Automated license plate readers are not simply a neutral “public safety tool.” They are a mass surveillance network that photographs every vehicle that passes, logs the plate, make, model, color, dents, stickers, and more, then stores it in a searchable cloud database that government agencies can query at will.

There's no warrant, no individualized suspicion, and no consent. That is the definition of a search of your “effects” under the Fourth Amendment.

This constitutional violation is an unreasonable search because it is general, continuous, and without probable cause. In addition, there are legitimate concerns that the cameras are not merely tracking license plates but may also be used for facial recognition to track the movements of individuals not in vehicles.

The Tulsa Numbers Don’t Hold Up

Recently a pro-Flock social media influencer, who appears to be paid to promote Flock and data centers, used an Oklahoma-specific example to advocate for more Flock cameras. Pro-Flock advocates frequently cite Tulsa’s 100% murder clearance rate in 2024, with a member of the police force stating that a high percentage of cases were attributable to Flock. Here is the actual record:

• Tulsa has maintained homicide clearance rates of 90–95%+ for years, well above the national average, long before Flock cameras were installed in 2022.
• The rate was also 100% in 2018—before Flock existed in the city.
• In 2016, a record-high year for murders, the clearance rate remained very high (reported in the mid-90s range by year’s end).
• Surrounding years with Flock in place have continued in the same high historical range (typically mid-90s when not at 100%).

High clearance rates long predate these cameras. Focusing on a single year of 100% and attributing it primarily to Flock is misleading, especially when the department’s own long-term performance shows the outcome is not new. Pretending a technology that does not materially change an already strong historical outcome justifies tracking every innocent driver is poor reasoning that treats the Constitution as optional.

Sources documenting the pre-Flock high clearance rates and the 2018 100% figure include investigative reporting by The Frontier drawing on FBI data.

Oklahoma’s Origin Story: Revenue First

Oklahoma did not adopt ALPRs primarily to solve murders. District attorneys and the District Attorneys Council pushed them under the Uninsured Vehicle Enforcement Program. The pitch to the legislature was straightforward: use these cameras to generate citation and diversion fees from uninsured motorists so offices could operate closer to “no cost” to the state budget and require less general-revenue funding.

It was a revenue play sold as insurance enforcement. The statute limited the purpose. In practice the technology expanded into general investigative use—the exact mission creep anyone familiar with government programs would expect. The constitutional cost is paid by every lawful driver whose movements are catalogued so prosecutors can pursue fee revenue.

Fourth Amendment Breakdown

The Fourth Amendment is not optional. It protects the right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures. No warrants shall issue but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the persons or things to be seized.

• A vehicle is an effect. Systematically photographing every one, capturing identifying features, and loading them into a government-accessible database is a search of that effect.
• No warrant is issued. There is no oath, no particularity, and no probable-cause determination by a neutral magistrate. Collection is continuous and casts a dragnet over every innocent person.
• The search is unreasonable because it is general, not particularized. It sweeps up the movements of the innocent majority so the government can later query the data.
• Retention and inter-agency sharing turn temporary observations into a rolling historical record of where free citizens go. That is a seizure of information without due process.

The Phone in Your Pocket Excuse Is Irrelevant

Pro-Flock advocates often claim, “You already have a phone in your pocket that tracks you everywhere.”

A phone is voluntary. You buy it. You carry it. You can leave it at home, turn it off, or place it in a Faraday bag. It is opt-in. You can refuse the technology entirely and still drive, work, and worship without the government compiling a searchable map of your life. But Flock is the opposite. No one opted in. No one consented to be tracked by it. You cannot leave the camera at home. You cannot opt out while still using the public roads. That is compulsion.

The “private company” distinction is constitutionally irrelevant. Flock is a private vendor. So what? The Fourth Amendment constrains government action. When law enforcement queries the database without a warrant, the government is conducting the search. There is no constitutional loophole that says the right to be secure in your effects disappears if the cameras are owned by a contractor. The government is still obtaining the data without a warrant, and that violates the Fourth Amendment.

Recent Failures Prove the Point

This is not theoretical. In recent months the failures have mounted:

• An LAPD inspector general audit found roughly one in three hot-list alerts generated by the system were false positives. Subsequent investigation confirmed the vehicles were not stolen. The department allowed its Flock contract to expire.‍
• The Washington Post documented nearly 50 cases of officers accused of or charged with misusing Flock data, the majority involving stalking current or former romantic partners, their new partners, or family members. Officers searched plates dozens or hundreds of times for personal reasons. Some were fired. Some were charged.
• In Wisconsin, a woman was pulled over at gunpoint after a Flock alert flagged her vehicle as linked to a homicide—because an employee had failed to remove an outdated wanted-vehicle entry. She was released, but only after an armed stop.

These are not edge cases. They are the predictable result of building a nationwide surveillance database and handing it to government actors with minimal real-time oversight. Shortened default retention periods and added login prompts are after-the-fact damage control, not a cure for the constitutional defect.

COVID Lockdowns Revealed Exactly How This Could Be Abused

In April 2020, Kentucky Governor Andy Beshear announced that state police would record the license plates of people attending in-person Easter services and other mass gatherings. Local health officials would then order those associated with the vehicles to self-quarantine for 14 days. Troopers went to church parking lots, wrote down plates, and left notices. Some people covered their tags; troopers recorded VIN numbers instead. Beshear called it the only way to ensure “your decision doesn’t kill someone else.”

This violation was manual, limited, and labor-intensive. Imagine the same policy with a Flock network already live. Every vehicle approaching or leaving a church, a protest, a political rally, or any gathering could be automatically logged, timestamped, and cross-referenced in seconds. No need to send troopers. Just query the system, generate the list, and issue the orders. The same architecture sold today as crime-fighting would have given government the ability to track and compel the isolation of citizens for exercising First Amendment rights—without individualized suspicion and without a warrant.

Conclusion

Flock cameras are incompatible with the Constitution. They search "effects" without warrants, without particularity, and without consent. The clearance-rate claims do not hold up under historical scrutiny. The phone comparison is false. The private-company excuse is a constitutional dodge. Documented false positives and misuse cases demonstrate the predictable risks of abuse. The COVID-era precedent shows how readily these tools can be turned against peaceful assembly and worship. As government power expands, the rights and liberties of the people contract.

Hard no. No exceptions. No “but the stats.” No “but the phones.” The Fourth Amendment is not a suggestion.
