I'm hoping this guy broke his hand. I actually know someone that did the same basic thing, punched a driver's side window multiple times. (some teens drove really obnoxiously to the guy with his new baby in the car). It resulted in him breaking one of the bones in his hand, presumably on one of the punches and then punched again which caused the broken bone to pierce the skin on the back of his hand (small puncture wound). So he ended up scaring the crap out of the kids, but also ended up with a compound fracture of his hand (and he worked in IT so did a lot of typing for a living).
