Undercover in a Colombian Drug Cartel

In the late 1980s, Robert Mazur was an undercover agent taking on the organisation of one of the world's most notorious criminals. Colombian drug lord, Pablo Escobar, was far and away the biggest trafficker of cocaine into the United States and US customs were desperate to bring him down. Robert Mazur came up with a plan to gain access to the cartel, masquerading as a money launderer. (Picture credit: BBC.)
