Tin-foil hat alert!!!
The next step would be for the government to monitor you everywhere you go, via a court order. Say the police suspect you of criminal activity. This would be easy to do. They do this at this time now with big rigs on the highway. I just read about a guy doing this with his ex-girlfriend, by implanting a GPS device underneath her car. She would go someplace, then all of a sudden, this guy would just happen to show up, using his computer to track her.
