论文摘要
我们在通过第47号提案之前和之后检查了加利福尼亚州圣莫尼卡的犯罪模式,这是一项2014年的倡议,将一些非暴力重罪重新分类为轻罪。我们还研究了2016年开放四个新的轻型火车站的开放,以及2018年底开始的更多基于社区的警务影响犯罪。对重新分类(盗窃案,欺诈,伪造,伪造,接收/拥有被盗特性)和非分类犯罪进行了一系列统计分析,通过探究2006年至2019年的公开数据库。我们比较了在通过47号提案47,城市和八个社区内和之后的数据进行比较。在新运输站的450米半径内进行了类似的分析。在颁布第47号提案后,每月重新分类的犯罪报告的报告在整个城市范围内增加了约15%,2018年底观察到大幅下降。市区的总体增长最大。据报道,盗窃案的发生率在整个城市加剧。服务开始后,包括市中心在内的两个新的火车站报道,附近的犯罪率很大。尽管命题47通过后,报告的重新分类犯罪的数量增加了,但不受新法律影响的人的数量减少或保持恒定,这表明47命题对圣莫尼卡的犯罪产生了强烈影响。据报道,与采取新的警务措施同时采取了加强外展和巡逻的新警务措施同时减少。这些发现可能与执法和决策者有关。需要确认长期趋势所需的后续研究可能会受到巨大改变社会条件的Covid-19-19大流行的影响。
We examine crime patterns in Santa Monica, California before and after passage of Proposition 47, a 2014 initiative that reclassified some non-violent felonies to misdemeanors. We also study how the 2016 opening of four new light rail stations, and how more community-based policing starting in late 2018, impacted crime. A series of statistical analyses are performed on reclassified (larceny, fraud, possession of narcotics, forgery, receiving/possessing stolen property) and non-reclassified crimes by probing publicly available databases from 2006 to 2019. We compare data before and after passage of Proposition 47, city-wide and within eight neighborhoods. Similar analyses are conducted within a 450 meter radius of the new transit stations. Reports of monthly reclassified crimes increased city-wide by approximately 15% after enactment of Proposition 47, with a significant drop observed in late 2018. Downtown exhibited the largest overall surge. The reported incidence of larceny intensified throughout the city. Two new train stations, including Downtown, reported significant crime increases in their vicinity after service began. While the number of reported reclassified crimes increased after passage of Proposition 47, those not affected by the new law decreased or stayed constant, suggesting that Proposition 47 strongly impacted crime in Santa Monica. Reported crimes decreased in late 2018 concurrent with the adoption of new policing measures that enhanced outreach and patrolling. These findings may be relevant to law enforcement and policy-makers. Follow-up studies needed to confirm long-term trends may be affected by the COVID-19 pandemic that drastically changed societal conditions.
