WE MIGHT have had a faster response to Katrina, and prevented the 9/11 attacks altogether, if only we'd followed the advice of Dick the Butcher. Dick the Butcher is the character in Shakespeare's play Henry VI who says: "The first thing we do, let's kill all the lawyers." Dick is a repulsive character. Shakespeare's point is that lawyers are vital to the functioning of civilized society. They are the oil in the gears of commerce, the engine of democracy. But when we have too many lawyers, and we pay them too much deference, that oil can turn into sand.
