State background checks and firearms homicides

This study examined the relationship between state firearms homicides and background checks for firearms purchases. Controlling for economic and social conditions, the estimated number of firearms in circulation, offenders under community supervision, and violent crime it was found that states with less stringent background checks on firearms purchases were significantly associated with firearms homicides. The large number of firearms circulating within the United States makes it likely that a motivated-but ineligible-person could obtain a firearm over the long-term in the secondary firearms market. Effective state background checks, however, may temporarily frustrate an unauthorized person from obtaining a firearm that, in turn, may contribute to lower firearms homicide rates. Implications for further research are examined.
