I saw what a 3rd dan black belt could do to someone when he defended himself when four men jumped him one night, he did not give warning he was well trained in combat arts, he did not give warning he was trained in counter battle planning, All that was intended that night was several people wanted him humbled, I am talking about my husband, he did not back down from a request from someone in a higher societal position than him, I fact the level and language used was insulting, One man was transported with both eye sockets shattered, another was thowntwenty feet into the street where he landed wrong an broke an arm and both legs, I saw another with his arm so twisted it looked like it was attached upside down. and the fourth my husband used his elbow driven into his chest so hard it stopped his heart. My husband walk away with a small bruise, Is standing up and not backing down worth this kind of damage to other human beings?
