Opinion of the court

The court held that this "reasonable suspicion" standard must apply to both the initial stop and the frisk. It said that a police officer must have reasonable suspicion to stop a suspect in the first place and that an officer could then frisk a stopped suspect if he or she had reasonable suspicion that the suspect was armed and dangerous, or if, in the officer's experience, the suspected criminal activity was of a type that was "likely" to involve weapons. The sole purpose of the officer's frisk could only be to ensure the suspect was not armed, and so had to be limited to a pat-down of the suspect's outer clothing.
