Which statement best describes probable cause?

Which statement best describes probable cause?

• A. A belief that a person is likely involved in criminal conduct, requiring no evidence.
• B. A mere hunch that a person is involved in criminal activity.
• C. Evidence beyond a reasonable doubt is required to justify detentions.
• D. Probable cause is a reasonable belief that a crime has been or is being committed, justifying warrants.

Answer: (D)

Probable cause means a reasonable belief, based on facts and circumstances known to the officer, that a crime has been or is being committed, which justifies issuing a warrant or making an arrest. This standard sits between a mere guess and proof beyond a reasonable doubt, requiring more than speculation but not the certainty of conviction. The statement that describes probable cause this way is the best because it correctly ties together the basis for the belief (facts and circumstances) with the consequence (permission to obtain a warrant or detain). The other descriptions misstate the idea: a belief with no evidence is not enough; a mere hunch is insufficient; and requiring proof beyond a reasonable doubt is the standard for conviction, not for establishing probable cause for warrants or detentions.
