"Snowden had more responsibility at the NSA than people may think, he said. “I was what’s called a systems administrator or a superuser, which means that I had more access than almost any other official in the intelligence community,” he said. “Because even the director of the National Security Agency or the Central Intelligence Agency or any of these things, when they want to see some documents, when they want to understand some program, they have to ask someone: ‘Show me this, tell me about this, brief this for me.’ ”
And that someone was Snowden. “As a systems administrator, you are the person who can see all of that, because you are the one who controls all of the information.”"
