Samson, you obviously have little, if any, understanding of those with a narcissistic personality intent on getting their hands on their family's wealth. Bamber's own defence team were advised that the memory of the terrible nature of what he'd done had been shoved to the back of his mind, then dropped off as if it never existed. Bamber and Bain... two peas out of the same pod imo.
Why is it that you constantly avoid all the other evidence and focus on only one particular part of the case, i.e. the "suicide" shot which is open to different interpretations, not just yours? There was nothing to stop David Bain sneaking out from behind the bay window and firing at close range whilst his father was engrossed in prayer with eyes shut and oblivious to anyone being present. Some killers just get lucky. Then we have the ejected bullet casing position nowhere near where it should have landed, and that mysterious self-balancing magazine case.
I thought "Black Hands" was a thorough expose of David Bain's involvement... well done, Martin van Beynen.
