Unverified reports have been suggesting that Saddam might have been a casualty of the heavy bombardment of Baghdad. Even if US troops kill Saddam, I believe they should never let the word out. The moment the US kills Saddam and makes a big news item of it, he will ensure his place in Arabic History books as a martyr for the Arabic cause.
With the shrewdness he has, he might have already recorded a video, to be broadcast in case of his death in war, portraying him to be a victim in the hands of the Cruel west. The West, who attacked his country and killed him, even when he didnt have any weapons of mass destruction. Importantly the video will stress on the arabic cause, to strike a chord in Arab hearts, by showing how he died defending his nation against Western crusaders.
