During a Terry frisk, which action enhances officer control?

In the context of a Terry frisk, having the subject keep their hands behind their back significantly enhances officer control during the encounter. This action minimizes the possibility of the subject reaching for weapons or other objects that could pose a threat to the officer's safety. By controlling the subject's hands, the officer can more effectively manage the situation and ensure a safer frisking process.

Furthermore, maintaining a controlled environment allows the officer to maintain spatial awareness and react quickly should any unexpected movements occur. This action demonstrates to the subject that the officer is taking safety precautions, which can also help to de-escalate the situation. Additionally, it provides the officer with a better position to monitor the subject's behavior and any potential noncompliance.

This context is vital because it directly impacts the efficacy of the officer’s procedures and their overall safety during an encounter where there may be suspicion of criminal activity.
