Siddle's 3-point standard has been used internationally as a guide for use-of-force training programs for police and private security that are defensible in court. The Components of Acceptability state that to be court defensible, a use-of-force training program must meet tactical, legal, and medical standards of acceptability. Under these standards, all tactically acceptable physical control of defensive techniques must be supported by research which documents that they are easy to learn and retain. Tactically acceptable techniques must also be effective when used by security officers of any size, sex, or age and must work when used in real encounters on the job. Techniques should be simple and based on gross motor skills that use the large muscles of the body. These are easiest to retain and execute under stress. All techniques must meet legal standards for the acceptable use of force by security personnel. They must also produce predictable and reasonable results every time. Medically acceptable techniques are backed by medical evaluations and research that documents and predicts the result of the technique. Consistency in training program content and information delivery is important as is training documentation.
