GunsBroader gun restrictions reduce intimate partner homicides

State laws that restrict gun ownership among domestic abusers and others with violent histories appear to significantly reduce intimate partner homicides, indicates a groundbreaking national study. The findings, which come on the heels of the Texas church massacre by a man with a history of domestic violence, suggest state laws with broader gun restrictions are more effective at preventing homicides among romantic partners – even if the laws do not exclusively target domestic abuse.

State laws that restrict gun ownership among domestic abusers and others with violent histories appear to significantly reduce intimate partner homicides, indicates a groundbreaking national study led by a Michigan State University researcher.

The findings, which come on the heels of the Texas church massacre by a man with a history of domestic violence, suggest state laws with broader gun restrictions are more effective at preventing homicides among romantic partners – even if the laws do not exclusively target domestic abuse.

MSU notes that currently, thirteen states and federal law prohibit gun purchases by individuals convicted of domestic violence; the study finds that states that extend this ban to people convicted of any violent misdemeanor experience 23 percent fewer intimate partner homicides.

Reductions in domestic partner homicides were also more pronounced when gun-restriction laws included dating partners (not just spouses or ex-spouses) and a requirement that abusers surrender their firearms.

April Zeoli, MSU associate professor of criminal justice and primary investigator on the research, said broader gun-restriction laws could potentially save the lives of hundreds of domestic violence victims every year. Of the 1,352 intimate partner homicides in 2015, 55 percent were committed by firearms, according to the FBI.

“The evidence from this study and previous research highly suggests that firearm restrictions work to reduce intimate partner homicides and that laws need to be comprehensive when we think about populations most at risk for committing intimate partner violence,” Zeoli said. “Expanding restrictions from those who have been convicted of domestic violence to those who have been convicted of any violent misdemeanor, and including dating partners in domestic violence firearm laws, would likely result in even greater reductions.”

The study was published in the American Journal of Epidemiology.

The researchers studied the effects of firearm restrictions on intimate partner homicides in the 45 states with available data over a 34-year period, 1980 to 2013.
