I think it depends very much on how they're used. If they're set up to flag stolen vehicles and vehicles owned by fugitives and don't store irrelevant license plate numbers long-term, I have no complaints. I think in practice they often record every plate and store the data long-term, which can be used to track people who are not active targets of an investigation.
