Her bedroom door may have been shut = No noise.
A silencer was used = No noise.
The twins did not wake = No noise.
June was shot & died in/by the bed = No noise.
Neville & Jeremy went downstairs = Minimal short term noise.
There was a brief but brutal fight = Noise in another part of WHF.
This whole process may have taken less than five minutes. Most of which was noise free = Not enough long term loudness to wake Sheila. Who may have been in a deep sleep. And under sedation.
Adam these are questions that anyone can have their own opinion on. Unfortunately no one is in full possession of the facts. That is why in my own opinion, for what it's worth scenarios can take many forms and conform to the facts as we ourselves see them, but because no one is in full possession of the facts they are what they are, our own concept of what happened.
That is why it is relatively easy to make up different scenarios, some for and some against Jeremy. If we were in full possession of the facts there can only be one interpretation. It has nothing to do with bias, well it does up to a point. But just because someone agrees or disagrees with a certain scenario that does not necessarily mean that they are biased and that is why they do not agree with one or the other?
That is why the audio tapes of the raid team going into WHF would be very useful. Why? Because then that will give us a more complete picture of what was actually heard as they went in. Not only that, but we would hear the actual words of the officers as they went into and through the house. But unfortunately Essex Police have said a catagorical NO to that request.
