If you buy into incrementalism, a good argument could be made that first the SSN, then the UPC, were forerunners, not necessarily by one group's conscious design, of building a system within which a sophisticated, full-blown, enhanced RFID system can operate.
I don't know for certainty what the MOB is or is not or if it is even literal. All I know is where I hope I draw the line personally.
No one should be forced to take it against their will. There should be certain basic human rights for even criminals. Much as I loathe certain *categories* of sex offendors and other criminals, I have a problem with chipping *anyone* against their will, same as I do with illegals, drunk drivers, terrorists, or any other class of lawbreakers.
Too many people seem to think it's ok for criminals. I'm not comfortable with that kind of thinking, an electronic ankle bracelet is bad enough, but I've gone along with it for other people. If they are truly a menace to society, keep them locked up. If not, let them serve their punishment and go on their way unhampered by the humiliation of electronic monitoring.
With all the surveillance out there now, it's pretty hard for anyone to escape the eyes of the law, big brother, the government. They will find you eventually; very few escape as it is now in our country.
With terrorists and illegals whom I don't place in the same category of terrorists, you have to *catch* them first in order to chip them.
