What are license plate readers - and why are they a privacy concern?

Our Take

Credit to ACLU Michigan for putting plain language behind a problem we harp on constantly: these cameras aren't watching for one bad guy, they're logging everybody. A plate scanner mounted on a bridge or squad car doesn't care if you're a suspect — it grabs your plate, time, and location, and files it away regardless of whether you've ever done anything wrong. That's the whole trick of mass surveillance infrastructure: it doesn't need probable cause because it's collecting first and justifying later.

What makes this video worth your time is the reminder that "who has access" is just as important as "what gets collected." Flock and its law-enforcement customers love to talk about solving crime, but the same database that flags a stolen car can just as easily map out someone's commute, their church, their doctor's visits, or a protest they attended. Once that data exists, retention policies and info-sharing agreements decide how far it travels — and those are usually written with zero public input.

If you want to see how far this network already reaches near you, check our camera map, and if you're ready to push back on your local city council or police department, our take-action page has the tools to get started.
