Mass Shootings in the United States: Prevalence,Policy,and a Way Forward

Abstract

Mass shootings in the U.S. elicit strong reactions and often are followed by demands for preventive or ameliorative policy action. Often, however, little change is made to policy, and the cycle of tragedy and passionate discourse is left to start anew. We assess the efficacy of a range of specific policies that may help to prevent mass shootings or mitigate their harms: we review empirical evidence on their effectiveness and consider arguments that both proponents and opponents of these policies bring to bear on the public discourse. We conclude that extant evidence and policy ideas that are on the table now can, in fact, point to a productive way forward: we argue for a proactive, layered approach to policy implementation that minimizes risks and impacts and capitalizes on effective interventions that enjoy broad public support.
