Most martial arts teach a sport-based system of fighting. Judo, Karate, Jiu-jitsu, Tae Kwon Do – they all teach a system of points and moves that, while excellent for fighting in the classroom and tournament, have little or no value in a real life-or-death situation.  Self-defense is not a sport, it is not fighting. Self-defense is exactly what it says: defending your self.  Real self-defense is a multi-layered concept that includes learning and understanding what a criminal needs in order to succeed at crime, how to deny him those important elements, and giving you tools to help you stay alive during the most violent moments of your life.  It involves Common Sense, Negotiation / Diplomacy, Reasonable Force / Timing and Tactical application.
