So, I'm just going to lay this out very simply, even though in the linked video, Olbermann appears to consider this too distasteful to do more than just touch upon (and indeed, there are bigger fish to fry first).

An "interview" is supposed to be a question and answer session between a reporter and the interviewee, right? So that the reporting is basically saying, "the reporter asked this question, and the person being interviewed gave this particular answer to that question", right?

So, in what lunatic alternate dimension does this become "an interview is a creative reinterpretation of what we think we'd like this person to have said in response to these questions" and make Katie Couric's interview session with John McCain, as aired not a massive breach of journalistic integrity because basically, what they aired showed McCain giving an entirely different answer to the question asked about the troop surge.

In short, what CBS aired was decidedly fiction and "news" is supposed to be non-fiction.

So, doesn't CBS believe in 'journalistic integrity'?
