In light of David's posts, I will give further thought to the windows issue and where it fits into the scheme of things in terms of a legal prognosis now. I don't have time right now and I need to be careful in view of the bias of posters, which affects the information being given.
I have added a further evidence point above, (vi), in reference to it being thought that there was evidence that Nevill was involved in a physical struggle. However, I may yet move this into the 'Irrelevant' category, as I am not completely convinced that this remains a probative point against Jeremy. My line of thinking is that even if we accept that Nevill was involved in such a struggle, that can't rule out Sheila.
