First of all, everyone should remember the sighting of the silhotted figure seen by PC Myalls, PS Bews, and Jeremy Bamber, standing and moving about in front of the main bedroom window! Forget the nonsense spouted by PS Bews about it being a trick of light, because he knows it was a living person they all saw, and had to have been either Neville Bamber, June Bamber, or Sheila Caffell! Bews knew full well by the time he came to testify during the October 1986 Chelmsford Crown Court trial, that if he acknowledged the presence of a living person inside the farmhouse (i.e. a person at the main bedroom window) with Jeremy outside in the grounds with himself and PC Myalls, that the case being pursued against Jeremy Bamber would have collapsed there and then! That's why Bews dishonestly claimed it was a trick of light! Notice, how PC Myalls did not make the same claim, and he was there outside alongside Bews and Jeremy! Instead, PC Myalls describes the sighting of this person as an unidentified male, as per the very first entry in a police record entitled 'THE MAJOR INCIDENT PROJECT'..
The following therefore needs to be taken into account..
If the silhotted figure that was seen at and beyond the main bedroom window was Sheila Caffell, it means that Jeremy did not shoot her dead, either downstairs in the kitchen alongside the body of Neville Bamber, and that he could not and did not shoot his sister dead upstairs in the main bedroom, nor stage her death scene there on the main bedroom floor to promote the idea that she had committed suicide! Secondly, if the silhotted figure was or had been June Bamber, then Jeremy could not be held accountable for shooting June dead between the eyes, or for staging her death scene either on top of the bed, or by somehow moving her body against the door to the main bedroom! Thirdly, if the silhotted figure was or had been Neville Bamber, then Jeremy could not have been involved in a struggle which led to his death downstairs in the kitchen - such a struggle would have to have occurred after the sighting of the figure at and beyond the main bedroom window! Neville was killed off during this struggle, so it goes without question that if the silhoetted figure had been Neville Bamber that Jeremy can't have struggled with him, beat him, over powered him and killed him off in the kitchen later!
PS Bews did not shit in his trousers and dash back to the police patrol car that was being manned by PS Saxby and pass a situation report requesting that firearms to be deployed to the scene immediately because of a trick of light at the main bedroom window! He told the control room that they (himself, Myall and Jeremy Bamber) had just witnessed somebody standing, and moving about suspiciously inside the main bedroom window, who could possibly have been armed with a gun!
