yes I agree about the silencer and if it is discredited then the trial was definitely a mis-carriage of justice - I believe that is the case anyway.
If JM admitted she lied? Again because the case was based partly on her evidence not proof - the above would apply.
Recordings of police conversations on the night? Would these exist?
The Ambulances who attended - wonder if the medics who attended were privy to any information?
Suicide note?( not the one in the bible ) forgot about that possibility ? If there was one and it was proved to be written by SC ? that would be proof. Could that be in the PII info? But if there was one I guess the police would have shown that to the relatives in the beginning to stop them in their tracks when they suggested JB had done it.
Another gun was also involved and there was forensic evidence on that gun?
The bible that disappeared - if that was SC palm print and her blood ? Would that prove that she or someone else had cleaned her hands?
Just thinking out loud really.
