PAMELA HARRIS, Circuit Judge:
On an afternoon in 2014, the Ranson, West Virginia police
department received an anonymous tip that a black man had loaded
a gun in a 7-Eleven parking lot and then concealed it in his
pocket before leaving in a car. A few minutes later, the police
stopped a car matching the description they had been given,
citing a traffic violation. Shaquille Montel Robinson, a black
man, was a passenger in the car. After Robinson exited the
vehicle at police request, an officer frisked Robinson and
discovered a firearm in the pocket of Robinson’s pants.
Under Terry v. Ohio, 392 U.S. 1 (1968), the police may
conduct a limited pat-down for weapons when there is reasonable
suspicion that a suspect is both armed and dangerous. “Armed”
is not a problem in this case: Assuming the credibility of the
anonymous tip, which we may for purposes of this appeal, the
police had reason to believe that Robinson was armed when they
stopped him. But “dangerous” is more difficult, and what makes
it difficult is that West Virginia law authorizes citizens to
arm themselves with concealed guns. Because the carrying of a
concealed firearm is not itself illegal in West Virginia, and
because the circumstances did not otherwise provide an objective
basis for inferring danger, we must conclude that the officer
who frisked Robinson lacked reasonable suspicion that Robinson
was not only armed but also dangerous. Accordingly, we reverse
the district court decision denying Robinson’s motion to
suppress the evidence uncovered by this unlawful search.
