It could turn out that Loftus over-hyped his tapes for publicity reasons. Rick Moran has it right in his piece in which he quotes Lori Byrd thus:
If the tapes are authentic, the discussion of efforts to deceive the inspectors and to be ready to quickly resume WMD production is huge news, but it obviously will not be reported that way. As I said yesterday, it is going to take a heck of a lot to convince the media, and those on the left, that Bush didn’t lie about Saddam’s WMD. Scratch that. They already know he didn’t lie about it. It will take a heck of a lot to convince them to admit that Bush didn’t lie about it.
