Which factors help determine reasonable suspicion during a stop?

• A. Only a hunch.
• B. Personal gossip about the suspect.
• C. The suspect's appearance alone.
• D. Specific, articulable facts, observed pattern behavior, and the totality of the circumstances leading to a reasonable belief of involvement in criminal activity.

Answer: (D)

Reasonable suspicion exists when there are specific, articulable facts that, when weighed with the totality of the circumstances, would lead a reasonable officer to believe that criminal activity is afoot. It’s not about a gut feeling or a single cue; it’s about describing observable details—actions you can articulate—that fit a pattern of behavior you’re trained to recognize, combined with the context of where and when the event occurs and any related information you’ve gathered. The totality of the circumstances matters, so multiple factors together create the reasonable belief, rather than one vague hint. Appearance alone or unverified gossip cannot justify a stop, because they aren’t based on observable facts. When the combination of concrete observations and context points toward possible criminal activity, a stop is considered legally reasonable and permissible to pursue further investigation.
