The capacity to do selective enforcement is a huge issue in itself. Let's say you bring corruption charges to light, or advocate for something people in power don't like, or even just cut off someone's angry nephew in traffic. In a country with a rule of law, that's okay --- you're safe. You can't just be arbitrarily punished. But with this? No problem. They just tell the NSA to flag you, and as soon as you do _anything_, they'll get you. Better still if the data's retroactive --- if they can track everyone, and figure out that three years ago you caught a fish and transported it across state lines or whatever. If you have a legal system that classes a majority of people as technically a criminal, and the capacity to selectively enforce that, then congratulations, you've got despotism.
