What is required to perform a Terry frisk?

Performing a Terry frisk, named after the Supreme Court case Terry v. Ohio, requires law enforcement officers to have reasonable suspicion that a person is involved in criminal activity and to believe that the individual may be armed and pose a danger to the officer or others. This standard is less stringent than probable cause, which is necessary for an arrest or a search warrant, but it still demands a specific and articulable basis for the suspicion.

The key component of the Terry frisk is the officer's belief about the safety risk presented by the individual. The purpose of the frisk is to ensure the officer's safety and that of the public while also respecting individual rights. The requirement for reasonable suspicion helps to strike a balance between effective law enforcement and constitutional rights.

The other options provided do not meet the legal standard established by the courts for a Terry frisk, as they either require a higher threshold of evidence or do not pertain specifically to the need for fear of imminent danger associated with a suspected weapon.
