Reasonable suspicion is determined by law enforcement officers (and sometimes supervisors in specific contexts like drug testing) who use "specific, articulable facts" and "common-sense judgments" about a person's behavior, appearance, or circumstances to conclude that criminal activity might be occurring, more than a hunch but less than probable cause, a standard established by cases like Terry v. Ohio. This "totality of the circumstances" allows officers to briefly detain or investigate individuals, with courts later reviewing if the officer's observations justified the stop.
