That's because the theory does not stand up to scrutiny.
You have to argue that thousands of documents across Essex Police, The Forensic Science Service, Huntingdon Lab and The City of London Police are all backdated forgeries. Not only that but backdated forgeries that all happen to fit together and all the witnesses whent ahead with it. A conspiracy of this magnitute is not possible to sustain. People involved would sooner or later speak out.

The latest evidence to emerge in this case is the startling fact that the original exhibit labels for the Sound Moderator contained the wrong case reference number. This highlights the backdating of evidence by Police.
The first exhibit label shown on here is one fabricated by Essex Police to give a false ‘chain of evidence’ trail. Key to showing that this is a faked document is that its case number is SC/786/85 which DID NOT exist on 13th August 1985. This case number was not allocated to the investigation until after the 7th September 1985. From the 8th August 1985 to the 7th September 1985 this case was numbered SC/688/85. So if this exhibit label was a genuine original it would have the case number SC/688/85 on it and not SC/786/85. A Police Inspector said he produced this exhibit label on the 13th August 1985.
So why did the Police backdate evidence? Clearly they didn’t find this sound moderator at the scene because if they had it would have the original case number on it and not one that hadn’t even been assigned to the case at the time it was supposed to have been found.
This is quite simply a disgrace. Backdating evidence in this way is a serious offence. The CCRC have had this document for some considerable amount of time and still nothing has been done.

The evidence of the photographic specialist, Peter Sutherst, is supported by a large number of documents, which also prove that the scratches were made the following month, and not on the 7th August 1985.
