We have a news media that is psychologically ill informed but politically inflamed, so it naturally leans toward political explanations. We have a news media with a strong distaste for Sarah Palin and the Tea Party movement, and this seemed like a golden opportunity to tarnish them. We have a segmented news media, so there is nobody in most newsrooms to stand apart from the prevailing assumptions. We have a news media market in which the rewards go to anybody who can stroke the audience’s pleasure buttons.

I have no love for Sarah Palin, and I like to think I’m committed to civil discourse. But the political opportunism occasioned by this tragedy has ranged from the completely irrelevant to the shamelessly irresponsible.
