Many of you have demanded I retract my criticisms of the Bush administration’s handling of the explosives cache at al Qa Qaaa. If the facts really do emerge that these materials were removed before or during the invasion, I will. But the evidence is far murkier than that and points predominantly in the direction of U.S. negligence. Marshall has the best summary. Two things stand out for me: David Kay believes the stuff was looted after the invasion; no news crew, like NBC’s, would have had the capacity to check the inventory of a plant hundreds of buildings big. But if the facts change, I’ll respond.
