What is "reasonable suspicion"?

• A. A requirement that allows law enforcement to pursue a suspect for a lengthy investigation
• B. A standard used in criminal procedure that allows law enforcement to briefly detain a person for questioning
• C. A belief that a crime is likely to occur based solely on intuition
• D. A well-founded certainty that a suspect is guilty of a crime

Answer: (B)

Reasonable suspicion is a legal standard that permits law enforcement officers to make brief stops and detain individuals for questioning if they have specific and articulable facts that suggest criminal activity is afoot. This standard is lower than probable cause, which is required for arrest or obtaining search warrants.

In practice, reasonable suspicion allows officers to stop a person based on their observations or information known to them at the time. It emphasizes the need for some factual basis—beyond mere hunches or intuition—supporting their belief that the individual is involved in criminal activity. This can include factors such as unusual behavior, proximity to a crime scene, or a suspect fitting the description of someone involved in a crime.

The other options do not accurately describe reasonable suspicion. For instance, pursuing a lengthy investigation implies a higher threshold of evidence and justification (probable cause), while intuition alone lacks the necessary factual basis to justify detention. Furthermore, having a "well-founded certainty" regarding guilt would mean probable cause is present, which is a different legal standard from reasonable suspicion. Thus, the correct understanding of reasonable suspicion directly correlates to its use by law enforcement for brief detentions rather than longer investigations or arrests.
