The Practice (1997) : 5x22

Helen is enraged by Richard Bay's execution and determined to punish Jackie Cahill and all other responsible parties. She makes a deal with Cahill, offering him immunity on Bay's murder plus the added bonus that she won't announce that he's a snitch and release him into the general prison population if he gives up the shooter. He agrees. After the shooter has been killed by police, Helen reneges on the deal, claiming Jackie hasn't fulfilled the terms of the agreement. Jackie's lawyer protests and drags Helen into court. Meanwhile, Rebecca and Jimmy defend a man on charges that he strangled his wife. Rebecca is adamant about the man's innocence, arguing that the only reason he's being prosecuted is because he was stunned by his wife's death and gave the investigating officer erroneous information. Rebecca and Jimmy are shocked to later learn that their client has a history of strangling both women and chickens.
