What is ALPR?
The short version: Monterey Park PD's explainer video is a polished PR pitch for ALPRs that skips the hard questions about data sharing, retention, and abuse.
Our Take
When a police department makes its own explainer video about a surveillance tool, you're not getting a neutral tutorial — you're getting a sales pitch with a badge on it. The City of Monterey Park's "What is ALPR?" video walks viewers through the basics of how license plate readers work, but like most official ALPR explainers, it's light on the parts that actually worry civil liberties watchdogs: who else gets access to that plate data, how long it's stored, and what happens when a camera flags an innocent driver's plate as a false positive.
These videos tend to frame ALPRs as a narrow tool for catching stolen cars and wanted suspects, which sounds reasonable in isolation. What gets left out is the bigger picture — that a single department's camera network often feeds into (or pulls from) a national data-sharing system, that the footage can be queried by other agencies including ICE and out-of-state police, and that there's rarely a public audit trail showing how often that access gets abused or who's being tracked and why. Monterey Park residents deserve that context just as much as the pitch for "public safety."
We appreciate transparency when it happens, but a city-produced video isn't a substitute for independent oversight. If you want to see whether Monterey Park or your own city has ALPR cameras already deployed, check our map, and if you want to push back on unchecked expansion of this technology, our take-action page has tools to get started.
