I think that was the point

In response to suggestions that the UN inspectors botched their jobs, given the mounting (indirect) evidence of Iraqi chemical weapons programs, Hans Blix has pointed out that’s only to be expected:

“The Americans have one advantage over UNMOVIC, in discovering things and that is as they go around the country and more areas are under their control it seems likely that people scientists engineers military will be more ready to speak to the Americans, than they were to us because when we were there they still had the formidable police apparatus that would scare them from saying the truth, if the truth was any different from what the government said.”

I … think that was the point of the invasion, Hans.
