The story is the same one that all anti-surveillance, anti-police militarization, pro-privacy, and anti-authoritarian people foretell. Good technology will be used enable, amplify, and justify civil rights abuses by authority figures from your local beat cop, to a faceless corporation, a milquetoast public servant, or the president of the United States.
Our institutions and systems (and maybe humans in general) are not robust enough to cleanly handle these powers, and we are making the same mistake over and over and over again.
