前言用于研究警察凶杀案的最广泛的数据集--由联邦调查局保存的《补充凶杀案报告》(SHR)--是从自愿样本中收集的。材料和方法使用一个由记者管理的警察相关死亡数据库，我们发现SHR的警方凶杀案数据基本上是不完整的。这是由于各机构未报告和报告严重不足造成的。此外，我们的调查揭示了在数据中识别“受害者”和“违法者”的错误模式，并发现调查机构经常被错误地列为负责机构，这严重危及警察部门一级的分析。最后，存在样本偏差的证据表明，SHR数据系统不能代表所有警察部门，也不能代表大型警察部门。结论我们得出结论，SHR数据对于评估美国警察凶杀案的相关性具有可疑的价值，因为所有使用它的分析都将反映这些广泛的偏见和严重的低估。应停止为这些目的分析SHR数据。
IntroductionThe most widely used data set for studying police homicides—the Supplementary Homicide Reports (SHR) kept by the Federal Bureau of Investigation—is collected from a voluntary sample.Materials and MethodsUsing a journalist-curated database of police-related deaths, we find the SHR police homicide data to be substantially incomplete. This is due to both non-reporting and substantial under-reporting by agencies. Further, our inquiry discloses a pattern of error in identifying “victims” and “offenders” in the data, and finds that investigating agencies are often incorrectly listed as the responsible agency, which seriously jeopardizes police department-level analyses. Finally, there is evidence of sample bias such that the SHR data system is not representative of all police departments, nor is it representative of large police departments.ConclusionsWe conclude that the SHR data is of dubious value for assessing correlates of police homicides in the United States, as all analyses using it will reflect these widespread biases and significant undercounts. Analysis of SHR data for these purposes should cease.
