seth rich probably had nothing to do with wikileaks, but there's no doubt that he was murdered.
and honestly i can't hold it against assange for being on the lookout or even paranoid about things like that, given his circumstances. being wrong about that simply puts him in the company of a huge section of the political establishment that was promoting the case.
i also don't really care if the source of the leak was a Russian hacker. the damning part is the data was real.
Just to be more forceful on one point - Seth Rich had absolutely nothing to do with Wikileaks and it's extraordinarily shameful that Assange winked and nodded like he did.
Rich was a low level staffer working for the DNC to help voters find polling stations - he wouldn't have had any access to their email systems (and of course wouldn't have had access to Podesta's emails since Podesta didn't even work for the DNC and it was his private Gmail that was compromised).
