<p>The objective of the study is to examine whether police responses to public protests in the USA during the summer of 2020 were racially biased. Police were both more present and more violent at public demonstrations involving themes of racial justice, once controlling for location, protest size, and protester activities. Researchers coded police and protestor behaviors at all 1862 protests in 27 representative mid-sized US cities over a 7-month window, with duplicative coding and strong inter-rater reliability tests to minimize and evaluate researcher bias. Probit and endogenous treatment regression analysis control for context including protestor behaviors while treating police presence and various levels of action (including arrests, tear gas, and rubber bullets) as modeled choices. Police responses show clear racial inequity in protest policing, above the expected police responses to protestor activities like property damage. Racial justice demonstrations were more likely to be policed, more likely to have subsequent police action, and more likely to result in arrests, all results significant at the highest level of statistical confidence. Protests by White extremists or events including counter-demonstrations were the least likely to encounter extreme crowd dispersal tactics like tear gas, pepper spray, and rubber bullets. The irony is that protests about racial injustice were themselves subjected to verifiable racial injustice.</p>
