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.

家庭暴力，枪支和集体射击。

枪支，家庭暴力（尤其是亲密伴侣杀人）和其他受害者之间的密切联系表明，优先采取措施减少家庭暴力肇事者使用枪支的措施也可以减少大规模枪击事件的发生。大多数大规模枪击事件与家庭暴力有关。Kivisto和Porter的当前研究调查了在家庭凶杀案中使用枪支是否会影响同一事件中其他人也会被杀的风险。较早的研究表明，家庭杀人通常通过既有的关系或与暴力行为的亲近关系扩大到与主要犯罪者或受害者有联系的其他受害者。Kivisto和Porter基于国家监视数据库，确认了先前的发现，更有限的研究。使用枪支与多重杀人罪受害的发生率增加相关，尤其是在家庭情况下。这表明，防止家庭暴力行为者购买或拥有枪支的其他法律，以及大力执行新的和现有的法律，可能会减少大规模枪击的发生率，而无论其他受害者在家里还是在家里。
