If there are any people who know about the WMD beside Saddam of course, you can find them on the list you just showed and they are still at large unfortunately. From my reading of the Iraqi documents, I can tell you that the director of the Special Security Organization and the Director of the Intelligence Service are without any doubt aware of what happened to the WMD. In fact the Chemical Weapons were solely handled, hidden, and delivered to the battlefield by the Special Security Organization which was headed by Qusay Saddam Hussein.
In regards to Saddam Hussein, I am sure that our interrogation tactics are a joke for him and he basically gave us little to no information about any important subject, specially the WMD.
I wonder why the "search for WMD" became a low priority. The administration is dogged by this and it makes it so much harder for them to get anything done when the just accept this and move on.
I know they are serious about not blowing their creditability by jumping on some bogus "find." But at the same time, the evidence is stacking up that Saddam was really building a Terror network and really working on WMD with an eye toward having this capability to effect world events.
Now, if these guys know where the "bad" stuff is hidden and how to use it, is it possible that they can access this stuff and make it available to attack us now?
