In a white-walled interrogation room in a small Virginia police station last June, two detectives were trying to get Herson Torres to crack. Surveillance video tied him to two attempted bank robberies in the area during the past week. The skinny 21-year-old didn’t have a criminal record and seemed nervous, but he wasn’t talking. The detectives showed him pictures of his brother and father. They told Torres he could be sent to prison for as many as 25 years.
