Reasonable suspicion

SIGNIFICANCE: Reasonable suspicion is an important legal concept that sets a standard that permits criminal justice professionals, such as police and correctional officials, to stop and detain suspects for further investigation.

When law-enforcement officers stop and detain suspects, they must have tangible reasons for suspecting that the suspects they stop are involved in criminal activities. What constitutes reasonable suspicion is based on such factors such as the suspects’ appearances and behavior; information about the suspects gathered from previous encounters or provided by reliable sources, such as police files and databases; the locations and circumstances of the encounters with the suspects; and the officers’ own training, experience, and relevant general knowledge. After stopping suspects on reasonable suspicion, the officers may detain them until their suspicions are either confirmed or proven to be unfounded.

A typical example might be a police officer who has reasonable suspicion that a suspect is carrying a concealed handgun because there is an obvious bulge around the suspect’s waistband, where handguns are often hidden. The investigating officer may also know from previous encounters with the same suspect that the latter has a past arrest and conviction for weapons violations. An example of an unreasonable suspicion would be suspecting that a person seen for the first time is carrying illegal drugs because that person looks like a hippie.
