Criminal Minds: The Psychology of the World's Deadliest Killers

The FBI Behavioral Science Unit. The organized/disorganized typology. The four killer categories — psychopathic, organized, disorganized, mission-oriented, hedonistic, power-seeking. Dennis Rader's documented pre-crime psychology. This book examines what decades of criminal psychology research has revealed about the minds behind lethal violence — and arrives at the most important and most uncomfortable conclusion: the distance between killers and non-killers is smaller than the monster narrative suggests.
