Hey folks get real. The guy is 10 ft away. How close is acceptable. She didn't know him, gotta believe he was bigger than her, flimsy excuse to get closer and yea I would probably done the same but kept quite and not pointed the weapon directly at him until I was sure he was coming closer. I'm in my 70's, can't run or jump anymore and I'm not going to be a victim. I had rather take my chances in a courtroom than in a parking lot. If it were my wife, I would be giving her accolades for her vigilance.
10 ft and closing leaves no time to guess what he's up to, give the lady a break and try to put yourself in that predicament. Her reaction could have been different but the action she took may have prevented something a lot worse than facing a jury. You gotta hold the guy responsible for doing stupid stuff.
