Sorry, but you come across as rude and obnoxious with that statement.
Sorry JSF, but you may also be guilty in that respect. PE's response to CM seemed reasonable. You may not like what he is asking, but that does not make him rude and obnoxious. I would suggest that it also does not make him unprofessional.
I have mentioned it before, but there is still a real feeling of people closing ranks here and refusing to contemplate or ask the difficult questions. I don't hold by the "wait for the investigation" view. Constructive discussion can be of enormous benefit in the meantime.
