Jay Rosen has a superb piece online about how Murray Waas is much more important and a more useful journalist today than Bob Woodward. Rosen even goes so far as to dance around the claim that Woodward isn't really a journalist anymore, but rather an insider.
I mostly spend time with much lesser journalists. What I've noticed is that there is a pervasive phenomenon in DC, where many journalists consider themselves to be closet strategists and independent truth-tellers. That doesn't hold up! What Murray Waas does is structurally different; Waas pores through documents, learns everything there is to know, and works his sources. Murray Waas is truly relentless.
