Of course, any news organization can be fooled — The New York Times famously fell short with its reports of supposed weapons of mass destruction in the run-up to the Iraq war — but it was hard to watch the N.S.A. segment and not wonder who was minding the store.

On what planet is it fine for someone like Mr. Miller, a former federal law enforcement official, to be the one to do a big segment on a major government security agency? Mr. Miller got the story because the N.S.A. said yes to his pitch — why would it not? — but other journalists at “60 Minutes” without his potential conflicts were interested as well. No matter how the deal was brokered, the optics were terrible and the N.S.A. got its hands on a megaphone with nary a critic in sight.

Mr. Fager would not speak on the record, perhaps in part because he was pummeled after initially defending the Benghazi broadcast; when it fell apart, he was forced to put Lara Logan, the reporter, and the producer on leave. But while declining to comment, he made it clear that he very much had his eye on the ball at “60 Minutes” and pushed back against any notion of institutional malaise.
