Of course, upon completion of my suggested two-week long "interrogation," anything could have happened, could it have not? ;-)
Apparently, our people believe it was better in the long run to parade a cowardly, pussified Saddam in front of the camera, instead of this supposed "warrior" his supporters thought he was.
They're betting this does more to expose his legend as nothing more than a fraud to demoralize, and thus negating the "movement" instead of turning him into a martyr. It may make more sense.
