Which factor can constitute reasonable suspicion during a pat down?

The presence of companions of a suspect revealing weapons can constitute reasonable suspicion during a pat-down, as it relates directly to the potential threat posed to the officer and the public. When officers observe individuals in the immediate vicinity of a suspect openly displaying weapons, it raises a concern about the suspect's intentions and the potential for violence or a confrontation. This information can help an officer develop reasonable suspicion that the suspect may also be armed or engaged in criminal activity, justifying the need for a protective pat-down to ensure safety.

Calm behavior by the suspect, being in a non-violent neighborhood, and the time of day being early morning do not inherently signify a risk or threat, and thus would not typically contribute to reasonable suspicion. The focus on companions displaying weapons highlights a clear and immediate concern for safety, which is a key factor in determining the necessity and legality of a pat-down procedure.
