This story is bogus. DOD does not keep things like this secret. If something like this occured at all, the matl's were taken prior to US forces knowing about the pile and the USDOD has no reason to beleive the claims are true. Otherwise the story consists purely of accusations, rumor and other purely contrived rubbish.
Here's a fact: Most of the IEDs exploded, or discovered in Iraq are derived from, or are rigged munitions themselves. They are rigged ordnance, not raw HE.
Also, it is officers on the ground in Iraq that are responsible for these sort of things, not Bush, Cheney, or Rummy. THey didn't cover up Abu Garab(sp), failure to protect the antiquities in the museums, and they aren't covering up anything else.
Rats rely on BS to get anywhere, that's all this is.
What's been covered up has been John Kerry's military records and Teresa's tax records. The information contained in those documents would fill front pages of papers-- even liberal ones-- for months.
