Standing on a San Francisco rooftop, looking out at the infinite grid of lights and traffic, I was struck by a simple, unsettling thought: every car below was potentially a data point in a national surveillance network. This isn’t science fiction. It’s the reality built by Flock Safety, a company whose 120,000 automatic license plate readers form a digital dragnet across America. Today, that company announced a series of policy shifts, an attempt to tighten the reins on a system critics say has grown too powerful and too prone to abuse.
The changes, while incremental, are a direct response to a firestorm of bad press and lost municipal contracts. At the heart of the controversy is a fundamental question of power: what happens when a tool built to find stolen cars becomes a mechanism for personal vendettas? A recent Washington Post investigation put a number to the fear, documenting 46 cases where officers were accused of using Flock’s cameras to stalk current or former romantic partners. In response, Flock is now mandating that officers enter a criminal case number before a search. It’s a baseline accountability measure long demanded by civil liberties groups like the ACLU.
But as Chad Marlow, senior policy counsel at the ACLU, pointed out to me, the history of such safeguards is not encouraging. “When Flock previously required a ‘reason’ for a search, officers entered things like ‘investigation’ or even ‘hehehe,’” he said. Since Flock won’t verify the validity of case numbers, the new rule relies on an honor system. The company’s answer is an expanded, mandatory automatic auditing tool that flags suspicious search patterns to administrators. Yet Flock has not shared this system’s accuracy rates or opened it to independent evaluation, leaving its effectiveness an open question.
The backlash against Flock is a patchwork of concerns, stitching together privacy activists, concerned citizens, and even unlikely critics like Tucker Carlson, who has lambasted the technology as a pillar of a “slave state.” The activist group DeFlock tracks contract cancellations, which NPR found included at least 30 cities in the past year. Some municipalities are banning the cameras outright; others are switching to competitors like Axon or Motorola. Flock CEO Garrett Langley frames the losses differently. In an interview with MIT Technology Review, he attributed much of the pushback to “misinformation,” such as beliefs that Flock performs facial recognition or sells data commercially.
Yet, as Marlow notes, the misinformation charge is a two-way street. “We have documented the company repeatedly lying to city councils about what its technology can do,” he told me. The deeper issue, he argues, isn’t just isolated abuse but the system’s sheer scale. “In America, you only get to investigate someone if you think they’ve done something wrong,” Marlow explained. “These cameras flip that. They allow for investigation without suspicion, all without a warrant.” He poses the existential trade-off: “Is it worth it to catch a certain number of criminals, return a certain number of stolen cars, to eviscerate Americans’ privacy?”
Flock’s other new rules nod toward this broader unease. The company now recommends agencies retain data for seven days instead of 30 and it allows departments to restrict searches from other jurisdictions—forbidding uses like “immigration enforcement” while permitting “kidnapping” investigations. Again, these safeguards depend on officers accurately tagging their searches.
From my conversations within the tech policy world, Langley’s statement to MIT Technology Review is the most revealing. He described a shift “from building things that are optional” to “building more confidence that as a technology company we have a responsibility to enforce guardrails, not provide optionality.” This is a significant, if belated, admission for the surveillance industry: that building the tool comes with an inherent duty to control its use.
Still, for Marlow and others, these steps are merely tactical concessions. “Flock has come to the table because this incredible, unprecedented nationwide uprising against their company has scared them,” he said. “But they are just absolutely unwilling to make the actual changes they need to make.” The real test will be transparency—opening its systems to independent auditors—and whether these digital guardrails can withstand the very human impulses they are designed to curb.
Watching the cars flow through the city, I’m left with a technological tautology. We build systems of immense power to solve real problems, like auto theft. But without equally powerful safeguards, built not as optional features but as foundational ethics, the tool itself can become the problem. Flock’s new rules are a start, a recognition of that tension. But in the silent audit logs and unverified case numbers, the old problem remains: who watches the watchers?
