The Rise of License Plate Readers in South Dakota: Security Tool or Surveillance Dragnet?

Our Take

Credit to KOTA Territory News for putting the question in the headline instead of burying it: are ALPRs a security tool or a surveillance dragnet? That framing matters because it's rarely an either-or. Flock Safety and its peers market these cameras as narrow crime-fighting tools, but the underlying system logs every plate that passes, not just the ones tied to a warrant. South Dakota is a smaller market for this technology, which makes local reporting like this especially valuable — it's often the only record of how fast these networks are expanding before residents even know they exist.

What tends to get lost in local coverage is the scale question. One camera at one intersection sounds harmless. A statewide network quietly stitched together by a private company, feeding a searchable database that other agencies and even out-of-state departments can query, is a different animal entirely. That's the dragnet part of the equation, and it doesn't require anyone to do anything wrong to get swept into it.

If you're in South Dakota or anywhere else wondering whether this hardware has already shown up near you, check our camera map to see what's been documented in your area. And if you want to push back on unchecked expansion, our take-action resources walk through how to raise the issue with local officials before the network grows any further.
