  Why should Icare about NSA etc? • presumption of guilt vs. modern law presumption of innocence. • false positives • nobody knows about future, Bruce Schneir: it is not about “nothing to hide” – it’s that we have everything to lose • transferring power to security organisations • the loss of personal data control • misuse, enormous overcollecting will lead to misuse, sooner or later. By government or individuals. There is huge money making possibilities • Obama 17.1.2014: ”No more massive collection, as long as I’m the president” (but what after that?) One false positive case, David Mery entered to the subway wearing a jacket in warm weather, an algorithm monitoring the CCTV Dacid suspicious. The police arrested him, and checked his flat. Though he was never convicted of a crime, Mery is still on file as a potential terrorist eight years later, and can't get a visa to travel abroad. http://www.theguardian.com/technology/blog/2013/jun/14/nsa-prism
