Illinois — Operation Midway Blitz vs. the Strongest Sanctuary Stack in the Country

IL

The Pattern

Illinois is the purest example of sanctuary-vs-federal conflict in the detention pipeline. The state has among the strongest protections in the country:

  • Way Forward Act (2021): Bans county jails from contracting with ICE for detention
  • 287(g) prohibition: Blanket ban on local law enforcement entering 287(g) agreements
  • Private detention ban: No private detention centers allowed
  • Courthouse protection law (Dec 2025): 1,000-foot buffer zone, $10K statutory damages for violations

In response, the Trump administration launched Operation Midway Blitz (Sep 9, 2025) — the largest targeted federal enforcement operation against a sanctuary city/state in history.

Operation Midway Blitz

  • Launched September 9, 2025, multi-agency surge covering all of Illinois + Lake County IN
  • DHS Secretary Noem personally traveled to Chicago when arrests passed 1,000 (Oct 2025)
  • By December 2025: 4,500+ arrests
  • Marshall Project analysis: most arrested did not have criminal records
  • ICE stated “we aren’t leaving Chicago” when Border Patrol pulled out (Nov 2025)
  • Illinois arrests among the nation’s highest in 2025

Broadview: Processing Center Turned De Facto Prison

The Broadview ICE facility (Cook County), designed as a processing center for 236 adults with 12-hour max holds, was converted into de facto detention:

  • June 2025: ICE quietly expanded max hold from 12 to 72 hours
  • Fall 2025: People held for up to three weeks
  • Nov 2025: Federal Judge Gettleman called it “really a prison,” issued 15-point TRO requiring bedding, food, water, showers, hygiene, attorney access
  • Residents live 600 feet from facility; village estimated $700K+ in losses

This mirrors the warehouse conversion pattern — rather than building new detention (blocked by state law), ICE repurposed existing infrastructure beyond its design capacity and legal classification.

Cook County SA: Charging Protocol for ICE Agents

On February 19, 2026, Cook County State’s Attorney Eileen O’Neill Burke implemented the Federal Immigration Enforcement Action Response Protocol — procedures for criminally prosecuting ICE agents who use excessive force. Developed after the Minneapolis ICE shootings.

This may be the most aggressive local government response to federal immigration enforcement in the country.

Courthouse Targeting

At least 5 ICE incidents at Cook County courthouses (Mar-Apr 2026), including the Domestic Violence Courthouse. This violates both a chief judge’s order and the state’s courthouse protection law. The Trump admin filed a lawsuit (Dec 29, 2025) to invalidate the law while ICE agents violate it in practice.

Broadview 6: Political Prosecutions

Six activists indicted on federal felony conspiracy charges for surrounding an ICE vehicle during a Sept 26, 2025 protest. Of 50-100 protesters, only Democratic officeholders and activists were charged. Two charges dismissed (March 2026); four still fighting. ICE agent texted about being “famous among lefties.”

Displacement Effect: Detention Without Facilities

Because Illinois blocks county detention, ICE transfers arrestees to:

  • Clay County Justice Center, Indiana
  • Dodge County Jail, Wisconsin
  • Hotels near O’Hare Airport

Illinois’s ban doesn’t stop detention — it displaces it across state lines to jurisdictions with fewer protections.

Legislative Response

HB 5024 (passed House Apr 8-9, 2026): Prohibits new federal detention centers within 1,500 feet of homes, schools, day care, parks, cemeteries, or places of worship. Wouldn’t close Broadview but would block new siting.

Budget-Distressed Counties Blocked from Cooperating

  • Kankakee County: Lost ~$6.5M/year in ICE bed fees (Jerome Combs Detention Center). FY2026 budget required “serious belt-tightening.”
  • McHenry County: Lost ~$10M/year ICE contract. Sheriff publicly stated state law hinders ICE cooperation.

These represent the “would cooperate if they could” category — political pressure to repeal the Way Forward Act.

Key Heatmap Implications

Cook County should score very high — not for cooperation signals, but for federal enforcement intensity against sanctuary protections. The Broadview pattern (processing center → de facto prison) is a variant of the warehouse conversion pipeline that bypasses state law entirely.
