John Liebert is a Forensic Psychiatrist. He consulted on the Ted Bundy murders, the Atlanta Child Murders and the Green River Killer.
He specializes in studying mass shooters and has written many books on that subject. He is a strong advocate for helping veterans.
A couple years ago, Dr. Liebert asked me to write a foreword for a book, “Psychiatric Criminology-A Roadmap for Rapid Assessment”. I was honored to do so. His books are available here.
John also wrote one work of fiction, “The Palace Guard”. It can be found here.
