It's really interesting reading everyone's views, as I'm only just catching up here!
I don't know if anyone agrees or not, but it often feels that one of the big problems with this case, is that any theory developed by anyone tends to mix in a big dose of personal interpretation with the facts. This even applies to people like Steve Thomas, Singular, Wecht, etc. Inevitably, some of their own personal beliefs and experiences get mixed in, simply because many of the facts still don't tell us conclusively who did it, how, or why? So we all end up wondering about the possibility of different scenarios (suppositions), that might explain the facts?
Sorry for the long, rambling post!
It is only natural to put personal feelings into it. As for Steve Thomas, Kolar, Wecht - these people either were personally involved with the investigation or personally reviewed case files, such as the autopsy reports and photos (in the case of Wecht). A personal spin on the case for these people is unavoidable. I'd expect it- they were on the INSIDE.
