Fifteen Years after the Oklahoma City bombing, Rachel Maddow brings viewers the inside story on the deadliest terror attack on U.S. soil prior to the evens of September 11.  For the first time we hear Timothy McVeigh's chilling confession in his own words.  He never admitted his crimes to the FBI, the courts or the media - except for a single series of interviews that have never been heard publicly-- until now.  Drawing from 45 hours of never-before-released interview audiotapes recorded while McVeigh was in prison, the film reveals the bomber's descriptions of the planning and execution of the horrific attack and goes deeper than ever thought possible into the mindset of this calculating killer.  The two-hour documentary employs recreations and graphic simulations, including new facial replacement technology that dramatically depicts the events of McVeigh's story.  Nine years after his execution, McVeigh's voice from the grave resonates today with the rising tide of anti-government extremism.
