Through all the bombast, Greenwald makes no serious effort to defend as a matter of law the leaking of official secrets to reporters. He merely asserts that “there are both formal and unwritten legal protections offered to journalists that are unavailable to anyone else. While it is considered generally legitimate for a journalist to publish government secrets, for example, that’s not the case for someone acting in any other capacity.”

Here at last, I thought, is something Greenwald and I can agree on. The Constitution is for everyone. There shouldn’t be a special class of people called “journalists” with privileges like publishing secret government documents.

But no. Greenwald’s only problem with the idea of a journalist’s privilege is that some people don’t recognize that he’s a journalist. He is right that he is just as entitled to this honor as Bob Woodward. But so is everyone else. Especially in the age of blogs, it is impossible to distinguish between a professional journalist and anyone else who wants to publish his or her thoughts. And that’s a good thing.

The Snowden leaks were important — a legitimate scoop — and we might never have known about the N.S.A.'s lawbreaking if it hadn’t been for them. Most leaks from large bureaucracies are “good” leaks: no danger to national security, no harm to innocent people, information the public ought to have.

The trouble is this: Greenwald says that Snowden told him to “use your journalistic judgment to only publish those documents that the public should see and that can be revealed without harm to any innocent people.” Once again, this testimony proves the opposite of what Greenwald and Snowden seem to think. Snowden may be willing to trust Greenwald to make this judgment correctly — but are you? And even if you do trust Greenwald’s judgment, which on the evidence might be unwise, how can we be sure the next leaker will be so scrupulous?

The question is who decides. It seems clear, at least to me, that the private companies that own newspapers, and their employees, should not have the final say over the release of government secrets, and a free pass to make them public with no legal consequences. In a democracy (which, pace Greenwald, we still are), that decision must ultimately be made by the government. No doubt the government will usually be overprotective of its secrets, and so the process of decision-making — whatever it turns out to be — should openly tilt in favor of publication with minimal delay. But ultimately you can’t square this circle. Someone gets to decide, and that someone cannot be Glenn Greenwald.

Greenwald’s notion of what constitutes suppression of dissent by the established media is an invitation to appear on “Meet the Press.” On the show, he is shocked to be asked by the host David Gregory, “To the extent that you have aided and abetted Snowden, . . . why shouldn’t you, Mr. Greenwald, be charged with a crime?” Greenwald was so stunned that “it took a minute to process that he had actually asked” such a patently outrageous question.
