Ok, lets run through the finding of the silencer scenario, David Boutflour has already been in various rooms at the farmhouse where there had been bloodshed. He is now in the cupboard, fiddling around recovering bits and pieces, he finds the telescopic sights, and silencer for the rifle. Upon picking up the silencer and examing it, he does not see any blood upon it. He takes into the kitchen at whf and puts it on the kitchen table so that himself, his sister Ann Eaton, and his father Robert Boutflour can examine it. What becomes obvious by that stage is that there is no visible blood upin the silencer, otherwise when David showed the silencer to them at that time, he would have not said to them, 'look, I have found the silencer to the gun', he would have said something like, 'Look at this, look what I've just found tucked away in a box at the back of the cupboard in the downstairs office', he would have said, 'look, its got blood on it'...
His sister, and father, one or other, or perhaps both of them , would surely have taken a closer interest in the silencer at that stage, and upon seeing any blood upon it they would have tpld hom to leave the silencer on the kitchen table for the police to come and collect it from the scene. They would not have bungled a blood stained silencer into the boot of Ann Eatons car, along with Sheila's heavily bloodstained underwear, and driven all the way to the Eaton residency with the silencer, blood soaked panties and other loot they had plundered from the scene, being bounced and thrown this way, then that, up and down, left and right, without risk of contamination. Then upon arrival at the Eatons, the loot in the boot of the vehicle has to be carried out of the boot into the kitchen and the silencer placed on the kitchen table, where David looks at the silencer sgain, and he notices blood upon it for the first time. Blood which could only have got onto the silencer in the handling or transportation process. You would not I would suggest, upon seeing blood upon the silencer for the first time, start trying to physically attempting to unscrew the end cap of the silencer eith a view of looking inside. To have done this at that stage would be unthinkable, since if blood had genuinely been found on the silencer, it was for the police to deal with it, not the relatives...
