Active shooter incidents in schools cause widespread attention across the nation. Students, faculty, and staff on campuses could be involved with these shootings, as victims, perpetrators, etc.[1]. These gun-related crimes jeopardize school safety. From 1999 to 2024, there have been approximately 43 mass school shootings, with over 500 school shootings altogether. By definition, mass shooting is defined as any event where four or more people are shot with a gun, but not counting the perpetrator. By studying school shooting cases, we concluded that most of the time, the shootings occur inside the classrooms. Existing research that includes statistical analysis usually focuses on public mass shootings or just shooting incidents that have occurred in the past and there are hardly any articles focusing on school mass shootings. This leads to schools being more vulnerable to mass shootings in the future. In this research, we have gathered school shooting data from various resources to analyze the results. By interpreting these data and conducting various statistical analysis, this will ultimately help the law enforcement to better prepare for future school shootings.

翻译：校园内的活跃枪手事件引发全国广泛关注。学生、教职员工可能以受害者、施害者等身份卷入这些枪击事件[1]。此类涉枪犯罪严重危害校园安全。1999年至2024年间，美国共发生约43起大规模校园枪击事件，校园枪击事件总数超过500起。根据定义，大规模枪击事件指造成除行凶者外四人及以上遭枪击的任何事件。通过对校园枪击案例的研究，我们发现大多数枪击事件发生在教室内部。现有包含统计分析的研究通常聚焦于公共大规模枪击事件或既往枪击事件，鲜有专门针对校园大规模枪击的研究文献。这种研究缺口导致校园在未来可能更易遭受大规模枪击威胁。本研究通过整合多源校园枪击数据展开系统性分析。通过对这些数据的解读及多种统计分析，研究成果将最终助力执法部门更有效地应对未来可能发生的校园枪击事件。
