Illinois ICE says state released 1,768 criminal non‑citizens with active detainers, warns public safety at risk
Illinois ICE officials say 1,768 non‑citizens with criminal records and active federal detainers were released from state custody since January 2025 across the state, claiming Illinois’ non‑cooperation laws have undermined public safety and complicated federal enforcement.
- ICE’s tally: Federal officials say 1,768 people with criminal records and active detainers left Illinois custody in 2025, a figure provided by ICE and not independently verified.
- Legal limits: Illinois’ TRUST Act and Illinois Way Forward Act restrict holding people solely on civil ICE detainers and ended many local ICE contracts.
- Detainer nature: Detainers (Form I‑247) are civil requests — courts have found them voluntary, and holding someone solely on a detainer can create legal liability.
- Context: National detainer use and ICE detention rose sharply in 2025, shaping the broader enforcement debate and Illinois‑ICE dispute.
ICE’s claim and context
What ICE says: According to Illinois ICE officials, the agency’s internal accounting shows 1,768 cases in which a detainer was active but custody did not transfer to ICE before the person was released from state custody. ICE statements framed the number as evidence that Illinois’ non‑cooperation policies put public safety at risk; an ICE official (identified in ICE releases as Lyons) said offenders “should be swiftly removed from the United States and not be returned to our streets to wreak havoc on law‑abiding citizens.”
What an ICE “detainer” is — and why it matters
An ICE detainer (Form I‑247) is a civil request that typically asks local jails for two things:
- a notice before the individual’s release so ICE can attempt to assume custody;
- in many cases, an additional request to hold the person up to 48 extra hours so ICE can take custody.
Because detainers are civil rather than judicial warrants, courts have repeatedly found that local agencies are not compelled by federal law to comply. Holding someone only on a detainer — without a warrant or other lawful basis — can expose counties and states to lawsuits. For more detail, see the TRAC report on detainers and detainer law.
Illinois policies that limit cooperation with federal immigration enforcement
Two state laws shape Illinois practice:
- Illinois TRUST Act — generally prohibits detaining someone solely on the basis of an ICE detainer or administrative warrant and bars stops or arrests solely for immigration status.
- Illinois Way Forward Act (2021) — ended many ICE contracts with local jails and limits certain information‑sharing and joint operations with ICE.
Under those statutes, local jails and state prisons typically release people when state law or case dispositions require it. If ICE wishes to take custody, the agency must secure a judicial warrant or arrest the person after release, which is central to the state’s argument about constitutional protections and community policing.
Evaluating ICE’s 1,768 figure
Important context when assessing the number:
- The figure is from ICE’s internal accounting and has not been matched to a public, case‑by‑case dataset showing charges, convictions, removals, or subsequent arrests.
- ICE’s label of “criminal alien” can cover a wide range of conduct — from serious violent felonies to old convictions, misdemeanors, pending charges, or minor offenses.
- Analysts note that many detainers involve people with relatively minor records or no record at all; national detainer and detention totals rose substantially in 2025, providing broader context for the Illinois dispute. See the analysis of ICE detention growth in 2025 and the TRAC report on detainers and detainer law.
How “criminal” and “violent” are used — and why definitions matter
ICE statements commonly highlight the most serious examples among a larger group. When officials emphasize “violent criminals,” the public figure may still include many people with less serious records. Legal definitions vary and mixing felonies, misdemeanors, pending charges and old convictions in a single tally can overstate the sense of imminent violent danger. Journalists and policy analysts therefore treat ICE’s aggregate number as a starting point that requires deeper, case‑level data.
The legal and public‑safety debate
This issue sets two principles against each other:
- Federal enforcement priority: ICE argues detainers are needed to remove non‑citizens with criminal records before they return to communities.
- State/local constitutional and community policing priorities: Illinois and supporters say detainers alone are not lawful bases to hold people and that honoring them can chill cooperation between immigrant communities and local police.
Supporters of Illinois’ approach point to Fourth Amendment risks and the value of community trust; supporters of ICE emphasize immediate public safety and the administrative burden of locating people after release.
What can be verified — and what remains partisan
Verifiable facts:
- Detainers are civil requests, not judicial warrants; courts have repeatedly found them voluntary (see the TRAC report on detainers and detainer law).
- Illinois law curtails cooperation with ICE via the TRUST Act and Way Forward Act.
- ICE detention and detainer use rose substantially in 2025 (see the analysis of ICE detention growth in 2025).
Unverified or partisan claims: The precise breakdown of the 1,768 individuals — such as how many were convicted of violent felonies, how many faced only minor charges, and how many were later removed or re‑arrested — is not publicly available in a verified dataset tied to ICE’s total. That leaves the number as an agency claim used in public safety messaging.

Implications for Redding, California
Though this is an Illinois‑centered dispute, local officials and voters in places like Redding and Shasta County may face similar tradeoffs:
- Public safety and law enforcement cooperation: Local agencies must weigh whether to follow state and county policies limiting detainer cooperation; if they decline, federal agents may need to arrest people in the community, which can be disruptive and costly.
- Crime victims and community policing: Conservative residents may stress law and order and worry about repeat offenders; police chiefs warn communities may be less likely to report crimes if they fear immigration consequences.
- Resources and budgets: If ICE must locate and arrest people after release, federal enforcement absorbs more resources, and local agencies must prioritize scarce budgets.
- Political consequences: The Illinois example offers ammunition to both sides — those urging closer cooperation with ICE and those emphasizing legal risk and community trust.
“Holding someone solely on a detainer — without a judge’s warrant or other legal basis — can expose counties and states to lawsuits,” legal analysts note, underscoring why Illinois enacted limits on cooperation.
Bottom line: The tension between federal enforcement goals and state legal limits — and ICE’s public safety claims in Illinois — will continue to influence debates in other states and communities as leaders weigh safety, legal risk and community trust.
