AAfter failing to stop Crawford from 'pulling the plug' on Jennifer, Willy is still dissatisfied. Because of the Double Jeopardy Clause, however, he knows that, regardless of any new evidence he might find, Crawford cannot be tried again for Jennifer's attempted murder. While in the office going over his papers, he and Detective Flores (Cliff Curtis) have a moment where Flores places his cell on Willy's desk then picks up Willy's phone by mistake. A light bulb goes on in Willy's head. He drives to Crawford's house where Crawford is packing for a vacation. Willy tells him that, even though it's too late now, he just noticed that both Crawford and Nunally had the same types of guns. He describes a scenario where Crawford switches their guns on the day he went to their hotel room then later shoots Jennifer with Nunally's gun. When Nunally arrives to negotiate and they both put down their guns, Crawford quickly switches them back while Nunally is momentarily distracted, having just seen Jennifer lying on the floor. Thus, it is Crawford's unfired gun that is seized as evidence, while Nunally's gun, the actual murder weapon, goes back into Nunally's holster and is carried out the door. Willy points out that, now that Jennifer is dead, he can prove his scenario by getting the bullet from her brain and matching it to Nunally's gun. Crawford reminds him that the Double Jeopardy Clause prevents him from being tried twice for the same crime. Willy points out that his first trial was for 'attempted murder', but now that he has pulled the plug on Jennifer, he can be tried for first degree murder. In the final scene, Crawford's new trial begins with Willy Beacham as the prosecuting attorney.
ACrawford knew that Nunally was LAPD's Hostage Negotiator, which is why he set up a supposed hostage situation. When Crawford is speaking on the payphone prior to shooting his wife, he asks if Nunally is working at the time. Although Nunally is not in at the moment, Crawford is informed that he will be on duty at 6 PM, providing Crawford with a time frame for the shooting. When Nunally arrives at the scene and phones Crawford, he identifies himself as the Hostage Negotiator, so Crawford's plan is set in motion.
