The reason why no police officer says that he or she saw a particular room light being switched on and off, or that a light which was not on, being switched on was because for that to be said by anybody, or written about by anybody, would have resulted in the prosecution being unable to prosecute Jeremy Bamber for the five murders on the footing that he had shot and killed everyone, and staged the scene with one of the guns in his sister's possession, because the lights in the rooms of the farmhouse could not have switched themselves off and on, or as the case may be, on and then off.
It is just as important to note, that there does not exist one statement by any of the two dozen or so police officers who were present at the farmhouse throughout the entire incident that none of the rooms lights were not always off or on, or on or off continuosly...
It seems somewhat obvious to me, that the lighting arrangements inside the farmhouse in every room both downstairs, and upstairs would or should have been a major consideration. In that respect, the police would ordinarily have created a log identifying each window and door on all four sides of the house, on the ground floor and first floor respectively.
So, where is the part of this lighting register?
Withheld?
Destroyed?
Or, are parts of its truth incorporated into witness statements in such a way that no one single person actually says they saw any light in any part of the farmhouse being switched off and on, or on and being switched off, even though lights were being switched off or turned on, or vice versa? It was an operational decision to deal with this issue so as to not Provide Jeremy Bamber with an alibi...
It seems to me that the police at the scene were aware of and that they did see various lights being switched on and off in the farmhouse..
