Senator Hawley Launches Senate Investigation Into Flock Safety License Plate Reader Network

St. Charles County Police Department terminated its contract with Flock after an audit revealed a civilian employee had run Flock searches for personal reasons.
In Milwaukee, a police officer allegedly searched his girlfriend’s license plate 124 times and her former boyfriend’s plate 55 times; the misconduct was not caught by Flock’s audits and was uncovered when a private citizen checked his own plate on a public site.
A Florida woman spent 13 days in jail and faced multiple felony counts after investigators mistakenly arrested her based on a search of Flock’s network.
Flock Safety reports contracts with more than 5,000 police departments across 49 states.
Senator Josh Hawley is opening a formal Senate investigation into Flock Safety's nationwide license plate reader network, demanding detailed documents by September 8, 2026. Courthouse News reports the company operates more than 120,000 cameras across 49 states, performing roughly 20 billion vehicle scans each month. Hawley argues the system functions as a mass surveillance program with weak oversight and limited safeguards.
The probe focuses on repeated misuse. News Break highlights a Milwaukee officer who searched his girlfriend's license plate 124 times and her ex-boyfriend's plate 55 times — behavior Flock's audits never caught. A civilian worker in St. Charles County, Missouri also ran personal searches before the department terminated its contract. Meanwhile, a Florida woman spent 13 days in jail after investigators arrested her based on a mistaken plate reader match.
The Missouri Republican requested documents covering how Flock collects, stores, and shares vehicle data. Washington Examiner notes Hawley also wants records on enforcement access policies, camera placement decisions, all government contracts, and revenue sources from investors and police departments. The inquiry specifically seeks evidence of known or suspected misuse since 2021.
Flock Safety operates under contracts with more than 5,000 police departments across 49 states, according to KOMU. The company claims its technology has supported roughly 1 million investigations and helped locate about 10,000 missing people. Flock has already signaled cooperation with Hawley's probe, saying it will provide explanations of how its system works and how officers use it in the field.
St. Charles County terminated its Flock contract after an internal audit discovered a civilian employee had run searches for personal use. The Milwaukee case proved more troubling: an officer conducted 179 searches on his girlfriend's and ex-boyfriend's plates without detection. Daily Signal notes a private citizen uncovered this misconduct only by checking his own plate on Flock's public website.
Inaccurate matches have led to wrongful arrests. A Florida woman spent two weeks in jail and faced multiple felony charges after investigators mistakenly identified her vehicle in Flock's database. These incidents reveal gaps in both Flock's internal oversight and the safeguards protecting drivers from misidentification errors.
