Law & Order: Trial by Jury S01E10 - Blue Wall

Kibre is handed a political bombshell when she is asked to prosecute two police officers, Petro and Tolbert for their murky roles in the murder of a gay prisoner who was fatally sodomized with a police nightstick -- but she clashes with Detective Ravell who confronts the "the blue wall" in his search for truth. Under federal pressure for a conviction, a conscience-stricken Ravell causes more problems when he tries to protect one of the cops and his young family by withholding vital evidence.
