Jbb, where do you live where there are fights in the street, thugs coming into houses, etc? I hope that MMA & TMA practicioners understand that fights are dangerous. I would say that in the states, at least in the south, more than half of households have firearms & if you show up & start hitting poeple you'll get shot. This is what would happen in my home, or my father's, my sister's, my brother-in-law's, etc. In urban areas there are guys who would just as soon shoot you as talk to you. If all they have is a knife, you'll be lucky. As many have said previously, the mind is your best defense. Stay out of situations and places (if you can) where things like this might occur. Just my opinion.
