You know ItsThaMonsta INVENTED the "driving-with-your-jimmy-out-the-window" technique, and as a loyal believer in this technique, I wouldn't hesitate to whip out my jimmy and piss all over that *******s's face for pulling that ****.
I parked my motorcycle outside in my GF's (at the time) apartment complex. My bike was pissed on, knocked over, baseball batted, and had my turn signals ripped out of their stalks within the course of a year. This was in a "good neighborhood" and the bike was parked in a highly visible spot.
It can happen anywhere really.

Worst part is that there is nothing one can do unless you catch them doing it.
Mostly, it's sad that others' lives are so ****ty that they would take their frustrations out on other people's property... RESPECT MY AUTHORITAAAY!
