The Universal Rule of Self-Defense Methodologies
All Self-Defense Methodologies are essentially Problem Solving Systems whose solution is to deprive an aggressor of his or her Intent and/or Means and/or Opportunity to do harm with in a framework of legal considerations and consequences. The Point of View of the Problem Solver influences which System he or she will choose.
All of these Systems are made up of a distinct set of variables that can be divided into Considerations, Assumptions, Factors, Problems, Outcomes, and Solutions that all incorporate legal aspects. The Solutions are a subset of the Outcomes. The Outcomes are a subset of the Considerations. The Factors, Assumptions, and Problems are also a subset of the Considerations. Therefore, the Considerations are the variables.
SELF-DEFENSE SYSTEMS = SELF-PROTECTION SYSTEMS + LEGAL ASPECTS
SELF-PROTECTION SYSTEMS = SELF-DEFENSE SYSTEMS - LEGAL ASPECTS
