Which of the following is an exception to the warrant requirement?

• A. Reasonable suspicion
• B. Consent
• C. Stop and frisk
• D. Evidence beyond probable cause

Answer: (B)

Consent is an exception to the warrant requirement because it rests on the individual’s voluntary permission for a search or seizure. When someone with authority over the area or items freely agrees to let officers search, the police can proceed without a warrant or probable cause, as long as the consent is truly voluntary, not coerced, and the scope stays within what was granted. The consent can be withdrawn at any time, and questions about who has authority or whether the consent was truly voluntary matter for determining admissibility. Reasonable suspicion governs only brief detentions and stops, not broad warrantless searches, so it doesn’t by itself justify a general search without a warrant. Stop and frisk is a narrow exception that allows a limited pat-down when there is reasonable suspicion of danger, not a general warrantless search of a larger area. There isn’t a valid exception called “evidence beyond probable cause”—without a recognized exception or probable cause, evidence obtained would be inadmissible.
