We had something similar overhere. A magazine parked a car near a soccer stadium and informed some of the hooligans were to look. The car had stickers, caps etc from the opposing team and subsequently thrashed by the hoolies.
When people found out that it was a set up just for kicks and not news.... well the magazine never got over it and now it has the label of "gutter-journalism" and not taken very seriously anymore. In short: what comes around goes around!
