You know, i have watched that video a few times now, and each time it amazed me how calm Nic Berg was....almost as if this whole thing was some form of weird voyuer suicide....
He almost acts as if he is among friends........until the end.
I think that he didn't understand what they were reading when they said: this is revenge for showing how small the willies are on arabs.
I don't know the whole story, so I will leave my judement on Berg.
However, the story smellsssssssssssssss
Berg may have been calm in the video because his hypothetical Al Queda buddies told him it was just going to be a staged propaganda film to show that they had a prisoner. They may not have told him they were going to kill him. Maybe they said they would add in "special effects" work later to make it look like he was killed. Since in this scenario he was working with Al Queda, he would have had no reason to be scared until it occured to him they were really going to kill him.
