Which standard allows police to briefly detain a person when their behavior is suspicious but not enough to arrest?

• A. Reasonable Suspicion
• B. Probable Cause
• C. Beyond a Reasonable Doubt
• D. Preponderance of the Evidence

Answer: (A)

Reasonable suspicion is the standard that allows police to briefly detain someone for investigation when their behavior is suspicious but not enough to arrest. This concept comes from Terry v. Ohio, which authorizes a stop-and-frisk when an officer has specific, articulable facts that criminal activity may be afoot and that stopping the person is necessary to confirm or dispel the suspicion. The detention must be brief and focused, lasting only as long as needed to investigate the suspicious behavior. The officer may perform a protective frisk for weapons if there’s a reasonable belief the person is armed and dangerous, but any search beyond a pat-down requires stronger justification. If during the stop new facts establish probable cause for an arrest, the situation can shift accordingly; if such facts never emerge, the stop ends and the person must be released. In contrast, all the other standards involve a higher burden: probable cause is needed to arrest or search with a warrant, beyond a reasonable doubt is the standard for conviction in court, and preponderance of the evidence is used in civil cases.
