Okc bombing had an unexploded bomb behind a locked key card access door controlled by the FBI. They intended to completely destroy the building. The second or third person was never found and the FBI refused to look for them (FBI won't look for FBI). Total of three bombs. Only one went off. The first attackers on the twin towers in the garage was trained, funded, equipped, and driven to the area by FBI. Their official position is that it was an accident they gave him real explosives. They provided the van too. The FBI and CIA are the world's largest terrorist organizations.
