Criminal Minds S05E14

In this crime series, a crack team of FBI profiles fly from Quantico to the focal point of the criminal activity of various serial killers. There they investigate the evidence from the crime scenes, compose a profile and try to prevent the next fatal strike.
Top brain is academic Jason Gideon, with his more by-the-book operational right hand man Aaron "Hotch" Hotchner. The still juvenile Dr. Spencer Reid is an erudite on everything except real life, Penelope Garcia a brilliant computer whiz who gets access to any database etc. As they are mobile, cooperation with local police and FBI agents is important but often poses jurisdictional and other problems, as do some witnesses and suspects.

Based in Quantico, Virginia, the Behavioral Analysis Unit (BAU) is a subsection of the FBI. Called in by local police departments to assist in solving crimes of a serial and/or extremely violent nature where the perpetrator is unknown (referred to by the Unit as the unknown subject or unsub for short), the BAU use the controversial scientific art of profiling to track and apprehend the unsub. Profiling entails coming up with basic characteristics of the unsub and the victims (referred to as the victimology), using evidence from the case and matching that information to historic precedents and psychological analyses as a means to solve the case. Because of the nature of the work conducted by the BAU - the work being time consuming and psychologically demanding - its members are fiercely loyal to the Unit and to its other members. Also because of the work's overall demanding nature, not many members of the BAU have been able to maintain a happy or stable family life. Written by Huggo
