What type of pressure is applied to the side of the subject's neck using an officer's wrist?

The correct answer, which identifies the type of pressure applied to the side of the subject's neck using an officer's wrist, is compression pressure. This type of pressure involves applying force directly onto a specific area with the intention of controlling or incapacitating the subject. In the context of law enforcement and restraint techniques, compression pressure is utilized to effectively subdue an individual while minimizing the risk of injury.

Compression pressure is characterized by the way it targets the tissues in the neck area, impacting not just the skin but also the underlying muscles and potentially blood vessels or nerves. This method is strategic, as it can influence the subject's physiological response, making it a crucial element in certain control techniques.

Other terms like simple pressure and complex pressure may not accurately define the technique used in this context. Simple pressure generally refers to minimal force applied without a specific target area, while complex pressure might imply a more intricate application that involves multiple areas or techniques, which does not align with the straightforward method of using the wrist on the neck. Therefore, recognizing compression pressure helps in understanding the application of force in effective restraint methods within law enforcement protocols.
