This has been discussed on a couple internet forums already. It's been proven to be a fake staged video. Watch the camera man when the guy pulls out the gun...he zooms in on the gun. Not really the reaction of a scared man. But anyway, good laugh and entertaining video...
It was on INGO recently. IBTL!!
If anyone has evidence this is staged I'd like to see it. Passenger zooming in on gun isn't enough for me since the gun's pointed at the driver, not the passenger (who was videotaping). I know there's a lot of argument over whether nor not this is staged and I'm not convinced either way yet.
