No, maybe he's not an 'legal' idiot.
Does he know how to start a lawnmower, or change the oil? Does he know how to clean the gutters on a house? Does he know how to use the scanner at a market place? (hey, bodyguards, what's a debit card?)
My point being he taught at Chicago. BFD!
According to US News, Univ. of Chicago is the 6th ranked law school in the US.
