What does having visual control of a subject help to ensure?

Having visual control of a subject primarily ensures there are no hidden weapons. This means that the officer can monitor the subject closely, observing their movements and any potential actions that could indicate the presence of a weapon. Effective visual control allows the officer to assess the subject's behavior and the surrounding environment, which can help to identify any concealed items that could pose a risk to safety. When officers maintain visual control, they reduce the likelihood of surprises that might arise from a subject's attempt to conceal a weapon, thus enhancing overall security and safety during interactions.

While compliance, awareness of an officer's presence, and a secure area are important factors in a law enforcement context, the critical aspect of having visual control lies specifically in ensuring there are no hidden weapons.
