The Oklahoma City Bombing
Documents obtained by private citizen through a Freedom of Information Act request show that the CIA and FBI had a spy satellite pointed over Oklahoma at the time of the Oklahoma City bombing. Why? Another FOIA request revealed that all four security camera tapes that recorded the blast site were wiped clean at 9:02am — the exact time of the blast. The FBI says the tapes were being changed at that time. This has given rise to much speculation in the conspiracy community that the FBI somehow knew of the attacks ahead of time, a charge the Bureau has always dismissed.
