Looted explosives? Or not?

Some right-winger commented on yesterday's story about missing explosives in Iraq, saying that NBC had already debunked this, sarcastically thanking the NYT for their unbiased reporting. Silly NYT, believing any little drug-addled informant that whispers lies and half-truths to them! Oh, plus the International Atomic Energy Agency. And, the Iraqi government (from CNN):

Earlier Monday, the IAEA revealed it had been told two weeks ago by the Iraqi government that 380 tons of HMX and RDX had disappeared from Al Qaqaa after Hussein's government fell.

In a letter dated October 10, the Iraqi government told the IAEA the material disappeared sometime after Hussein's regime fell in April 2003 "throughout the theft and looting of the governmental installations due to lack of security."

"Therefore, we feel an urgent updating of the registered materials is required," Iraq's director of planning, Mohammed Abbas, wrote.

Okay, I'll admit that just because those organizations should know what they're talking about doesn't prove that they actually do. But this still doesn't look like an open-and-shut case to me. How about this, from the AP via ABC:

At the Pentagon, an official who monitors developments in Iraq said U.S.-led coalition troops had searched Al Qaqaa in the immediate aftermath of the March 2003 invasion and confirmed that the explosives were intact. Thereafter the site was not secured by U.S. forces, the official said, speaking on condition of anonymity.
