I didnt click the link, but I did google the name and that wasnt it. This was out in some desert, middle of nowhere, bunch of Arab dudes getting all hostile, this American dude pretty stoic and not saying much who was literally hogtied.
The executioner/murderer was the camera operator. The American was kneeling in a hogtie, the exe/murderer kicked him over onto his side, got real close with the camera to the guys face, showed the knife, stepped on the side of his head, and plunged the knife squarely into the side of the guy's neck and then "sawed" his way out the front of his throat. Very loud, very strange sounds, shock, horror, you get the picture.
Last time I describe that.
