It recounts the evolution of gun politics and policy throughout the twentieth century, explains the positions and activities of organizations and activists on both sides of the gun debate, details notorious school shootings ranging from Columbine to Parkland, and explores the potential impact of the Never Again Movement on American gun policy at the state and federal levels.
