The undercover cop: listen to ex-FBI agent Tom Zyckowski

 Updated:

Tom Zyckowski was one of four FBI agents who went undercover in parallel cigarette smuggling cases, Operation Royal Charm and Operation Smoking Dragon. The veteran special agent spent 25 years working for the FBI — 20 of them undercover — until he retired from the bureau in 2004. Posing as a Mafia “wise guy,” Zyckowski befriended an unlikely middle-aged couple — Charles and May Liu — who led the FBI through a dizzying world of counterfeit cigarettes and arms trafficking that spanned both U.S. coasts and reached as far as North Korea and China.
