The Black Lives Matter (BLM) movement was a prominent social movement largely focused on raising awareness of and reducing police use‐of‐force and fatal interactions with police. However, opponents of the movement have feared it could lead to decreased proactive policing and increased crime. Using a state‐by‐month fixed effects model, I find evidence that an additional protest in the preceding month leads to a decrease of .225 fatal interactions between Blacks and police per 10 million Black population. In addition, I find no evidence supporting increased crime or arrests as a result of the BLM movement. (JEL J15, D91, Z13)

黑生命的物质抗议，致命的警察互动和犯罪

黑人生活（BLM）运动是一项杰出的社会运动，主要致力于提高人们的认识并减少警察使用武力和与警察的致命互动。但是，运动的反对者担心这可能导致主动警务减少和犯罪增加。使用逐月固定影响模型，我发现有证据表明，上个月的另一次抗议活动导致每1000万黑人人口中黑人与警察之间的致命互动减少了0.225。此外，我发现没有证据支持BLM运动导致犯罪或逮捕增加。（ JEL J15，D91，Z13）
