Which of the following could constitute reasonable suspicion?

• A. A furtive gesture (concealing)
• B. A dog barking at a distance
• C. A traffic violation explained by the driver
• D. An unrelated rumor

Answer: (A)

Reasonable suspicion arises when officers observe specific, articulable facts that would lead a reasonable person to believe criminal activity is afoot, evaluated under the totality of circumstances. A furtive gesture—such as concealing something or trying to hide actions—fits as a meaningful indicator because it suggests an attempt to withhold or hide contraband or weapons. When an officer sees this kind of behavior, especially in a context that heightens concern (time of day, location, prior known activity, oddness of the conduct), it can provide a plausible basis for a brief stop to investigate further. It’s one of those factors that can push the assessment toward reasonable suspicion, even though no single act on its own may prove it.

The other scenarios don’t fit as well because they lack a direct link to potential criminal activity. A dog barking at a distance doesn’t show the person’s actions or intent. A traffic violation explained by the driver provides a legitimate justification, reducing suspicion. An unrelated rumor is hearsay and not an observable fact that can support reasonable suspicion.
