I dunno, over to you ...
Well, I believe a strong enough case has already been made out for Bamber being innocent (and framed for these murders by the police / relatives) if the rifle which WPC Jeapes saw to be leaning up against the main bedroom window, since as I have already indicated and pointed out, if the rifle in question was the one which was later planted onto Sheila's body when the police moved her body from the bed to the bedroom floor, Jeremy could not have killed Sheila and stage managed her body with the rifle atop her body on the floor to try to make it look like Sheila had taken her own life, after killing the others. If the rifle in question was leaning up against the main bedroom window before the raid team set foot into the house, do you not, or would you not tend to agree that Jeremy could not have stage managed Sheila's body on the bedroom floor, as alleged, and that the police must be and are responsible for doing that which they have allowed Jeremy to take the wrap for?
Yes, or no?
You see, if you are correct and the rifle in question was actually leaning up against the box window, it either serves to identify an additional rifle that was found at the scene, which for one reason or another police and the DPP do not want anyone to find out about, or as the case may be, it was the very rifle which later ended up atop Sheila's body when PC Bird started to take photographs showing Sheila's body on the bedroom floor with that rifle atop her body - now which way do you want to play it? Was it an additional rifle, or the same one which was used by police to stage manage Sheila's body in the bedroom?
Imagine, for one moment, if it was the actual rifle which was later photographed atop Sheila's body, imagine what this evidence would mean? In many ways it would be just as powerful as if the rifle in question had been leaning up again st the main bedroom window, before police got into the premises, and if true then somebody had to take hold or control of it and either use it, or plant it atop Sheila's stage managed body after police entered the premises at about 7:30am...
Do you not agree?
