I would submit that this exchange, in fact, illustrates why we are screwed journalistically. The role of news journalism is to report the news, not offer comment or opinion or defense of one party or position over another. What you and your reader are pining for is opinion or analysis, which is fine for Jon Stewart because he's not purporting to be a news broadcaster; his whole job is to get laughs, so by necessity he gets to mock and deride and expose ridiculousness where it exists. This is most definitely NOT the role of a journalist.
The likes of Fox News et al are more than happy to conflate a particular point of view with what they purport to be straight news for the sake of ratings and profit. And worse, apparently this has become the expectation of a news broadcast for folks like your reader ... and seemingly yourself, which is somewhat surprising.
This is not to say that news journalists shouldn't challenge those in power to defend what they say and do; that's part of the role of a journalist and *that* aspect has been sorely lacking lo these past few decades. But they should issue such challenges from as neutral a point of view as possible, with no agenda other than to ferret out the truth of a given situation - not to get laughs or ratings or score political points.
You want opinion from Brian Williams? Wait for one of his interviews with Jon Stewart. Otherwise Mr. Williams is being entirely correct and professional by keeping whatever opinions he may have to himself during his broadcast.
