Chicago-area police departments assisted Homeland Security Investigations (HSI) in surveilling Minnesota activists who oppose ICE, according to reporting by WIRED.

Local-Federal Surveillance Collaboration

The report details cooperation between local police agencies in the Chicago area and HSI, the investigative arm of the Department of Homeland Security. According to WIRED, Chicago-area police departments helped HSI spy on anti-ICE activists based in Minnesota.

Civil Liberties Concerns

The arrangement raises questions about the role of local law enforcement in federal surveillance of political activity, a subject of ongoing debate over civil liberties and the boundaries between local policing and federal immigration enforcement.
