Gun-shooting bank employee trips up Kibre when he represents himself in court -- When a bank worker (guest star Jeff Perry) casually shoots a customer to death and wounds others, the seemingly mentally unstable man runs rings around an exasperated A.D.A. Kibre (Bebe Neuwirth) in court when he asks to defend himself and exploits his claim of extreme emotional distress due to the tragic death of his son. But Kibre and Gaffney (Amy Carlson) must regain their footing before the jury through old-fashioned detective work which reveals critical holes in the murderer's persistent claim that he has been victimized by everyone. Carey Lowell guest stars as Judge Jamie Ross. Fred Dalton Thompson, Kirk Acevedo and Scott Cohen (NYPD Blue) also star.
