I practice Hokutoryu Ju-Jiutsu (´police´jutsu) trained to special forces and law enforcement agencies worldwide.<br/><br/>Krav Maga has its roots on HJJ, but its more simplified, HJJ focus on subdue holds/locks and chokes, baton/telescopic baton and knife. We have some gun-fu taken from krav maga, as most of our dojo, work on security field. There is police officers, bounchers, private security guys, MMA practioners and me (computer upkeep geek´ess)... For some reason I have never got any trouble getting into clubs and bars in our town, and in those clubs/bars I have never get harashed :)<br/><br/>but true, 13-16y is lousy age group.. but.. as I´m turning my uber naziness on them, I´l sort them out.. cant really beat them to submission, but there are ways... *thinks of making them run laps for ten minutes before each session.. and then sparring for another ten... muhahahahaha (patented world domination laughter).. my minions....*
