When the government grabs every single fucking telephone call made from the United States over a period of months and years, it is not a prelude to monitoring anything in particular. Why not? Because that is tens of billions of phone calls and for the love of god, how many agents do you think the FBI has? How many computer-runs do you think the NSA can do? When the government asks for something, it is notable to wonder what they are seeking and for what purpose. When they ask for everything, it is not for specific snooping or violations of civil rights, but rather a data base that is being maintained as an investigative tool.
In other words, he's completely oblivious to the game-changing effects of highly scalable data mining and machine learning.
