The FBI's undercover program is the focus of the next two episodes of FBI Confidential, as host Sheryl Worsley learns how, when and why agents pretend to be someone they're not.
In part one, we talk to Supervisory Special Agent Katrina Amos, who oversees the undercover program for the FBI Salt Lake City Division. She explains the training process and what has to happen behind the scenes before an agent goes undercover, from cases like Agent Joe Pistone's six-year-long "Donnie Brasco" operation, to those that are a lot shorter and less complex.
Next time, hear from a recently retired agent who spent 22 years doing various undercover cases -- including getting tattoos to play his part and avoid discovery.
