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. More of this on Black Listed News
Various other analysts have suggested that the government was involved in a conspiracy behind the bombing, or that the government even planned the attack in order to justify persecuting right-wing organizations in a manner similar to Nazi prosecution of legislators after the Reichstag fire. Soon after the bombing an analysis by Brigadier General Benton K. Partin (Ret.) concluded that "the damage at the Murrah Federal Building is not the result of the truck bomb itself, but rather due to other factors such as locally placed charges within the building itself". Partin's report, released in the weeks following the bombing, was based on assumptions the bomb was fueled with diesel fuel, but did not account for the greater explosive strength of nitromethane in an improvised explosive device.
