Most police departments have people who work undercover. Often that means little more than coming to work in civilian clothes. Not in Memphis. There's a well-known school there that trains officers to go deep undercover. Many graduates go on to work for the Memphis Police Department. The officers take on a completely new identity and go undercover for months or years gathering intelligence on drug dealers and other criminals. Detective April Leatherwood went undercover as a drug addict for nearly a year. April says she severed all ties with family. She was so deeply undercover as "Summer Smith," she began to question her real identity. April talks with Dick Gordon about the high price of catching the bad guys.
