If my (only) firearm is in my car and I can get to my car, chances are I will not be going back into the threat zone. If the gunman comes back outside in the open, i will be waiting. Hate to say it, but there is not a soul I work with that I would go back in for. If they chose not to arm themselves, NOT MY PROBLEM. Just like a fire, if I make it out, I am not going back in, not after I have made a way for me to be safe and see my family again. Sux, but that's just the way it is.
