Street art: do they have to catch you in the act?
Just wondering. Do police need to catch you in the act of putting up street art in order to charge you, or can they charge you after the fact?
eg. for those artworks that Banksy has signed his name to, is that proof enough that he made them, and could he be charged if he was exposed?
