This brief serves to educate readers about the sovereign citizen movement, presenting relevant case studies and offering suggestions for measures to address problems caused by this movement. Sovereign citizens are considered by the Federal Bureau of Investigation (FBI) to be a prominent domestic terrorist threat in the United States, and are broadly defined as a loosely-afflicted anti-government group who believes that the United States government and its laws are invalid and fraudulent. Because they consider themselves to be immune to the consequences of American law, members identifying with this group often engage in criminal activities such as tax fraud, "paper terrorism", and in more extreme cases, attempted murder or other acts of violence. Sovereign Citizens is one of the first scholarly works to explicitly focus on the sovereign citizen movement by explaining the movement's origin, interactions with the criminal justice system, and ideology.

This timely reference examines the psychological and social phenomena of mass and serial murder, bringing scholarly depth to a frequently sensationalized subject. Its review of the literature features case studies of serial and mass murderers to expand on salient theories of evil, with biopsychosocial profiles highlighting core personality traits, particularly malignant narcissism, associated with psychopathy and its often deadly outcomes. The author's insightful analysis separates misconceptions from reality, poses questions for critical thinking and discussion, and offers realistic suggestions for prevention. Public fascination with these violent figures-the mystique of serial killers and their popularity in the entertainment media-is explored as well. Included in the coverage: * Public interest in mass and serial murder. * Concepts of evil: where it comes from, and why people kill.* Mass murder: classification, motivation, and typologies. * Serial murder: motivation and typologies. * Current trends in prevention, and areas for improvement. * Plus instructive case studies, both famous and less-known. Mass and Serial Murder in America is illuminating reading for undergraduate and graduate students and practitioners in social science disciplines such as criminal justice, criminology, social work, psychology, forensic psychology, and related fields. It will also find an audience among educators teaching courses in these areas, as well as interested laypersons.
