The reasonable suspicion standard is a legal basis allowing police to briefly detain and question someone if they have specific, articulable facts, combined with training and experience, suggesting criminal activity is afoot, short of probable cause but more than a mere hunch. This allows for limited investigative stops (like Terry stops) and frisks for weapons, balancing public safety with civil liberties, requiring officers to justify their actions with objective observations rather than just intuition.
