Database mix-ups happen all the time, systems are hacked, data isn't kept up-to-date between applications, the phone lines go down in Bangalore....
A 75 year-old man from South Dakota could suddenly be labeled a "terrorist," and could be whisked away in the middle of the night, detained in some holding cell. What rights would one have against "the system?"
My response was . . . sarcasm. Hence the /s at the end. As mentioned after me, Biblical verses indicate a marking (and tracking) mechanism for each human will allow a global government to control every human on earth. No buying or selling without the mark is pretty strong medicine to induce the will of the (demonically ran) government. One would lose all earthly possessions. No job. No visible means of support. No security except knowing one did not receive the Mark. You may preserve your soul but the odds will be good you will lose your life.
