so some kids I go to school with fucked my car up a while back.
Shot it up with bigass airsoft guns [bbs the size of paintballs], rammed it, etc. While I was at a stoplight.

Called the cops.
They didn't do anything. This was 3 months ago.

Would it be bad form to ruin all their cars? They all just got their licenses, and their parents bought them the following:
1. 98 VW Jetta
2. 2006 Ford F-150 [about 3' off the ground at least]

I dunno what the other kid has. Both cars have about $3k in upgrades, which they did nothing to earn, their parents just don't know that they're a bunch of fucking stoner punks.

I wanna just key the fuck out of the cars and then when they get on my case just tell them what they told me: "Your car isn't even worth that much. Just buy some touch-up paint."

Thoughts?
