It is just as inconceivable that the family were able to fool the police with this ploy at such an early stage of the enquiry. If they were that far ahead of the game why were they using PC Carr to inform them as to what was happening and why were they pestering Taff at every opportunity. Further why did the police forge DB's witness statement to change DB1 from a silencer to a soil sample. See my post. This ploy would not have worked while Taff was in charge. It could have been conceived early but only executed once Ainsley was in charge.
It was not the polices job to scrutinise and pass judgement on forensic evidence. Its their Job to secure the scene, collect and pass on any forensic evidence to the forensic staff at the lab.
We don't know what the police involved personally think of the silencer. With the exception of Stan Jones and Miller as they have made their views known to us on TV shows.
Stan Jones and Miller both express the view the silencer is genuine. Stan Jones comes across as a right cretin so that answers why he thinks its genuine. Miller on the other hand expresses the view that the silencer is genuine because the lab told him so.
As far as the lab is concerned, we know that they did not understand the dubious circumstances the silencer was found in, since DI Cook handed it to them under the assumption that Stan Jones had found it and thus the staff had a false pretence. We know from Mark Webster that Hayward had never seen backspatter in a silencer before. We know from Fletcher's testimony that he does not understand the subject of backspatter very well. And neither has he seen backspatter in a silencer before either. Thus the lab fooled themselves. Millers belief is based purely on circular reasoning.
There probably are members of EP that think what I think. But they wont dare express that in public would they?
