Police that were there will make statements.
These may differ due to human error. Waist, shoulder etc.
That is why there are crime scene photographers and forensic people. So everyone goes by one thing at trial.

?? They were first at the scene - they commented the bible had been moved in the photos ?
The crime scene officers admitted moving the gun and her arm/hand ?
Not all of this evidence was given to the defence team .
So where is your argument going ?
what happened to the note?
And whos prints were in the blood on the bible - surely your books must tell you that?
