Intelligence stated about credible evidence, that all the 3 videos (including the black glassed one)released after the attack of Saddam were recorded in same room and in short intervivals, bossibly days before the bombing happened. I heard something about same dirt stains visible in all of them and something else too. They said, that only the arrangement of furniture was changed in between the recordings.
Its really strange, that in this time of speculation and need for rallying his people this man doesent make any unspeculative appearances. It wouldnt be that hard, just having couple of time-and-place statements included would end all speculations.
