Once you bring yourself to accept or suspect that photographs, 25, 26, 27, 28, 29, 30, 31 and 32, which are images of Sheila with two bullet entry wounds on her throat and the ansulz rifle atop her body, were taken after PC Bird took photo 23, not beforehand, and that police have tampered with and docotored photographic records so that they could mislead the court and everyone else into believing that such photo's were taken before 23, and that 7/8 photographic negatives which were taken showing views of Sheila's body before police shot her under the chin through mishandling of a loaded rifle, you can then also begin to see how totally unreliable the silencer evidence was and is? You can then see why the police and the relatives went to such great lengths to get the silencer/blood/paint evidence in?
If police shot Sheila with the anshulz rifle from the bedroom window at some stage after photo 23 was taken, they would have known if a silencer was fitted to the barrel of the gun when she was shot under the chin by them? Either, silencer was fitted to barrel, or not? Or, barrel of rifle had its metal end cap screwed on to it, or the external thread on the end of the barrel was exposed, when they shot Sheila - if there was no silencer used at this time, questions will need to be asked about how Sheila's blood managed to get inside a silencer in the first place? How could a silencer have been used to inflict the fatal wound under the chin, and the police not be aware of it, and for them to deny that they did not look for one, or find one at the scene?
