I think you are not looking at this from the viewpoint of the evidence at trial. It was a central part of the prosecution case that the silencer was fitted when Sheila was shot, based upon the fact that what was said to be almost certainly her blood was found inside the silencer. If that was the case Sheila cannot have shot herself as it would obviously be impossible for her to do that, then remove the silencer and put in in the box in the cupboard. If evidence had been available that the silencer was not fitted to the rifle when Sheila was shot it would have been clear that it was possible that Sheila did shoot herself. That does not prove that JB is innocent, but without that central plank the prosecution case is seriously weakened, to the extent that an appeal would succeeed.
Well yes, I understand that of course.
But the new tests, which are claiming to show that the silencer was not fitted when used to burn Nevill, doesn't automatically show that the silencer was not used during the shooting of Sheila.
In fact the blood evidence in the silencer, shows that it was used.
So if the conclusions drawn from the tests are accurate, and the blood in the silencer remains as previously accepted, then it just shows that the silencer was not attached when causing the burns, but it was attached when shooting Sheila.
It's a bit of a leap to say it wasn't attached at one stage, so it couldn't have been attached at any stage, despite the blood evidence indicating that it was.
That doesn't make sense to me.
