A battle over license-plate readers is brewing in Virginia.

If you are walking down a public street, should you expect people not to see you? Of course not. But suppose someone decides to follow you—and to make records noting the time and place of your movements. Is that the same thing as simply noticing you happen to be out and about? No. Most people would agree the second case differs from the first.
Yet a Fairfax judge unfortunately failed to pick up on that distinction recently when he ruled in favor of the county’s use of license plate readers. Fairfax’s police department uses automated license plate readers that can scan 3,600 plates per minute. The county compares the plates to a hot list of stolen cars and other vehicles that might have been involved in a crime. It also stores the image of every plate, along with the date, time and location of each plate recording, for 364 days.
