If you live in Central Texas, you’ve probably seen the small gray FLOCK license plate cameras popping up around New Braunfels, San Marcos, Austin and the surrounding areas. Alongside them, there’s been a lot of misinformation — claims that these cameras are spying on your every move, recording your face, or “tracking innocent people for no reason.”

Let’s cut through the noise and talk about what the law actually says and what the numbers actually show.

1. What the Supreme Court Says About License Plates & Privacy

For decades, the U.S. Supreme Court has been very clear on one key point:

You do not have a reasonable expectation of privacy in things you expose to the public.

That comes from Katz v. United States, where the Court explained that “what a person knowingly exposes to the public… is not a subject of Fourth Amendment protection.” Department of Justice

Your license plate is required by law to be displayed openly on a public roadway. Because of that, courts have consistently ruled that:

• There is no reasonable expectation of privacy in the information on your license plate when you’re driving on public roads. Department of Justice+2CaseLaw+2

• Police are allowed to visually observe or run your plate in a database, even without separate “probable cause,” because that is not considered a “search” in the constitutional sense. LLRMI+1

A few key cases to understand this:

• New York v. Class (1986) – The Supreme Court held that there is no reasonable expectation of privacy in a Vehicle Identification Number (VIN) that’s meant to be visible from outside the car. The Court emphasized that because of vehicle regulation, certain identifiers must be placed in plain view, so there is no privacy interest in them. Justia Law+2Library of Congress Tile+2

• Kansas v. Glover (2020) – The Supreme Court ruled that an officer can run a plate, see that the registered owner’s license is revoked, and make a traffic stop based on the reasonable inference that the owner is driving—without any extra evidence. Justia Law+2Wikipedia+2

Legal scholarship summarizing these decisions notes that, because of the “pervasive regulation of vehicles”, there is no expectation of privacy in the content of license plates. Brennan Center for Justice+1

Bottom line:
Seeing, photographing, or electronically reading a plate that’s already visible to every driver around you is not a constitutional violation.

2. What FLOCK Cameras Actually Do (and Don’t Do)

There’s a lot of wild claims online, so here’s the reality of standard  ALPR systems:

What they DO:

• Take still images of vehicles and license plates on public roads, along with the date, time, and location. Flock Safety+1

• Capture vehicle details (make, model, color, roof rack, etc.) as “vehicle fingerprints” to help investigators identify suspect vehicles. Flock Safety+1

• Compare plates to hotlists (stolen vehicles, wanted violent offenders, AMBER/Silver Alerts, missing persons, etc.) and send real-time alerts to some law enforcement. Flock Safety+2Flock Safety+2

What they DO NOT do (by design):

• ❌ No facial recognition. FLOCK states plainly that their ALPR system does not use facial recognition and cannot be used to search for human characteristics like race or gender. There are other systems utilized for this.Fair Oaks Ranch+3Flock Safety+3Flock Safety+3

• ❌ Not traffic-enforcement / speed cameras. FLOCK cameras are not used to issue speeding tickets and do not capture speed data; they are focused on vehicles tied to crime, not everyday traffic violations. Leander TX+2Flock Safety+2

• ❌ Not permanent surveillance storage. FLOCK’s default policy is that data is retained for about 30 days and then automatically deleted, unless it’s preserved as evidence in an active case. There are other systems available who store for much longer lengths of time, based on state regulations.Flock Safety+3Flock Safety+3Fair Oaks Ranch+3

So the idea that these cameras are “building lifetime files on every person" is simply not accurate under the way the system is designed and marketed.

3. Why Vehicles Matter: The Role of Cars in Crime

This is the part most people never see in Facebook arguments:

• Law enforcement and city transparency reports regularly note that around 70% of crimes involve a vehicle in some way — either used in the crime, arriving/leaving the scene, or transporting stolen property or suspects. Brimfield Township+2Leander TX+2

If you can quickly identify and locate that vehicle, you can:

• Recover stolen vehicles

• Catch violent offenders while they’re still mobile

• Intercept heinous fugitives

• Find missing and abducted kids faster

That’s where ALPR technology, including FLOCK cameras, plays a critical role.

4. The Results: Stolen Cars, Violent Fugitives, and Missing Kids

Across the U.S., FLOCK’s network is now in thousands of communities. The company’s own impact studies and multiple city reports show:

• FLOCK estimates that over 700,000 crimes each year are now solved using their technology — roughly 10% of all reported crime nationwide. Flock Safety+2Flock Safety+2

• FLOCK technology has helped law enforcement agencies find and reunite more than 1,000 missing people with their families. Flock Safety

• Through a partnership with the National Center for Missing & Exploited Children, FLOCK-enabled AMBER Alerts have helped solve over 100 missing child cases since 2021. Flock Safety+2houstontx.gov+2

• In specific cities, police departments are reporting major reductions in vehicle crime. For example, Boulder, Colorado saw a 34.5% reduction in motor vehicle thefts after implementing FLOCK cameras, along with solved hit-and-runs and violent attacks. City of Boulder+2Police Chief Magazine+2

These aren’t theoretical numbers. They represent real stolen vehicles recovered and real violent suspects taken off the street by using license plates as leads — not guessing, not profiling.

5. What This Means for Central Texas

Here in the Hill Country:

• FLOCK cameras are being used to identify stolen vehicles, locate wanted fugitives, and support investigations into serious crimes — not to harass random drivers or track your everyday movements. Leander TX+3Atlas of Surveillance+3Facebook+3

• They give law enforcement objective, vehicle-based evidence, which can actually reduce bias because the system flags plates tied to criminal activity. Flock Safety+2Brimfield Township+2

• When a child goes missing, when a violent felon is on the run, or when a car is carjacked at gunpoint, having cameras already in place across major routes can be the difference between “we have no leads” and “we arrested them or rescued your child within hours.” Flock Safety+2Flock Safety+2

If you’ve ever shared a post about a missing child, a hit-and-run, or a wanted suspect in our area, this is the same idea — just with technology doing the “be on the lookout” work 24/7.

6. Honest Talk About Privacy & Oversight

It’s also true that some cities around the country have raised real, legitimate concerns about how ALPR data is used and shared:

• In Austin, city officials paused an extended FLOCK program amid questions about data sharing and oversight. Statesman

• Some jurisdictions have temporarily suspended their FLOCK pilots while they reassess privacy protections and federal data access. KOMO+2AP News+2

Those debates are important. They’re exactly why we need:

• Clear written policies about who can search the system and why *

• Short data-retention periods (weeks or months, not years) *

• Audit trails for every search )

  * Most agencies already have this implemented

Supporters of the cameras in Central Texas are not saying, “trust government blindly.” We’re saying:

Use the tools, but back them up with strong policy, transparency, and accountability.

7. The Takeaway

You can disagree about where the line should be drawn — that’s healthy. But the facts matter:

• License plates on public roads are not private under long-standing Supreme Court and appellate case law. This isn't in question. It has been the long-standing opinion of the highest court in the country.

• FLOCK cameras do not use facial recognition, do not track race/gender, and are not traffic ticket cameras. Flock Safety+3Flock Safety+3Flock Safety+3

• They are helping law enforcement recover stolen vehicles, catch violent offenders, and find missing children and adults across the country — including right here in the Hill Country. Flock Safety+4Flock Safety+4Flock Safety+4

People willfully or ignorantly provide consent to tech companies, such as: Google, Apple, Samsung, Facebook, X, Instagram, as well as numerous apps to collect FAR more personal and private data which is sold to the highest bidder for marketing and sales purposes, yet have a problem with companies like FLOCK who are providing a service specifically to law enforcement and other investigative entities to prevent crime, save lives, and serve justice.  This data isn't collected and sold to highest bidders for marketing and inaccessible to the general public at large. 

If you’ve got questions or concerns, ask them. Go to public meetings, read your local department’s FLOCK policy, and look at the actual data. But don’t let Facebook rumors drown out the very real stories of victims who got justice – and families who got their loved ones back – because a license plate camera saw what a human being would have seen anyway. I urge you to talk to professionals who use these systems on a daily-basis and get a true understanding of how they're used, how they work, and where they make life safer.
