This week on Dialogue at the Wilson Center our guest is Mark Mazzetti, a Pulitzer Prize winning reporter for The New York Times. He is the author of the new book, “The Way of the Knife: The CIA, a Secret Army, and a War at the Ends of the Earth.” We also spoke with Curtis Brainard, Editor of The Observatory, the Columbia Journalism Review’s “lens on the science press,” to survey the landscape of science journalism.
