OPINION OF THE COURT
Kаhli Ubiles unlawfully possessed an unregistered firearm while attending a crowded street festival in St. Thomas. Acting on an anonymous tip that Ubiles possessed a gun, local authorities also in attendance stopped and frisked him. The authorities’ Terry search proved fruitful, and they seized the firearm and arrested him. The United States subsequently filed an indictment against Ubiles, who unsuccessfully moved to have the gun suppressed on the ground that it was seized unlawfully. A jury acquitted Ubiles of a federal charge and convicted him of the possession of an unregistered firearm, in violation of V.I. Code Ann. tit. 14, § 2253(a). This appeal followed.
Holding that the search and seizure of Ubiles was unlawful, we will reverse. The
“Terry”
stop in this case was not supported by reasonable suspicion “that criminal activity [was] afoot....”
Terry v. Ohio,
I.
The J’ouvert Carnival is a celebration that periodically takes place in the U.S. *215 Virgin Islands. The carnival сelebrates the sunrise, and hence begins before daybreak. J’ouvert festivities last until noon and are typically crowded and boisterous. Hundreds if not thousands of, revelers dance in the streets and march in a parade, while local bands lead the procession playing music from a flatbed truck. J’ou-vert celebrants often consume a great deal of alcohol.
Virgin Islands Territorial Court Deputy Marshal Franklin Leonard attended the April 30, 1998 J’ouvert Carnival on the Island of St. Thomas. He was off-duty at the time, and was joined by a female friend and two on-duty police officers, Virgin Islands Police Chief Amerieus Jackson and Virgin Islands Deputy Police Chief Jose Garcia. At approximately 9:00 a.m., an elderly gentleman approached Deputy Marshal Leonard and the officers. Without identifying himself, he told Leonard that there was a young man in the crowd standing on the sidewalk near the sea plane shuttle buildings who had a gun in his possession. The anonymous informant pointed toward the man in question and described his clothing and appearance. The informant did not explain how he knew that the man had a gun. He also did not describe, at the time, anything suspect about the gun or anything unusual or suspicious about the man or his behavior.
Deputy Marshal Leonard, followed by the two officers (but not the tipster), walked over to the young man — the defendant in this case — Kahli Ubiles. According to testimony elicited from Leonard at the suppression hearing, Ubiles exhibited no unusual or suspicious behavior when Leonard approached him or when Chief Jackson began talking to him. Leonard also testified that he could not tell when he approached Ubiles whethеr Ubiles was carrying any type of weapon. Leonard nevertheless conducted a pat-down search of Ubiles and found in Ubiles’s possession a cutlass (or machete) and a loaded gun. The firearm was a Jennings Long Rifle .22 caliber semi-automatic pistol, model J-22. The pistol’s serial number allegedly had been obliterated, and evidence adduced at Ubiles’s subsequent criminal trial revealed that the firearm was unregistered.
The United States subsequently charged Ubiles with possession of a firearm with an obliterated serial number in violation of federal law, 18 U.S.C. §§ 922(k), 924(a)(1)(B); possession of an unregistered firearm in violation of Virgin Islands law, V.I. Code Ann. tit. 14, § 2253(a); and escape from custody in violation of Virgin Islands law, V.I. Code Ann. tit. 14, § 661. A federal grand jury returned a three-count indictment on these charges. After the indictment was obtained, the Government sucсessfully moved to dismiss the escape from custody charge.
Before trial, Ubiles moved to suppress certain evidence, including the firearm seized by Deputy Marshal Leonard. At a hearing -on this motion, the Government presented no evidence suggesting that Leonard or Officers Jackson and Garcia knew anything about Ubiles other than the information with which the anonymous informant had provided them. Leonard stated that no one had told them anything that would lead them to believe (1) that Ubiles posed a danger to himself, the other officers, or the crowd; (2) that Ubiles had brandished the gun or machete in his possession; or (3) that Ubiles did not have a license to carry the gun in his possession. See App. at 71-73. Leonard testified merely that he was “very concerned about the situation” and therefore stopped and frisked Ubiles. Id. at 65.
Based on this tеstimony, the District Court denied Ubiles’s motion to suppress the J 22 seized from his person. In denying the motion to suppress the firearm, the District Court explained:
It’s the night of — I think I can take judicial notice of — can be some heavy drinking. People are tired.
So the kind of information that was given by the older gentleman to Marshal Leonard, that he had just — pointing out *216 the gentleman, describing the clothes that the defendant was wearing, had a gun, was enough reasonable suspicion for the law enforcement officers, the Chief Deputy, Chief, and Marshal Leonard to go over and question him in an investigative style. Prudent thing to do.
And certainly it turned out to be very prudent in this case for the officers’ protection while they were questioning the individual, to pat him down.
And that pat down produced [the J-22],
Id. at 104.
Ubiles’s case proceeded to trial. The Government introduced the J-22 into evidence and presented the testimony of Deputy Marshal Leonard; Brenda Mason, a Firearms Certification Officer with the U.S. Virgin Islands; and Ronald Lockhart, the anonymous informant (whose identity the Virgin Islands authorities had discovered shortly before trial). Leonard testified about seizing the weapon from Ubiles. Ms. Mason testified that after a thorough records search of St. Thomas and St. John files she had not found a firearm license for Ubiles’s gun. She also stated that the Firearms Certification Officer for the District of St. Croix had found no such record. Lockhart told the jury that at approximately 8:30 a.m., on April 30, he saw something that looked like a gun pass from another man to Ubiles. He testified that there were three to five minutes between the time he saw the gun and the time he spoke to the officers. However, Lockhart had not related these details tо the officers when he gave his tip. He had told Leonard only that he had observed a man with a gun and described and pointed to that man for the officers.
The jury found Ubiles not guilty of the federal charge — possessing a firearm with an obliterated serial number — but guilty of the territorial charge of possessing an unregistered firearm. Ubiles filed a post-trial motion to vacate the conviction, which was denied. The District Court sentenced Ubiles to three years imprisonment, suspending all but six months of the sentence, and to supervised probation for a period of four years and six months.

This appeal followed. The District Court of the Virgin Islands had jurisdiction under 18 U.S.C. §§ 3231, 3241, and 48 U.S.C.§ 1612(c). We have jurisdiction pursuant to 28 U.S.C. § 1291. We exercise plenary review of the District Court’s decision to deny Ubiles’s motion to suppress the firearm in question.

A reasonable suspicion of criminal activity may be formed by observing exclusively legal activity.

What remained the centerpiece of the Court’s analysis, however, was whether the defendant’s behavior pointed to the presence of illegal activity. Even though the officers’ suspicion was grounded in evidence of purely legal аctivity, the Court held that the stop was lawful only because the defendant’s behavior suggested that criminal activity was afoot.

Deputy Marshal Leonard and his compeers had no reason to believe that Ubiles was “involved in criminal activi-ty_”
Wardlow,

*218 L.Ed.2d 254 (2000) (rejecting an “automatic firearm exception” to the rule in Terry). Moreover, while there are ways to possess a gun illegally in the Territory — such as by possessing a gun with an altered serial number, see 18 U.S.C. § 922(k), or by possessing an unlicensed gun, see V.I. Code Ann. tit. 14, § 2253(a) — the Virgin Islands legislature has not enacted a criminal statute prohibiting gun possession in a crowd or at a carnival. During the suppression hearing the Government adduced no evidence suggesting that either Leonard or his officer confreres was aware of any articulable facts suggesting that the gun Ubiles possessed was defaced or unlicensed, that Ubiles posed a safety risk to the authorities or the J’ouvert celebrants, or that Ubiles was acting in a manner indicating that he was involved in a different crime. For all the officers knew, even assuming the reliability of the tip that Ubiles possessed a gun, Ubiles was another celebrant lawfully exercising his right under Virgin Islands law to possess a gun in public. That is as much as Lockhart told Leonard and Officers Jackson and Garcia in pointing to Ubiles and informing them that Ubiles had a gun in his possession.
This situation is no different than if Lockhart had told the officers that Ubiles possessed a wallet, a perfectly legal act in the Virgin Islands, and the authorities had stopped him for this reason. Though a search of that wallet may have revealed counterfeit bills — the pоssession of which is a crime under United States law,
see
18 U.S.C. §§ 471-72-the officers would have had no justification to stop Ubiles based merely on information that he possessed a wallet, and the seized bills would have to be suppressed. The District Court’s rationale for not suppressing the firearm in this case is troubling, therefore, insofar as it seems to endorse the stop based on the fruits obtained as a result of the subsequent search.
See
Part I (reproducing the District Court’s rationale). This post-hoc justification for stops and searches has been repeatedly rejected.
See, e.g., Florida v. J.L.,
— U.S.-,-,
As with the case of the hypothetical wallet holder, the authorities here had no reason to know that Ubiles’s gun was unregistered оr that the serial number had been altered. Moreover, they did not testify that it is common for people who carry guns in crowds — or crowds of drunken people — to either alter or fail to register their guns, or to use them to commit further crimes — all of which would be additional evidence giving rise to the inference that Ubiles may have illegally possessed his gun or that criminal activity was afoot. Therefore, as with thе wallet holder, the authorities in this case had no reason to believe that Ubiles was engaged in or planning or preparing to engage in illegal activity due to his possession of a gun. Accordingly, in stopping him and subsequently searching him, the authorities infringed on Ubiles’s Fourth Amendment rights.
Lockhart’s in-court testimony during Ubiles’s trial does not undermine this conclusion. Lockhart testified at trial about how he saw Ubiles come to possеss the gun. He stated that another man surreptitiously handed the gun to Ubiles, and that Ubiles slipped the gun into his pocket. The nature of this exchange could give rise to the inference that Ubiles was not the gun’s owner. One could further infer based on this original inference, that, because Ubiles was not the gun’s owner, he illegally possessed the gun, for it is illegal to possess a gun in the Virgin Islands that is not registered in your own name. See V.I. Codе Ann. tit. 14, § 2253(a); V.I. Code Ann. tit. 23, § 470. But there was no testimony introduced at the suppression hearing that Lockhart had told Leonard,
before the search,
that another man had surreptitiously handed the gun to Ubiles. As noted above, “[t]he

reasonableness of official suspicion must be measured by what the officers knew

they conducted their, search,”

Nor can the Government rely on the fact that this stop took place during a crowded festival to make up for the lack of reasonable suspicion present in this case. We decline the Government’s invitation to extend to crowds generally the Supreme Court’s relaxed search and seizure jurisprudence dealing with close quarters, and the special risks attendant thеreto, in airports and schools. In Florida v. J.L., the Supreme Court opined:
The facts of [Florida v. J.L.] do not require us to speculate about the circumstances under which the danger alleged in an anonymous tip might be so great as to justify a search even without a showing of reliability. We do not say, for example, .... that public safety officials in quarters where the reasonable expectation of Fourth Amendment privacy is diminished, such as airports, see Florida v. Rodriguez,469 U.S. 1 ,105 S.Ct. 308 ,83 L.Ed.2d 165 (1984) (per curiam), and schools, see New Jersey v. T.L.O.,469 U.S. 325 ,105 S.Ct. 733 ,83 L.Ed.2d 720 (1985), cannot conduсt protective searches on the basis of information insufficient to justify searches elsewhere.
— U.S. at-,
We believe that neither the heightened safety concerns observed at airports, nor the pedagogical and safety concerns implicated at schools obtain any time a crowd of adults congregates. If that were not the case, citizens farming under the open skies of Washington or Vermont would generally have greater Fourth Amendment protections than their compatriots bustling to work in Manhattan or Boston. As a general proposition of constitutional law, this cannot be so; Terry applies equally in each of these locales.
A California court of intermediate appeals reached a similar conclusion on similar facts:
This court believes that the fact that respondent was in a [crowded] public [street] close to [presidential candidate] Gary Hart is not relevant under the circumstances of this case to the issue of whether respondent had a legitimate expectation of privacy....
“[T]he Fourth Amendment’s protections against unreasonable seizure of effects upon the person remains fully applicable.” ( [Oliver v. United States,466 U.S. 170 , 179,104 S.Ct. 1735 ,80 L.Ed.2d 214 (1984) ].) “[T]he Fourth Amendment protects people — and not simply ‘areas’ — against unreasonable searches and seizures.” (Katz v. United States, [389 U.S. 347 , 353,88 S.Ct. 507 ,19 L.Ed.2d 576 (1967) ] ). “Unquestionably petitioner was entitled to the protection of the Fourth Amendment as he walked down the street in Cleveland.” (Terry v. Ohio,392 U.S. 1 , 9,88 S.Ct. 1868 ,20 L.Ed.2d 889 (1968)).
People v. Carlson,

For the foregoing reasons, the judgment of the District Court will be reversed. The firearm seized from Ubiles should have been suppressed as the fruit of an unlawful seizure.
Notes
. Our
Terry
holding obviates the need to reach several other important questions inhering in this case. First, because of our
Terry
holding, we are able to assume
arguendo
that the informant’s tip in this case was reliable, and therefore, we need not grapple with the fact that the Virgin Islands authorities relied on a face-to-face anonymous tip to stop and frisk Ubiles.
Cf. Florida v.
J.L., - U.S. -,-,
. We note that the District Court ordered that Ubiles’s term of imprisonment be served consecutive to an unrelated criminal charge on which the Virgin Islands authorities were holding Ubiles. The Virgin Islands statute governing consecutive sentences for the violation of territorial statutes allows for the imposition of sentences "to be served ... conseсutively to any other sentence imposed at the same time or prior thereto.” V.I. Code Ann. tit. 5, § 3672(a) (2000) (emphasis added). Section 3672(a) does not speak of the imposition of sentences "to be served consecutively to any other charge brought at the same time or prior thereto,” nor would it seem appropriate to do so. Until a charge matures into a conviction and then a sentence, a suspect held on that charge is a mere detainee, and not a prisoner of the state serving a sentence in addition to which another sentence could be imposed consecutively. Therefore, the sentence in this case commenced as soon as it was imposed, on February 4, 2000. The sentence accordingly expired on August 4, 2000. However, inasmuch as the non-jail portion of the sentence remains, this appeal is not moot.
. In engaging in the analysis in the three paragraphs above, we intimate no view as to whether this additional hypothetical information would have been sufficient to warrant a finding of reasonable suspicion. The information would represent additional evidence (weighing in favor of a finding of reasonable suspicion) in " ‘the totality of the circumstances’ ” a court must consider in determining whether a stop was reasonable.
