Interesting book by an ex-FBI agent that explores the minds of various serial killers and exposes the procedures and processes that led to their capture.

I enjoyed this book, especially the chapters where Ressler describes how the profiling contributed to capturing and convicting murderers. I would recommend this book to anyone currently working in law enforcement. I would have enjoyed the book more and rated it higher if a few changes had been made: -Focus much more on how the police actually figured out who the murderers were and how they built the case against them, including many more details of the clues, techniques, interviews, and interrogations. -Acknowledge that just like psychiatrists were duped by serial murderers, so might profilers have been regularly duped. -Leave out his inconsistent beliefs on sentencing. -Leave out that he testified on Dahmer's behalf... or better yet, not have done so.
