The Contagion of Mass Shootings: The Interdependence of Large-Scale Massacres and Mass Media Coverage

Mass public shootings have generated significant levels of fear in the recent years, with many observers criticizing the media for fostering a moral panic, if not an actual rise in the frequency of such attacks. Scholarly research suggests that the media can potentially impact the prevalence of mass...
