What happened
In an Oct. 23, 2026 letter to Acting ICE Director David Venturella, Reps. Pettersen and Krishnamoorthi and 33 other House Democrats cite reporting that ICE has used state and local law-enforcement agencies to run more than 4,000 searches of Flock ALPR data on its behalf, with no formal contract or governing agreement. They ask, by Nov. 20, 2026: how often ICE obtained Flock data directly or through partners; for what purpose; how many people were detained, arrested or subjected to enforcement as a result; under what legal authority; whether ICE has a policy on ALPR data obtained indirectly; whether it has done a legal review under federal privacy law, the Fourth Amendment or DHS policy; and whether it plans a contract or MOU with Flock or another vendor. The 4,000 figure comes from press reporting cited in the letter, not from the members’ own audit.
Why it matters
Puts the downstream use of local ALPR data at the federal level: local agencies that run searches for federal partners are the access route the letter describes, which makes local sharing policy and audit logs the practical control.
Evidence and measured results
Opened the signed letter PDF on pettersen.house.gov and read it in full; also opened Rep. Krishnamoorthi’s press release of the same date for context.
Limitations and uncertainty
A letter of inquiry, not findings; the 4,000-search figure is from press reporting the letter cites; no ICE response yet. Partisan signatories (all Democrats). Does not evaluate any specific agency’s practices.
Put this evidence to work
Lighthouse Advisory interpretation, grounded in this source. Enriched 2026-10-26; this does not change the original publication date. Each role follows the same checklist so takeaways compare across sources.
Sales
Role takeaway
- Customer problem
- Local agencies may be the route through which federal immigration authorities reach ALPR data, without a contract that sets terms.
- Stakeholders
- Police chiefs and sheriffs
- City and county attorneys
- Councils and oversight boards
- State privacy regulators
- ALPR vendors
- Discovery questions
- Do your officers run plate searches at the request of federal agencies?
- Do search logs record the requesting agency and purpose?
- Does your contract or policy address searches run on behalf of others?
- Value hypothesis
- An audit of outside-agency searches could let an agency answer council and public questions with evidence.
- Potential engagement
- Outside-agency search audit for one ALPR program, ending in a sharing rule and a reporting template.
- Unsupported claims
- That any specific agency shared data unlawfully
- The accuracy of the 4,000-search figure
- What ICE will answer
Pre-sales engineering
Role takeaway
- Fit
- Agencies on networked ALPR platforms with national or cross-state lookup.
- Architecture and integration
- Per-search reason codes, requester fields and exportable audit logs on the vendor platform; integration with case management for case numbers.
- Prerequisites
- Audit log export
- Defined permissible purposes
- State sharing law review
- Constraints
- State laws differ on federal and out-of-state sharing
- Vendor platform controls log fields
- Federal response pending
- Security
- Require case numbers and requester identity per search; restrict national lookup; review logs for immigration-related terms.
- Proof of value
- Proposed: classify one quarter of searches by purpose and flag missing case numbers
- Proposed: confirm logs capture searches run for other agencies
Delivery
Role takeaway
- Work
- Audit outside-agency searches, write a rule on assisting other agencies, and publish periodic search statistics.
- Dependencies
- Vendor log access
- City attorney review of state law
- Records retention policy
- Ownership
- Police chief with the city attorney
- Skills and adoption
- Train officers on permissible search purposes and logging requirements.
- Governance checkpoints
- Council briefing on audit results
- Policy adoption
- Quarterly search reports
- Acceptance criteria
- Proposed: 100% of searches carry a case number and requester
- Proposed: quarterly public report of outside-agency searches
- Risks
- Incomplete or unavailable logs
- Escalation before ICE responds
- Officer non-compliance with logging
Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Access described is indirect: searches run by local accounts on a networked vendor platform, so controls depend on per-search reason codes and audit logs in each agency.
Governance
Who approves, reviews and stays accountable for outcomes?
Requests ICE’s legal authority, internal policy and legal review; responses due Nov. 20, 2026. The letter is a request and carries no compulsory force.
Security and privacy
What data, permissions and controls need testing?
Frames warrantless federal access to location data across states as a privacy and Fourth Amendment concern.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Limited relevance.
Procurement
What should contracts, pricing and exit terms secure?
Asks whether ICE intends to formalise a contract or MOU with Flock or another ALPR vendor; local contracts may need explicit terms on searches run for other agencies.
Operating model
Which teams own the service once it runs?
Local officers running searches for federal partners are the access point, so local policy on assisting other agencies becomes central.
