ju jitsu is what they taught us in law enforcement school....
short story...
one of the sargeants (little guy, 'bout 5'7" and 165 lbs) for the Game Commission in Florida (Jacksonville area) was almost a master in ju jitsu...whenever the deputies came across any of the good old boys breaking the game laws and they were arseholes, they would call this sargeant...he would show up, the good old boys (be it 3 or 4 of them) would get all macho and stuff and before you knew it, the sargeant had them all on the ground cuffin' them...he was a true BAD A**
