"The editorial was right when it stated such implantation raises serious legal, ethical and civil rights questions. But first it raises questions of factual accuracy. Why? Because there are no commercially available GPS implants in existence. The Florida company, Applied Digital Solutions (ADS), announced in December of 1999 that it had acquired the patent for a syringe-injectable GPS implant that was powered by muscle movement and could be remotely monitored. The location and movements of the host could be stored in a database for future reference, the company said. ADS recommended use of the technology for tracking felons and prisoners."

Not sure where this (politically oriented) website is going with the story, but some interesting points are raised.
