This study investigated the effect of an expanded police station citation release policy enacted in Washington, DC in March 2020 on eight types of crime: homicide, sex abuse, robbery, assault with a dangerous weapon, burglary, motor vehicle theft, theft from motor vehicles, and other theft. Monthly-level multivariate time series analyses employed data from 2013-2022 and accounted for the relationship between crime, arrests, and the jail population. The expanded policy was hypothesized to increase certain property crimes based on the new guidelines, but results indicated the policy modification was associated with changes in citywide crime counts for one type of crime: homicide.

抓获后释放：测试传票释放政策对华盛顿特区犯罪的影响

本研究调查了 2020 年 3 月在华盛顿特区颁布的扩大警察局传票发布政策对八种犯罪类型的影响：杀人、性虐待、抢劫、使用危险武器袭击、入室盗窃、机动车盗窃、机动车盗窃，以及其他盗窃行为。月度多元时间序列分析采用 2013 年至 2022 年的数据，并解释了犯罪、逮捕和监狱人口之间的关系。根据新的指导方针，扩大的政策被假设会增加某些财产犯罪，但结果表明，政策修改与全市范围内一种犯罪类型的犯罪计数变化有关：凶杀。
