Mass shootings and police shootings have spurred calls for authorities to take action to reduce the violence. But policymakers may be stymied by the dearth of public health research into both gun violence and deaths that involve the police. One big obstacle: congressional restrictions on funding of such research at the Centers for Disease Control and Prevention.
Right now, the CDC studies all kinds of violence. There's a program on child abuse and youth violence, and the public health agency collects data on suicides and sexual assaults.
