When President Obama addressed the American Society of News Editors convention last month, the real news was what didn’t happen. The watchdogs didn’t bark. No discouraging word from the gathering of 1,000 of the country’s top news people, facing a president whose administration has led a vigorous attack on journalism’s most indispensable asset — its sources.

Obama took office pledging tolerance and even support for whistleblowers, but instead is prosecuting them with a zeal that’s historically unprecedented. His Justice Department has conducted six prosecutions over leaks of classified information to reporters. Five involve the Espionage Act, a powerful law that had previously been used only four times since it was enacted in 1917 to prosecute spies…

…As Steven Aftergood, director of the Federation of American Scientists’ government secrecy project, put it: “The administration’s aggressive pursuit of leaks represents a challenge to the practice of national security reporting, which depends on the availability of unauthorized sources if it is to produce something more than ‘authorized’ news.”

What’s behind the administration’s fervor isn’t clear, but the news media have largely rolled over and yawned. A big reason is that prosecutors aren’t hassling reporters as they once did. Thanks to the post-9/11 explosion in government intercepts, electronic surveillance, and data capture of all imaginable kinds — the NSA is estimated to have intercepted 15-20 trillion communications in the past decade — the secrecy police have vast new ways to identify leakers.

So they no longer have to force journalists to expose confidential sources. As a national security representative told Lucy Dalglish, director of the Reporters Committee for Freedom of the Press, “We’re not going to subpoena reporters in the future. We don’t need to. We know who you’re talking to.
