You sound eager to convince us he’s guilty.
No, I just think that this guy has no credibility and it is embarrassing to see people hanging on him for advice and recommendation. His company dumped him, he admitted killing the guy in Belize, he is a drugged out looney. Why trot him out to say Russians were or were not involved. Seems like there are lots of other sources, more credible. If not, is this really all we’ve got to back up the claim that the Russians were not involved?
