So recently a group of assholes has been going around checking for unlocked car doors so they can steal shit. I'm pretty pissed off because they checked my wife's car (maybe stole a box cutter). I saw a group of 3 of them the other night, and later found out that 3 pricks got into the neighbors car, so it was most likely them. What can I legally do to cause as many problems for these assholes as possible? Can they sue me if I glue razor blades to the door handles?
