So, this little matter of David Boutflour tampering with the silencer long before 'it' eventually got sent to the lab' (30th August 1985) to be examined by the ballistic expert (11th September 1985), also had him 'trying to unscrew the metal cap', to look inside it, but he claims he failed because the cap was screwed on too tightly, at least that is what he told COLP. If what David Boutflour claims he did to that silencer is true, it beggars belief that the lab' even accepted the silencer on either the 13th or the 30th August, and the 20th September, 1985, let alone examine it. Not only this, but there is one thing which no-one should overlook, and that is that because it is now on record that David Boutflour 'interfered' with the integrity of the silencer before it had been handed over to the cops, let alone being sent to the lab', and the fact that he told COLP that Essex cops knew he had done to the silencer what he had done, Why would David Boutflour be contacting the Essex cops on the 12th September 1985, to tell them that he had found the silencer to the gun, unless he had scraped the flake of blood from the silencer in his sisters possession that she had given to DC Oakey on the previous day? What I mean is, that David Boutflour can't have told Essex police that he had 'removed' a small flake of blood from the silencer before he had contacted them on the 12th September 1985, otherwise cops would have 'already known that he had found the silencer to the gun', beforehand (before, 12th September, 1985)?
