There was a real choice when [Barack Obama] became president. It was a very difficult choice - to say, "We're not going to hold senior officials to account with the same laws that every other citizen in the country is held to," or "This is a nation that believes in the rule of law."

The government has granted itself power it is not entitled to. There is no public oversight. The result is people like myself have the latitude to go further than they are allowed to.

I know that fundamentally, changes to the fabric of the internet, and sort of our methods of communication, can enforce our rights.

Congress hasn't declared war on the countries - the majority of them are our allies - but without asking for public permission, NSA is running network operations against them that affect millions of innocent people. And for what? So we can have secret access to a computer in a country we're not even fighting?

On the other hand, the Internet is there to fill needs that people have for information and socialization. We get this sort of identification thing going on nowadays because it's a very fractious time. We live in a time of troubles.

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.

They still have negligent auditing, they still have things going for a walk, and they have no idea where they're coming from and they have no idea where they're going. And if that's the case, how can we as the public trust the NSA with all of our information, with all of our private records, the permanent record of our lives?
