I think at the time of the OKC bombing, they were trying to hide a successful attack on our land. One can also wonder about the rash of Airplane crashes back in the 70’s/80’s, because those were almost eliminated with upgraded security measures.
PBS put out a video a few years ago about the “Man who Knew”, a few years ago, who was an FBI agent who was a thorn in the side of the FBI, because he was so obsessed with Bin Laden and an attack he knew was coming. Eventually he left the FBI and became head of security at the WTC. His first day at his new job was the day the towers came down.
You just can’t put anything past tptb anymore.
