Notwithstanding the current UFC craze, or people who have cross trained in ground fighting, BJJ, or boxing still may not have experienced a true self defense situation.
They may have stepped outside their comfort zone by participating in this training, pumped some adrenalin into the blood stream and got the heart pumping but the legendary fight/flight principle did not kick in because you had RULES to fall back on when things got dangerous.
There are no rules in self defense. Reminding me of the guy that took a 14" Bowie knife to the hood of my police car after kidnapping 5 kids.
Really made my anal sphincter tighten. I was able to disarm him with my police nunchakus that I carried at the time rather than placing 6 at center mass and causing tons of paperwork. The only rule I followed was the use of force continuum and the rule to go home to my family after my shift.
Perfect dojo kata will get you killed on the streets. Granted, it will help you on the street but not save you. What saves you is your street education and your fighting tactics.
Enough of a rant, stepping off my soap box...
