I really must try to wait until I read all the new posts ... but ...
1. I am not in the camp that proclaims Watson's innocence. Given the circumstances of Tina's death, only Watson really knows for sure and what he knows and what he says may be at odds. And, he is certainly biased. While I am not in the camp that proclaims his innocence, I am in the camp that proclaims that based on what I've seen through the media and SB, I find it hard to believe a prosecutor can get a conviction. That, of course, is a whole different thing.
2. In my experience, people become deluded by their own positions. They become so fixated that they manage to dismiss gaping holes in their positions. They tend to twist the facts to fit their theories rather than adjust their theories to address the facts. For example, once the police have a suspect, they look only for evidence with which to convict and ignore evidence that tends to acquit, and rarely look for other possible culprits. I cannot recall how many times I've seen a lawyer conclude a witness is lying and proclaim that everyone will see the lie, only to have the jury conclude the witness is credible and is telling the truth.

I think people involved are understandably influenced by the emotions of their connections to the case. Emotionally impacted people can be very eloquent and garner a lot of support by well intentioned people. The Judicial process needs to filter out the emotion and examine cold hard facts very hard when you are dealing with humans who filter and process information based on their personal interpretations!
