Homemade GPS jammers raise concerns - Computerworld
In modern post 9-11 America, it's nice to see this kind of work. I'm a strong supporter of getting the terrorists/bad-guys. I don't support, however, creating a government gestapo that can run a-muck stomping on Civil-Liberties as they see fit. This is America, damn it. If I don't want the man to be able to track me by GPS, then I have every right to block him from doing it. Maybe I'll build one of these things just on principle.
