While he and Carrie are chasing him in a dark alley, Roe shoots and kills David Jacobs, the suspect in the murder of a local drug dealer. Though Roe claims that Jacobs drew his gun first, no weapon is found, forcing the department to open an investigation into the shooting. When a distraught Clay Jacobs arrives at the precinct demanding to speak with the cop who killed his son, he takes four people hostage – including Nina and Officer Bill Daniels. When Lewis Martin, a tough and inflexible cop, is assigned to negotiate with Clay, Al is worried that he could provoke a violent conclusion to the situation. As Clay barricades himself inside an office and Lewis sets up his team outside, Carrie and Mike try to find the gun Roe claims he saw Jacobs carrying. However, Roe’s defense is undermined when Joanne can’t find any gunpowder residue on the victim’s body. As Carrie looks to Clay’s teenage daughter Kim for help, the cops hope that the anonymous caller who reported the shooting of Jacobs can corroborate Roe’s story. When Carrie and Mike track him down, he says he didn’t see Jacobs carrying a gun but does remember spotting a homeless junkie retrieving something from a dumpster after the shooting. After Clay learns that the police haven’t found a weapon, he lashes out when Daniels tries to overpower him, beating the cop senseless and threatening to kill him if he can’t speak with Roe. As Lewis prepares to use force to free the hostages, Clay buys some time by releasing Daniels. Questioning his decision to shoot Jacobs, Roe forces his way inside the room with Clay. As the hostage team prepares to rush in, Clay releases everyone but Roe. After finding the junkie who was seen in the alley, Carrie’s memories of the crime scene lead her to conclude that he pawned a gun that Jacobs stashed in the dumpster before he was shot. When she tracks down the weapon, she discovers that it belongs to his dad. But once Clay reveals that his son developed PTSD after serving in Afghanistan and could no longer shoot a gun, Carrie realizes that Roe shot David as he was disposing of the murder weapon in order to protect the person who really murdered the drug dealer – his sister Kim. When Carrie confronts her, Kim’s confession brings the hostage situation to an end. © 2012 Sony Pictures Television Inc. and CBS Studios Inc. All Rights Reserved.
