Using the Law Enforcement Officers Killed and Assaulted (LEOKA; 2002-2011) database, we examined the life-saving effectiveness of body armor while adjusting for a range of confounders not assessed in previous studies. Among the 637 officers who were shot by a firearm at the torso, those who wore body armor were 76% less likely to be killed than those who did not wear armor, controlling for an array of individual and incident characteristics. A number of factors influenced officers' armor wearing behavior include age, BMI, rank, geographic region, and type of assignment. Results will inform law enforcement agencies in assessing gaps in their current policy and help focus limited resources to encourage armor wearing. The investigation of other factors that influence police officers' chance of surviving a gun shooting (while controlling for body armor) will also have important implications for policies related to sending backup officers to police shootings, emergency response, and other critical areas.
利用执法人员伤亡及受袭情况（LEOKA；2002 - 2011年）数据库，我们在对先前研究未评估的一系列混杂因素进行调整的同时，考察了防弹衣的救生效果。在637名躯干被枪支击中的警察中，在控制了一系列个人和事件特征后，穿着防弹衣的警察比未穿防弹衣的警察被杀可能性低76%。影响警察防弹衣穿着行为的一些因素包括年龄、体重指数、警衔、地理区域和任务类型。研究结果将为执法机构评估其当前政策中的差距提供参考，并有助于集中有限资源以鼓励穿着防弹衣。对影响警察枪击幸存几率的其他因素（在控制防弹衣因素的情况下）进行调查，也将对与派遣支援警察处理警察枪击事件、应急响应及其他关键领域相关的政策产生重要影响。
