HOW IT WORKS: License Plate Readers

Our Take

When a police department produces its own explainer video on surveillance tech, the goal isn't transparency — it's public buy-in. Denver PD's rundown of how its license plate readers work hits the reassuring notes: crime prevention, stolen cars, wanted plates. What it doesn't spend much time on is who else can access that data, how long Denver holds onto scans of innocent drivers, or whether the system feeds into Flock's larger national network where other agencies, and sometimes ICE, can query it.

That omission is the pattern, not the exception. These videos are built to normalize a technology that quietly logs the location of every car that passes a reader, guilty or not, and stores it for future searching. The actual policy questions — audit trails, retention windows, who signs off on searches — rarely make it into a five-minute department PR piece, because the answers are often less comfortable than 'we caught a stolen car.'

If Denver has these cameras up, they're likely on our camera map already, and if not, they will be soon. Local reporting and public records requests are how residents actually learn what departments won't put in a promotional video — check our take-action page for how to push your city council for real oversight.
