Just ignore PC Lay's witness statement of 1 October 1985, just ignore Julie's witness statement of 8 September 1985 and her trial testimony, just ignore Michael Fielder, Colin Caffell, James Richards: dismiss it all as lies, and have Jeremy Bamber telling the unvarnished truth..
I have not seen a witness statement from PC Lay, only a typed incident log. Perhaps you could link us to it or provide it, along with the statement of the person you referred to in the other thread who gave an account of Sheila? Let's be fair about this: you are claiming to have read these statements because you draw from them, so let us see them please.
What specifically did Julie Mugford's evidence actually prove? Just for the sake of argument, let's say that everything Julie Mugford said at trial was true. Does it prove that Jeremy was the killer? There isn't a transcript available currently, but as I understand it, the only confession she reported was false in that it was shown that Matthew MacDonald could not have carried out the shootings and this was accepted by the prosecution. Jeremy of course, variously, refuted and denied her evidence, but could that be because he had said those things as a joke or to sexually-excite Julie, or on account of some other similar flippancy, and Julie had misconstrued him? He therefore decided that he was left with no alternative but to lie, which if so was unwise, but that does not make him guilty. The question remains: What, if anything, did her evidence prove?
Turning to Michael Fielder, he did not give evidence. We could stop there, but I'll continue and say he was a proven liar. Not just in the sense that Julie was a liar, in that she was going through a phase in her life and was immature and had difficulties - something that can be understood - rather Mr Fielder was a mature man who lied and sensationalised things by trade, as a tabloid journalist. This is well proved. His word cannot be relied on and is worthless in any law-governed criminal trial. Indeed, his word on any subject, including the price of chips, is absolutely valueless. I would add, most sincerely, that I think he was a horrible man and I am glad he is dead - and I suspect lots and lots of people will join me in that sentiment.
As for Colin Caffell, a similar observation applies as with Julie Mugford. What does his evidence prove in regard to the shootings? Again, we don't have the transcript, but even if we accept everything he is thought to have said, it still leaves open the possibility that Sheila could have been the killer. That's not to say his evidence was worthless. Obviously the Crown have a right to a fair trial as well, and clearly Colin's evidence was of relevance because he knew her intimately - I have no dispute with that.
James Richards' evidence is next-to-worthless. Virtually every single person reading this has at one point held a lucid thought of hatred against their own parents, and very many people have said it. It's normal to hate your parents at times. You can't seriously propose that people should be sent to prison on such evidence? Oh wait, you do think that. That being the case, there's really nothing that anybody can say to you. You're just biased beyond all reason. You have no sense of fairness. You are unjust. It is to be hoped that you never serve on a jury.
