3x17 - Profiler

Sam and Bailey get caught up in a jewel heist by a trio of mentally unbalanced crooks, named Randy, Kate and Stevie, that quickly turns into a hostage situation within the jewelry store. They struggle to profile the perpetrators and their relationships with one another before any lives are lost. While Sam tries to reason with the ringleader, Randy, to give up, John quarrels with the overzealous police commander outside who wants to catch or kill all the perpetrators even if it means that all hostages will be killed.
