Probable cause is used to justify which actions?

• A. Search or arrest
• B. Detain indefinitely
• C. Question suspects without cause
• D. None

Answer: (A)

Probable cause is the standard police use to justify taking certain actions, specifically searches and arrests. It means there’s a reasonable basis to believe a crime has been committed and that evidence or a suspect can be found where the action is to be taken. That’s why warrants for searches and arrests rely on this level of belief. It isn’t about detaining someone indefinitely or questioning a person without any justification; those situations involve different rules (detention without charge isn’t allowed, and stopping or questioning typically requires reasonable suspicion or other lawful basis). So, the action that best fits the role of probable cause is a search or an arrest.
