Since David Boutflour did not contact Essex police about the find of the silencer (DRB/1) in the cupboard at the scene on 10th August 1985, until 11th September 1985, it beggars belief that the two sound moderators sent to the lab' prior to the 11th September 1985, namely, SBJ/1 (lab' item number 22), sent to the lab' on 13th August 1985, and DB/1 (lab' item number 23), sent to the lab' on 30th August 1985, could be the same silencer he was referring to, in his call to the police on the 11th September 1985 - how can a silencer (DRB/1) which David Boutflour did not report to Essex police until 11th September 1985, be sent to the lab' on 13th August 1985 (SBJ/1 - lab' item number 22), and 30th August 1985 (DB/1 - lab' item number 23), to be examined by experts, Howard and Fletcher, on those occasiones, I am sorry but if this is what happened, I cannot accept that any evidence obtained from the examination of a silencer, on or after each of those occasions (13th and 30th August 1985) can seriously be treated as legitimate evidence, since the integrity of the silencer, sent to the lab' on those occasions (before 11th September 1985) is well and truly compromised...
