Reasonable suspicion
Reasonable suspicion or reasonable articulable suspicion is a legal standard of proof that may be required in many jurisdictions, particularly in common law countries. In the United States law it is considered is less than probable cause, the legal standard for arrests and warrants, but more than an "inchoate and unparticularized suspicion or 'hunch'"; it must be based on "specific and articulable facts", "taken together with rational inferences from those facts", and the suspicion must be associated with the specific individual.
