If you can leave the situation do it. To many people carrying a gun with all these civilian carry permits feel like an 800lb. gorilla and actually escalate problems being a "tough" guy. Stand your ground laws should only be for Police Officers in their legal pursuit of their goals. A civilian with a gun should have to retreat at first resort if possible. Stand your ground and kill someone when you could have walked away is insanity.
YES! I got my permit (must have been 1997 or 1998) and they trained us "DUTY TO RETREAT" - Always make an effort to de-escalate. I love it and live by it. I've been punched in the face, while packing heat, and I retreated.
NOW? I went to a CCW permit course last year and it was all "When am I legal to shoot someone" and "you don't have a duty to retreat." It's changed a lot. Unless my back is to a wall and I can't move an inch... I'm creating space, obstacles, and a way to escape a situation before bullets start flying. If I come home - and my door is wide open - I"m calling the police to sweep it, not walking into 4 dudes with shotguns hiding in the bathtub lol...
Too many people love that confrontation, lusting for trigger time. Not for me!
