It might help if Vic was able to provide the professional source re the pre trial view. I think it's come from the Wilkes book. It might help if we could get the context for Daynes' comments. I wasn't trying to trash her professional standing, she is a chartered forensic psychologist who has never examined Bamber. I'm not sure what you mean by whether it matters or not.
By 'whether it matters or not', I mean that it's not definitive, Jeremy isn't required to be a psychopath in order to be guilty, and likewise he could be innocent yet still be a psychopath.
It's just background and propping up arguments, I guess in a similar way to the argument that he's never been violent before, which doesn't actually matter in terms of whether he carried out the crime or not. He doesn't have to adhere to any particular profile (although I'm not saying that he doesn't).
I don't think I've explained that very well?
EDIT: 'Not' inserted into phrase in brackets.
