all the reporters involved in this, and some other DC media insiders apparently. David Corn wrote about it, Andrea Mitchell made comments about it, Judith Miller has had long established contacts in CIA regarding WMD, Coopers wife is a high ranking Clinton advisor. They all talk to each other, the idea that they were all just a bunch of ignorant doofuses who just walked into this story, all knowing nothing - is simply not believable - except to Fitzgerald apparently.
You forget, Libby also assumed they were a bunch of doofuses and look who's been indicted for hiding behind a reporters shield.
