Sounds like the start of a disinformation campaign that got interrupted by the Liberation. 1st you write the offical documents, then you leak it to your tame stoodges in the Western Media. Remember what the ex-head of CNN admited to doing so he could keep the Bagdad office open?
To be fair, you can't really assign 1st/2nd to such a scheme, can you? Either they're hiding or they're not or the left hand didn't know what the right hand was doing.
There's also a simple answer as to why Bush never highlighted all this stuff....because it's an onion peeling contest......gets less and less clear the more you dig into it.
Thus, they may have chosen to ignore all the "proof" because by drilling down, all you do is hand the war-opposers more "evidence" that the case was not clear (which, really, intelligence never is.)
Imagine trying to divine what Idiot Kimmy Ill is doing right now. There's no telling how confusing the paper/intel trail of a psychotic leader is. How to discern the truth from the info/disinfo/crazy?
