The Johnston Brief
If you've noticed the small solar-powered cameras on poles around town and wondered what they are, you're not alone. Johnston, like most of the Des Moines metro, uses automated license plate readers. Here's the plain-English rundown: what they do, what happens to the data, the national data-sharing fight that blew up in 2025 and 2026, where Iowa law actually stands, and the tools that let you check for yourself. No spin, both sides.
Yes. The Johnston Police Department uses Flock Safety automated license plate readers (ALPRs). The Johnston City Council approved an agreement with Flock Group Inc. for 11 solar-powered cameras in "strategic gateway areas," and they began operating in July 2024 under a three-year contract reported at $109,500. The cameras aren't traffic-enforcement devices: they don't measure speed or issue tickets. The hot-button issue right now is data-sharing: reporting in 2025 and 2026 found police nationwide searched these networks on behalf of federal immigration agents thousands of times. You can browse crowd-mapped camera locations on DeFlock, or view the department's program on its Flock transparency portal.
A Flock camera is an automated license plate reader, or ALPR. It's a small, often solar-powered camera mounted on a pole near a road. As vehicles pass, it photographs each license plate and logs basic descriptors: the make, color, and body type of the car, plus the date, time, and location. Software reads the plate and can send police an alert when a plate matches a "hotlist," such as a stolen vehicle, an AMBER or Silver Alert, or a plate tied to an active investigation.
The key distinction critics draw: unlike a red-light or speed camera, which only acts when someone breaks a law, an ALPR records every passing vehicle, whether or not the driver is suspected of anything.
The Johnston City Council approved an agreement with Flock Group Inc. for 11 solar-powered cameras, placed in what the city called "strategic gateway areas" to capture the rear license plates of vehicles on public roads. The cameras began operating in July 2024, under a three-year contract reported at $109,500, making Johnston one of the more recent Des Moines metro cities to adopt the technology. Police have pointed to real cases: officials said a suspect in an armed robbery in Johnston was linked, through the Flock network, to other robberies in Des Moines and Cedar Rapids, helping build probable cause for an arrest.
Most central-Iowa cities, Johnston included, contract with Flock Safety. The city of Des Moines is the notable exception: it uses Motorola license plate readers instead. Across the metro there were nearly 320 readers as of late 2025, spread across suburbs including Altoona, Ankeny, Clive, Johnston, Urbandale, Waukee, and West Des Moines.
Note: retention is Flock's standard 30-day setting, applied unless a department changes it. For Johnston's exact policy, the department's transparency portal is the source to check.
What turned Flock into national news was data-sharing: the debate stopped being about the camera on the pole and became about the database behind it and who can reach into it. For a few years these cameras were a quiet local-government line item, then the story changed.
Here's the thread, kept to what's actually been reported. Investigations in 2025 and 2026 by outlets including 404 Media, and by the Electronic Frontier Foundation and the ACLU, found that local and state police around the country searched Flock's shared network on behalf of federal agents. One widely cited figure: more than 4,000 searches tied to immigration reasons between mid-2024 and mid-2025, with officers sometimes typing "ICE" or "immigration" as the stated reason. Flock has said it doesn't sell data and that each community owns its own, but the company also confirmed it held pilot contracts with Customs and Border Protection and DHS that gave those agencies a form of access. In Illinois, an audit found out-of-state and federal agencies had reached into local Flock data, and California is now the subject of a class-action lawsuit over cross-state sharing.
After the backlash, Flock added an administrative switch that lets any agency turn off all federal sharing with a single toggle. Whether a given department has flipped it on or off is exactly the kind of thing a resident can now ask about. Some cities went further and walked away entirely: the LAPD began renegotiating its contract in mid-2026 over civil-liberties concerns, and a number of smaller cities cancelled outright.
Important local caveat, and we're holding to real facts here: we've seen no public reporting that any Des Moines metro department, Johnston included, has run immigration searches. The national story is real; a claim about our specific city would need its own evidence. The good news is you don't have to take anyone's word for it, because the usage logs are checkable. Here's how.
There are two public tools, one official and one citizen-built, and they're worth knowing about regardless of where you land on the issue.
Flock runs a public dashboard for each department showing program details and search activity, straight from the source. For Johnston, look for the department's Flock transparency portal at transparency.flocksafety.com/johnston-ia-pd →, and the City of Johnston site for its own program information. Look for the audit or usage section, which is where search counts and stated reasons show up.
DeFlock is a free, open-source project where volunteers plot ALPR camera locations onto a public map, Johnston included. Browse it at maps.deflock.org → and search your area. It won't be exhaustive, since it depends on people spotting and reporting cameras, but it's the best public map that exists.
If the transparency portal doesn't answer your question, Iowa gives residents a stronger tool: the state's open-records law, Chapter 22 of the Iowa Code. Any resident can request public records from a city department, and a Flock usage audit is a public record. You don't need a lawyer or a reason. Here's a straightforward way to do it.
That's the same path reporters used to surface the national numbers. It's civics, not conspiracy, and it works the same whether you love the cameras or want them gone.

This is a genuine, unsettled question. Here's the honest version of each side.
Departments say ALPRs help solve crimes faster: locating stolen vehicles, following up on active investigations, finding cars linked to missing or endangered people, and generating leads without a physical stakeout. Johnston police cited a case where the network tied a local robbery suspect to other robberies in Des Moines and Cedar Rapids. The cameras don't issue tickets and aren't used for traffic enforcement. They're an investigative tool, and local police point to real cases closed with them.
The ACLU of Iowa, in a December 2025 report with the University of Iowa's Graham Technology Law Clinic, argued that logging every passing car amounts to mass, warrantless surveillance and raises Fourth Amendment concerns. Their biggest worries are how long data is kept and, above all, data-sharing: contracts that can feed a local camera's readings into a nationwide database searchable by outside agencies, which is precisely the pipeline the 2025 and 2026 reporting exposed. They've called for warrant requirements, tighter retention limits, and hard restrictions on sharing. That debate is live locally too: Johnston has seen several of its cameras vandalized, echoing a broader national backlash.
As of now there is no statewide Iowa law specifically governing license plate readers, and it's an easy thing to get wrong. Lawmakers tried in 2026. House File 2161 would have required cities to pass an ordinance authorizing ALPR use, forced permanent deletion of images within 30 days, required a warrant to access data older than 24 hours, and mandated a usage log. It advanced through committee, but the House and Senate couldn't agree on final language, and the session adjourned without it passing. So the rules still vary city to city, which is exactly why the transparency portals and open-records requests above carry the weight.
Yes. The Johnston Police Department uses Flock Safety automated license plate readers (ALPRs). The Johnston City Council approved an agreement with Flock Group Inc. for 11 solar-powered cameras placed in strategic gateway areas, and they began operating in July 2024. Johnston is one of several Des Moines metro suburbs in a Flock network that totaled nearly 320 readers across the metro as of late 2025.
The Johnston City Council approved 11 solar-powered Flock cameras, placed at strategic gateway areas around the city, under a three-year contract reported at $109,500. Johnston officials indicated the program could grow. Because the count can change, the department's Flock transparency portal is the best place to confirm the current number.
Flock Safety ALPRs are cameras mounted near roads that photograph the license plate and basic details (make, color, type) of every passing vehicle. Software converts the plate to text and can alert police when a plate matches one tied to an active investigation, a stolen vehicle, or a missing-person alert.
No. Flock cameras are not traffic-enforcement devices. According to the program's description, they do not measure speed, do not capture red-light violations, and do not record people running crosswalks or passing stopped school buses. They read license plates as an investigative tool and do not issue citations.
That is the central 2025-2026 controversy. Reporting found local and state police nationwide ran more than 4,000 Flock searches for immigration reasons between mid-2024 and mid-2025, often on behalf of ICE, and Flock confirmed it had held pilot contracts with Customs and Border Protection and DHS. In January 2026 Flock added a setting that lets an agency switch off all federal sharing. Whether any Des Moines metro department, Johnston included, has run such searches is something a resident can check through the department's transparency portal or an open-records request.
Yes, ALPRs are currently legal and in use in dozens of Iowa communities. There is no statewide law governing them: a 2026 bill, House File 2161, would have required local ordinances, a 30-day deletion rule, and a warrant to access data older than 24 hours, but it did not pass before the legislature adjourned. The ACLU of Iowa continues to raise Fourth Amendment and data-sharing concerns.
The best public tool is DeFlock (maps.deflock.org), a free volunteer-built map where you can search your area and see plotted ALPR camera locations. It is not exhaustive, since it depends on people reporting cameras, but it covers Johnston and the wider Des Moines metro. For the official program details of a specific department, use that city's Flock transparency portal.
