Do you drive a car in Los Angeles? You do? Get up against the wall you criminal scumbag! You have the right to remain silent, everything you say can and will be recorded and saved with your license plate data. The agencies took a novel approach in the briefs they filed in EFF and the ACLU of Southern California's California Public Records Act lawsuit seeking a week's worth of Automatic License Plate Reader (ALPR) data. They have argued that "All [license plate] data is investigatory." The fact that it may never be associated with a specific crime doesn't matter.
