I got a real kick out of this.
Coleman and other agents began to work deductively, backward. "We had always wondered why his guys, when we caught them, would always go to trial and risk lots of jail time, even when they would have saved themselves a lot of time if they'd just plead guilty," he says. "What we realized when we saw those binders was that they were doing a job. Their job was to stay on trial and have their lawyers use discovery to get all the information on DEA operations they could. Then they'd send copies back to Medellín, and Escobar would put it all together and figure out who we had tracking him."
Apparently, drug dealers aren't stupid. Pablo Escobar had hired people to go to trial and get as much information about the DEA as possible.
Anyway, read the whole thing, it is a great overview of American drug policy.
