"My greatest fear was that no one would listen to my warning. Never have I been so glad to have been so wrong. The reaction in certain countries has been particularly inspiring to me... At the NSA, I witnessed with growing alarm the surveillance of whole populations without any suspicion of wrongdoing, and it threatens to become the greatest human rights challenge of our time. The NSA and other spying agencies... have revoked our right to privacy and broken into our lives. And they did it without asking the public in any country, even their own. Today, if you carry a cell phone in Sao Paolo, the NSA can and does keep track of your location... When someone in Florianopolis visits a website, the NSA keeps a record of when it happened and what you did there... They even keep track of who is having an affair or looking at pornography, in case they need to damage their target's reputation. There is a huge difference between legal programs, legitimate spying, legitimate law enforcement — where individuals are targeted based on a reasonable, individualized suspicion — and these programs of dragnet mass surveillance that put entire populations under an all-seeing eye... These programs were never about terrorism: they're about economic spying, social control, and diplomatic manipulation. They're about power."
