Whoever Fights Monsters by Robert K. Ressler & Tom Shachtman

Criminal profiling is a hot topic with maybe the most unglamorous of foundations. Built on the commission of violent sexual homicides and the insights gained from the study of such offenders, the FBI's Behavioral Analysis Unit (formerly the Behavioral Science Unit) was formed nearly 40 years ago.

Robert Ressler is an FBI agent who studied these crimes and criminals and was instrumental in the formation of the BSU, which has inspired countless TV shows and movies like The Profiler, Mindhunter, Criminal Minds, The Silence of the Lambs, The Prodigal Son...and the list goes on.

Ressler gives history on the unit, which includes the creation of VICAP and the NCAVC. The NCAVC, or National Center for the Analysis of Violent Crime is a department of the FBI that aids law enforcement agencies in the prevention, understanding, and investigation of violent crime. VICAP, or the Violent Criminal Apprehension Program, is a national database available to law enforcement to log and query information about violent crimes. These are resources available to law enforcement that didn't exist when Ressler was first involved in the FBI. Ressler details his career and how these programs were created in part through his work and efforts.

Ressler's career with the FBI was in the 1970s and 1980s. Little was known about serial killers or serial sexual homicide. Ressler was good enough at his job that he could ask forgiveness rather than permission and accomplish things that would likely get him fired today. This includes backdating memos and interviewing serial killers in prison without official authorization. 

But his efforts paid off. By interviewing offenders like Jeffrey Dahmer, Charlie Manson, and Ed Kemper, Ressler was able to gain insight into what made them, and people like them, tick. His expertise allowed him involvement in aiding numerous cases with his spot on profiles and he was a consultant for various projects, notably with Thomas Harris, author of The Silence of the Lambs. 

Ressler lived in a different time than we are in now, but the BAU endures today. I wonder how it has evolved over the decades and if the analysis of serial killers is as relevant as it is today or if other types of killers, like terrorists and school shooters, have come into prominence in the unit's study. But there's no denying the groundwork Ressler laid and the sheer fascination this book provides in his tales of serial killers from this time.
