Two government agents were assigned the case of “Dread Pirate Roberts.” This “pirate” was the anonymous operator of “the Silk Road,” a website that sold illegal drugs by using the virtual currency Bitcoin. The agents caught their man, but not before becoming criminals themselves. They allegedly sold the information about their investigation and blackmailed the “pirate,” transferring big bucks to their own bank accounts. Their story demonstrates how thin the line is between good and evil.
