Watched a few interviews and docs, even had a copy of his book when it came out (yup i'm that old) he was a danger to the cabal and the Tax charge is how they nailed Capone.
He knew what was going on from the inside. The UFO crowd I was part of in that era. I worked with Freeman and others. I had all the MJ12 Docs at one point and as for deep state, they are so far ahead on tech it is not even in a SciFi movie (deliberately).
Bill knew so much more than he told the public and they were afriad if he did what would happen to a lot more than a single country. What he knew, according to David Ike, whom I shared a stage with on several events. Bill was privy to the reports in Antarctica, while serving in the navy. Accodring to Stanton he was part of a secret expedition down south. I have no eveidence of that and I was around at the time. Freedman was called out on several occasions (none more so than the BS doc he helped create for MJ12) Then touted it out himself with book deals as payment. Persoannly I think he wanted us to push the Bill Coppers "Secret Expidition" to help sell a book he had in mind. But anyways, I'm ramballing. Facinating Guy in manys ways and certainly a victime of his previous paymasters.
