Schools, theaters, and malls used to be safe havens. Marathons were triumphal, not tragic. Today, public life is risky. Citizens are on edge, either calling for gun control or purchasing personal weapons of self-defense. In this timely book, prominent US and international authors examine gun violence in public life. They offer the latest data and analysis on topics such as comparative gun homicide rates, the efficacy of gun control, risks associated with gun ownership, concealed-carry data and policy, media and gaming violence, gender and guns, and school shootings. New insights are developed from a comparative case study of Canada, a country in which gun ownership is common but with a much lower rate of gun violence. Neither demonizing nor mythologizing guns, the contributors provide evidence-based analyses that shed light on policy directions and personal conduct.
