In criticizing media priorities and biases we often draw on the media themselves for at least some of the facts. This affords the opportunity for a classic non sequitur, in which the citations of facts from the mainstream press by a critic of the press is offered as a triumphant "proof" that the criticism is self-refuting, and that media coverage of disputed issues is indeed adequate. That the media provide some facts about an issue, however, proves absolutely nothing about the adequacye or accuracy of that coverage. The mass media do, in fact, literally suppress a great deal, as we will describe in the chapters that follow. But even more important in this context is the question of the attention given to a fact -- its placement, tone, and repetitions, the framework of analysis within which it is presented, and the related facts that accompany it and give it meaning (or preclude understanding). That a careful reader looking for a fact can sometimes find it with diligence and a skeptical eye tells us nothing about whether that fact received the attention it deserved, whether it was intelligible to the reader or effectively distorted and suppressed. What level of attention it deserved may be debatable, but there in no merit to the pretense that because certain facts may be found in the media by a diligent and skeptical researcher, the absence of radical bias and de facto suppression is thereby demonstrated.
