Unwritten Rules

When a robber flees after a jewelry store heist, Jamie and his newly assigned partner Edie Janko (Vanessa Ray) arrive on the scene just in time to hear a gunshot that kills another officer. The suspect escapes through a nearby park. Danny and Maria are assigned the case, and Danny is certain that a man named Angelo (Malcolm Goodwin) who was witnessed at both the jewelry store and in the park, is the shooter. When an elderly eyewitness struggles to identify Angelo in a photo lineup, Danny “helps” her, and she later picks him out of a live lineup. Erin is skeptical that the woman's testimony will survive cross-examination in court, and is forced to let Angelo go. This gets her in hot water with her family, her boss and most of the NYPD rank-and-file. Officers thus stage a “blue flu” situation by refusing to appear at other court cases involving Erin's office, forcing Frank to order an end to the blue flu. In the end, Erin and Danny team up to stage a situation wherein Angelo can confess and get a deal for only seven years in prison. They then trick him into declining the deal (with Angelo unaware that his confession is still binding), and they book him for Murder One.
