Which standard allows a brief detention and questioning short of arrest?

• A. Reasonable suspicion
• B. Probable cause
• C. Beyond a reasonable doubt
• D. Consent

Answer: (A)

Reasonable suspicion allows a police officer to briefly detain someone and ask questions to investigate possible criminal activity. It must rest on specific, articulable facts and rational inferences from those facts, considered together with the total circumstances. This is the level of justification established in Terry v. Ohio for short stops or detentions that are limited in duration and scope—the goal is to confirm or dispel the suspicion, not to arrest.

If the situation develops into probable cause—a stronger standard indicating a reasonable belief the person has committed a crime—the officer can arrest. If the person’s innocence becomes clear or the suspicions are dispelled, the detention ends and the individual should be released. The other options don’t fit because: probable cause is needed for arrest, not just a brief stop; beyond a reasonable doubt is the standard of proof required for conviction, not for detaining someone; consent means the person agrees to the stop or search, which is voluntary and not the standard that justifies a detention on suspicion.
