"Hisownpetard," what an appropriate screenname, as the phrase originates with the idea of someone attempting to use an early type of breaching charge and through ineptitude or mischance being pinned to the target obstacle by his own charge when the fuse burns down and it blows both sapper and gate to pieces.
I doubt if the real AQ could restrain their more primitive urges long enough to actually conduct a waterboarding. If this fool ever looked at the videos the scum jihadists have put up on the net from the Chechen War or various other garden spots to 'glorify their struggle for Al'lah,' he'd know better than to post anything that stupid. If I were king for a day, everyone over the age of 12 would have to watch one of those horrifying videos so they would understand in their gut what we're fighting instead of worrying about the ****ing polar bears.
