Art upon art

Some of the new street art adorning buildings in Dunedin's warehouse precinct and the surrounding area has been defaced with graffiti (vandalism pictured). On its online social media page, Dunedin Street Art says the group "clearly made someone angry" in its effort to bring art to some of the city's blank walls. The group posted four pictures of graffiti, three of which bore the same offensive stencilled message. One of the targeted buildings was Chipmunks, a children's adventure play business, and it's not something kids turning up to a play area should have to see. It’s also not fair to the artists or owners involved to have this happen to their walls. It’s Dunedin Street Art or the building owner that has to pay for such a bad-taste joke to be removed from the buildings. If someone is going to be tagging and defacing property they need to be caught and punished (and hopefully be made to reimburse whoever paid for the removal). What gives them the right to do that? And how would they like it if somebody went to their house and wrote things on their wall (like 'Get a job you talentless git')? The only silver lining of this is that the graffiti isn't actually on the street art - it's just on the same wall but not over the art itself, which is good because removal isn't going to destroy the work.
