I think he's a genuinely low IQ individual who is passionate about digging around where he shouldn't dig, and trying to make sense of things. He flew too close to the sun by actually doing some decent investigative journalism and getting due praise when he was way younger and less of a deranged alcoholic. And that success got to his tiny brain, and then alcohol and drugs... And now he's a deranged lunatic who... Basically wants to spread lies about people whose children were murdered. And he's so lost in this "truth seeker" identity that has so clearly deteriorated to insanity, that he's not only willing to, but he is ultimately going to die on this hill.
Not saying he hasn't earned that, but I guess I'm saying I'd still be interested to know the results of a lengthy psychiatric eval on him.
