Gun violence is a public health crisis in the United States. While the largest share of firearm-related deaths are suicides, most media coverage of gun violence focuses on homicides, particularly highly lethal mass shootings in public spaces. In the aftermath of one of these tragedies, there often are demands to “do something” to prevent the next one. In our forthcoming article, “Mass Shootings in the United States: Prevalence, Policy, and a Way Forward,” we highlight policies and proposals offered by legislators and advocates to prevent mass shootings from happening and reducing their lethality if they do occur.
