> "What if the government mistakenly determines that based on your pattern of activities, you're likely to engage in a criminal act? What if it denies you the right to fly? What if the government thinks your financial transactions look odd—even if you've done nothing wrong—and freezes your accounts?"

That's a lot of ifs. I don't think it really has anything to do about privacy issues. Privacy issues created those "ifs". That's a paranoid state, not a state of law and rights. Those are issues created by society unable to sort its things. I doubt a government can really forbid things based on information, and if so, it already existed before.

Of privacy issues make things worse, but those issues were the mix of a digital age and terrorism. Nobody can escape the fact congress will vote laws and agencies will want to work on things.
