Over the course of one week, the Michigan Journal of Law Reform presented its annual Symposium, this year titled Reimagining Police Surveillance: Protecting Activism and Ending Technologies of Oppression. During this week, the Journal explored complicated questions surrounding the expansion of police surveillance technologies, including how police and federal agencies utilize their extensive resources to identify and surveil public protest, the ways in which technology employed by police is often flawed and disparately impacts people of color, and potential reforms of police surveillance technology. Before delving into these complicated questions, I presented remarks on the history of police surveillance in America to situate subsequent panel conversations on the topic.
