Constitutional amendment to protect geo-privacy

Following my earlier note about a new program to implement RFID in our passports, perhaps it's time to start thinking about an actual constitutional amendment to protect privacy, including geo-privacy (the right to control our own locational information).

There's an interesting blog entry about this here. That way we could short-circuit all the debate over whether a right to privacy exists each time we get a Supreme Court nominee. A large majority of Americans are in favor of such a right after all.
