You would think somebody wouldn’t aim at the car door. But maybe they’re just really bad shots. You’d expect going thru the door to cause the bullets to lose considerable velocity.
You would think, but that isn’t an option for these thugs, it’s action first and think ...no I doubt that.
Most cars have a formed beam in them to protect you from a side collision. Heavy gauge steel, like a guard rail.
Someone shot at the cab my brother was in in Oklahoma once in the 80s, went right through the door like it wasn’t there and out the other side, fortunately he just felt it whizz past him. That was random, though.
