On 'Rizzoli & Isles' (Mon., 10PM ET on TNT), a dirty cop (Bobby) has trapped Detective Jane Rizzoli and her colleague and friend Maura Isles inside the Boston police station. When Bobby decides to escape, he thinks dragging Rizzoli along with him is a good idea.

It does start out that way: Her body sufficiently blocks his from the vigilant officers standing outside. No one can get a clean shot at him without endangering Rizzoli. "Drop the gun, Bobby! Don't make it worse on yourself -- let her go!" shouts Detective Korsak.

Rizzoli screms, "Shoot him! Just shoot him!" But nobody budges. The detective takes matters into her own hands -- and Isles witnesses the horrific turn of events.
