The 1980s was the wild west of drug trials. And there was no bigger cocaine cowboy than Carlos Lehder, who co-founded the Medellin Cartel. Lehder turned to Edward Shohat to represent him in a 7-month trial in which the prosecutor, nicknamed Mad Dog, called 29 snitches. In this episode, the finale of Season 4, David Oscar Markus takes Ed through the sprawling trial and the crazy turn of events after the trial ends.
