What the heck is on Sir John Fielding's head? Just as many blind people have worn sunglasses to signal their handicap, Fielding did so with a black band around his forehead. Fielding was blinded at the age of 19 in a navy accident but that didn't stop him from being a successful magistrate. Rumor had it Fielding knew the voices of 3,000 criminals. I remain a little skeptical of the last fact though!
