Back when I was in martial arts school they always made a big deal out of never using it unless you were being attacked on the street? And even if you WERE being attacked on the street while you were still minding your own buisness, cant you be charged and go to jail for assaulting the person back? And thats what I find absolutely ridicuolous is that self deffense is a felony, but why does karate and other martial arts teach you such destructive things you can do to a person when you cant touch them anyways? Like.... I remember learning how to make someones heart beat stop and such.... Only asking because i'm interested in MA and would like to know.
