Using open-source data from the Gun Violence Archive (GVA), we analyze national- and state-level trends in fatal and nonfatal firearm assaults of U.S. police officers from 2014 to 2019 ( = 1,467). Results show that (a) most firearm assaults are nonfatal, (b) there is no compelling evidence that the national rate of firearm assault on police has substantially increased during the last 6 years, and (c) there is substantial state-level variation in rates of firearm assault on police officers.
GVA has decided strengths relative to existing data sources on police victimization and danger in policing. We consider the promises and pitfalls of this and other open-source data sets in policing research and recommend that recent state-level improvements in use-of-force data collection be replicated and expanded to include data on violence against police.
利用来自枪支暴力档案(GVA)的开源数据,我们分析了2014年至2019年美国警察遭遇致命和非致命枪支袭击的全国及州级趋势( = 1467)。结果显示:(a)大多数枪支袭击为非致命性的;(b)没有令人信服的证据表明过去6年全国范围内警察遭枪支袭击的比率大幅上升;(c)警察遭枪支袭击的比率在州级层面存在很大差异。
相对于现有的关于警察受害情况和警务工作危险性的数据源,GVA具有显著优势。我们考量了这一数据集及其他开源数据集在警务研究中的前景与缺陷,并建议将近期州级层面在使用武力数据收集方面的改进措施进行推广,纳入针对警察暴力行为的数据。
