In summary Snow is saying Sheila put the silencer on.
Her blood got in it when she took the silencer off to put it away. This blood was from the injuries she got from fighting June.
Agree the silencer was used.
Agree it was Sheila's blood and there was no silencer fabrication.
Disagree that Sheila fought June and that PV lied about other injuries.
The prosecution case had to be that Sheila suffered absolutely no wounds that could have bled except the two bullet wounds to her neck.This was vital.If Sheila had absolutely no other cuts before she was shot then no blood could have got into the silencer,hence someone must have shot her then put the silencer back in the cupboard.
Therefore,absolutely no other cuts could be documented and any blood on her arm was put down to having come from Sheila's neck wounds.If there was any hint of Sheila having any other cuts at all,no matter how small,then the defence could have claimed that that was where the blood in the silencer came from.
So,ANY mention of wounds to Sheila appart from the two shots to the neck,no matter how small, had to become taboo.
THEN,and only then could the phenomena of backspatter be introduced without being challenged,it would be air tight.
Yet Bill and Roch have pointed out several small cuts as well as damage to Sheilas ear lobe,so is the backspatter claim as cast iron as we have been led to believe?
As for Vanezis,he may have been told it would be best to omit any mention of minor cuts to Sheila.
