Of course someone going to die doing urban eventually, I'm sure someone has. Injuries will probably increase after the olympics. This is the same thing the kind of shut down freestyle in the 70's. There were like 3 different tours all running on national TV before people started getting hurt and then insurance shut it all down.
Thankfully right now it seems like most people hitting sketchy urban like Nipwitz know what the fuck they are doing, but I'm sure someone is going to die in the future.
