Global Positionin System

Have you heard about Human Tracking? I myself is kind of undecided as to side on the yes or the not use of this human tracking technology that use the Global Positioning System. I mean, what about the privacy of the individual? Honestly, I reallly don't know where to side on this matter. I will have to say that maybe, use this global tracking to those people that would want to have this device. I mean, have the people that freedom of choice. What about you? Whats your stand on this?
