I watched the movie “The Infiltrator” (2016 film) last weekend.
Robert Mazur (played by Bryan Cranston), An American DEA(Drug Enforcement Administration) undercover agent investigates the organization of a Colombian drug lord Pablo Escobar’s cartel.
During the investigation, he earns the trust of the executives, and finds important evidence deep within the cartel. Meanwhile, as a result of earning their trust, Robert has a conflict of interests in dealing with him as a mere investigation target or a friend.
I think an undercover agent is playing a role playing game in real life. It might be exciting, but I don’t want to play such a game because it’s too risky.
