US v Jones

EFF has urged a U.S. appeals court to reject government claims that federal agents have an unfettered right to install Global Positioning System (GPS) location-tracking devices on anyone's car without a warrant.

In this case, FBI agents tagged the car while it was on private property, and then used GPS to track the position of the automobile every ten seconds for a full month, all without securing a warrant. In an amicus brief, EFF and the American Civil Liberties Union of the National Capital Area argue that this opens the door for police to continuously track anyone's physical location for any reason -- never having to go to a judge to prove the surveillance was justified.
