Which pressure point technique is best when wanting to make a prone subject comply?

The technique involving the elbow under the shoulder blade is particularly effective for making a prone subject comply because it targets a sensitive area that can induce significant discomfort without causing injury. When pressure is applied to this location, it creates a controlled leverage situation that allows the officer to maintain control over the subject while minimizing the use of excessive force. This technique can also ensure that the subject is oriented in a manner that limits their ability to resist further, as the pressure can cause discomfort that motivates compliance.

In contrast, the other choices may not provide the same level of control or efficacy in a prone position. For instance, applying pressure to the hollow behind the collarbone or under the jaw may not have the same immediate effect on a subject who is already on the ground. The hollow behind the ear, while also a sensitive area, may not be as practical for compliance in a prone scenario, as it’s more useful for situations where an officer is directly controlling the head or upper body of the subject. Therefore, the elbow under the shoulder blade stands out as the most effective option for ensuring compliance from a prone individual.
