This paper uses a surge in stop and search operations following a high-profile murder to look at their effect on recorded crime. Difference-in-difference estimates using detailed geocoded data at the street-level suggest a doubling to trebling of the number of searches in streets close to the place of the murder. IV estimates on the effects of stops and searches on crime suggest little effect on property crime, weapons offences and violent crime or drug offences. Some specifications find reductions in anti-social behaviour, suggesting that any effects on crime are due to an increased police presence on the streets.

拦截和搜查会减少犯罪吗？来自街头数据的证据和高调犯罪后的行动激增

本文利用在一场备受瞩目的谋杀案之后激增的拦截和搜查行动来研究它们对记录在案的犯罪的影响。使用街道级别的详细地理编码数据的差异差异估计表明，在靠近谋杀地点的街道上的搜索次数增加了一倍至三倍。IV 对拦截和搜查对犯罪的影响的估计表明，对财产犯罪、武器犯罪和暴力犯罪或毒品犯罪的影响很小。一些规范发现反社会行为有所减少，这表明对犯罪的任何影响都是由于街头警察的增加。
