Well the long and short. Anyone carrying a weapon is obligated to avoid an situation that would require its use. First lesson taught in gun training. You use it, you will be charged with murder till they sort it out. He was carrying, he needed to stay in the car and let the cops handle it. Just cause you are carrying ya can't walk around a drug neighborhood in an inner city with twenties sticking out of your pocket so you can use your weapon. You are duty bound to avoid that stuff. It is legal to carry a firearm in a bar, but no one I know that would go into a bar with a weapon. Ya just don't do it. That thing is to be used only to save a life, your own or others in a situation you cannot avoid
