As cities reevaluate their use of automated license plate readers (ALPRs) made by Flock Safety, the conversation often centers on the tension between solving crimes and protecting civil liberties. Yet defenders of the technology frequently miss a critical dimension: how the company's design choices—not just the fact of surveillance—shape that trade-off.
In 2026, with over 4,000 municipalities using Flock systems, the stakes have never been higher. The devices capture not only license plates but also vehicle characteristics, travel patterns, and occasionally faces or drivers' behaviors, storing data for up to 30 days (or longer with paid tiers). This mass data collection goes far beyond the reactive, targeted surveillance of the past, raising questions about proportionality and necessity.
The Design Choices That Matter
Flock's defenders argue that the cameras are merely 'digital eyewitnesses,' aiding law enforcement in recovering stolen vehicles and locating missing persons. However, the company's default settings—such as indefinite data retention unless police departments opt out, and sharing across jurisdictions via a national network—expand the surveillance net far beyond a single investigation.
Moreover, the analytics features, like vehicle 'fingerprinting' and behavioral pattern detection, are sold as crime-prevention tools. But they also enable predictive policing models that can disproportionately affect marginalized communities. A 2025 study by the Electronic Frontier Foundation found that ALPR data, including Flock's, was accessed by non-law-enforcement entities in over a dozen documented cases, raising concerns about mission creep and potential misuse.
Missing the Forest for the Trees
Proponents often cite high-profile recoveries of stolen cars or arrests made possible by Flock's alerts. However, they rarely address the absence of robust independent oversight—most contracts lack clear data governance rules, and audits are rare. In 2026, as the Federal Trade Commission begins drafting new guidelines for commercial surveillance technologies, these gaps could become regulatory flashpoints.
Furthermore, the company's own marketing emphasizes 'proactive policing,' but independent studies suggest that ALPRs have a modest impact on overall crime rates, while generating thousands of leads that officers must manually sort through—a resource drain that could be allocated to community-based strategies with proven effectiveness.
Rethinking the Balance
The core issue isn't whether Flock's technology has benefits—it does—but whether the current design prioritizes surveillance capacity over civil liberties. For example, the option to blur faces and delete data after 24 hours exists, but is not the default in many contracts. If defenders truly believe in the technology's value, they should advocate for stricter defaults, transparent usage policies, and meaningful public consent mechanisms.
As cities like San Francisco and Boston have already banned or restricted ALPRs in 2025–2026, the debate is shifting from 'if' to 'how' these tools should be governed. The onus is on defenders to engage with these design-level critiques, rather than dismissing them as anti-technology sentiment. Otherwise, they risk winning the battle over a single tool while losing the public's trust in the broader promise of AI-driven public safety.
