To articulate reasonable suspicion, an officer must state specific, observable facts and logical inferences that suggest a person is involved in criminal activity, going beyond a mere hunch but requiring less proof than probable cause for arrest, allowing for brief stops (Terry stops) or frisks for weapons if dangerous. Key elements include clear descriptions of behavior (e.g., swerving, hiding hands), location (high-crime area), and matching descriptions, all adding up under the "totality of the circumstances".

Reasonable suspicion is a legal standard in the U.S. allowing police to briefly detain and question someone, or perform a limited pat-down for weapons, if they have specific, articulable facts suggesting involvement in a crime, though it's a lower threshold than probable cause (needed for arrest/warrants). It requires more than a hunch but less than concrete evidence, relying on an officer's training and experience to draw logical inferences from objective observations that a crime has occurred, is occurring, or is about to occur.
