How would you react? What would you do?
This was my reaction. I live in a constitutional carry state, where stand your ground exists. And I have a concealed carry permit. I pulled my gun out of its holster while he was walking to my car. I rested it on my leg plainly visible, my hand on it, my window was already down. And when he got to my car, I politely yet firmly stated "perhaps you should reconsider your life choices." he said nothing, the color drained from his face and he returned to his truck and drove off. I did not point it at him, nor threaten him with it beyond having it out. In honesty it scared the shit out of me that he chose to do that.
