Policy and law
Celina's policy includes real safeguards, but the system still creates searchable records about ordinary travel before suspicion exists. The stronger local choice is to end the program.
Why policy is not enough
This project does not allege that every search is improper. It argues that even compliant use leaves Celina operating a large, searchable, shareable record of vehicle movements.

Published purposes include electronic surveillance and homeland security without narrow definitions in the public policy. Policy source
The policy says reads go to Texas DPS every 24 hours. Flock's agency-sharing network is a separate route. Policy Portal
Celina publishes a total search count but not the search-level audit that would let residents examine when, why, and across how large a network searches were run.
Stronger rules could reduce some risks, but they would not stop routine collection. That is why this site supports ending the program.
Email City CouncilTexas DPS transfer
Celina's policy says the department sends reads to DPS every 24 hours and says DPS keeps them for 30 days. The standard DPS agreement says contributed data is kept for at least three years unless the user agency requests a shorter period.
That standard form also allows DPS to share contributed data with authorized criminal justice and law-enforcement agencies. Celina's signed agreement and any request for shorter retention have not been published, so the exact terms in force are still unverified. Celina policy Standard DPS agreement
Public audit comparison
Official record Celina's policy requires every detection-browsing inquiry to include a case or call number and/or a reason. The policy says individual credentials make use fully auditable, and the City's technology page says access is logged indefinitely. Yet Celina's portal displays only the total number of searches—not a query-level public log. Celina policy City technology page Celina portal
Inference Multiple Texas agencies use the same Flock portal platform to publish a downloadable 30-day Public Search Audit, including Temple, Pflugerville, and Denton. Arvada remains one detailed example: its file masks user IDs while showing timestamps, network counts, and offense types. These are public audit exports, not unredacted personnel logs. The comparisons establish that the platform supports search-level disclosure; they do not establish why Celina omits it. Temple example Pflugerville example Denton example Arvada example

Legal context
As of August 2, 2026, the research did not identify a comprehensive Texas law specifically setting warrant, retention, audit, and sharing rules for law-enforcement ALPR systems. HB 961 and HB 2083 proposed protections but did not become law. HB 961 text HB 961 history HB 2083 text HB 2083 history
Texas's general consumer privacy statute exempts state agencies and political subdivisions, so it is not a substitute for a municipal ALPR ordinance. Texas Business and Commerce Code Chapter 541
The Texas Public Information Act generally reaches existing city records, while law-enforcement, motor-vehicle, privacy, security, and other exceptions may allow or require withholding or redaction. A request should ask for records, not require the city to create a new report or answer questions. Texas Government Code Chapter 552 Attorney General guidance Celina request guidance
In United States v. Porter, decided March 17, 2026, the Fifth Circuit held that the periodic public-road LPR observations at issue were not a Fourth Amendment search. The case involved a local network of no more than ten cameras. It does not necessarily resolve every denser, longer-term, or multi-jurisdictional tracking scenario. Fifth Circuit opinion
Current Fifth Circuit precedent permits the limited LPR use considered in Porter without a warrant. Broader networked tracking may raise different legal questions, and Celina can adopt protections stronger than the constitutional minimum.
The U.S. Supreme Court treated long-term historical cell-site location records as a search in Carpenter v. United States. That case concerned cell-site data, not automated license plate readers. U.S. Supreme Court opinion
Do not overread the law. The sources do not establish that ALPRs are categorically constitutional or unconstitutional, and proposed bills are not enacted safeguards. A constitutional minimum is also not a command to operate this program: Celina's elected officials can choose not to collect.
The local policy choice
Ask Council to review the program in public, disclose the missing local outcomes, and move toward ending collection and removing all 47 readers.
