Detective Brian Ralph can scan up to 3,000 tag numbers a shift, searching for stolen vehicles and violent criminals.
“So if someone is looking for a particular vehicle in reference to a robbery or murder or something like that, we can put that tag number into the system and it will hit if the vehicle happens to drive by,” said Hartman, Regional Auto Theft Task Force.
More than 320 LPRs are in use across Maryland. Information about every scanned license plate–even non-criminal–is stored at the Maryland Coordination and Analysis Center. That concerns the ACLU.
“As the data increases over time you get a more detailed picture of Marylanders’ movements. And that is information the government has no business knowing, absent some particular law enforcement need,” said David Rocah, ACLU.
