First off,please don't tell me what I should do. Make a suggestion if you want, but you haven't earned the right to tell me what to do.
Second, respect is earned. Did it ever occur to you that you don't have all the pieces of the puzzle here. So to assume you do, and then judge how someone else should behave is both arrogant and ignorant. Even worse, it makes you a fanboi.
Lastly, all I said was that it didn't seem wise to let someone with a vested interest in the outcome be the only investigator. That's common sense, and honestly if i was Margo, I would have insisted on that transparency, if it were my company. That isn't a reflection on Michael, its simply protecting your interest and allowing the process to remain objective.
