You refuse to believe it because it severely harms your claims of Jeremy being innocent.
The evidence proves beyond question that Nevill was beaten as he tried to fight off the killer. This proves the gun was not loaded because the killer would simply have shot him instead of beaten him. The only reason to beat him is because he was a threat if he had passed out he would not have needed to be beaten. He was beaten unconscious because only with Nevill unconscious could the killer safely reload the weapon.
There is no question Nevill blocked more than a dozen blows with his arm and was bashed int he face and then was bashed several times in the skull so hard that his skull was cracked and he was rendered unconscious. There is no question that in the process: the lampshade was broken, crockery broken, the mantle was damaged, the butt of the weapon broke and the weapon and killer were splashed with Nevill's blood.
You ignore the irrefutable evidence this happened because it reveals Sheila was not the killer. If Sheila had been the killer then her hands, nails and feet would have had some sort of damage and she would have had Nevill's backspatter on her.
I refuse to believe there was any "violent struggle" in the kitchen based on the pathological evidence. Dr Vanezis uses the words "spirited defence". This is not the same as a "violent struggle". NB was too badly injured from the shots he sustained upstairs to enter into a "violent struggle" with anyone regardless of gender and size.
The "violent struggle" seems to stem from the raid team based on knocked over stools, chairs, crockery and a broken lampshade. You said in a previous post a while back NB was probably bouncing off the walls due to the gunshot wounds he sustained. Therefore it follows he most likely stumbled into the furniture since he had to pass it from the hall to where he was found in the kitchen. Regardless the kitchen furniture looks flimsy and cheap and would easily be moved. Anyone swinging a rifle around is likely to catch items in its radial.
If you want to rule out SC based on her hands, nails and feet then what about the other victims that walked about in blood, sugar and broken glass/crockery? Why didn't Dr Craig, a police surgeon with 30 years experience at the time of WHF case, observe and note this? Also Chief Sup George Harris who observed all victims in situ with Dr Craig?
The pathologist, Dr Vanezis, did not observe the victims in situ but was experienced and trained to observe and note such. Four police officers that attend soc and observed victims in situ attended PM to assist Dr Vanezis. He was also aided by soc photos.
