A video that shows Oklahoma City bomber Timothy McVeigh at a U.S. military base that specializes in explosives and demolition training over a year after he supposedly left the army puts the official story of the April 19 1995 federal building bombing under serious doubt and mandates a re-opening of an investigation into the terror attack that killed 168 people.

The video was released by Bill Bean, a film producer who has suffered intense surveillance and harassment since taking the footage, and is the subject of a February 2007 Hustler Magazine feature story.
