That one should focus on obvious, high-yield activities instead of wasting time on less fruitful ones. Named after the notorious US criminal William Sutton (1901-80) who was charged with over a hundred bank
robberies and who, when asked
why he favored banks as his targets, is widely quoted to have said, "Because that's where the money
is." However, in his autobiography 'Where The Money Was: The Memoirs Of A Bank Robber' (published in 1976) he denies uttering those words and credits an unnamed reporter for them. Sutton, who was always well armed when attempting his heists, did say, "You cannot rob a bank on charm and personality" a statement
wiser bankers might disagree with.
Also called Sutton's Law.
