Elvis was traveling with some guns and his collection of police badges, and he decided that what he really wanted was a badge from the federal Bureau of Narcotics and Dangerous Drugs back in Washington. ...

All he wanted in return was a federal agent's badge. "I would love to meet you," he added. "I will be here for as long as it takes to get the credentials of a federal agent."
