You simply have to eventually fall under suspicion from somebody even by a wrong call. And then they can use this system to go back in time and scrutinize every decision you've ever made, every friend you've ever discussed something with. And attack you on that basis to sort to derive suspicion from an innocent life and paint anyone in the context of a wrongdoer.

We should never allow computers to make inherently governmental decisions in terms of the application of military force, even if that's happening on the internet.

The issue I brought forward most clearly was that of mass surveillance, not of surveillance in general.

Every time you pick up the phone, dial a number, write an e-mail, make a purchase, travel on the bus carrying a cell phone, swipe a card somewhere, you leave a trace, and the Government has decided that it's good idea to collect it all, everything, even if you've never been suspected of doing a crime.
