Mass Murderers in White Coats documents the mass murder of "mental patients" by psychiatry in Nazi Germany, which served as a precursor ideologically and logistically for the later extermination of six million Jews and other victims of Nazi persecution in concentration camps. Comprehensive research — with extensive notes — is used to illustrate the common roots of psychiatric practice in Germany and the United States, a history that includes eugenics and torturous, dehumanizing, and sometimes fatal "treatments." The book also includes an ex-"mental patient's" perspective on psychiatric oppression, interviews with psychiatrists (members of the American Psychiatric Association) that practiced or were trained in Germany during the Nazi regime, and a history of organized resistance to psychiatric oppression by its victims — the psychiatric inmates liberation movement.
