There are SOME things which they should have all remembered like who was actually there when it was found. David Boutflour recalls the event as though he were alone, Robert Boutflour puts himself at the heart of things and Ann - well, she remembers it but didn't think much of it at the time. Basil Cock has never mentioned it and only recently, Barbara Wilson has joined the 'I saw the silencer covered in blood' club - so I'd say she has pretty much changed her story quite significantly.
The strange thing about the silencer is that although it was found on 10th Aug, no one makes a statement until AFTER Jeremy becomes a suspect? I'm sure you are familiar with the Cognitive interview where a speedy interview with a witness is of the essence! Also Ann describes the blood on the outside of the silencer as a 'sticky blob'. I don't think I need explain that after 3 days, the blood wouldn't be sticky and said blob would have dried and detached itself. We did an experiment to test the blob theory, the blood changed colour and dried within an hour and peeled away from the surface of the metal torch which I used, and crumbled. The blob was never mentioned in tests, even though it had survived (according to the relatives) for 3 days in a cupboard, in transit, in storage at Oak farm and in further transit to the police station inside a cardboard tube. It's just that little trip to the lab that it would seem the blob gave up the ghost and suddenly disappeared. Funny that!
Blood doesn't just dry and peel away instantly from all metals. It did not fall off the baffles it stayed there until scraped away. It doesn't dry and just fall out of barrels of weapons it has to be scrubbed off. Your supposed test doens't prove anything.
The blood on the outside was not successfully tested that is why it wasn't mentioned, it doesn't prove anything. Some of the blood found by the prosecution on the baffles wasn't either so again no results mentioned for that blood. Blood that wa ssuccessfully tested wa smentioned and whose blood was it? Sheila's blood type.
Whose bloodtype did the defense find? Sheila's and the microscopic blood found by the defense was found in September, so much for all blood falling off after 3 days...
There is no accidental contamination theory which could even theoretically account for accidental blood transfer that would result in the blood tested by the prosecution and defense.
The ONLY theoretical theory of how the blood could have intentionally been planted woudl be to use a device to spray blood inside. Are there any devices in existence at the time to have been used? The defense was unable to find anyone to discuss such a device let alone any evidence th epolice or family had such a device. There are a whole lot of logistical hurdles including needing to recongize in the first place you should spray the blood inside not just pour it in or use a dropper.
If they didn't spray it in them the blood distribution would have been different and someone for the defense either at trial or on appeal would then say hey this is not right this distribution is indicative of being planted not back spatter. But only someone with a great deal of skill would be aware of this. Again I'm the first person to bring it up to the arm chair detectives in this case so obviously it is not common knowledge.
What is so surprising about police taking notes when they talk to peopel and only getting a statement when it is absilutely necessary? That is standard fare. Why would they bother having people give signed statements when they don't know if there will be a need for one or what such statment should entail?
Lawyers do the same things we take notes when we interview peopel inforally and only have affidavits signed when we need them for a set purpose or depose people when needed for a set purpose.
