Pretty much every doctor in America can tell you about Willie Sutton, which is surprising because Sutton was neither a medical researcher nor a victim of a famous accident or disease. No, Willie Sutton was a bank robber who stole almost $2 million over four decades and escaped from prison three times. And doctors know him for an apocryphal quote. Asked why he robbed banks, he supposedly said, “Because that’s where the money is.” Despite later denying that he ever said that, he did write in his autobiography that he would have said it. Doctors have repurposed this as something they call Sutton’s law, and it guides them in their diagnoses: Go where the money is.
