That's a very optimistic view of the US justice system's treatment of whistleblowers (surely they would contend that all of their programs were legal), but now his being granted asylum by Russia isn't evidence but a new incongruous fact we need to explain since the hypothesis is now apparently that he is a Chinese turncoat. So I don't see how this helps the case.

I once publicly stated here that I think some accounts are astroturfers, and I think some are deep state too. I am not making specific accusations.
