[Elvis] had a million badges and a blue police light in his car. He liked nothing more than putting that light on his car and pulling people over. He’d walk up to the window, show off his official badges and say, 'Son, you were speeding. Just wanna warn you to slow down.' The driver would look up, see who was talking to him and remain speechless. It he happened to see, for instance, two men fighting at some gas station, he'd drive right over there and stop the fight, just like that. His very presence stopped the fight.
