This is the most reasonable explanation of what happened. The logistics of insurgents making off with 380 tons of material after American troops took control of the area never made much sense. In drawing attention to the possible movement of weapons prior to the war, the MSM might have opened a can of worms, i.e., if Saddam could move and hide 380 tons of explosives, he could move and hide WMD's.
This story gives me hope.
Consider: these pic's are not new. A reactionary overzealous president may have been tempted to run this type of information out during the, "you lied about the WMD", hype.
Instead, they can be used (can't wait to hear the cover story on the source) as helpful information to "investigate" the timing of the weapons disappearance.
