The first is this, from Snowden, in an exchange with Washington Post reporter Barton Gellman (Gellman's debriefing is a remarkable read, as is a Q&A between Snowden and his contacts at the Guardian). Asked, "Did he impute evil motives to his former colleagues, or the White House?", Snowden responded:
“Analysts (and government in general) aren’t bad guys, and they don’t want to think of themselves as such,” he replied. But he said they labored under a false premise that “if a surveillance program produces information of value, it legitimizes it."
