Reasonable Suspicion

A belief based on specific observable facts and circumstances, not a mere hunch, that a person has been, is, or is about to be involved in wrongdoing, justifying a cautious inquiry or observation.

Related: Probable Cause, Citizen's Arrest, Use of Force Continuum

Related: Reasonable Suspicion, Citizen's Arrest
Citizen's Arrest

Related: Detention, Reasonable Suspicion, Use of Force Continuum

Related: Citizen's Arrest, Excessive Force
Use of Force Continuum

Related: Excessive Force, Restraint, De-escalation
