This indirectly makes a great point. While everyone's been talking about the danger of a turn-key totalitarian state -- the danger of intentional totalitarianism -- much less has been made of the danger of an unintentional totalitarian state arising from overzealous use of these systems by law enforcement. I think that's a much greater immediate risk.

Replace "DUI pattern detected" with "likely child predator." Just the insinuation that a person is a pedophile can destroy a person's life.
