Probable cause definition: Which statement best captures it?

• A. Based on a single officer's belief without corroboration
• B. Based on the totality of the circumstances; may require corroboration
• C. The standard is lower than probable cause
• D. The standard is based on rumor

Answer: (B)

Probable cause means having a reasonable basis to believe that a crime is being committed, has been committed, or that evidence of a crime will be found in a particular place. The strength of that belief comes from looking at the totality of the circumstances—the complete set of facts the officer knows at the moment, not just a single clue. This approach allows different pieces of information to combine, so observations, training, and information from reliable sources can together justify action. Corroboration often plays a role, strengthening a belief when tips or rumors are supported by additional evidence or observations. It’s a threshold higher than mere suspicion but not as high as proof beyond a reasonable doubt, and it determines when a stop, arrest, or search is legally defensible under the Fourth Amendment.
