It is important to control the subject's perception of the officer or agent. In our experience and research we have defined it in the following categories.
Three Types of Communication
The officers appearance (uniform, equipment), approach, gait, posture, eye contact, attitude and even pace and mannerisms are factors in non-verbal communication with a subject. Remember the subject is assessing or "sizing up" the officer as much as the officer is assessing the subject. At a primal level, they are weighing their ability to resist, escape and usually, ultimately avoid pain.
This is where VERBAL JUDO and TACTICAL COMMUNICATIONS training comes in. From showing empathy to making clear the consequences of actions and providing options to "save face", these are critical skills of persuasion.
This is the hands on step. Make no mistake that it is still negotiations and communication. The key is to communicate clearly to gain control and compliance of a subject. My first Martial Arts teacher was a ROK Marine who served in Viet Nam. He put it simply, "Some people understand this" (pointing to his mouth) "and some people only understand this" (holding up a fist).
In the world of psychology it is referred to as negative reinforcement, that is, pain is removed or reduced when you do as the officer wants. The removal of pain is the "reward" or reinforcement.
• The removal of a discouraging stimulus associated with a particular behaviour with the result that it is more likely to be repeated
When the verbal skills fail, kinetic skills take over and the persuasion begins by using varying levels of pain. The more skills an officer has in this arena, the more effectively he or she can subdue a subject.
The key to effectiveness on the streets is the seemless integration of these skills and developing the judgment of knowing when to move and use each. The mastery of these skills comes from a combination of training, maintaining and application experience.
Keep sharpening your skills.
