On April 19, 1995, terrorism struck the heartland of America: A cataclysmic explosion destroyed the Oklahoma City federal building, took the lives of 168 people, and injured more than 500 others. It was not the work of a secret foreign cabal or a maniacal suicide bomber. Instead, death drove a rented truck, and behind the wheel was a young white American male with the barest of knowledge at his fingertips -- a driver's license to rent a van and a recipe for mixing farm fertilizer and fuel oil to make a bomb. Timothy McVeigh -- son of the working class, an army hero, the kid next door -- was about to become the worst mass-murderer in American history.
