Source for the Guardian's NSA files on why he carried out the biggest intelligence leak in a generation – and what comes next
Q: Why did you decide to become a whistleblower?
A: "The NSA has built an infrastructure that allows it to intercept almost everything. With this capability, the vast majority of human communications are automatically ingested without targeting. If I wanted to see your emails or your wife's phone, all I have to do is use intercepts. I can get your emails, passwords, phone records, credit cards.
"I don't want to live in a society that does these sort of things … I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under."
Q: But isn't there a need for surveillance to try to reduce the chances of terrorist attacks such as Boston?
A: "We have to decide why terrorism is a new threat. There has always been terrorism. Boston was a criminal act. It was not about surveillance but good, old-fashioned police work. The police are very good at what they do."
Q: Do you see yourself as another Bradley Manning?
A: "Manning was a classic whistleblower. He was inspired by the public good."
Q: Do you think what you have done is a crime?
A: "We have seen enough criminality on the part of government. It is hypocritical to make this allegation against me. They have narrowed the public sphere of influence."
Q: What do you think is going to happen to you?
A: "Nothing good."
Q: Why Hong Kong?
A: "I think it is really tragic that an American has to move to a place that has a reputation for less freedom. Still, Hong Kong has a reputation for freedom in spite of the People's Republic of China. It has a strong tradition of free speech."
Q: What do the leaked documents reveal?
A: "That the NSA routinely lies in response to congressional inquiries about the scope of surveillance in America. I believe that when [senator Ron] Wyden and [senator Mark] Udall asked about the scale of this, they [the NSA] said it did not have the tools to provide an answer. We do have the tools and I have maps showing where people have been scrutinised most. We collect more digital communications from America than we do from the Russians."
