Which standard of proof requires articulable facts and reasonable inferences to lead to belief that a crime has been or is about to be committed?

• A. Probable cause
• B. Beyond a reasonable doubt
• C. Preponderance of the evidence
• D. Reasonable suspicion

Answer: (A)

Probable cause is the standard that requires articulable facts and reasonable inferences to lead to belief that a crime has been or is about to be committed. It’s the threshold used to justify arrests and to issue warrants. The idea isn’t certainty, but something stronger than a mere hunch: the facts and circumstances known to the officer, evaluated as a reasonable person would, must make it plausible that criminal activity is happening or about to occur. This assessment uses the totality of the circumstances at the time.

This standard sits above reasonable suspicion, which is enough for a brief investigative stop or lighter restraint, but below the higher bar of proof needed to convict a person in court, which is beyond a reasonable doubt. It also differs from the civil standard of preponderance of the evidence, which asks whether something is more likely than not to be true in civil cases.
