Flock Mandates License Plate Audit Tool Without Accuracy Data
Flock cuts recommended plate-data retention to seven days and mandates Audit Assistance, but offers no efficacy rates, methodology or independent audit.
Summary
Surveillance startup Flock on Thursday, August 13, 2026, recommended police reduce automated license plate reader data retention from 30 days to seven. Evidence Mode allows longer retention for exceptional cases with a specific case number, and customers can restrict data sharing by investigated offense. Audit Assistance, launched in April and active at more than one-third of customers, becomes mandatory by year-end; it flags atypical searches, documents review and can lock users pending administrator action.
Flock says the tool is neither machine learning nor AI. It cites one plate searched under multiple case codes as a possible abuse signal; trust and compliance head Ashley Haber cited odd search histories, co-founder Paige Todd cited repeated searches for one plate beyond 30 days, and Major Patrick Krieg of Georgia’s Dunwoody Police Department called it an algorithm that detected possible bias. Flock claims it has stopped abuse but has not disclosed detailed mechanics, effectiveness statistics, false-positive and false-negative rates or a third-party audit. TechCrunch also asked what data informs it and what activity it flags.
After years of reported misuse, three former Georgia sheriff’s deputies were arrested earlier that week for allegedly using Flock cameras to stalk people with whom they had personal relationships; Bibb County Sheriff David Davis credited Audit Assistance. American Civil Liberties Union counsel Chad Marlow said dozens of officers have been arrested, fired or disciplined, but absent a violator total the tool could catch 95% or 5% and needs independent evaluation. Electronic Frontier Foundation researcher Cooper Quintin said police could evade it and internal reporting cannot ensure accountability, urging legal limits and warrants. Brennan Center program director Rachel Levinson-Waldman called mandatory use positive in theory but also demanded an audit.
Positives
- Seven-day recommended retention replaces Flock’s previous 30-day period for automated license plate reader data.
- Evidence Mode requires a specific case number before customers retain data longer for exceptional cases.
- More than one-third of Flock customers have activated Audit Assistance since its April launch, with adoption becoming mandatory by year-end.
- Offense-based controls will let customers restrict what license plate data they share with other customers.
- Bibb County Sheriff David Davis credited Audit Assistance with uncovering alleged misuse by three former Georgia sheriff’s deputies.
Risks & concerns
- Flock has disclosed no effectiveness statistics, false-positive or false-negative rates, detailed methodology or independent audit for Audit Assistance.
- Three former Georgia sheriff’s deputies were arrested for allegedly using Flock cameras to stalk people with whom they had personal relationships.
- Chad Marlow said unknown violator totals mean Audit Assistance might detect either 95% or just 5% of misuse.
- Cooper Quintin warned police could evade the tool and that reporting suspected abuse to the same agency cannot ensure accountability.
- Evidence Mode still permits retention beyond seven days, although it requires an exceptional case and specific case number.
