An anonymous reader writes: The city of Los Angeles is considering a new plan to fight prostitution: sending letters to men who solicit prostitutes in the hopes that the letters are seen by family members. Why not just arrest them while they're doing it? Because these letters aren't being sent to the houses of men who were convicted, or even arrested. Instead, automated license plate readers would scan the cars driving down streets known to have a prostitution problem, and the letters would be sent to the address associated with those vehicles. An article about the plan says, "There isn't 'potential' for abuse here, this is a legislated abuse of technology that is already controversial when it's used by police for the purpose of seeking stolen vehicles, tracking down fugitives and solving specific crimes."
