A standing-room-only crowd packed the Caldwell City Council chambers on July 6, with attendees spilling into hallways and out the door — a turnout that reflected growing public unease over automated license plate reader technology deployed by police departments across Idaho.

The gathering centered on the Caldwell Police Department’s use of Flock Safety automated license plate readers, or ALPRs, which use artificial intelligence to continuously scan vehicle plates passing camera locations. As of July 2026, most major cities in Idaho have signed contracts with the Georgia-based company.

How the Technology Works

Police departments interact with Flock’s system in two primary ways. The first is a detection function, where officers receive automatic alerts when a vehicle on a watchlist passes any camera in the network. The second is a lookup function, in which officers manually search the system for a specific plate.

Audit records from the Ada County Sheriff’s Office show that officers have searched plates associated with categories including drug offenses and trespassing, indicating the technology extends beyond violent crime investigations.

Twin Falls Police Lieutenant Steven Gassert, of the Administrative Services Division, described the practical appeal of the system to the Idaho Capital Sun. “You have your old school cop way of going and knocking on every door and talking to every homeowner to see if they have camera footage. That can be pretty cumbersome for two or three detectives, to go out and contact 30 or 40 different homes or businesses,” Gassert said. With ALPR access, he added, officers “can access data rather quickly, eliminating the need to go door-to-door for hours on end.”

A late 2023 Twin Falls case illustrated the network effect. A suspect with a reported $1 million outstanding warrant from California was flagged by local Flock cameras, prompting Twin Falls officers to alert surrounding agencies, who ultimately made the arrest.

Deployment Numbers Across Idaho

The scale of Flock deployment varies considerably by city. Twin Falls leads the state with 40 cameras under a contract worth at least $43,800 annually. Pocatello operates 36 cameras on a contract of at least $10,000 per year, while Idaho Falls runs 20 cameras at a cost of at least $40,200 annually. Caldwell, where the public pushback has been most vocal, has at least 10 cameras under a contract of roughly $30,000 per year, based on 2025 city documents.

Flock’s own 2025 “Impact Census” claimed that in communities where the system is deployed, roughly one in five criminal cases resolved involved ALPR data at some point in the investigation. Critics note that figure comes from the company itself.

Legal Challenges and Civil Liberties Concerns

A group called DeFlock Idaho has filed tort claims against both Caldwell and Wilder over alleged violations related to ALPR use, signaling that the debate may soon move from city council chambers into courtrooms.

Civil liberties advocates argue the technology’s reach extends well beyond targeted suspects. Saira Hussain, a senior staff attorney with the Electronic Frontier Foundation, told the Idaho Capital Sun that the core problem is the scope of data collection. “99% of people who are driving around are never pinged on any sort of hotlist, but their information can still be searched,” Hussain said. “It is a mass surveillance technology that is being used without a warrant or without suspicion, but it casts a wide net over everybody in the driving public.”

Legislative History and What Comes Next

Idaho lawmakers addressed the issue during the 2025 session when Senate Bill 1180 passed, placing some restrictions on how ALPRs may be used in the state. However, given the rapid expansion of Flock contracts since then, advocates and critics alike expect the technology to return as a contested issue when the Legislature convenes again in 2027.

The political dynamics around surveillance technology in Idaho reflect a tension familiar to center-right voters: law enforcement agencies emphasizing operational efficiency and public safety outcomes, while constitutional conservatives raise concerns about warrantless data collection on ordinary citizens who have done nothing wrong.

Whether the 2027 Legislature revisits SB 1180’s scope — or moves to expand restrictions — may depend significantly on how the ongoing tort claims in Caldwell and Wilder unfold in the months ahead.
