• A. Reasonable doubt
• B. Probable cause
• C. Beyond a shadow of a doubt
• D. Hunch

Answer: (B)

Probable cause is the standard that allows an arrest or a search when there is a reasonable basis to believe a crime occurred or evidence is present. It sits between mere suspicion and proof beyond a reasonable doubt: officers must have facts and circumstances that would lead a reasonable person to conclude that a crime has been committed and that the person or place involved is connected to it. This level of belief justifies actions like arrest without a warrant or obtaining a search warrant, and it’s based on the information available at the time, not on absolute certainty. It’s stronger than a hunch or guess and distinct from the guilt standard used at trial. Reasonable doubt relates to jurors deciding guilt in court, not to initial police action. A hunch is insufficient because it isn’t grounded in observed facts or circumstances.
