How Police Track Your Car With License Plate Cameras

Our Take

Credit to the Daytona Beach Lawyer channel for pulling back the curtain on how ALPR networks actually get used in a live criminal case, not just in theory. The story of Lindsey Isaacs — arrested based partly on Flock Safety and Motorola Vigilant data tying her black Dodge Durango to a fatal I-4 crash, only to have charges dropped and another woman arrested later — is exactly the kind of cautionary tale we keep beating the drum about. Plate readers don't identify people. They identify plates, vehicle shapes, and colors, and then investigators fill in the rest with assumptions. When those assumptions are wrong, someone can end up in handcuffs for a crime they had nothing to do with.

This isn't a one-off glitch, it's a structural risk baked into how these systems are marketed and deployed. Police departments buy Flock and Vigilant networks promising fast, objective leads, but the objectivity stops the moment a human decides which 'hit' matches their theory of the case. Once that decision is made, it can snowball through affidavits, arrest warrants, and headlines before anyone double-checks the math. Lindsey Isaacs got her charges dropped, but not everyone is so lucky, and the reputational and financial damage from a wrongful arrest doesn't just disappear when a prosecutor says 'never mind.'
