You didn't ask a question
I asked you to show evidence Sheila did not know how to chamber a rifle
However, fact remains that Sheila was NOT familiar with that rifle whether you wish to deny it or not.
On the contrary, The only person who could establish this as fact is Sheila herself. So its never going to happen
As for the crime scene pictures you say you have, unless you can prove it, your claim is no more credible than there being a picture of Sheila on the bed with one shot to the throat.
The absence of Hypostasis can been seen the photos already in the public domain.
If you don't find my claim credible it does not bother me, I don't have to justify myself to your satisfaction.
