the documents that convinced Mr. Kay that Saddam had weapons of mass destruction remain a closely guarded secret, with a team of 200 Pentagon analysts reportedly still sifting through their contents.
Don't they answer their own question?
What happened to the internal Iraqi government documents that top U.S. weapons inspector David Kay said had convinced him that Saddam Hussein had weapons of mass destruction?
In January 2004, Kay told Congress that the U.S. was "almost all wrong" in believing that Saddam had WMDs.
But six months earlier in July 2003, Kay said he was sure Iraq had the banned weapons - based on millions of pages of internal government documents recovered from Saddam's regime.
"I've already seen enough to convince me," Kay told then-NBC anchorman Tom Brokaw. "You cannot believe how many cases we have of documents and equipment that are stored in private residences," he added.
