The same thing happened after the Oklahoma City Bombings in 1995. At first local authorities said that TWO undetonated explosive devices were found (Windows Media video), but later the feds claimed that there were NO bombs in the building. According to the government, a Ryder rental truck with a fertilizer bomb caused all the damage. They LIED through their teeth. It was admitted before the feds tampered with the evidence that C4 charges were planted in the building. One detonated, but the other two failed to go off. The Ryder truck DID blow up, but it was only a cover attack for the bombs in the building. All of the outside security cameras were confiscated by the FBI and erased!!! Talk about a massive cover-up!
