Errol Morris Confidential Pt 2 of 2

I continue interrogating the interrogator in this second of two wide-ranging conversations with filmmaker/detective/truth-seeker Errol Morris. Among the many subjects discoursed on: Whether and how much the past can be recaptured through the art of investigation; Errol's latest book "A Wilderness of Error," about the Jeffrey MacDonald murder case; how he gets people to spill the beans on camera; Errol's beef with his former PhD adviser, historian of science Thomas Kuhn; and his next movie (The Fog of War with more fog?).
