, parked near the San Miguel restaurant in the 3300 block of 11th Street.
Officers William Witkowski and Darryl Green arrived on the scene within two or three minutes of receiving the caller’s information radioed to them in their patrol car nearby. As the officers approached the 3300 block of 11th Street, they saw a blue Dodge Aspen with a license plate number that matched the tag number described over the police radio. The officers then saw two men walking across the street from the 3300 block to the 3400 block of 11th Street. One of the men, later identified as Smith, was wearing a white cap, jeans, a red hooded sweatshirt, and a black jacket over the sweatshirt; the other, later identified as Speight, was wearing jeans, a black coat with fur around the collar, and a black cap. Although the officers observed a few other persons nearby, no one else in the area at that time wore clothing that matched the anonymous caller’s descriptions.
When the officers first saw appellants, Smith was walking approximately five to ten feet in front of Speight as the two crossed the street. As the uniformed officers ap *445 proached appellants in a marked police car, Smith continued walking north and entered a nearby convenience store, while Speight remained near 11th and Park Road where the police had first observed him. The officers stopped both appellants and brought them together in the middle of the block.
Officer Witkowski, who performed a protective pat-down of Smith, felt keys in Smith’s pants pocket but discovered no drugs or weapons during the frisk. In stopping Speight, Officer Green learned Speight’s name, address, and Social Security number but, during a frisk, found no drugs or weapons. Officer Dino MePadden, also responding to the radio broadcast, then arrived and informed Officer Witkowski that a WALES check on the Dodge Aspen revealed that Speight was the registered owner. Officer Witkowski learned that the frisk of Speight did not yield any ear keys, so Witkowski asked Smith whether he had any keys. When Smith replied that he did not, Witkow-ski reached into Smith’s pocket and removed a set of keys.
Officer Witkowski recognized that the keys belonged to a Chrysler or Dodge vehicle and, with Green, walked over to the Dodge Aspen about a block away. As the officers began to examine the outside of the ear, they smelled the odor of PCP emanating from the partially open passenger side window. The officers opened the ear with the keys seized from Smith’s pocket.
Under the car’s front seat the officers discovered an opaque GAP shopping bag containing 23 plastic heat-sealed bags, each of which (according to later tests) contained marijuana laced with PCP. In the center console of the vehicle, the police found a plastic container with a fully-loaded .38 caliber revolver and a fully-loaded magazine for a semiautomatic weapon. In the trunk the officers discovered a Gloek .9-millimeter semiautomatic handgun, a gallon-size glass jar that smelled of PCP, and a box of heat-sealable sandwich bags. The officers then informed Speight and Smith that they were under arrest.
While Speight was on his way to the police station, he asked the officer “who had called him in.” Upon arriving at the police station, Speight told the officer that he knew who had snitched on him because he had seen the person “call[] him in on the pay phone.”
When Smith arrived at the police station, he asked an officer what he was charged with doing. The officer replied with the charges against him, whereupon Smith responded, “There ain’t no way I can beat this shit, can I?”
II.
We first consider appellants’ contention that the trial judge erred in denying their respective motions to suppress evidence. In order to determine the admissibility of the drugs and weapons found in the Dodge Aspen, we initially must evaluate whether the police had a reasonable, articulable suspicion justifying the initial stop under
Terry v. Ohio,
Second, we address the scope of the frisk. We conclude that the seizure of the keys from Smith’s pocket exceeded the scope of a permissible Terry frisk because, at the time the keys were seized, the officer did not have reason to believe they were a weapon or contraband. The fact that Smith had the keys to the car, therefore, could not lawfully contribute to establishing probable cause to support the officers’ search of the ear. We also conclude, however, that Smith’s possession of the car keys was evidence admissible at trial because the keys inevitably would have been discovered incident to appellants’ subsequent, lawful arrest.
Third, we consider whether the Fourth Amendment allows the police to conduct a warrantless search of a vehicle lawfully parked on a public street when there is probable cause to believe the vehicle contains weapons and contraband. We conclude that the officers legally may search such a vehicle based on probable cause without a warrant, *446 and that, in this case, the information lawfully available to the officers at the time they searched the Dodge Aspen constituted probable cause.
Finally, we conclude that the combination of a corroborated, detailed, anonymous tip, when coupled with the discovery of weapons and illegal drugs in the car, gave the police probable cause to arrest appellants, without consideration of the illegally seized keys. We therefore affirm the trial court’s denial of appellants’ motions to suppress the physical evidence.
A. Reasonable Suspicion Justifying a Terry Stop
The question whether the officers had reasonable suspicion justifying a
Terry
stop is a mixed question of fact and law. On appeal, this court accepts the trial court’s factual findings unless they are clearly erroneous but makes an independent legal conclusion as to whether there was reasonable suspicion for the stop.
See Cauthen v. United States,
A police officer must have a reasonable, articulable suspicion that criminal activity is afoot before that officer lawfully can stop (or seize) an individual without that person’s consent.
See Terry,
We have upheld
Terry
seizures in previous cases when the content of the information the police acquired was equal to, or less than, the information the officers had here.
See, e.g., Turner v. United States,
Appellants argue that these prior cases are distinguishable from the present case because the informants there were not anonymous; the callers either were known to be reliable because they were working with the police, or they presumably were reliable because they apparently were eyewitness callers.
See Cauthen,
This case, therefore, presents us with the kind of detailed information commonly used to justify a lawful
Terry
stop, but the anonymous source of the information presents a problem: whether, considering the combined “content of information possessed by police and its degree of reliability,” the police possessed reasonable suspicion, under the totality of the circumstances, to stop the suspects.
See White,
In
White,
the Supreme Court recognized that an otherwise unreliable tip gains reliability once it is corroborated, but the Court stressed that, to demonstrate the tip’s reliability, the corroborating information should be information other than “easüy obtained facts and conditions existing at the time of the tip.”
Id.
at 332,
After
White,
this court in both
Cauthen,
There are significant differences, however, between the present ease and our decisions in
Cauthen
and
Brown.
In
Cauthen,
there was no physical description of the individuals involved, and the police did not arrive at the scene until at least fifteen minutes after the
*448
radio broadcast.
See Cauthen,
We further distinguish this case from
Cau-then
and
Brown
because the anonymous tip here, unlike the tips in
Cauthen
and in
Brown,
implicated a risk to public safety by alerting police that the individuals described had access to a gun.
3
Fourth Amendment
Terry
stop analysis balances the “need to search or seize against the invasion which the search or seizure entails.”
Michigan v. Long,
Although this is a close case, we believe the report that an individual was armed— potentially implicating the safety of both police officers and the public — combined with the officers’ corroboration of an extremely detailed description minutes after hearing the radio broadcast, justified the intrusion involved in briefly detaining and frisking appellants. 4
B. Permissible Scope of the Terry Stop; Seizure of the Car Keys from Smith
Appellants argue next that, even if the police had reasonable suspicion to stop and *449 frisk them, the detention exceeded the permissible scope of a lawful Terry stop. They say that the police should have told them they were free to leave when the initial frisks revealed no evidence of criminal activity. Smith further contends that the police unlawfully seized the keys to the Dodge Aspen from his pocket since that seizure exceeded the scope of a lawful Terry frisk.
Once police make a lawful
Terry
stop, they may reasonably detain the suspect while conducting further investigation.
See Turner,
Here, after the fiisks yielded no weapons or contraband, appellants were detained for a few minutes while police investigated the Dodge Aspen and, as elaborated below, promptly established probable cause to arrest them both.
See Franklin v. United States,
We turn to Smith’s contention that the police unlawfully seized the keys to Speight’s Dodge Aspen from Smith’s pocket during the
Terry
stop. The purpose of a
Terry
frisk is to ensure the safety of police officers by allowing a limited patdown of a stopped suspect to check for weapons.
See Minnesota v. Dickerson,
C. Warrantless Seizure of Guns and Drugs from the Car Based on Probable Cause: The Automobile Exception
The next question is whether the police acted lawfully when they proceeded to search Speight’s car without obtaining a warrant.
5
The Fourth Amendment protects “the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” U.S. Const, amend. IV. In the interests of protecting this fundamental right, the Supreme Court has interpreted the Constitution to incorporate a general rule “that searches and seizures be conducted pursuant to a warrant issued by an independent judicial officer.”
California v. Carney,
The Supreme Court announced the automobile exception in
Carroll v. United States,
if the search and seizure without a warrant are made upon probable cause, that is, upon a belief, reasonably arising out of circumstances known to the seizing officer, that an automobile or other vehicle contains that which by law is subject to seizure and destruction, the search and seizure are valid.
Id.
at 149,
The Supreme Court’s original justification for the automobile exception focused on the mobility of motor vehicles.
See Preston v. United States,
Throughout this line of “automobile exception” eases justifying warrantless searches, the Supreme Court has recognized that the Fourth Amendment requires courts to weigh the need for public safety against the protection of privacy interests. In particular, the Court has repeatedly relied on the potential presence of weapons in determining the legality of vehicle searches.
See, e.g., Michigan v. Long,
a warrantless search of an automobile towed to a private garage even though no probable cause existed to believe that the vehicle contained fruits of a crime. The sole justification for the warrantless intrusion was that it was incident to the care-taking function of the local police to protect the community’s safety. Indeed, the protective search was instituted solely because local police “were under the impression” that the incapacitated driver, a Chicago police officer, was required to carry his service revolver at all times; the police had reasonable grounds to believe a weapon might be in the car, and thus available to vandals.
Opperman,
The Supreme Court has not yet addressed the question presented here: whether the police may conduct a warrantless search of an unoccupied, operable vehicle lawfully parked on a public street based on probable cause to believe the vehicle contains evidence of a crime.
7
A number of federal circuit courts of appeals, however, recently have sustained such searches.
8
See United States
*452
v. Reed,
The principles established in the Supreme Court’s “automobile exception” cases, as applied to the facts here, dictate the result here; they demonstrate that the police acted reasonably, based on probable cause without need for a warrant, when searching the Dodge Aspen. First, the police were faced with exigent circumstances.
10
The Dodge Aspen was parked on a public street and appeared capable of being driven away at any moment. Although the police had detained Speight and Smith, nothing prevented confederates or adversaries from gaining access to the car.
See Thomas,
*453 For constitutional purposes, we see no difference between on the one hand seizing and holding a car before presenting the probable cause issue to a magistrate and on the other hand carrying out an immediate search without a warrant. Given probable cause to search, either course is reasonable under the Fourth Amendment.
Id.
at 52,
Having concluded that the police may conduct a warrantless search of an apparently functional vehicle parked on a public street if they have probable cause that the vehicle contains weapons, we now consider whether the police here had such probable cause.
We note, initially, that the police invaded no privacy interest by approaching a vehicle parked on a public street and smelling the air emanating from the vehicle. An individual has a reasonable expectation of privacy in property only when manifesting a subjective expectation of privacy that society accepts as objectively reasonable.
See California v. Greenwood,
The smell of PCP emanating from the car partially corroborated the anonymous tip. The smell of PCP not only gave the police probable cause to believe that an additional fact alleged in the tip was true,
see Minnick v. United States,
In sum, the combination of the informant’s detailed tip — now partially corroborated by inside information — the report of weapons in the car, and the smell of PCP emanating from the car gave the police probable cause to believe that the blue Dodge Aspen contained contraband. The trial court, therefore, did not err in denying appellants’ motions to suppress the guns and drugs evidence obtained from the search of the Dodge Aspen.
D. Probable Cause to Arrest
During the Terry stop, police officers learned Speight’s identity and determined that Speight owned the Dodge Aspen that *454 later was discovered to contain guns and drugs. The police also discovered the keys to the Aspen in Smith’s pocket, although we already have noted that this seizure was unlawful and thus could not contribute to a finding of probable cause to search the vehicle or to arrest Smith. See supra Part II.B.
Once, however, the police lawfully discovered drugs and weapons in the car — which they had probable cause to search without reference to the keys found on Smith — the anonymous callers’ detailed tip gained substantially greater indicia of reliability. The fact that the caller accurately predicted drugs and weapons would be found in the car indicated that the caller had inside information. A detailed tip from a reliable informant may provide police with probable cause to arrest the described suspects — which was the case here.
See Hill v. United States,
Even without regard to the keys connecting Smith to Speight’s car, therefore, the police had enough information from the tip, coupled with Smith’s presence in the vicinity of the car, to justify his arrest, as well as Speight’s arrest, based on probable cause. 13
Once Smith was lawfully arrested, the police could have lawfully searched his person incident to that arrest. At that time, the police inevitably would have discovered in Smith’s pocket the keys to Speight’s car. Accordingly, although the police had illegally seized those keys from Smith too early, during the period of detention justified only by
Terry,
that premature seizure did not preclude admission of the keys in evidence at Smith’s trial, because the eventual probable cause to arrest, under the circumstances here, erased the illegality.
See District of Columbia v. M.M.,
III.
Appellants contend, finally, that the trial court erred in denying their motions for judgment of acquittal, claiming the evidence was insufficient to support a finding that they possessed the drugs and weapons police discovered some distance away in the Dodge Aspen.
We recently explained the standards governing a motion for judgment of acquittal:
In ruling on a motion for judgment of acquittal alleging insufficiency of the evidence, the trial court must review the evidence in the light most favorable to the government. Curry v. United States,520 A.2d 255 , 263 (D.C.1987). If a reasonable juror, evaluating that evidence and drawing permissible inferences therefrom with *455 out engaging in conjecture or speculation, must have some reasonable doubt as to the existence of any essential element, the motion should be granted. Id.; McClain v. United States,460 A.2d 562 , 567 (D.C. 1983). This court “employs the same standard as that applied by the trial court in determining whether the evidence was sufficient to convict.” Curry, supra,520 A.2d at 263 .
McKinnon v. United States,
In this case, the government proceeded under a theory of constructive possession. “To establish constructive possession, the government must prove that the accused (1) knew the location of the [contraband], (2) had the ability to exercise dominion and control over [it], and (3) intended to exercise such dominion and control.”
Earle v. United States,
As to the second factor, the record shows that both appellants had the ability to exercise dominion and control over the contents of the vehicle. The police discovered that Speight was the registered owner of the vehicle and that Smith possessed the keys to it.
Finally, there was evidence that appellants intended to exercise dominion and control over the guns and drugs. Their respective incriminating statements “indieate[d] consciousness of guilt.”
See (James) Speight v. United States,
[[Image here]]
The trial court did not err in admitting the evidence presented at trial, and the evidence sufficiently supported appellant’s convictions.
Affirmed.
Notes
. We previously had observed that “[t]his court on many occasions, in widely varied factual settings, has upheld stops and protective frisks based entirely on information provided by anonymous citizens.”
Allen v. United States,
. In
United States v. (Morris) Johnson,
. At oral argument, appellants' counsel noted that an anonymous tip may be prompted by a wide variety of motives.
See Brown,
.Holston v. United States, 633
A.2d 378 (D.C. 1995), concerned an anonymous tip that a man with a gun was holding a woman at bay near a bronze BMW with a specific license number at a particular location. Police arriving at the scene approximately 15 seconds after the radio broadcast “observed a man bending over into the trunk of an automobile which matched precisely the description given.”
Id.
at 382. The man "appeared to be putting something in the trunk, reacted with a startled look, slammed the trunk down and walked away.”
Id.
In
Holston,
we intimated that the appellant’s furtive gestures corroborated a tip that might otherwise have been inadequate.
See id.
at 382-83. Despite the lack of furtive gestures in the present case, however, we conclude that the totality of the circumstances supports the reasonableness of the stop.
See Gomez v. United States,
. The government does not challenge the trial court’s assumption that Smith has standing to challenge the seizure of contraband from the car, and we therefore assume without deciding that Smith can properly challenge the admissibility of evidence seized from the car.
See In re C.A.P.,
. As a result of the shift in rationale for exception to the warrant requirement from exigent circumstances reflected in vehicular mobility to the lesser expectation of privacy in regulated, relatively open vehicles, the Supreme Court has upheld warrantless inventory searches of vehicles and containers inside vehicles conducted after the vehicles had been impounded in police custody.
See Chambers v. Maroney,
the justification to conduct such a warrantless search does not vanish once the car has been immobilized; nor does it depend upon a reviewing court’s assessment of the likelihood in each particular case that the car would have been driven away, or that its contents would have been tampered with, during the period required for the police to obtain a warrant.
Id.
at 261,
. Language employed by the Supreme Court— although deciding issues distinct from the question presented here — is sufficiently broad, based on differing rationales, to encompass our ruling today.
See Carney, All
U.S. at 394,
. Cases from this court, taken together, do not provide a clear constitutional ruling on whether a warrant is required before the police may search an unoccupied vehicle parked in a public place. In
Shreeves
v.
United States,
. The present case does not require us to decide, and we express no opinion on the question, whether the Fourth Amendment requires the police to obtain a warrant to search a vehicle of any kind parked on private property.
See Shreeves,
. We reiterate that the Supreme Court, in developing some aspects of the automobile exception, has said that the inherent mobility of automobiles created exigent circumstances, and that the Court, when developing other aspects of the automobile exception, has noted that the Fourth Amendment does not require exigent circumstances to uphold a warrantless automobile search.
Compare Opperman,
.Officer Witkowski listed the presence of weapons as one of the considerations he relied on in deciding not to seek a warrant. When the court asked the officer why he did not obtain a warrant to search the car, he candidly replied:
Quite frankly, Your Honor, I thought we had enough, with all the pieces of the puzzle, to meet probable cause. We had the defendants that matched the lookout. We had the vehicle where it belonged. The vehicle had the same license plate number.... Plus, there was weapons involved. At the time, I felt it was best to just go ahead.
. The fact that the police used the keys illegally recovered from Smith to open the car is of no consequence. Upon establishing probable cause to search the car, the police were justified in opening the car by any reasonable means — and certainly would have opened the car — even if they had not improperly seized the keys.
.
United States v. (Gerald) Lewis,
. The trial court excluded evidence regarding the content of the information in the police "lookout” on hearsay grounds. No evidence was presented at trial that an anonymous caller informed police that the appellants had placed guns and drugs in the Dodge Aspen.
. Although appellants do not explicitly raise the point, we note that the evidence was also sufficient for the jury to infer the intent to distribute. See Earle, 612 A.2d at 1270 (upholding conviction for possession with intent to distribute when drugs and paraphernalia were packaged in a manner consistent with distribution, in amounts regularly sold and purchased on the street).
