Last year, Justin Bieber got a little carried away with his attempts to do graffiti. However, it did get to the point where an anthropologist said that he had sparked a graffiti revolution across Colombia. After unfairly being allowed by Colombian police to spray questionable images in Bogotá, outraged Colombian street artists took to the wall and created over 700 pieces. He sprayed “Free Breezy” on a wall in addition to what looked like a Sambo portrait. It was a troubling time for anyone with respect for the art of graffiti to watch, but thankfully it's all over now.
