As much as I would love Snowden to be able to move back, even if he could, how safe would he be? I know there are probably still a bunch of whack-a-doos that hate him. Four years ago when people including me were asking for trump to give him immunity and free ross on legacy media, there was a lot of hate comments about Snowden. I would love if he received immunity and could visit and travel again including meeting old friends and family, but I’d fear for him and his family to move back. 

 You are 100% correct on that. Even if he did get pardoned he can never travel nor reside in the US. Deep state would kill his ass deader than a hammer and it would be almost instantaneous.

Snowden knows it too. Still, a symbolic gesture of Grace would be appreciated.
