We are no longer citizens, we no longer have leaders. We're subjects, and we have rulers.

You are also asked to take an oath, and that's the oath of service. The oath of service is not to secrecy, but to the Constitution - to protect it against all enemies, foreign and domestic. That's the oath that I kept, that James Clapper and former NSA director Keith Alexander did not. You raise your hand and you take the oath in your class when you are on board. All government officials are made to do it who work for the intelligence agencies - at least, that's where I took the oath.

When you are subverting the power of government, that's a fundamentally dangerous thing to democracy.

We have these traditional political parties that are less and less responsive to the needs of ordinary people, so people are in search of their own values.

We've already seen, in practically every country around the world where these issues have been covered, that the general public has recoiled at the ideology behind these programs.

We can still publicly post a message to Facebook that's globally readable. But we could also adjust things so that they can only be shared with those closest to us, and the confident that this is enforced through both legal and a systemic standards-based protection.

All the governments just want to have more power when it comes to economic espionage, diplomatic manipulation and political influence.
