Then here's something a little sadder: this guys are more or less considered heroes. I've never seen the video, but I've heard the story from a tourist guide, who made it clear that this was an awesome stunt that should be admired.

Then again, keep in mind that Berlin has a rather complicated story with Graffiti (the city owes a lot to its starving artists), so the Western point of view is not the only one to keep in consideration.
