There is a site called Spokeo, where you can just enter someone's name, and it can bring you their exact location, for a payment of 4 dollars. Even if you don't pay, you can find what road and town they live on. It also shows you previous properties they have owned, and even the house they currently live in, its size and worth. This is an utter infringement of the peoples' right of security, and therefore unconstitutional.
