You post an article about tracking sexual molesters, and that's not the topic?
Tracking ex-criminals ought to be part of the sentence. Know where these cretins are, all the time.
The rest of your speculation is tin-foil stuff.
This is going to be a fun thread to watch.
Next time, read the headline and think a little.
Tracking parolees may be authorized legitimately. Tracking criminals who have already paid their debt to society is a different issue.
I agree with RB that the same technology advocated here will probably be used in association with the 'mark of the beast'. It will indubitably be researched to evolve towards a bidirectional neural networking device with the intention of influencing the wearer's thoughts. I suspect such goals are the upper limit closely approaching the 'end time'.
For these reasons, IMHO, RB's association of this technology leading to the mark is prudent.
