Another Beheading on Videotape?

A foreign Web site is supposedly featuring videotape of a man with a sign around his neck identifying himself as American, possibly CIA, who is then beheaded with a huge ceremonial knife. But while three Americans are missing (and boy, do I doubt that number) including two civilians and one service person (which may be a fellow executed in another video, where he's shot to death but the Army says they can't ID him), the CIA says none of its operatives are unaccounted for.

I'd like to think this is staged, but I doubt it. Indeed, nothing in Iraq has seemed to improve since we "handed over" power on June 28th.
