Los Angeles City Council is considering sending "Dear John" letters to the registrants of cars seen in an area of San Fernando described as having a "thriving street prostitution problem". The plan would use automated license plate readers to identify vehicles that stopped in the area. Council member Nury Martinez claims "If you aren’t soliciting, you have no reason to worry about finding one of these letters in your mailbox. But if you are, these letters will discourage you from returning."
