Since everyone's big takeaway seems to be "there's no racial bias in policework, end of story," these two passages should be of particular interest:
On non-lethal uses of force, blacks and Hispanics are more than fifty percent more likely to experience some form of force in interactions with police.
Our results have several important caveats. First, all but one dataset was provided by a select group of police departments. It is possible that these departments only supplied the data because they are either enlightened or were not concerned about what the analysis would reveal. In essence, this is equivalent to analyzing labor market discrimination on a set of firms willing to supply a researcher with their Human Resources data!
Also note that the paper has not undergone peer review or other independent vetting.
