thats farked! That actually happened to me last summer. Local carnival, walked out to see a bunch of mexican teenagers emptying their trash, ashtrays, gross ass half empty bottles of who knows what. So i took a quick mental pic of the vehicle (blue tahoe with gangsta rims), casually walked to my jeep, got in, took off and tailed them at quite a distance until they stopped at a apartment complex and got out. I rolled up the street a bit, pulled a trashbag from my toolbox, put only their trash in the bag, walked to their tahoe and destroyed the back window and put their trash in the back of it with a you dropped this back there note . Drove away with a huge grin.
yay!
