re: if it was so dangerous why isn't Bush saying so?
"He would have been crowing about this in a speech by now. He did that with the trailers of death and they didn't even know what they were. If there was a chance this was a big find I'm sure they would be telling us all about it. "
Bush wants to focus on finishing the conflict and make it possible to quickly return power to the Iraqis.
And making a big deal about some detail in Kay's report would run risk of making it appear the work was completed rather than being a progress report.
