Only a fool like you would say what you said regarding the labelling of the gun silencer received from DS Jones at 9.15am, on the 13th August 1985, did not have a label at all attached to it, considering that in the statement in question Cook refers to it having been exhibit DRB/1, on that occasion. Ok then, prey tell what exhibit reference it did have attached to it on that occasion, where in Cooks signed witness statement dated the 23rd September 1985, does it give any other exhibit reference? Where in the statement does it say that it did not have a label attached to it at that time? Where does it explain how the gun silencer in question ended up bearing the exhibit label DRB/1 on the 13th August 1985, considering that the only other references contained in official police and lab' documents, state that silencers in police and then subsequently in lab' possession were labelled, SBJ/1 (13th August 1985), DB/1 (30th August 1985, and DRB/1 (11th September 1985)? How can Cook justify naming the gun silencer given to him by DS Jones at 9.15am, on the 13th August 1985, was exhibit DRB/1, when according to other evidence elsewhere, Cook only had a silencer marked SBJ/1, and DB/1 up until the 30th August 1985. How can Cook or anybody else justify allowing Cook to think he can get away with deliberately manipulating the exhibit reference procedure where ever and whenever it suits him...
The exhibit number was assigned by Cook that was his job not the job of Jones. He gave it the exhibit number, he stuck the sticker on it and then he filled out the Holab forms. It wasn't supposed to have a sticker on it when Jones gave it to him and it didn't. He took care of it.
COLP determined that after all items found by Boutflour were in police custody that they would change the prefix assigned oso that all these items reflected they were found by Boutflour. So a new sticker was placed on it and all references were changed to reflect the new designation DB. Because DB was used by David Bird they were changed again to include Boutflour's middle initial so changed to DRB.
You have nothing at all to refute the findings of COLP you just make up things to pretend something else happened because you have no valid way to attack the moderator. If you had a valid way to undermine it you would not waste your time with claims disproved back in 1991.
