Which technique involves mirroring the controlled hand and sweeping it behind the subject's back?

The technique that involves mirroring the controlled hand and sweeping it behind the subject's back is the hammer lock transporter. This maneuver is designed to exert control over a subject by locking one of their arms behind them in a way that limits their mobility and ability to resist.

In executing a hammer lock transporter, the officer utilizes the subject's own arm and body positioning to achieve control. This technique not only immobilizes the arm, but it also serves to reinforce the subject's compliance through the application of pressure at the shoulder joint. The effectiveness of this technique lies in its ability to maintain control while allowing the officer to position the subject safely for further processing or restraint.

Understanding this technique is crucial for practitioners in the field, as it emphasizes the importance of using leverage and body mechanics in apprehending and controlling subjects, thus minimizing the risk of injury to both the officer and the subject. This contrasts with other techniques that may focus on different methods of control or immobilization, providing officers with a variety of strategies to adapt based on the situation.
