The Franchise, Policing, and Race: Evidence from Arrests Data and the Voting Rights Act
研究发现，1965年《投票权法案》实施后，在更多黑人新获选举权且受法案覆盖的县，黑人逮捕率相比未覆盖的南方县有所下降，而白人逮捕率无此变化，表明投票权结合选举问责能改善警察对少数族裔的对待。
This paper investigates the relationship between the franchise and policing. We find that, following the Voting Rights Act of 1965, Black arrest rates in counties that both had more newly enfranchised Blacks and were covered by the legislation fell, compared to similar Southern counties that were not covered. We document no corresponding patterns for White arrests. Our results are driven by arrests by sheriffs, who are always elected, and by less serious offenses. These results indicate that voting rights, when combined with electoral accountability, lead to improved treatment of minority groups by police.
