Three Gwinnett County police officers have been fired and arrested after an internal investigation found they misused the department's Flock license plate reader system, and officials say more charges could still be coming. Officers Renee Downer, Matthew Lau, and Derric Holmes were each accused of accessing license plate data without a legitimate law enforcement purpose, according to authorities.
The case broke open after Downer was first arrested in May on charges of simple battery and stalking following a domestic dispute involving her partner, as reported by CBS News. During that investigation, officials discovered she had allegedly used law enforcement databases to obtain location information on the victim, according to FOX 5 Atlanta. That discovery reportedly triggered a broader look at how officers were using the Flock system across the department.
Lau was arrested and charged with one count of misuse of license plate data, per authorities, while Holmes faces six counts of misuse of license plate data, according to the same CBS report. Officials said additional charges may still be filed as the investigation into misuse of the county's Flock license plate cameras continues.
How the Audit Caught the Pattern
Gwinnett County Police gained access to Flock's auditing system in June 2026, giving supervisors the ability to examine individual search activity for the first time. That tool, described by Flock Safety senior public affairs director Trevor Chandler in comments to WSB-TV, is designed to flag abnormal search patterns such as off-duty queries or repeated lookups on a single plate. The station's report notes the feature was built specifically to help departments catch this kind of internal abuse.
Gwinnett's case is not isolated. CBS News reported in July that personnel across at least 17 Georgia law enforcement agencies had been arrested, terminated, investigated, or disciplined for improperly accessing license plate reader systems for personal reasons — a wave of enforcement that has also touched a Clayton County deputy and other agencies across the state. On September 2, state authorities separately arrested a Clayton County deputy and a Georgia Department of Corrections Special Agent in concurrent investigations into Flock camera abuse, according to FOX 5 Atlanta.
Tighter Rules on Searches and Data Retention
Gwinnett County Police Chief J.D. McClure said the department acted immediately after identifying the misuse and made significant changes to limit access and strengthen oversight. McClure described Flock as an extremely important crime-fighting tool, one that has helped identify vehicles connected with homicides and kidnappings and helped locate individuals with dementia and other missing persons, per the CBS report.
Under the department's new rules, officers must justify any license plate search to a direct supervisor, who evaluates the request and then conducts the search rather than allowing officers unrestricted access. The department also mandated that all officers undergo retraining on use of the Flock system and cut its data retention period from 30 days down to 15 days. That 15-day window is well below the 30-month maximum that Georgia Code § 35-1-22 allows agencies to retain plate data absent an ongoing investigation, according to Finding Flock.
State law already treats this kind of misuse seriously. Georgia Code § 35-1-22 makes requesting, obtaining, or using captured license plate reader data for any non-law enforcement purpose a misdemeanor of a high and aggravated nature, punishable by up to 12 months in jail and fines up to $5,000. The same statute exempts captured plate data from disclosure under Georgia's Open Records Act, meaning residents cannot file public records requests to see where their own vehicles have been tracked — leaving internal audits like the one that caught Downer, Lau, and Holmes as the primary check on misuse.
A Network Built With Community Money
Gwinnett County Police have deployed more than 800 Flock cameras countywide, with roughly 680 of those units funded directly by local businesses, homeowners associations, and community improvement districts, according to Flock Safety. The cameras feed into the department's Gwinnett Safe Communities initiative, which is powered by FUSUS technology and links public safety cameras with registered business and residential camera networks, per Gwinnett County Government.
That scale has fueled public unease well before this week's arrests. In July, county commissioners faced heavy pushback at a board meeting as residents called for canceling the county's contract for 1,100 license plate reader cameras over privacy and surveillance concerns, according to a report covered by WSB-TV. Gwinnett police maintain the technology helps officers find missing and endangered people and receive alerts about vehicles allegedly tied to criminal activity, but the department says it will now evaluate further safeguards for how the technology is used going forward.
