When cops use Flock to arrest someone in Wapello County, Iowa, they don’t want them to know. A usage policy for the automated license plate reader cameras in the county tells police, in no uncertain terms, to keep them a secret: “DO NOT MENTION ALPR USAGE TO THE OCCUPANTS OF THE VEHICLE,” the policy document reads. “DO NOT MENTION ALPR USAGE IN YOUR REPORT OR COMPLAINT UNLESS ABSOLUTELY NECESSARY.”
The police guidance document is unusual in how clearly it tells police not to mention their Flock use, but it also highlights several important things in the Flock debate. While Flock likes to say that it is a transparent surveillance company and that it cares about “accountability” and “governance,” some of its customers believe its use should be kept secret. Flock is now operating in thousands of cities and towns, and when, how, and why police use the system is wildly inconsistent. Even though Flock does have various auditing and transparency tools, police have their own opinions about what Flock can and should be used for and what the policies for it should be.
It is not just local police in small communities who are creating policies designed to obfuscate Flock usage. Earlier this year, we reported that police in multiple states were being told to be “as vague as permissible” about why they were using Flock because their searches could be obtained using public records requests, and that warning was being shared by the FBI and Department of Justice. Residents of many towns using Flock also say that their cities entered into contracts with Flock with little public oversight, essentially quietly opting them into a nationwide surveillance network without robust public debate.
Wapello County’s “standard operating procedures” document for Flock cameras was created in November of 2025 and was obtained by a 404 Media reader using a public records request and was shared with us. Coincidentally, Wapello County’s largest city is Ottumwa, Iowa, where 404 Media ran a Super Bowl commercial earlier this year. The county has four Flock cameras via a contract it signed with the company in late 2024. The policy further instructs police to be vague in any arrest report, suggesting that they simply call the Flock system “county resources.”
“DO NOT MENTION ALPR USAGE IN YOUR REPORT OR COMPLAINT UNLESS ABSOLUTELY NECESSARY. If asked a direct question about ALPR usage by someone such as an attorney, tell the truth,” it says. “If it is necessary to explain in a report, it is advised to use language such as ‘Using county resources, I discovered the suspect vehicle was bearing an Iowa plate.’ Treat the ALPR information like you would intelligence. It is simply a lead that you verified and acted on.”
The guidance to keep Flock use secret is reminiscent—but less extreme—than guidance on some other secretive police technologies. For years, police tried to hide the existence of cell site simulators (popularly known as Stingrays), going as far as to drop criminal cases where it was likely that a judge would expose information about them. Stingrays are essentially fake cell phone towers that can be used to identify the phones of people in a specific area.
In the public records request, Sheriff Don Phillips said “there is no need” to tell people about the use of Flock.
“Our policy requires deputies to check the license plate to make sure the correct plate is accurate and the information as to an arrest warrant, stolen vehicle, stolen plate or missing person is correct,” he said. “There is no need to tell them about our investigative methods or sources, such as the camera system, because the information is verified by the deputy running the license plate. It is common practice for law enforcement to refrain from disclosing investigative methods and sources to prevent criminals from learning how to circumvent them.”
Phillips did not respond to a request for comment.
