Why was it necessary to change the furniture?
They didn't change the furniture around, and I do not yet profess to know in which part of the house the two bodies were filmed as part of the training exercise video at the crime scene. You can clearly see that there are two bodies on the floor next to eachother. One of these bodies is Sheila, the other is June Bamber, Yet by the time PC Bird starts to take his photographs at 10 O'clock, Sheila's body has been moved to align with the edge of the bed in the main bedroom, and June Bamber is by that stage propped up against the main bedroom door. Lets put things into perspective, by the time police had stage managed Sheila's and Junes bodies at different parts of the same bedroom, and Sheila had been shot twice, June Bamber had already been shot between the eyes - but in the following photographic still taken from the crime scene video, the principal female has neither been shot between the eyes, nor alternatively been shot a second time in the neck...
A paradox which shows that Jeremy was not the killer...
