In 2023 and 2024, Flock sent 1,427 alerts to the Roseville [CA] Police Department.
Roseville police found that Flock misread license plates in 71% of those alerts.
Max Isaacs, director of technology law and policy with the Policing Project at New York University’s School of Law, described Roseville’s misread data as “stunning.”
“A 71% misread rate is really beyond the pale,” he told Business Insider, referring to Roseville’s reported error rate for stolen and felony vehicle alerts. He added that “in the absence of concrete rules that directly address the problem of misreads, this technology is not safe to be deployed in communities.”



If it’s the responsibility of the party that’s been misidenified to correct the mistake, this was intentional. Putting fines to random people, knowing a proportion won’t fight it, is a foundationional pillar of Authoritarianism. What’s worse is even more work will now need to be done to undo and correc this, because it’s already in place. The lawmakers will try to get the percentage up, instead of removing the system.
