A Carjacker Tries To Steal A Guy's Motorcycle, But Another Guy Gets Out Of His Car And Shoots Him

It's not clear when this happened, but there's helmet-cam footage making the rounds of a guy on a motorcycle, apparently in Brazil.  And he gets carjacked at GUNPOINT.

But right when the guy with the gun is about to ride off, another guy gets out of his car and SHOOTS HIM.

According to one report, it was a cop who wasn't in uniform, and the thief ended up dying.  But he's definitely still alive throughout the video.
