Bill Cooper is a very strange individual.
Much of what he said was true, and yet there can be no doubt that his "Silent Weapons for Quiet Wars" which he said had been "found in a photocopier" was a pathetic forgery, looked like it was written by a teenager, or something similar with little basic understanding of how humans operate. Kind of like someone who thought you could use cellphones from airplanes on 9/11.
Fake, but accurate? Just like with UFOs. He said he saw them, then said he didn't. He's also an L.A. guy, not many people know that. He also had Jordan Maxwell on his show who claimed many times to be an alien. He also had Anthony Hilder on his show, and dedicated at least 2 other shows to him. Hilder is another very strange guy, who is implicated in the RFK assassination, and it mentioned in a book on the subject.
So yeah. There's a lot of anons who mumble the name Bill Cooper, as if it's holy, but there's a lot of very weird shit around that dude.
Also if you listen to his last show he clearly knew it was his last show.
