I hope answered them.
I see where you are coming from. As martial artists we show restraint in our actions even self defense because we hear horror stories about the legal bulls**t that innocent people have to deal with.
Exactly, and thats the reason why I started some threads (they should be in the General SD area) about being afraid to use your training and what you can/can't do in your training. Hey, we all train for various reasons, but for me, its SD. Yes, i get the benefits of the 'side stuff', ie: exercise, meeting new people, etc., but thats not the only reason I train. If someone wants to try to sue me, because I defended myself...after they tried to rob me of my belongings at knife point, then good luck to them. But I'm not worrying about that at the moment.
The above is just my opinion. Some will agree and some will disagree. To each their own.
