The Impact of Affirmative Action Litigation on Police Killings of Civilians
Open accessAbstract
Although research has shown that court-ordered hiring quotas increase the number of minority police officers in litigated cities, there has been little insight into how workforce diversity, or lack thereof, may impact police violence against civilians.Using an event study framework, we find that the threat of affirmative action litigation reduces police killings of non-White civilians in the long-run.In addition, we find evidence of lower arrest rates for non-White civilians and more diverse police departments 25 years after litigation.Our results highlight the vital role that federal interventions have in addressing police behavior and the use of lethal force.

The demographic composition of the reference group confirms that Black individuals and men remain most affected, which reinforces how alternative crisis response models can reduce law enforcement contact among historically heavily policed populations.
“The demographic composition of the reference group, individuals processed by police, confirms that Black individuals and men remain most affected, which reinforces how alternative crisis response models can reduce law enforcement contact among historically heavily policed populations (Ba et al., 2021;Cox et al., 2024).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
