have you seen Starship Troopers? remember when the recruit tries to say that knife fughting is useless? taht is how u need to like at martial arts. unconciousness or death renders all technology useless. there are no dangerous weapons only dangerous men with weapons. people get killed running away all the time. u cannot out run bullets either. if attacked i will do my best to kill or maim my opponent (depending on the situation). agression is not the answer but neither isd passivioty. after all if i fight i will probably have the oppurtuniyty to run, but not the other way around. pick what fits the situation
