to establish a wrongfull conviction you dont need to know who fabricated the evdence just that it was fabricated.
Eh ? What are you talking about ?
There is no evidence the scratch marks were made after the crime.
From reading you're posts I suspect you still want to believe the relatives fabricated the silencer.
Therefore you need to prove they were able to do this by answering my 15 questions. Not bottle it and hide behind this weak thread question.
