Even if the graffiti perpetrators think they have some talent, what makes
them think it's legitimate to impose their designs on someone else's
property, which the owner has decided will be painted in a particular
colour? What really annoys me are graffiti vandals who destroy the quiet
dignity of a brick wall that has stood for perhaps 130 years serving the
people of London. I don't care whether it's a mere tag or something more
elaborate and colourful. It's still criminal damage. Please don't be
tempted, Robin, to give the criminals the recognition they crave by
photographing their mutilation of our environment.

You assume that the artist did not get permission from someone
authorized to give it. While I have no doubt that they normally
do not get permission, I rather suspect that this isn't univeral.
