This isn’t merely the practice of journalists; rather, as Rosen points out, it’s virtually their religion. They simply do not believe that reporting facts is what they should be doing. Recall David Gregory’s impassioned defense of the media’s behavior in the lead-up to the Iraq War, when he rejected complaints that journalists failed to document falsehoods from Bush officials because “it’s not our role“ and then sneered that only an ideologue would want them to do so (shortly thereafter, NBC named Gregory the new host of Meet the Press).
