The police must have a reasonable suspicion that a crime has been, is being, or is about to be committed by the suspect.
Explanation:
If the police reasonably suspect that the suspect is armed and dangerous, the police may frisk the suspect, meaning that the police will give a quick pat-down of the suspect's outer clothing.
