How is "totality of circumstances" used in evaluating reasonable suspicion?

• A. A single decisive factor is enough.
• B. All factors together, not any single factor alone.
• C. Only the officer's intuition matters.
• D. Demeanor alone determines suspicion.

Answer: (B)

Totality of the circumstances means the stop is justified only after weighing all available factors together, not based on any single piece of information. In evaluating reasonable suspicion, officers look at how the scene fits the whole context: location and time, the person’s behavior (like furtive movements or avoidance of contact), observable actions (trying to conceal something, running, or checking surroundings), and any relevant corroborating details (prior knowledge, reports, or matching a suspect description). None of these factors alone proves crime is afoot, but when combined they can create a specific, articulable reason to suspect involvement in criminal activity. The standard is objective—what a reasonable officer would deduce from the entire situation, rather than relying on intuition or a lone sign. For example, nervous pacing in a high-crime area at night might be suspicious only if accompanied by other cues, such as attempting to hide possession or evading questioning. Conversely, a similar demeanor or action in a safe, ordinary context might be innocent.
