Tell me what you think of this theory. The destruction of the revolver (evidence) by the FBI and non-disclosure of the ammunition was intentional.
Someone or a group of people told them to purposely destroy the revolver during testing and not to disclose the other evidence in order to protect the turd.
Had this been anyone else, like the armorer, gross errors like this would have never happened. Even if it had been another defendant, I doubt the judge would have granted a dismissal. She would have tried the case anyway.
