This third edition of Violence in America is a completely new book with all 12 chapters of this volume written specifically for it. These chapters survey a wealth of new research on the long-term dynamics of murder and other crimes of violence. The contributors identify and diagnose the circumstances of recurring epidemics of violent crime that have swept the social landscape of the United States in the last 150 years, including waves of immigration, the social dislocation of war, and growing concentrations of urban poverty. They also evaluate the traits of political assassins and assess the pros and cons of gun control for reducing crime.
