This is not a question of a "guest examiner", as you try to distort it. It is merely allowing a collegue to observe the autopsy.
I'm not trying to "distort" anything.
I am asking a question, "Is it common procedure to have guest examiners?"
If the answer is 'No' then this is a silly conspiracy thread.
If it's 'Yes', then I'll agree that suspicions should be raised.
