What is defined as a brief, temporary involuntary detention of a person suspected of criminal activity?

A brief, temporary involuntary detention of a person suspected of criminal activity is defined as a Terry stop. This term originates from the landmark U.S. Supreme Court case Terry v. Ohio, which established that law enforcement officers have the right to stop and briefly detain a person based on reasonable suspicion that the individual is involved in criminal activity.

During a Terry stop, officers can ask questions, check for identification, and perform a limited pat-down for weapons if they have reasonable concerns for their safety. It's important to note that this type of stop does not require the same level of evidence as an arrest, which requires probable cause.

Understanding the framework of a Terry stop is crucial for law enforcement officers as it balances the need for public safety with the protection of individual rights. This concept also establishes the legal foundation that allows officers to investigate suspicious behavior while respecting constitutional protections against unreasonable searches and seizures.
