In view of such a serious complaint being made, the audio tape recordings we are speaking about would be the obvious evidence with which to refute such an allegation, so police would hardly seek or allow these to be destroyed, unless of course, there was some truth in what Jeremy had complained about...
The truth which must have been recorded on the audio tape from the eavesdrop, must have got some information concerning what bodies, or body was found, when the raid team first entered the kitchen - audio evidence which supports either the account given in the police logs, or the other version produced by way of police witness statements. In those circumstances, police would not destroy the evidence on the audio tapes obtained as a result of the eavesdrop. In particular, we have that message, timed at 07:38am, passed to Inspector Norman from the occupants of CA07 at the scene, who in turn are relaying messages passed at the scene by the raid team who have just entered the kitchen, messages which are being passed from the raid team in house, to the control room in a nearby outbuilding, which clearly refers to the discovery of one dead male, and one dead female found upon entry to the kitchen. At this stage, the raid team must have passed such a message from within the scene to the PS Adams who was located at the forward control point in a nearby outbuilding. The occupants of CA07 must have been privy to those messages, and as a result CA07 contacted the control room (Inspector Norman) to inform him that two dead bodies had been found, in particular, the body of one dead male, and one dead female. It must be clear to everyone by that stage, that there had been two bodies downstairs in the kitchen, and that several different people, some at the scene, others in the control room, and perhaps others elsewhere, that there was two bodies downstairs in the kitchen at the scene by 7.38am, at that time...
Furthermore...
Staff in the control room also had the benefit of the eavesdrop via the open telephone link through the kitchen telephone, with its handset off the hook...
It is recorded in one of the police logs, that at the time of entry into the premises, that five loud knocks could be heard, and the sound of voices. The audio recordings which existed covering this period was crucial in helping to determine (at a later stage) whether or not the account recorded in police logs regarding the discovery of two bodies in the kitchen upon entry by the raid team, or the other version of events as mentioned in the witness statements given later on by members of the raid team regarding the same entry. Added to this, is the fact that Jeremy Bamber upon being told by police at the scene that everyone inside the farmhouse was dead, accused police of shooting them all when armed officers went in...
