In addition, there are documents on MF from a Bonanno informant that someone (maybe Ed) figured out were from Bill. This informant began giving info when his blood family lost standing in the organization, and later he stopped providing info when the war settled down. The contact agent for the CI was an agent that Bill Bonanno was known to have been friendly with during that period.
I'm not sure that this informant I originally posted about in this topic was Bill, only that Bill was an informant and his last book's intro on mafia origins matches this informant's description of mafia origins 40+ years later. It's not just that it's the same basic story -- it emphasizes the same exact points in a way I've never seen from another source.
Side note, but Magaddino claims Joe Bonanno himself was "too close" to law enforcement. He talks about Bonanno going out drinking with cops somewhere (maybe upstate, where JB had farm property). On one of the Magaddino transcripts, he cites this as a reason why Joe Bonanno wasn't told about the Apalachin meeting. Doesn't JB say that he wasn't invited in his book as well or am I misremembering? Not saying he was an informant, only that he may have been a little bit loose long before he decided to publish his memoir.
