Self Defense

Sully is accused of killing a fellow cop when a routine visit goes badly wrong. Guy steps in to help his friend when Sully's story of self defense is not supported by the evidence.

Full Recap
Responding to a call to apprehend a suspect, Sully is surprised to find Officer Tom Casey at the scene. Casey had been a detective, but had lost his shield when Sully turned him in to Internal Affairs for accepting bribes. Casey, his partner Ruiz and Sully go in to arrest the suspect, but he pulls a gun and chaos ensues. When Guy arrives, Casey is dead...shot by Sully. Sully claims that Casey tried to kill him and Sully fired in self defense, but Casey's gun was not fired. As Sully is suspended and facing jail time, Guy works to clear Sully's name. Since Casey's service weapon was not fired, Guy looks for another gun. He finds the bullet first, but the evidence shows Casey could not have fired it. The solution comes with a pair of uniform pants. Meanwhile, Guy is relieved to learn the mysterious male stranger Barbara has been meeting with is her brother.
