The old man is 61 and can claim that he thought the middle finger was a weapon.
Hey, I’m 61 and have an IMPEACH OBAMA sticker mounted on my truck bumper.
To date, I’ve not had anybody flip me the bird.
I doubt that the 9MM BEATS 9-1-1, EVERY TIME sticker on the other side of the bumper has anything to do with that, either.
Six year olds pointing fingers get suspended from school for having pretend weapons so it's not a stretch or him to claim he thought he was being threatened. Same thing.
