Interesting post, I guess it's because graffiti is out there for all of us to see in good areas and bad areas. Most of us don't on a regular basis come across members of the oldest profession or have been in a bank during a hold up so it's more of a problem that really doesn't affect us. Graffiti is more of an in your face kind of thing, done more to let someone know that even tho this belongs to someone else I'm laying claim to it and there's nothing you can do to stop me. And the more we become outraged at a particular individuals "art" the more his street cred goes up and the cycle continues.
