This opinion piece by policing experts Seth W. Stoughton, Ian T. Adams, Geoffrey P. Alpert, Gil Kerlikowske, Maureen Q. McGough, and Jeffrey J. Noble addresses federal immigration enforcement tactics under the Trump administration. The authors argue that the conduct of agencies like ICE and CBP has departed from established norms in policing in a way that has undermined public safety, particularly through fatal shootings. They contend that these actions—marked by poor planning, aggressive field tactics, and a disregard for accountability—are not just unprofessional but dangerously authoritarian, threatening public safety and the legitimacy of policing itself.
