Which statement defines probable cause?

• A. Reasonable suspicion describes belief a crime is in progress.
• B. Probable cause is an officer's objective belief a crime is in progress or has been committed.
• C. Probable cause is the same as reasonable doubt.
• D. Probable cause is based solely on rumors.

Answer: (B)

Probable cause is the officer's objective belief, based on facts and circumstances known at the time, that a crime has been committed or is in progress. This belief must be reasonable and grounded in reliable information, not a mere hunch or rumor. It lies between a mere suspicion and absolute certainty, and it is the standard used to justify arrests and to obtain warrants. Reasonable suspicion describes a lower threshold used for stops or detentions, not for arrests or searches, so it isn’t the correct definition. A belief based solely on rumors fails to meet the factual, evidence-based requirement. And probable cause is not the same as reasonable doubt—doubts about guilt aren’t the standard used to justify law enforcement actions.
