Did anyone else notice that the Humvee with the camera where thisiskeith12's brother supposedly is, is not a Humvee at all? If you look closely at the windshield, slope of the hood, and dark reflective paint, it's obvious it's a GMC Suburban type vehicle similar to the civilian vehicle ahead of it.
FYI.. I asked a good friend of mine who served in Iraq to view this video and he has seen it several times and tells me it was indeed taken by Blackwater contractors. Backwater contractors can occasionally get away with taking camera footage while "on the job" but for US soldiers to do the same it would often result in severe reprimand. You simply don't whip out a camera and start filming your surroundings during a dangerous escort mission when you should be manning your weapon at all times.
