The purpose of the present study is to determine if there is a relationship between red flag laws and mass shootings. Mass shootings may be averted if the potential shooter’s firearms are seized per a warrant emanating from a red flag statute. Using a fixed effects model and a propensity score matching model, it was found that red flag laws are not significantly related to the number of mass shooting victims (killed and injured). One potential reason for this result is the rarity of mass shootings and the infrequency with which red flag laws are used. Data used in the present study are for the period 1999 to 2020. Mass shootings data were obtained from the Mother Jones mass shooting database. The present study is the first study in the English language literature to examine the relationship between red flag laws and mass shootings.

本研究的目的是确定红旗法与大规模枪击事件之间是否存在关系。如果根据红旗法规的逮捕令扣押潜在枪击者的枪支，则可能会避免大规模枪击事件。使用固定效应模型和倾向得分匹配模型，发现红旗法与大规模枪击受害者（死亡和受伤）的数量没有显着相关。造成这一结果的一个潜在原因是大规模枪击事件很少发生，而且红旗法很少被使用。本研究使用的数据为 1999 年至 2020 年期间的数据。大规模枪击事件数据来自 Mother Jones 大规模枪击事件数据库。本研究是英语文献中第一项探讨红旗法与大规模枪击事件之间关系的研究。
