Its more than just Law Enforcers and Dictators (Score 1)

I agree totally that this could be dangerous in the hands of some governemt. However, there is another danger to consider. This same devise could also be used for the "good" of people pressumed not able to make valid choices, either by well meaning bumblers or corrupt individuals standing to make a proffit. (To get an idea of what I'm talking about, look ar http://www.madnation.org/.) The kind of governmental parenting advocated in recent years makes this use more likely to be approved in (supposedly) more "enlightened" societies. Considering the constant "bracket creep" in mental "health" anyone seen as eccentric or "disturbed" could be in dangered by this sort of tracking.

But, then, this was probably only a mater of time....
