The United States appeals from a district court order granting defendant Raymond Johnson’s motion to suppress a pistol seized from him by an Albuquerque police officer. We exercise jurisdiction pursuant to 18 U.S.C. § 3731 and 28 U.S.C. § 1291, reverse the district court’s order, and remand for further proceedings.
Background
On October 24, 2002, Albuquerque Police (“APD”) received a call from a citizen say *1187 ing he had just seen a middle-aged man forcing a pre-teen girl to walk down Copper and Pennsylvania Avenues in a part of town known to police as the “War Zone” for its high levels of violent crime. The caller said he was still observing the pair and described their actions and appearance in detail, noting that the man appeared to be pushing and yelling at the girl and looking around for something, but that he did not see any weapons. The caller promptly gave police his cell phone number when asked and forthrightly answered all of the dispatcher’s questions. He stayed on the line for approximately eight minutes, until he saw a marked police cruiser approach the pair.
The cruiser belonged to Officer Robert Middleton, who had heard the dispatcher’s report of the incident on his poliсe radio. The dispatcher had requested that officers investigate a suspicious person, and classified the call as Priority 2. Priority 2 calls are the second-highest category in the. APD’s priority system, below emergencies requiring immediate response but above those which can wait for an hour or more. The dispatcher described a black male adult forcing a white female juvenile to walk southbound on Pennsylvania and described the man as approximately 35 years old, five feet, nine inches tall, with short, curly hair, wearing green jeans and a white jacket with red “USA” lettering. The dispatсher described the girl as around 12 years old, wearing a green hooded jacket and blue jeans, approximately 90 pounds, and the same height as the man. The dispatch information, which was also displayed on a computer screen in Officer Middleton’s vehicle, indicated that it was unknown whether the man was intoxicated or armed.
Minutes after receiving the' call, Officer Middleton drove down Pennsylvania Avenue and saw a man and girl matching the descriptions given by the caller and relayed by the dispatcher. The only difference in their appearance was the girl’s height, which the caller had estimated as five feet, four inches, but which the dispatcher mistakenly had listed as five feet, nine inches. Officer Middleton briefly watched the pair and testified that he did not observe the man push or otherwise threaten the girl. He then pulled his marked cruiser next to the pair, got out and identified himself. The man was later identified as the defendant and the girl as Samantha D. 1
Officer Middleton told the pair about the call and asked if the girl was “okay.” Samantha said she was, and both she and Johnson denied that anything untoward had happened. Officer Middleton testified that the girl did not appear injured or upsеt. According to Officer Middleton, however, Johnson was acting “fidgety” and looking back and forth. Johnson was also repeatedly pressing the transmission button on a walkie-talkie he was carrying, though he did not put it to his mouth and speak directly into it.
Just after Officer Middleton approached the pair, another officer, Rob Duren, arrived. Officer. Middleton asked Officer Dpren to question the girl while he talked to Johnson separately. Johnson and Officer Middleton then walked a few steps to the front of Officer Middleton’s car, and *1188 Officer Middleton asked Johnson to put down the walkie-talkie. Johnson did sо.
Officer Middleton testified that he was concerned that Johnson may have kidnapped the girl, or that the two were involved in prostitution. Officer Middleton knew that prostitution and drug dealing were prevalent in the “War Zone,” and that drug dealers and other criminals often used walkie-talkies to signal each other to police presence or possibly to call in attackers. Officer Middleton himself had previously been involved in a shooting in the area.
Once they were alone, Officer Middleton asked to see Johnson’s identification. Johnson handed over an ID card or his wallet, which the officer either put on the hood of his car or held in his hand. Officer Middleton then said, “I’m going to pat you down for weapons.” Johnson immediately told the officer that he had a gun and gestured to his right side. Officer Middleton told Johnson to turn away from him, pulled Johnson’s jacket aside, and retrieved a .22 caliber pistol from Johnson’s belt. Officer Middleton then handcuffed Johnson.
Officer Middleton testified that Johnson was compliant, never made any threatening movements or remarks, and indeed acted “like a gentleman” during the three minutes between their initial meeting and the discovery of the weapon.
On Novеmber 15, 2002, a federal grand jury indicted Johnson on the sole count of being a felon in possession of a firearm, in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). In response, Johnson filed a motion to suppress the pistol. After conducting an evidentiary hearing, the district court granted Johnson’s motion. This appeal followed.
Discussion
In its order, the district court gave three reasons for suppressing the weapon: (1) the anonymous call to police “was insufficient to provide reasonable suspicion for the initial stop,” (2) even if the initial stop was permissible any “reasonable suspicion was dispelled by Officer Middleton’s initial contact with Defendant and Samantha,” and (3) “the pat-down search ... was not based on a reasonable suspicion that Defendant was armed and dangerous, and was conducted after any possible reasonable suspicion of criminal activity had been dispelled.” On appeal, we view the evidence in the light most favorable to the prevailing party and review the district court’s findings of fact only for clear error.
United States v. De la Cruz-Tapia,
I.
As we have recognized before, police-citizen encounters come in three varieties.
The first involves the voluntary cooperation of a citizen in response to non-coercive questioning. The second is a Terry v. Ohio,392 U.S. 1 ,88 S.Ct. 1868 ,20 L.Ed.2d 889 (1968), stop, involving only a brief, non-intrusive detention and frisk for weapons when officers have a reasonable suspicion that the defendant has committed a crime or is about to do so. The third encounter is the arrest of the defendant.
United States v. Madrid,
“The Fourth Amendment proscribes unreasonable searches and seizures; it does not proscribe voluntary cooperation.”
Florida v. Bostick,
The parties disagree about precisely when Johnson’s participation became involuntary, thus implicating the Fourth Amendment. Though it is debatable whether the relevant aspects of the encounter ever moved beyond voluntary cooperation, the government has conceded that a seizure occurred when Officer Middleton took Johnson’s identification. Johnson claims it was a few moments earlier, when Officer Middleton asked him to put down the walkie-talkie. Because we conclude Officer Middleton had reasonable suspicion both when he asked Johnson to put down the walkie-talkie and when he asked for Johnson’s identification, we need not determine the precise moment when a seizure occurred and will assume, without deciding, that the “inception of the detention” coincided with Officer Middleton’s request that Johnson put down the walkie-talkie.
For our purposes, then, we simply note that after separating Johnson and Samantha, Officer Middleton did four things in rapid succession: First he asked Johnson to put down the walkie-talkie. Next, he took Johnson’s identification. Then he told Johnson he was going to pаt him down for weapons. Finally, after Johnson said he was carrying a gun, Officer Middleton reached under Johnson’s jacket and removed the pistol. These actions, taken together, constitute the detention and weapons search whose reasonableness we must decide.
II.
Terry
sets up a two-prong test of the reasonableness of investigatory detentions and weapons searches.
See Gallegos v. City of Colorado Springs,
A.
We agree with the government that the district court’s order impermissibly “evaluate[d] and rejected] each factor in isolation” and failed to accord proper deference to the judgment of an experienced officer.
See United States v. Gandara-Salinas,
1. The Tip
The district court first addressed whether the anonymous call alone was sufficient to give Officer Middleton reasonable suspicion. The court relied heavily on
Florida v. J.L.,
The purpose of the Fourth Amendment and the associated exclusionary rule is not to grant certain guilty defendants a windfall by letting them go free — though it sometimes does do that.
See Elkins v. United States,
With that in mind, we can better understand why anonymous tips trouble the courts and sometimes lead to the suppression of otherwisе reliable evidence. The first concern relates to the motives of the tipster. A tipster who refuses to identify himself may simply be making up the story, perhaps trying to use the police to harass another citizen. This is why the Supreme Court, in
White
and
J.L.,
has required that anonymous tips be accompanied by corroboration and “other indicia of
*1191
reliability.”
See J.L.
A second concern relates not to a tip’s anonymity but to its level of specificity. Overly generic tips, even if made in good faith, could give police excessive discretion to stop and search large numbers of citizens. This too was underlying the
J.L.
decision, where the Court emphasized the lack of detail in the tip, which only pointed to a young black man wearing a plaid shirt at a certain bus stop.
See
Though we are mindful of the concerns expressed in
J.L.,
they are mitigated by other facts here. First, although the dispatcher did not ask the caller’s name or address, he did give police his cell phone number.
See United States v. Jenkins,
Because the initial stop and conversation between Johnson and Officer Middleton was consensual, however, we need not decide whether the tip alone was sufficient under White and J.L. to provide reasonаble suspicion for a search. We simply hold that the tip and the accompanying information relayed to Officer Middleton, which included the dispatch’s priority level and a description of the people and situation, are sufficiently reliable to be analyzed as part of the totality of the circumstances.
2. The Initial Conversation
The district court, “assuming arguendo that the anonymous tip provided reasonable suspicion justifying the initial stop” ruled that any such reasonable suspicion “was dispelled after Officer Middleton’s initial contact” with them. Again, perhaps because the district court was incorrect in its determination оf when reasonable suspicion was necessary to justify Officer Middleton’s actions, its analysis of this issue fails to account for the totality of the circumstances standard.
It is true that Officer Middleton’s initial observation and conversation with the pair called into question much of the information in the tip. They both denied that Johnson had been forcing Samantha to do anything, and Samantha’s appearance did not belie their claims. Johnson’s gentle *1192 manly, if nervous, behavior likewise gave credence to their denials.
This does not mean, however, that Officer Middleton should have simply abandoned his investigation at this point, blithely sending the couple on their way in Albuquerque's most dangerous neighborhood. The Fourth Amendment does not require police to be so credulous. As Officer Middleton pointed out, in a kidnapping, domestic violence, or similar situation, Samantha would likely be intimidated when answering in front of Johnson, and both would have had an incentive to lie if they were involved in some other criminal activity such as prostitution or drug dealing. It is not an unreasonable inference that even before Officer Middleton pulled over in a marked police cruiser, the two knew an officer was wаtching them and behaved accordingly.
3. Johnson’s Nervousness
The district court next found that Johnson’s fidgeting and looking about was “entirely normal” and therefore not a pertinent factor in the reasonable suspicion analysis. The government disputes both the characterization of Johnson’s behavior and the decision not to consider it.
The first of these decisions by the district court — that Johnson’s behavior was not outside the range of normal reactions to police questioning — is a finding of fact, which we review only for clear error.
See Gandara-Salinas,
The district court’s decision that this means Johnson’s behavior was not part of the totality of the circumstances, however, is an incorrect application of the law. We have held that typical “nervousness alone cannot support' reasonable suspicion of criminal activity,” and “is of limited significance,” and that courts should “discount the detaining officer’s reliance on the detainee’s nervousness.”

(internal quotations and citations omitted). Conduct that may be wholly innocent may nonetheless support a finding of reasonable suspicion in certain circumstances.
United States v. Sokolow,
4. The Walkie-Talkie
After having rejected the tip and Johnson’s behavior, the district court went on to dismiss Johnson’s “handling of the walk-ie-talkie [as] a contributing factor to the reasonable suspicion determination.” Officer Middleton testified that Johnson’s handling of the walkie-talkie made him suspi *1193 cious because walkie-talkies are often used by people involved in drug dealing and other crime, and that by depressing the button Johnson could be signaling to someone that he was being confronted by police. The court refused.to consider this because Officer Middleton acknowledged that Johnson never spoke directly into the walkie-talkie and that he was not sure Johnson was actually calling someone.
The district court’s ruling on this point is directly contradicted by our holding in
Williams,
where we acknowledged that police have learned that such devices are often used by drug traffickers and that they suggest the close proximity of a co-conspirator.
See
5. The “War Zone”
The only factor the district court found relevant to the reasonable suspicion analysis was the dangerousness of the area in which the stop took place. Quoting
Illinois v. Wardlow,
6. The Totality of the Circumstances
In ignoring these reasons for Officer Middleton’s continuing suspicion, the district court “failed to accord deference to the [officer’s] ability to ‘draw on (his) own experience and specialized training to make inferences from and deductions about the cumulative information available to (him) that might well elude an untrained person.’”
Gandara-Salinas,
When we apply the proper legal analysis to the fact findings of the district court, then, the record shows that the following *1194 circumstances faced Officer Middleton at the time of the detention: (1) the police had received a call from a citizen who gave his phone number (but not his name) and described an adult male forcing a juvenile girl down the street; (2) the caller gave a detailed and accurate description of Johnson’s and Samantha’s appearance and where officers would find them; (3) the caller did not know if the man was armed; (4) the dispatcher requested that officers check on a suspicious person and attached the deрartment’s second-highest priority to it; (5) Officer Middleton’s brief observation did not suggest that Johnson was using force on Samantha; (6) Samantha and Johnson both denied the caller’s allegations when first questioned; (7) drug dealers, pimps, and kidnappers are often armed; (8) Johnson was nervous, if not abnormally so, but also cooperative and polite; (9) Johnson was depressing the transmission button on a walkie-talkie; (10) individuals involved in criminal activity often use walkie-talkies to communicate with each other; (11) the incident took place in Albuquerque’s highest-crime area.
Though we agree with Johnson that under thеse circumstances a reasonable person might have some doubts about the accuracy of the tipster and about Johnson’s actual involvement in criminal activity, we do not agree that such doubts made Officer Middleton’s actions unreasonable. “A determination that reasonable suspicion exists ... need not rule out the possibility of innocent conduct.”
Arvizu,
[rjeasonablе suspicion is a less demanding standard than probable cause not only in the sense that reasonable suspicion can be established with information that is different in quantity or content than that required to establish probable cause, but also in the sense that reasonable suspicion can arise from information that is less reliable than that required to show probable cause.
Tuter,
Under the speсific facts of this case, Officer Middleton had a reasonable suspicion that Johnson might be involved in one or more criminal activities, including drug dealing, kidnapping, or prostitution. His suspicions were particularized to Johnson, and were based on how his training and experience taught him to interpret a number of objectively reasonable details. This is more than the “inchoate and unparticu-larized suspicion or ‘hunch’ ” warned against in
Terry. See
B.
To satisfy
Terry’s
second prong Officer Middletоn’s actions must also have been “reasonably related in scope to the circumstances which justified the interference in the first place.”
An officer may take reasonable precautions to protect his safety during an investigative detention.
See Shareef,
Conclusion
The district court’s findings of fact are not clearly erroneous. Our de novo review of the legal conclusions to be drawn from those facts, however, shows that the district court erred in granting Johnson’s motion to suppress because Officer Middleton’s actions were objectively reasonable.
This is a close case. A reasonable officer in Officer Middleton’s shoes may have thought Johnson was in fact not involved in criminal activity. But every indication is that Officer Middleton acted just as society would want its law enforcement officers to act when investigating a suspicious situation. 5 He was aware of a number of facts that made him suspect that Johnson might be involved in potentially dangerous criminal activity. He did not threaten or intimidate Johnson, or do any more than was necessary to negate or, as it turned out, confirm his suspicions. He took modest steps to protect his and the public’s safety.
[W]here the officer’s conduct is objectively reasonable, “excluding the evidence will not further the ends of the exclusionary rule in any appreciable way; for it is painfully apparent that ... the officer is acting as a reasonable officer would and should act in similar circumstances. Excluding . the evidence can in no way affect his future conduct unless it is to make him less willing to do his duty.”
United States v. Leon,
The decision of the district court is therefore REVERSED and the case is REMANDED for further proceedings consistent with this opinion.
Notes
. Thоugh the girl later testified that she initially gave a false name because she had run away from foster care in Ohio, we will follow the district court’s lead and identify her herein as ''Samantha” for purposes of consistency. Neither Samantha nor Johnson immediately told Officer Middleton what their relationship was, but later testimony revealed that Johnson was a friend of Samantha's mother, with whom Samantha was staying in Albuquerque.
. Whether other remedies might better serve that purpose has provided the basis for much academic debate. See, e.g., Akhil Reed Amar, Against Exclusion (Except to Protect Truth or Prevent Privacy Violatiоns), 20 Harv. J.L. & Pub. Pol'y 457, 464 (1997) (''[T]he distribution of benefits under the exclusionary rule is 'upside down,' helping the guilty, not the innocent.”); William J. Stuntz, The Virtues and Vices of the Exclusionary Rule, 20 Harv. J.L. & Pub. Pol'y 443 (1997); Yale Kamisar, In Defense of the Search and Seizure Exclusionary Rule, 26 Harv. J.L. & Pub. Pol'y 119 (2003), and sources discussed therein at n. 1.
. Indeed, it seems unlikely that the tip would have given police a reason to stop any other couple in the state of New Mexico, let alone on a particular street in a high crime neighborhood in Albuquerque.
. Nor did it in
Wardlow
itself, where the Court upheld the detention of a suspect who had attempted to flee from police in a dangerous area.
. Mr. Johnson, by all accounts, also should be commended for his "gentlemanly,” honest, and civil behavior toward Officer Middleton. Unfortunately for all involved, before encountering Officer Middleton, he decided to break a federal law by carrying a weapon.
