We have avid Bernie Sanders supporter Seth Rich, who watched the DNC sabotage his candidate and fatally decides to hand a memory stick of email data to Wikileaks (corroborated by Kim Dotcom and pretty much by Assange too).
Then there's a Podesta email saying they're going to make an example of leakers and shortly after Seth gets whacked (not a robbery as nothing was stolen).
So we have clear Means, Motive and Opportunity for Seth Rich, together with his death - a hallmark of people around the Clintons - the body count is around 115 so far IIRC.
On the other side we have Mueller and his FBI (who has never inspected the DNC server - they only let their private contractor 'Crowdstrike' near that, and it's Crowdstrike who told everyone it was the Russians).
So the FBI has zero evidence it was a Russian hacker. The NSA has no evidence. Neither does the CIA. Or the State department. Or the DOD.
So yes, obviously we need to finger 6 Russians for it, it all makes perfect sense. CNN told us it was the Russians, so it MUST be true.
