Absolutely they can skew. But it really does a thorough job making its points, and there are so many people in this pointing out the numerous shoddy, sometimes downright incompetent police work. And the reasons the public was so confused are so common: an investigator who was a genius in his own mind has made his mind up, a journalist was all too willing to print police leaks by this guy to feed the media frenzy, and a lazy national media lapped it up in all its sensationalism. Meanwhile, the boring and old Denver detective, who was doing the boring work of actually getting the little facts right in order to eliminate theories, was getting closer to the truth than anyone. And it doesn’t seem he has a tie to this doc, nor is he interviewed (though I’m not completely done with it).
I think you are talking about the same investigator. Older guy at the time, with a reputation of solving hard cases?
