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.
The 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.
Municipal court practices likewise cause disproportionate harm to African Americans. 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.
City officials have frequently asserted that the harsh and disparate results of Ferguson's law enforcement system do not indicate problems with police or court practices, but instead reflect a pervasive lack of "personal responsibility" among "certain segments" of the community. Our investigation has found that the practices about which area residents have complained are in fact unconstitutional and unduly harsh. But the City's personal-responsibility refrain is telling: it reflects many of the same racial stereotypes found in the emails between police and court supervisors. This evidence of bias and stereotyping, together with evidence that Ferguson has long recognized but failed to correct the consistent racial disparities caused by its police and court practices, demonstrates that the discriminatory effects of Ferguson's conduct are driven at least in part by discriminatory intent in violation of the Fourteenth Amendment.
Community Distrust
Since the August 2014 shooting death of Michael Brown, the lack of trust between the Ferguson Police Department and a signifigant portion of Ferguson's residents, especially African Americans, has become undeniable. The causes of this distrust and division, however, have been the subject of debate. Police and other City officials, as well as some Ferguson residents, have insisted to us that the public outcry is attributable to "outside agitators" who do not reflect the opinions of "real Ferguson residents." That view is at odds with the facts we have gathered during our investigation. Our investigation has shown that distrust of the Ferguson Police Department is longstanding and largely attributable to Ferguson's approach to law enforcement. This approach results in patterns of unnecessarily aggressive and at times unlawful policing;
