If you believe the 1 killer theory, I absolutely agree. Red herring.Total red herring. To much time and brainpower wasted on this guy. He makes for good television, and that is why he was on the show. He is not the killer so why even think about it?
If you believe there are more than 1 killer, its tough at the moment to rule him out as a POI.
I'd be interested to see a real psychology expert to read into his posts and evaluate the contents.
