Better in a street fight?

Ninjutsu if you want to be really cool.
Capoeira if you like to dance.
Krav Maga if you want to win.
Smith and Wesson if you want to win and not get punched in the first place.
Avoidance if at ALL possible.
Chuck Norris if you'd rather just stay home and "have it handled"
The Police (aka Po Po) if you want to report who beat you up and that you would very much like a ride to the hospital

“If you ever find yourself in a fair fight, your tactics suck.”
