The strong association between firearms, domestic violence (particularly intimate partner homicide), and additional victimization suggests that prioritization of measures to decrease access to firearms to perpetrators of domestic violence may also reduce the incidence of mass shootings. The majority of mass shootings are associated with domestic violence. The current study by Kivisto and Porter examines whether the use of a firearm in domestic homicide affects the risk that others will also be killed during the same incident. Earlier studies have demonstrated that domestic homicide often extends to additional victims linked to the primary perpetrator or victim, either through a preexisting relationship or through physical proximity to the violence. Based on a national surveillance database, Kivisto and Porter confirm findings from earlier, more limited studies. Firearm use is associated with an increased incidence of multiple homicide victimization, especially in domestic situations. This suggests that additional laws to prevent those who perpetrate domestic violence from purchasing or possessing firearms, and vigorous enforcement of new and existing laws, may decrease the incidence of mass shootings, whether additional victims are inside or outside the home.
枪支、家庭暴力（特别是亲密伴侣杀人）和其他受害者之间的强烈关联表明，优先考虑减少家庭暴力实施者获得枪支的措施也可能会降低大规模枪击事件的发生率。大多数大规模枪击事件都与家庭暴力有关。基维斯托和波特的这项当前研究考察了在家庭杀人案中使用枪支是否会增加同一事件中其他受害者被杀的风险。早期的研究表明，家庭杀人案通常会延伸到与主要犯罪者或受害者有关的其他受害者，这些受害者要么通过先前存在的关系，要么通过与暴力的身体接近。基维斯托和波特基于一个全国性的监测数据库，证实了早期更有限的研究结果。枪支的使用与更多的多人受害发生率有关，特别是在家庭环境中。这表明，增加防止实施家庭暴力者购买或拥有枪支的法律，并大力执行新的和现有的法律，无论是在家庭内部还是外部，都可能会降低大规模枪击事件的发生率。
