Original post, 11:00 am Atrios reports the U.S. and Pakistan are that denying Bin Laden has been captured. He thinks the denial may be a lie.

If he's in custody, great. If they're holding back the announcement as this guy claims - not great. In fact - pathetic, despicable, disgusting, horrendous. Pooya said he heard of bin Laden's arrest from credible sources "who I have reasons to believe have never given me wrong information." He added he believed news of the arrest was being held back to coincide with the start of military action against Iraq . "All I know is that one of the things under consideration is when the announcement should come -- it's supposed to be timed with the apprehended attack between the 17th and the 18th (of March)."
