Which statement correctly distinguishes reasonable suspicion from probable cause?

• A. Reasonable suspicion requires probable cause to be formal.
• B. Probable cause is a plausible belief that criminal activity may be afoot.
• C. Reasonable suspicion is a plausible belief that criminal activity may be afoot; probable cause is a higher standard requiring a fair probability that a crime has been or is being committed and that evidence exists.
• D. Reasonable suspicion and probable cause are identical standards.

Answer: (C)

The key idea here is the difference in justification levels for police action: reasonable suspicion versus probable cause. Reasonable suspicion is a plausible belief that criminal activity may be afoot, based on specific, articulable facts and reasonable inferences. It’s enough to briefly detain and investigate under Terry v. Ohio, but not enough for arrest or a search. Probable cause is a higher standard, requiring a fair probability that a crime has been or is being committed and that evidence exists to prove it; this level supports arrest or obtaining a search warrant. This option is the best because it correctly pairs reasonable suspicion with a plausible, lower level of belief and ties probable cause to a higher, evidence-based standard. The other statements misstate the relationship: one implies reasonable suspicion needs probable cause to be valid, another reduces probable cause to a mere belief about criminal activity, and another falsely says the two standards are identical.
