Which statement best defines probable cause?

• A. A fair probability that a crime has been or is being committed.
• B. A minimal level of suspicion required to justify a brief stop.
• C. Proof beyond a reasonable doubt.
• D. A preponderance of the evidence.

Answer: (A)

Probable cause means a fair probability that a crime has been or is being committed, based on the facts and circumstances available to the officer. It’s a threshold that sits between a mere hunch and absolute certainty: enough to make an arrest or obtain a warrant, but not requiring proof beyond a reasonable doubt. This standard is higher than the level needed for a routine stop, which is reasonable suspicion, and it’s lower than the proof required to convict someone in court, which is beyond a reasonable doubt. It’s also different from a civil standard like a preponderance of the evidence, which asks whether something is more likely true than not. So the described criterion—a fair probability that a crime has been or is being committed—best captures what probable cause means.
