Briscoe and Green investigate a fatal dog attack in Central Park. They trace the killer canine to a dog fighting ring controlled by a prison inmate. McCoy and Southerlyn bring manslaughter charges against the convict's lawyer, who owned the dog. McCoy tries to convince the jury by showing them the murder weapon: the snarling, barking pit bull. We're talking about Law & Order season 12 episode 1 "Who Let the Dogs Out?" Our returning guest is comedian Brandi Brown. This episode is inspired by the 2001 death of Diane Whipple.
