How is probable cause defined?

• A. A fair probability that a crime has been committed or evidence exists; justifies arrests and searches.
• B. A mere hunch by an officer.
• C. A standard that applies only to searches, not arrests.
• D. A preponderance standard used in civil cases.

Answer: (C)

Probable cause means a fair probability that a crime has been committed or that evidence of a crime is present, based on facts and circumstances known to the officer at the time. It isn’t a certainty, but it’s more than a guess; it’s enough to lead a reasonable person to believe that criminal activity is likely or that evidence is where it’s claimed to be. This standard justifies both making an arrest and conducting a search (often with a warrant). It requires more than a mere hunch, which is insufficient. It also applies to arrests and searches, not just searches. The preponderance standard described in civil cases is weaker and would not meet the criminal-law threshold for arrest or search authority.
