The government doesn't want us to know what they're doing, how they're interpreting the law, how they're interpreting and redefining their powers, and increasingly, how they're redefining the boundaries of our rights and our liberties, broadly, socially, and categorically without our involvement.

Most of the secrets the CIA has are about people, not machines and systems, so I didn't feel comfortable with disclosures that I thought could endanger anyone.

I have used mass surveillance to target people, so I do know how it works.

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?

You can show a guy sort of peeking over the wall, you can see a guy tunneling underneath, you can see a guy going through the front door. All of those, in cyber terms, are vulnerabilities, because it's not that you have to look for one hole of a specific type. It's the whole paradigm.

And that's a key distinction.
