The thing with the Killian documents case is that, while CBS (presumably) didn't knowingly run a false story, they were very negligent in their sourcing and verification. They wanted the story to be true too much. [ADDED: We don't know at this time whether the same can be said of Bloomberg, assuming the story unravels.]
Other news organizations were also pretty mad at CBS over this. There was a story around W's National Guard service that actually didn't depend on the Killian documents. But once those documents were determined to be fake, it pretty much blew up the reporting around the story generally.
