We don't have a great clash of civilizations, a clash of ideologies, a clash of alternative models, where governments thought to themselves, if we go too far, if we sort of trample unreasonably on rights, we'll give birth to a political movement which will cost us our credibility, and will possibly cost us our offices, because people will vote for the other team, the other guys.

We can plant bugs in machines. Once you go on the network, I can identify your machine. You will never be safe whatever protections you put in place.
