I think what Webster was trying to say in 2002 was that a forensic scientist would not be able to analyse a flake of less than 1/4 of an inch. So this was the size that Webster assumed it was, because according to Webster when reading Hayward's notes he does not write the size of the flake down.
I think the flake was found on the 5th baffle...maybe someone can confirm to us which baffle it was, please. :D
What Webster goes on to tell the court and this was very important. He asked Hayward whether precautions were taken to ensure that the different people carrying out the blood test were testing the same material? The reason for asking this is because if not it can give and erroneous result.
What Webster said was good practise is that the flake should have been dissolved and ground up to a powder thus, giving each individual that tested it equivalent material to work with. In this case it was not done therefore it could have been an erroneous reading.
***It was the Crown's case that the blood in the silencer was that of 3 people, like Caroline has pointed out, Sheila, June's and Nevill's. Now anyone with any sense can see this is impossible....What are the CHANCES of 3 drops of blood from 3 individuals caused by
drawback/backspatter landing in the same place on the same baffle?




It's also a fact that this is very unlikely that
drawback/backsppatter occurs from one person let alone 3.....More tests in this department and I am surprised that this has not been done....
