From the DOJ report on Ferguson:

" .. with respect to speeding charges brought by FPD, the evidence shows not only that African Americans are represented at disproportionately high rates overall, but also that the disparate impact of FPD’s enforcement practices on African Americans is 48% larger when citations are issued not on the basis of radar or laser, but by some other method, such as the officer’s own visual assessment.

These disparities are also present in FPD’s use of force. Nearly 90% of documented force used by FPD officers was used against African Americans. In every canine bite incident for which racial information is available, the person bitten was African American.

... African Americans are 68% less likely than others to have their cases dismissed by the court, and are more likely to have their cases last longer and result in more required court encounters. African Americans are at least 50% more likely to have their cases lead to an arrest warrant, and accounted for 92% of cases in which an arrest warrant was issued by the Ferguson Municipal Court in 2013. Available data show that, of those actually arrested by FPD only because of an outstanding municipal warrant, 96% are African American.

Our investigation indicates that this disproportionate burden on African Americans cannot be explained by any difference in the rate at which people of different races violate the law. Rather, our investigation has revealed that these disparities occur, at least in part, because of unlawful bias against and stereotypes about African Americans. We have found substantial evidence of racial bias among police and court staff in Ferguson. For example, we discovered emails circulated by police supervisors and court staff that stereotype racial minorities as criminals, including one email that joked about an abortion by an African-American woman being a means of crime control."
