This has got to be the worst attempted robbery we've ever seen. The video above shows a man catching a thief in the act of clipping the lock off of his bike and flipping his camera on to confront him, only to get threatened and told to leave. The guy is obviously not trying to fight for the bike and instead tries getting nearby security guards to do something, but to avail. Luckily, the thief decided to leave without the bike, but not before decking the cameraman one time for trying to keep him from leaving.
We're not entirely sure what the moral of this story is yet.
