a) "From three Iraqi defectors [we know] that Iraq, in the late 1990s, had several mobile biological weapons labs. These are designed to produce germ warfare agents and can be moved from place to a place to evade inspectors. Saddam Hussein [has not disclosed] these facilities. He [has given no evidence] that he has destroyed them."

Comment: What we "know" is that defectors make this unproven claim. We don't know if they were paid or coached to make the claim, or volunteered it on their own. For more on this, see Point 9 of the analysis of Powell's address by Dr. Glen Rangwala, Lecturer in Politics at Cambridge University, an advisor to Labor Party opponents of Tony Blair and perhaps the world's foremost authority on U.S. claims about Iraq, which may explain why one never sees him in the U.S. media. http://www.traprockpeace.org/firstresponse.html

Rangwala notes that one defector made no mention of the labs in his first press
conferences. It was several months later, after "debriefings" by the U.S. and the Iraqi National Congress, that he started talking about mobile labs. Hans Blix told the Guardian newspaper of Britain he has seen no evidence that these mobile labs exist. http://truthout.org/docs_02/020603A.htm
