The Data Tells a Story
Immigration enforcement happens in two fundamentally different ways. In cooperative jurisdictions, when local police arrest someone for an unrelated crime, ICE can lodge a detainer—a request to hold that person briefly so ICE can take custody when local charges are resolved. The transfer happens inside a jail, controlled and administrative. In non-cooperative sanctuary jurisdictions, local authorities refuse these detainers. This forces ICE to locate and arrest people in the community—at homes, workplaces, during traffic stops, and on streets. One method happens behind secure walls. The other happens in public—where crowds form, tensions escalate, and split-second decisions can turn deadly.
Between January 20 and October 15, 2025, ICE made more than 217,000 arrests in the country’s interior (Prison Policy Initiative analysis of ICE data). The majority of those arrested had either prior criminal convictions or pending criminal charges, while approximately 33% were arrested for immigration status violations only. It is not known how many individuals in this latter category were arrested in conjunction with another arrest or were subject to final deportation orders.
