Nightly confrontations occurred between protestors and officers outside of the Seattle Police Department's (SPD's) East precinct in the aftermath of George Floyd's murder. On June 8, 2020, the SPD abandoned the East precinct in an attempt to calm the situation. Following closure of the precinct, the Capitol Hill Occupation Protest (CHOP) took hold in the surrounding 6-block area. The CHOP occupation lasted until July 1, 2020. Over this time period, CHOP operated as an autonomous zone, with police officers not patrolling and generally not responding to calls for police service within the area. We used the microsynthetic control group method to analyze the effect of CHOP on crime during the 24-day occupation. Results indicate crime significantly increased in the CHOP zone, the encompassing two-block area, and the overall East precinct service area.

西雅图无警察 CHOP 区对犯罪的影响：微合成控制评估

乔治·弗洛伊德（George Floyd）被谋杀后，西雅图警察局（SPD）东区外的抗议者和警官每晚都会发生冲突。2020 年 6 月 8 日，社民党放弃了东区，试图平息局势。在该区域关闭后，国会山占领抗议 (CHOP) 在周围的 6 个街区区域举行。CHOP 的占领一直持续到 2020 年 7 月 1 日。在此期间，CHOP 作为一个自治区运作，警察不巡逻，通常不响应该地区内的警务电话。我们使用微合成对照组方法来分析 CHOP 在 24 天占领期间对犯罪的影响。结果表明，CHOP 区（包括两个街区的区域）的犯罪率显着增加，
