Three Rivers Police Department Confirms Continued Use of Flock Surveillance Cameras as City Adds Eighth Camera
The Three Rivers Police Department (TRPD) confirmed on April 1 that its license plate reader technology is active and being used by the department to aid investigations, even as national civil liberties groups raise concerns about the system's capabilities.
How the Cameras Work
In Three Rivers, there are currently seven license plate reader cameras throughout the city. The cameras are motion-activated and capture an image when a vehicle passes, identifying the license plate, make and model.
The cameras are placed at locations intended to capture high volumes of traffic. Once a vehicle is recorded, the data is stored for up to 30 days and then removed unless it is preserved as part of a criminal investigation.
"I think it's far cheaper than seven cops posted up 24/7, on these intersections," said Detective Sgt. Steven Dibble. "You know, if we, if we've got minimum staffing and, you know, we're not out there on all of these locations and things like that, you know, you don't see what you don't see. So I think that's the biggest advantage to this system."
Department Policy on Camera Use
Three Rivers Chief of Police Scott Boling and Detective Sgt. Dibble said the cameras are limited in scope and do not record people or use facial recognition technology.
"It takes pictures of a vehicle when it passes, and not of people," Boling said. "It's just the back of a vehicle."
Boling said he does not believe the cameras violate Fourth Amendment protections because they capture images in public spaces.
"There's argument license plates are private information — well, it's not, it's meant to be seen," Boling said.
Dibble acknowledged privacy concerns but said surveillance is already common in daily life.
"I think privacy matters. I think privacy matters a lot to everybody," Dibble said. "I don't think I should have to be recorded, you know, shopping with my child at Meijer, but I am, because it's the cost of doing business."
National Controversy Over Flock Technology
Flock Safety's license plate reader system has drawn national criticism from civil liberties groups, particularly the American Civil Liberties Union (ACLU), which argues the technology enables a form of mass surveillance that extends beyond its original purpose.
In an August 2025 report, the ACLU warned that Flock is "building a dangerous nationwide mass-surveillance infrastructure" by allowing law enforcement agencies across the country to access and search a shared database of vehicle movements.
According to the report, records obtained by the tech outlet 404 Media show that some local police departments have used the system to conduct searches on behalf of U.S. Immigration and Customs Enforcement (ICE), including its Enforcement and Removal Operations division.
In April 2025, the website haveibeenflocked.com — which compiles public records of law enforcement searches using Flock — lists the Three Rivers Police Department as the searching agency in a query associated with an "NCIC ICE" warrant.
The report also cited a case in Texas in which a police officer used the system to search nationwide for a woman suspected of obtaining a self-managed abortion, raising concerns about how the technology could be used to track individuals across state lines.
Beyond specific cases, the ACLU warns that the system's capabilities are expanding. The organization points to efforts by Flock to integrate its data with commercial data brokers, which could allow law enforcement to connect license plate data to personal identities.
What TRPD Says About Data Sharing
Boling said there is no "backdoor access" to the system, including for federal agencies such as ICE, and that any data sharing must be approved by the department.
"No one has access to our cameras unless we approve it and vice versa," Dibble said. "It's not like just a blanket — we're sharing with everybody."
Police can request access to data from other agencies, but sharing is not automatic and must be approved by each agency.
"It has to be a crime and has to be a criminal complaint number for us to even consider looking at to identify a vehicle," Dibble said. "And obviously there's a vehicle involved, like, if they fled on foot, we're not looking at Flock because we do, we don't. We're not looking for people, we're looking for the vehicle that was used."
Dibble added that the system is not used for minor violations.
"We're not looking at vehicles because they illegally park downtown … we're not looking at it for minor traffic infractions," Dibble said.
History of the Program
The department began using the cameras in 2023 through a two-year federal grant from the U.S. Department of Justice's Rural Violent Crime Reduction Initiative (RVCRI), according to prior reporting by Watershed Voice.
Six cameras were installed throughout the city under that grant.
In 2025, after the grant expired, the city began paying $3,000 per camera annually. Also in 2025, the city added a seventh camera, bringing the total annual cost to about $21,000.
What's Next
While Three Rivers continues to use the system, the broader debate over law enforcement use of license plate reader technology continues across the country, with concerns about privacy, civil liberties, and the potential for expanded surveillance capabilities.
The city has not indicated whether it plans to add additional cameras or expand the system in the coming year.
