Three new books by sociologists—The Policing Machine by Tony Cheng, The Minneapolis Reckoning by Michelle Phelps, and The Danger Imperative by Michael Sierra-Arévalo—offer us a view into the state of US policing leading up to and following the racial reckoning of 2020. I read these books together through the lens of boundary work, examining what they tell us about the various projects that seek to maintain, expand, or change police jurisdiction over the production of public safety. Collectively, these books suggest that the police work to preserve and extend their extant role and power. Meanwhile, boundary work through movement mobilization and political systems has aimed to contain policing through law and policy, shrink policing within municipal service systems, and replace policing through community-led models of safety. These projects point us toward important areas of inquiry in efforts to understand whether and how policing can change.
