Straight out of the LN playbook. If a piece of "evidence" can't be authenticated, then make an appeal to a strawman of "vast conspirators" and hope that will distract everyone from noticing your unauthenticated evidence.
Then never actually explain how a jacket in a parking lot is evidence of murder in the first place...
Actually, it's straight out of the common sense playbook.
It's sad, but not surprising, that the Saint Oz fanbois don't see the significance of the jacket being found BEFORE their hero was arrested.
But you can bet your azz if his landlady reported he was not wearing a jacket when he left the boarding house, or if he was wearing or had a jacket with him when arrested in the theater, the fanbois would say that's exculpatory evidence.
And in this matter, the fanbois would be right. It would be exculpatory evidence. It would be hard to imagine Saint Oz wearing two jackets.
However, in the real world, the jacket was found before he was arrested and before his landlady reported he was wearing a jacket when he left his room.
So the cops got real lucky planting the jacket.
And they got 'hit the lottery' lucky when fibers in the jacket just happened to match the shirt Saint Oz was wearing.
TOO MUCH COMMON SENSE FOR THE SAINT OZ FANBOIS TO HANDLE
