Blogistan is all-a-flutter about the story about how CNN didn't report on a lot of Iraqi atrocities in order to preserve their access and protect their sources (see the Volokh Conspiracy for a variety of commentary/links on the subject). The assertions by some that this is a case of the "liberal" (hah) CNN covering up for a murderous dictator because- well, because us liberals love our murderous dictators - are of course ridiculous. I have no real opinion on whether they did the right thing on balance - I don't really have enough information to know.
However, I'm glad some republican types have come around to the idea that a news agency might compromise the truth in order to preserve its access and relationships with its sources.
