It's the Delaware Valley version of Willie Sutton, the infamous bank robber who told authorities that he robs banks "because that's where the money is."
In Upper Darby, Joseph Saunders, known as the Smiling Bandit in Philadelphia, told authorities he crossed county lines because, "I ran out of banks to rob in Philadelphia."
Note to Smiley: In Philadelphia, you didn't get caught even though cops had a clear picture of you mugging on surveillance cameras. When you crossed over the Upper Darby border, you were messing with the infamous Michael Chitwood Sr. and his territory. You learned the hard way.
