Fuck dude, I'm not about to watch an hour long video, haha.
I mean, ya, I have NO idea how he's being treated. Do you? I mean, I feel he hasn't made any public addresses since that very first interview (maybe one more after that). No, I haven't researched this, maybe I will. Just sayin, that I believe the original plans were to get him to Venezuela, which I'm sure the Russians being Russians, would have NO problems accomplishing that.
Maybe the Russians are treating him well, but they don't have to treat him well to get documents. You can cut off a man's finger for that. And NOT saying they are, haha, but we don't really know.
I would guess, that they would have no reason to treat him poorly UNLESS they wanted information that he refused to give.
