BTW, I don’t own a gun and have not ever owned one since I was a kid and briefly had a hand-me-down .22 rifle from my father’s own childhood, until it started malfunctioning. But I’m actually not sure that the use of guns here resulted in more harm than what could easily have happened without any guns present. If I had been driving, I would have been freaked out and definitely would not have gotten back out of the car—but I would have gunned it to get out of there, which may have seriously injured the woman behind the car.
ETA: I always, if at all possible, park in such a way that I don’t have to back up to get out. My wife considers this a little paranoid, but it would have been good in this circumstance. If someone’s trying to block your way, much better to have them in front of you.
