Photo Credit: New Yorker Since Edward Snowden’s revelations about government surveillence, we know more about how the National Security Agency has been interpreting Section 215 of the Patriot Act and Section 702 of the Foreign Intelligence Surveillance Act. We’ve learned some new words —“bulk metadata,” “selector,” “reasonable articulable suspicion,” “emphatic-access restriction”—but we don’t really know how much of this works in practice.
The intelligence community isn’t used to explaining itself in public, but over the past few months, with much prodding by Congress and the press, it has taken some small, tentative steps. Last week, I spent an hour with General Keith B. Alexander, who retired in March after eight years as the director of the N.S.A. The forces pushing for omnivorous data collection are larger than any one person, but General Alexander’s role has been significant. We met on Wednesday morning, in the conference room of a public-relations firm in the Flatiron District. He is a tall man with a firm handshake and steady eyes who speaks rapidly and directly.
Here are excerpts from the interview.
In January, President Obama claimed that the N.S.A. bulk-metadata program has disrupted fifty-four terrorist plots. Senator Patrick Leahy said the real number is zero. There’s a big difference between fifty-four and zero.
Those [fifty-four events] were plots, funding, and giving money—like the Basaaly Moalin case, where the guy is giving money to someone to go and do an attack. [Note: Moalin’s case is awaiting appeal.] It’s fifty-four different events like that, where two programs—the metadata program and the 702 program—had some play.
I was trying to think of the best way to illustrate what the intelligence people are trying to do. You know “Wheel of Fortune”? Here’s the deal: I’m going to give you a set of big, long words to put on there. Then I’m going to give you some tools to guess the words. You get to pick a vowel or a consonant—one letter. There’s a hundred letters up there. You’ll say, I don’t have a clue. O.K., so you’ve used your first tool in analysis. What the intelligence analysts are doing is using those tools to build the letters, to help understand what the plot is. This is one of those tools. It’s not the only tool. And, at times, it may not be the best tool. It evolved from 9/11, when we didn’t have a tool that helped us connect the dots between foreign and domestic.
