I’ve believed Bill Binney from the first time I heard him tell his story and explain what happened, and I still do.
That does not preclude the possibility that some other party did “hack” the files independently. Both things could be true.
From nearly the beginning it was reported that the Clinton Campaign computer of Chief John Podesta was an easy phishing job, eventually suspected to be Russia, and John checked with the campaign’s IT guy, Barney Fife, and was cleared over the phone I believe to reply. Podesta did so and thus gave them the keys to the kingdom.
The DNC “Hack” was a leak suspected to be by Seth Richards and not a hack. FBI flopped their own duty by walking away from investigating anything, when told to run along and that the DNC contractor (Crowdstrike) would handle it.
Each party and all together then started blaming Russia, on the word of Clinton and the DNC. The FBI flagged in every media stooge around and parroted the Russians.
Thanks to Assange the whole world got chapter and verse on every word keyed, in those computers. And the Hillary server got shipped to a closet in Colorado! Go figure. Pathetic.
