                             OPINION

NIEMEYER, Circuit Judge:

   City of Richmond police officers stopped and frisked Irvin Mayo
while he was walking in a high-crime area of Richmond, Virginia.
The officers had observed Mayo react to their presence by placing his
hand in his left pocket and thereafter conduct himself in an evasive
and suspicious manner, manifesting culpability to the officers. On
stopping and frisking Mayo — under the authority of Terry v. Ohio,
392 U.S. 1 (1968) — the officers recovered a handgun, leading to
Mayo’s indictment for possession of a firearm in furtherance of drug
trafficking and other related charges. The district court, concluding
that the circumstances were covered by our decision in United States
v. Burton, 228 F.3d 524 (4th Cir. 2000), felt compelled to grant
Mayo’s motion to suppress the evidence seized following the officer’s
stop and frisk.

   Because Burton presented distinguishing facts — the officers in
Burton conceded that they had "no indication that [the defendant] was
at the time engaging in any illegal activity," whereas the officers in
this case asserted that they had a reasonable suspicion supported by
articulable facts that Mayo was possessing a concealed weapon — we
conclude that this case is not controlled by Burton. On review of the
facts found in this case, we conclude that the officers had authority
to stop and frisk Mayo, and, therefore, we reverse and remand this
case for further proceedings.

                                  I

   During the afternoon of February 14, 2003, City of Richmond
Police Officers Kenneth Cornett and C.G. Johnson were driving in a
marked patrol car through a "high-crime" neighborhood on the south
side of Richmond. This neighborhood had recently been designated
as a target area for the police department’s "Wave Initiative," which
was designed to respond to community problems and citizen com-
plaints stemming from drug dealing. In addition, Officer Cornett
knew the area to be a high-crime area. In the weeks preceding Febru-
ary 14, two shootings had occurred in the neighborhood, and Cornett
                       UNITED STATES v. MAYO                         3
himself had recovered firearms and drugs in connection with three
separate incidents.

   While traveling through the neighborhood on February 14, Officers
Cornett and Johnson observed Mayo standing in the middle of the
street, talking to another person who was on the side of the street.
When Mayo observed the approaching police car, he reactively "put
his left hand into his left hand jacket pocket, turned 180 degrees,
walked out of the street and onto the [apartment] complex property
that is posted no trespassing and through that property between two
buildings." Officer Cornett observed that Mayo "either . . . had some-
thing heavy in [his] pocket or he was pushing his hand down" into the
pocket, a movement that Officer Cornett believed was consistent with
an individual’s effort to maintain control of a weapon while moving.
The officers drove around the corner and waited to see if Mayo would
emerge from the other side of the apartment complex. When Mayo
did emerge and observe the officers again, he "immediately stopped,
just froze in his tracks for a split second, then started walking along
the side of the building."

   At this point, Officer Cornett exited the patrol car and approached
Mayo with his badge displayed. As Officer Cornett asked Mayo if he
could speak with him, Officer Johnson requested that Mayo remove
his left hand from his pocket, which Mayo did. When Officer Cornett
asked Mayo whether he lived in the apartment complex, Mayo gave
no answer but reacted in a peculiar manner. Officer Cornett observed
that Mayo’s "eyes were extremely wide, his mouth was slightly
agape, and it was almost like nothing registered with him. It was
almost as if he was in shock." The officer also observed that Mayo’s
shirt was "fluttering . . . as though he was shaking." Officer Cornett
asked Mayo if he had a weapon, at which point Mayo averted his
eyes, looking downward, and said nothing. This reaction made Offi-
cer Cornett "nervous," prompting him to inform Mayo that he was
going to pat Mayo down "for my safety." Mayo responded to this
statement by raising his hands halfway up. When Officer Cornett
frisked Mayo, he found a semiautomatic pistol in his left jacket
pocket, the pocket into which Mayo had earlier inserted his hand
when the officers first approached him in the patrol car.

  The officers seized the pistol, arrested Mayo for carrying a con-
cealed weapon without a permit, handcuffed him, and read him his
4                      UNITED STATES v. MAYO
Miranda rights, to which Mayo responded with a nod of acknowledg-
ment. In response to Officer Cornett’s questions whether Mayo had
any drugs on him, Mayo again averted his eyes and said nothing. The
officers then conducted a search incident to arrest, during which they
recovered several rocks of crack cocaine and marijuana.

   Mayo was indicted on three counts for drug violations and one
count for possession of a firearm in furtherance of drug trafficking.
Before trial, Mayo moved to suppress the evidence seized by Officer
Cornett, contending that the stop by the officers violated his Fourth
Amendment rights and was not justified by "a reasonable suspicion
supported by articulable facts" as required by Terry v. Ohio, 392 U.S.
1 (1968). The district court considered Officer Cornett’s stop-and-
frisk in light of our ruling in United States v. Burton, 228 F.3d 524
(4th Cir. 2000) (concluding that police officers in circumstances pre-
sented there did not have a reasonable suspicion to frisk the defen-
dant), and determined that Officer Cornett’s search of Mayo fell
"squarely within the holding of Burton." The court reached this con-
clusion notwithstanding its observation that "there is evidence that the
defendant was carrying — that in the view of the officer, the defen-
dant was acting in such a way as to — that was consistent with some-
body who was carrying a weapon."

   From the district court’s order suppressing the evidence as the fruit
of an improper stop under Terry v. Ohio, 392 U.S. 1 (1968), the gov-
ernment prosecuted this appeal.

                                   II

   The government contends that Officer Cornett had a reasonable
suspicion supported by articulable facts to believe that criminal activ-
ity may have been afoot; Mayo may have been carrying a concealed
weapon without a permit, in violation of Virginia Code § 18.2-308.
It argues that Officer Cornett’s suspicion was "based on the defen-
dant’s furtive and evasive conduct in a high-crime area, the way he
was holding his left hand in his jacket pocket, his physical response
to the confrontation with police officers, and his response to questions
regarding where he lived and whether he was carrying any weapons."
The government argues that the district court erred in concluding that
                        UNITED STATES v. MAYO                           5
the circumstances here are controlled by United States v. Burton, 228
F.3d 524 (4th Cir. 2000), because that case is distinguishable.

   Mayo contends that not only are the circumstances here covered by
Burton, the circumstances here are "more favorable" to Mayo in that
"Mayo complied with the officer’s request that he remove his hand
from his jacket" — a fact that Mayo argues gives an indication that
the officer no longer "had any further reason to believe that [Mayo]
had a weapon."

  In granting Mayo’s motion to suppress, the district court credited
Officer Cornett’s version of the facts but concluded that they fell
under the holding of Burton:

     I find that the totality of the circumstances here puts this
     case squarely within the holding of Burton, notwithstanding
     that there is evidence that the defendant was carrying — that
     in the view of the officer, the defendant was acting in such
     a way as to — that was consistent with somebody who was
     carrying a weapon.

Although ultimately concluding that the officers did not have a rea-
sonable articulable suspicion that Mayo "was engaged in criminal
activity," in reaching this conclusion, the court appears to have
focused on whether the Richmond police officers had a legitimate
safety concern. Viewing Burton as a ruling focusing on the safety
concern, the district court noted that in Burton the defendant refused
to remove his hand when asked to. The court paraphrased the dissent-
ing opinion in Burton, stating, "And Burton’s nonresponse to the
request that he remove his hand from the coat constituted, crediting
the practical experience of the officers, an entirely reasonable safety
concern." See Burton, 228 F.3d at 530 (King, J., dissenting). The dis-
trict court apparently reasoned, because we held in Burton that the
officers were not justified in frisking the defendant, a priori, this case
fell well within Burton because Mayo indeed did remove his hand,
presenting less of a risk to the officers. Therefore, the circumstances
in this case fell within the district court’s understanding of the holding
of Burton, and it accordingly granted Mayo’s motion to suppress.

  The principles to be applied to this case are now well fixed.
Although the Fourth Amendment prohibits unreasonable seizures of
6                       UNITED STATES v. MAYO
persons, a police officer may temporarily stop a citizen "where [the]
police officer observes unusual conduct which leads him reasonably
to conclude in light of his experience that criminal activity may be
afoot." Terry, 392 U.S. at 30. Moreover, in connection with such a
stop, if the officer believes that the person being stopped "may be
armed and presently dangerous," the officer may frisk the person by
patting his outer clothing "in an attempt to discover weapons which
might be used to assault [the officer]." Id.; see also Adams v. Wil-
liams, 407 U.S. 143, 146 (1972).

   In reviewing the legality of Terry stops, we consider the "‘totality
of the circumstances’ of each case to see whether the detaining officer
has a ‘particularized and objective basis’ for suspecting legal wrong-
doing." United States v. Arvizu, 534 U.S. 266, 273 (2002) (citing
United States v. Cortez, 449 U.S. 411, 417-18 (1981)). And relevant
to the totality of circumstances are various individual factors tradi-
tionally relied upon by police officers, such as whether the stop
occurred in a high-crime area, see Illinois v. Wardlow, 528 U.S. 119,
124 (2000) (citing Adams, 407 U.S. at 144, 147-48), or whether the
suspect engaged in evasive behavior or acted nervously, see id. (citing
United States v. Brignoni-Ponce, 422 U.S. 873, 885 (1975); Florida
v. Rodriguez, 469 U.S. 1, 6 (1984) (per curiam); United States v.
Sokolow, 490 U.S. 1, 8-9 (1989); see also United States v. McFarley,
991 F.2d 1188, 1192 (4th Cir. 1993) (identifying as "unusually ner-
vous" such behavior as shaking hands, heavy breathing, and providing
inconsistent answers). A suspect’s refusal to cooperate with police,
without more, does not satisfy Terry stop requirements. See Wardlow,
528 U.S. at 125 (citing Florida v. Bostick, 501 U.S. 429, 437 (1999)).
At bottom, the basis for a Terry stop is that the officer have a "reason-
able suspicion supported by articulable facts that criminal activity
‘may be afoot,’ even if the officer lacks probable cause." Sokolow,
490 U.S. at 7.

   We applied this jurisprudence in Burton to conclude that police
officers there did not have a reasonable suspicion supported by
articulable facts that criminal activity was afoot. Accordingly, we
concluded that a frisk of the suspect, conducted to allay the officers’
safety fears, was not justified. The essence of our holding in Burton
was that "an officer may not conduct this protective search for pur-
                        UNITED STATES v. MAYO                          7
poses of safety until he has a reasonable suspicion that supports the
investigatory stop." 228 F.3d at 528 (emphasis added).

   In Burton, a group of police officers were walking through a neigh-
borhood to serve outstanding warrants. When they approached Bur-
ton, who was standing at a pay phone with his right hand in his coat
pocket, they identified themselves as police officers and requested
identification from him. Burton did not respond to questions, nor did
he move. He remained standing just as the officers found him. When
one officer asked Burton to remove his hand from his coat pocket,
Burton again remained unresponsive and did not move. One of the
officers then reached into Burton’s pocket and discovered a firearm.
To justify this action, the officers explained that Burton’s refusal to
remove his hand from his coat made the officers feel "uneasy about
our safety being there with him with his hand and no response, you
know, towards us." 228 F.3d at 526. While the officers might have
appropriately been concerned for their safety, seeing a citizen stand
strangely mute without responding to their questions and having his
hand in his coat pocket, the officers readily conceded that they were
unaware of any outstanding warrants against Burton and that Burton
"exhibited no evasive or suspicious behavior and [that] there was no
indication that he was at the time engaging in any illegal activity." Id.
at 527. Thus in Burton, the officers conceded that they did not have
any suspicion that criminal activity was afoot, even though they did
fear for their safety while talking to Burton. We held that an officer
may not conduct a protective search to allay a reasonable fear that a
suspect is armed without first having a reasonable suspicion that sup-
ports an investigatory stop. Quoting from Terry we said:

    [P]olicemen have no more right to "pat down" the outer
    clothing of passers-by or persons to whom they address
    casual questions, than does any other citizen. . . . [I]f the
    frisk is justified in order to protect the officer during an
    encounter with a citizen, the officer must first have constitu-
    tional grounds to insist on an encounter, to make a forcible
    stop. . . . [T]he person addressed . . . certainly need not sub-
    mit to a frisk for the questioner’s protection.

Id., at 528 (emphasis in the original) (quoting Terry, 392 U.S. at 32-
33 (Harlan, J., concurring)); see also Adams, 407 U.S. at 146 ("So
8                       UNITED STATES v. MAYO
long as the officer is entitled to make a forcible stop, and has reason
to believe that the suspect is armed and dangerous, he may conduct
a weapons search limited in scope to this protective purpose" (empha-
sis added)).

   Thus, Burton must be understood to authorize a protective frisk
only when a Terry stop is authorized by a reasonable suspicion that
criminal activity is afoot. To conduct the protective frisk there must
also be reasonable grounds to believe that the suspect is armed and
dangerous. Absent a reasonable suspicion of criminal activity, a
police officer may not simply approach a citizen, as part of a police-
citizen encounter, and frisk the citizen because the officer believes
that his safety is at risk.

   In this case, when the district court focused on the officer’s safety,
and not on whether the officers had a reasonable suspicion to believe
that criminal activity was afoot, the court misunderstood the holding
of Burton. Surely if officers’ safety were an appropriate justification
for Mayo’s stop, then the district court might have been correct in
observing that the officers here had less concern for safety than did
the officers in Burton because in this case Mayo removed his hand
from his pocket. But the fact that Mayo removed his hand from his
pocket did not reduce the level of suspicion that the officers had that
Mayo was violating the law by carrying a concealed weapon without
a permit. Had the court considered whether criminal activity was
properly suspected, its own conclusion would have resulted in a dif-
ferent ruling. As the district court observed, in this case "there is evi-
dence that the defendant was carrying — that in the view of the
officer, the defendant was acting in such a way as to — that was con-
sistent with somebody who was carrying a weapon." In Burton there
concededly was no such evidence. See Burton, 228 F.3d at 527.
Accordingly, we conclude that the district court erred in applying
Burton to grant the motion to suppress in this case.

   When we evaluate the circumstances found in this case to deter-
mine whether the Richmond police officers had a reasonable suspi-
cion to stop Mayo under the principles of Terry v. Ohio, we conclude
that they did.

   First, we note that Officer Cornett’s encounter with Mayo occurred
in a high-crime area that had been targeted for special enforcement by
                       UNITED STATES v. MAYO                          9
the City of Richmond. Although standing alone this factor may not
be the basis for reasonable suspicion to stop anyone in the area, see
Brown v. Texas, 443 U.S. 47, 52 (1979), it is a factor that may be con-
sidered along with others to determine whether police have a reason-
able suspicion based on the totality of the circumstances, see
Wardlow, 528 U.S. at 124.

   Second, Mayo’s activity upon viewing the marked patrol car sug-
gested that he might be carrying a gun. The way Mayo put his hand
in his pocket and the appearance of something heavy in his pocket
suggested to the officers that Mayo had put his left hand onto a gun
to protect it while he was moving.

   Third, upon seeing the police, Mayo sought to evade their scrutiny.
When he saw the approaching police car, Mayo "turned 180 degrees"
and walked from the street into an adjacent apartment complex. And
when he came out the other side, only to view the police again, he
reacted in a shocked manner, thereafter proceeding to walk away.

   Fourth and finally, when the officers confronted Mayo, he evinced
an unusually nervous behavior. He averted his eyes to avoid those of
the officers, and his nervousness was palpable.

   Confronted with the totality of these circumstances, the officers
told Mayo that for their own safety they wished to pat him down, and
Mayo raised his hands halfway while the frisk was conducted. The
frisk itself amounted to a patting of Mayo’s outside clothing, which
revealed the gun. At that point, the officers had probable cause to
arrest Mayo and to search him incident to an arrest, leading to the dis-
covery of drugs.

   In summary, the undisputed evidence, considered in its totality,
indicates that Mayo reacted to the presence of police in a manner that
indicated to trained police officers that he might be carrying a gun in
his left pocket, in violation of Virginia Code § 18.2-308 (making it
unlawful to carry a concealed weapon without a permit). Because the
officers’ suspicion was reasonable and was supported by articulable
facts, the officers had a right to stop Mayo and, because they reason-
ably believed Mayo was armed, to pat him down in the interest of
10                     UNITED STATES v. MAYO
their personal safety. See Adams, 407 U.S. at 146. As we made clear
in Burton:

     Once an officer has a basis to make a lawful investigatory
     stop, he may protect himself during that stop by conducting
     a search for weapons if he "has reason to believe that the
     suspect is armed and dangerous."

228 F.3d at 528 (quoting Adams, 407 U.S. at 146). The legal pat down
by Officer Cornett yielded a weapon, leading to Mayo’s arrest and a
legal search incident to that arrest.

  Accordingly, we reverse the district court’s order granting the
motion to suppress and remand this case for further proceedings.
