I know Cyril here in the 'Burgh. He is nothing like Joe Biden. Cyril is bald and Biden has plugs.

Seriously, Cyril likes to hear himself talk, but he has a lot to say.
Your rough assessment of him is not correct.
Also, you wrote, "He was not asked, he asked himself." Who suggested that he was asked?
Bring up Wecht at a meeting of pathologists and you can get an idea of how he is regarded professionally.
The ME serves the state, justice. He does not serve the families. He is independent and professional. This one appears to be from what I have read of him. He does not need to have anyone there for "fairness". All his work will be available for anyone else who wants to give an opinion.
All this demanding observors is some lawyer's idea. Brings to mind Johnny Cochran demanding observors at the DNA labs. It is a distraction.
