Peter Mancina, "On the Side of ICE: Policing Immigrants in a Sanctuary State" (NYU Press, 2025)

Dec 17, 2025
Peter Mancina, an anthropologist and visiting scholar at Rutgers Law School, dives into the complex relationship between local police and ICE, particularly in sanctuary states. He reveals how even immigrant-friendly policies can lead police to inadvertently assist federal enforcement. Using innovative body-worn camera ethnography, Mancina critiques traditional policing narratives and discusses how current sanctuary practices can complicate cooperation with ICE. He also offers insights on necessary reforms to strengthen immigrant protections amidst evolving enforcement tactics.
