Delightful Inconsistent

There is a really groovy artist in London known as "the chewing gum man," because he specifically goes around flattening out chewing gum people have stuck to sidewalks and railings and buildings and then painting on that so that he can make the legal argument that he is not defacing the property because he is painting on the chewing gum, which he did not place, rather than on the public property. He's been roughed up by cops for it, but he is a local hero.
