I appreciate the responses thus far eluding to the huge responsibility that comes with carrying a weapon.
I pray I never have to use my weapon in defense. My first line of defense is simply to try and avoid a situation if I can. Always have an out too.. I am always aware of my surroundings and try and have a plan for escape. If its just me and approached by a robber, I'll just give him the money and let him go. If its my loved ones and I fear they are in danger, it will get ugly.
