There's a whole website preaching that sort of vandalism.

Our Rules & Guidlines for Successful and
Ethical Big Game SUV Tagging:
1. Only tag the big ones. The Ford Expeditions and Excursions (I avoid the Explorers), Chevy or GMC Suburbans, 1500's, 2500's which often go by the Yukon and Tahoe name. The Cadillac Escalade, Toyota Land Cruiser, Land and Range Rovers and Lexus LX470 are all to be considered targets of opportunity. It is best to tag in the affluent suburbs where you will notice the Urban Assault Vechicles are never dirty. I figure that most people in rural areas are probably using them for a functional purpose and therefore don't tag in these areas.
2. Do not tag small SUV's such as any Suburu, Toyota 4Runner, etc. Owners of these small and reasonably fuel efficient SUV's keep complaining to me when they are tagged. We are after only the grotesque and bloated gas guzzling members of the SUV species.
3. Don't tag commercial vehicles, contractors, or any business affiliated vehicles. Also no pickup trucks. We have no gripe with people who really need these gas-guzzlers. It's the morons who are keeping up with the Jones' that raise my back hairs.
4. Don't retag vehicles that you recognize as already tagged (we can usually spot left over pieces from the original tagging).
5. We only tag late model vehicles, not some beat up old Suburban some poor soul has inherited.
6. Don't tag just because it's a four-wheel drive vehicle. Only the really big obnoxious ones.
With these restrictions there is still an unlimited number of eligible vehicles.
SPREAD THE WORD AND CHANGE THE WORLD!
Because going out and doing something useful with their time, like cleaning up trash and litter from a river or similar, would be too messy. Plus it's hard to feel smug when you're up to your armpits in trash.
I have animal magnetism. When I go outside, squirrels stick to my clothes.
