In the Scaling Force DVD , Rory Miller and Lawrence A. Kane explain and demonstrate e full range of options during a violent encounter, from skillfully doing nothing to applying badly force. You will learn o understand the limits of each type of force, when specific levels may be appropriate, the circumstances under which you may have to apply them and e potential cost of your decision, legally and personally.
Level 1 - Presence. Staving off violence using body language alone.
Level 2 - Voice. Verbally de-escalating conflict before physical methods become necessary.
Level 3 - Touch. Defusing an impending threat or gaining compliance via touch.
Level 4 - Empty-Hand Restraint. Controlling a threat through pain or forcing or forcing compliance through leverage.
Level 5 - Less-Lethal Force. Incapacitating a threat while minimizing the likelihood of fatality or permanent injury.
Level 6 - Lethal Force. Stopping a threat with techniques or implements likely to cause death or grievous bodily harm.
It is vital enter this scale at the right level, and to articulate why what you did was appropriate. If you do not know how to succeed at all six levels, there are situations in which you will have no appropriate options. More often than not, that will end badly.
