Effects of domestic violence policies, alcohol taxes and police staffing levels on intimate partner homicide in large US cities

Reducing access to firearms for DVRO defendants, increasing police staffing levels and allowing the warrantless arrest of DVRO violators may reduce the city-level risk of IPH. Future research should evaluate factors that may mediate the effect of these laws and increased police staffing levels on IPH to determine whether there are opportunities to increase their protective effect. Further research is needed on firearm law implementation to determine why the other tested laws were not found effective.
