A clear picture has emerged concerning three main areas of the aga surround where scratch marks have been found at one time or another. These areas can be identified as follows:-
(1) Underneath mantle shelf
(2) Upper front right hand face of aga
(3) Left hand side face of aga
Marks made at (2) and (3) were not present on the morning of the shootings, but were deliberately made there when someone deliberately scratched the end of a silencer against it...
It must follow, therefore, that the only marks which could have been present at the time of the shootings, were those underneath the mantelpiece. This being the case, one is then left to contemplate what DS Davidson told COLP in his 1990 interviews, about the reason why a paint sample, RC/1, was taken from underneath the aga by DI Cook (SOC), on 8th August - because some similar red paint had been found to be present on the end of a guns barrel...
When asked by COLP whether he was referring to paint found on the end of the silencer, Davidson responded by saying, "No”, some paint had been found on the end of a guns barrel, a gun which had been found downstairs, not upstairs...
It must follow then, by a reliance on the power of deduction, that a silencer did not make the marks underneath the aga mantelpiece, but that the end of a guns barrel did...
Moreover, the gun in question was one which was found downstairs at the scene, not upstairs...
It must also follow, based on logic, that the marks on these other two areas of the aga, (2) and (3), were made by a silencer striking the aga, on an occasion long after the shootings, and that this leads to the inevitable conclusion that there was no silencer fitted to the barrel of the gun which struck the aga, during a purported struggle involving Ralph and his killer, which is contrary to what the prosecution alleged during the trial...
It is possible to reconstruct when one or more of the prosecutions witnesses deliberately contaminated the end of the silencer, so that it could allow the court to be deceived into accepting that a silencer was used in these shootings, which produced other advantages to the prosecution case, but which was grossly unfair to the defendant...
