研究摘要 我们使用联邦调查局补充凶杀报告和其他公开数据库中的数据来计算 1984 年至 2017 年州级致命大规模枪击事件的年发生率。使用负二项式回归模型来估计关键枪支法的变化与致命的大规模枪击事件之间的关联。手枪购买者许可法和大容量弹匣（LCM）禁令与致命大规模枪击事件的发生率大幅下降有关。其他通常提倡作为大规模枪击事件解决方案的法律——全面背景调查、攻击性武器禁令以及放松对平民隐蔽携带枪支的管制——与致命的大规模枪击事件无关。政策影响 我们的研究结果表明，要求枪支购买者通过指纹支持的背景调查程序获得许可的法律和禁止 LCM 的法律是减少致命大规模枪击事件的最有效枪支政策。
Research Summary We used data from the FBI's Supplemental Homicide Reports and other publicly available databases to calculate state-level annual incidence of fatal mass shootings for 1984-2017. Negative binomial regression models were used to estimate the associations between changes in key gun laws and fatal mass shootings. Handgun purchaser licensing laws and bans of large-capacity magazines (LCMs) were associated with significant reductions in the incidence of fatal mass shootings. Other laws commonly advocated as solutions to mass shootings-comprehensive background checks, assault weapons bans, and de-regulation of civilian concealed carry of firearms-were unrelated to fatal mass shootings. Policy Implications Our findings suggest that laws requiring firearm purchasers to be licensed through a background check process supported by fingerprints and laws banning LCMs are the most effective gun policies for reducing fatal mass shootings.
