"Banducci made it pretty clear that he wasn't going to answer the question" Banducci , should have prefaced his answers[see transcript above with the words , "I have no idea what the ROE is , as it is a meaningless figure that doesn't relate to profit.''.] Coles , forewarned , basically said that.
As McKim already knew the answer , why the need to ask the question? Let us assume he isn't dumb, then the only reason I can think of is for political theatre . A misuse of the powers of the committee , which brings the system into disrepute. Selfish , self- righteous tool.
