Some Police Keep Car-Tracking Data Forever
Across the U.S., police increasingly use license-plate reading technology that can track the movements of cars. And according to documents released Wednesday, local authorities have a patchwork of rules for storing and using the data, with some deleting it almost immediately and others keeping it indefinitely.
The documents, which were obtained by the American Civil Liberties Union through public records requests, raise questions about whether laws and regulations are keeping up with new surveillance technologies.
