On topic, I just watched Today Tonight (my soul eroded a bit) and there was a segment on graffiti in Melbourne and move to protect some of the walls. They started the report with a bunch of yobbo kids scratching windows on a bus and then linked it to the street art like this, suggesting incorrectly that "one day" the kid's vandalism could be protected.

Despite the fact that they are completely different, they managed associate them.
