Court filings reveal DHS conducted sweeping covert surveillance across Minnesota during last winter’s immigration enforcement surge, according to NPR. The operation included: undercover agents attending community meetings at churches, libraries, breweries, and schools; license plates captured outside a Roseville Lutheran church used to compile dossiers on churchgoers’ names, addresses, and family and job information; subpoenas of financial records from labor unions including SEIU and the Communications Workers of America; and at a public library meeting, an agent who allegedly identified himself as a construction worker and indicated he ‘didn’t mind going to jail’ — an apparent attempt to encourage illegal activity.
THE WIRE IN THE CHURCH
At Minneapolis’s University Baptist Church, pastor Cody Sanders learned an undercover DHS agent had worn a wire into a self-defense class held at the church in May. The class was offered as community support during the immigration enforcement surge. Pastor Sanders’ characterization: ‘It feels like 1950s Eastern Europe.’
ONYX covers this specific detail at its full weight. Churches have specific constitutional protections: the First Amendment’s Free Exercise Clause protects religious practice; the Fourth Amendment’s warrant requirements apply to intrusions into spaces with a reasonable expectation of privacy. A self-defense class hosted at a church for community members during an immigration enforcement surge is not an obvious federal criminal conspiracy. Sending an undercover agent wearing a recording device into that class is a specific law enforcement choice with specific constitutional implications.
THE LICENSE PLATE SURVEILLANCE
Capturing license plates outside the Roseville Lutheran church and using them to compile dossiers on churchgoers — their names, home addresses, and family and job information — is a specific surveillance methodology that ONYX documented in the Flock ALPR context on August 22 Section A Story 1. The difference here is intentionality: the Flock cameras capture all plates passing a given location; the DHS operation specifically targeted a church parking lot to identify its congregation.
The specific privacy violation: church attendance is protected religious practice under the First Amendment. Building a government database of who attends a specific church — with their home addresses and employment information — creates a state record of religious participation that the First Amendment specifically sought to prevent. The government has no established legitimate law enforcement reason to know who attends a Lutheran church based on their license plates.
THE UNION FINANCIAL RECORDS
DHS subpoenas of financial records from SEIU (Service Employees International Union) and the Communications Workers of America represent a distinct category of surveillance: labor union financial records. Unions are legally entitled to engage in political advocacy, organize workers, and support community causes — including providing legal support to immigrant workers. A criminal investigation that uses broad subpoenas of union financial records as part of a nominally narrow immigration enforcement case raises the question FIRE’s Aaron Terr named specifically: whether the government is investigating crimes or investigating political movements.
THE AGENT’S LIBRARY STATEMENT
At a public library meeting — a public space that carries specific expectations of free inquiry and open community gathering — an undercover DHS agent allegedly identified himself as a construction worker and indicated he ‘didn’t mind going to jail.’ If accurately characterized, this is an attempt at entrapment: a government agent presenting himself as sympathetic to illegal activity in order to encourage others to commit it. Entrapment — inducing someone to commit a crime they would not otherwise commit — is an established criminal defense; if this characterization is accurate, it raises specific legal questions about the investigation’s validity.
THE CIVIL LIBERTIES EXPERT ASSESSMENT
Two specific institutional assessments from NPR’s reporting:
▸ FIRE’s Aaron Terr: the revelations ‘raise the question of whether the government is investigating crimes or investigating political movements’
▸ Brennan Center’s Rachel Levinson-Waldman: the tactics ‘seem to break from decades-long norms and guidelines’ even if not clearly illegal
The distinction between ‘not clearly illegal’ and ‘constitutional’ is important. Many surveillance tactics that do not clearly violate specific statutory rules may still violate the broader constitutional framework. The relevant legal standards: the First Amendment prohibits government action that chills free exercise of religion and free association; the Fourth Amendment requires probable cause and warrants for intrusions into private spaces; and long-standing FBI and DOJ guidelines — which were developed after COINTELPRO’s abuses — impose specific limits on investigations of constitutionally protected activities.
“It feels like 1950s Eastern Europe.”

THE COINTELPRO HISTORICAL PARALLEL
The Brennan Center’s reference to ‘decades-long norms and guidelines’ is a specific reference to the post-COINTELPRO surveillance reform era. COINTELPRO (Counter Intelligence Program, 1956-1971) was the FBI’s covert operation against political organizations deemed ‘subversive’ by J. Edgar Hoover, including the NAACP, the Southern Christian Leadership Conference, the American Indian Movement, and socialist organizations. When COINTELPRO was exposed by the 1971 break-in at the FBI’s Media, Pennsylvania field office, the resulting public outrage produced the Church Committee hearings (1975) and the Levi Guidelines, which established specific limits on domestic intelligence investigations of constitutionally protected activities.
The Levi Guidelines and their successors — the Mukasey Guidelines (2008), the Smith Guidelines — specifically prohibit opening investigations of groups or individuals based solely on First Amendment activities (attending a church, joining a union, speaking at a public meeting). DHS operations in Minnesota may be within the letter of current guidelines or may not be; the Brennan Center’s characterization suggests they are at minimum at the boundary.
THE GOVERNMENT’S STATED JUSTIFICATION
Prosecutors have defended the surveillance as ‘within the authority’ of DHS during its immigration enforcement operation. The specific legal claim is that the surveillance was conducted in connection with a criminal investigation of an ICE-protest conspiracy case — not as general political monitoring. Whether the broad scope of the surveillance — church dossiers, union financial records, library entrapment attempts — is proportionate to a narrow criminal case is the specific legal question that civil liberties advocates and defense attorneys will litigate.
WHAT HAPPENS NEXT
▸ Court proceedings — the criminal case connected to the ICE-protest will produce additional disclosures of the surveillance scope
▸ Congressional oversight — the specific surveillance of churches and unions is material for Senate and House Judiciary Committee investigation
▸ Civil litigation — the churches, unions, and individuals surveilled may have standing for civil rights lawsuits
▸ Agency guideline review — whether DHS’s internal guidelines are adequate for the specific tactics revealed
▸ Additional surveillance disclosures — Minnesota may be one documented instance of a broader national pattern
| CONFIDENCE: HIGH | Court filings revealing DHS surveillance scope (church meetings, library, breweries, schools), license plate dossiers at Roseville Lutheran, wire at University Baptist Church, Cody Sanders quote, union subpoenas (SEIU, CWA), library agent statement, FIRE/Brennan Center expert quotes are all from NPR confirmed reporting. Historical COINTELPRO and Levi Guidelines context is from established public record. |
| ⚖️ BIAS CHECK — WHO IS SAYING WHAT | |
| DHS / DOJ | Characterizing the surveillance as within legal authority and connected to a specific criminal case; the narrow framing is the specific institutional defense |
| Pastor Cody Sanders | Has direct personal knowledge of the agent in his church; his characterization comes from the specific experience of learning his congregation was surveilled |
| SEIU / CWA | Organizations whose financial records were subpoenaed in connection with an immigration enforcement case; labor organization financial records are constitutionally sensitive |
| FIRE (Aaron Terr) | A civil liberties organization that defends free expression across the political spectrum; its concern about political movement investigation is consistent with its institutional mission |
| Brennan Center (Levinson-Waldman) | A liberal legal think tank with specific expertise in surveillance law; its characterization of guidelines being broken is based on expertise |
| ONYX | Covering the specific facts from court filings without editorializing beyond the documented expert assessments; the historical COINTELPRO parallel is named from established public record |

Q: Is it legal for federal agents to attend public meetings undercover?
A: Generally yes, attending a public meeting at a library or community space without a warrant is legal, as there is no reasonable expectation of privacy in a genuinely public meeting. However, wearing a recording device introduces additional legal questions depending on state law (Minnesota is a one-party consent state for recordings, meaning one party to a conversation can record without the other’s consent). The church class raises different questions because it was held in a semi-private space for specific community members, not a general public event.
Q: What are the Levi Guidelines?
A: The Levi Guidelines were established in 1976 by Attorney General Edward Levi following Congressional and public exposure of COINTELPRO and other domestic intelligence abuses. They specifically restricted the FBI from opening investigations of organizations or individuals based solely on First Amendment activities. The guidelines were subsequently modified by multiple administrations; the current standard (under the Mukasey Guidelines) requires “reasonable indication” that a crime has occurred or is about to occur before opening a domestic investigation.
Q: Why do union financial records matter?
A: Unions’ financial records document their political donations, organizing activities, legal support funds, and member assistance. A subpoena of union financial records in connection with an immigration enforcement case could reveal: which workers the union provided legal support to, which community organizations it funded, and which advocacy activities it financed. This information could be used to identify union members involved in immigration activism — a use that would raise First Amendment concerns about government compelled disclosure of protected association.
