In an auditorium so large that Columbia’s Journalism School typically only uses it for its graduation ceremonies, hundreds attended the panel discussion “Journalism After Snowden” on Thursday evening. The topic was as vast as it is timely—encompassing the rising tensions between media organizations and their governments, the practical process of protecting sensitive information (digitally) and oneself (legally), and the delicate dance between privacy and power.

Emily Bell, director of the Tow Center at the journalism school (and a member of CJR’s board of overseers), moderated the panel, and she started it off by asking Guardian US Editor in Chief Janine Gibson to give a behind-the-scenes account of the very beginning of the Summer of Snowden. Gibson described how Glenn Greenwald called her in New York shortly after making contact with his then-nameless source, saying something like “I think I have the biggest intelligence leak in a generation, if not ever.”

Gibson was skeptical, but listening; however, she also knew that Greenwald was calling her from Rio over a Skype line. She knew from her previous work on the paper’s WikiLeaks coverage that Skype was relatively untrustworthy technology, and she all but hung up on him. But Greenwald soon flew to New York to meet with her and a few trusted staff members. There, he showed them the tiny sample of stuff he had gotten from his source—starting with the PRISM PowerPoint slides—on a new, air-gapped laptop hastily bought from Best Buy for the occasion.

“You very quickly realize that this is an incredibly huge, sensitive, difficult story—or it’s the Hitler Diaries, it’s a great big hoax,” said Gibson. Then came the story of the now-familiar trip to Hong Kong, and their meeting with an oddly young contractor and his Rubik’s Cube, and the cache of documents of a size that no one has yet been able to quantify.

Verifying that Snowden’s account was legit was one challenge—reporting the story out was an entirely different one. They started with the Foreign Intelligence Surveillance Court order for Verizon metadata. “We were trying to edit, write, report, understand, and verify a document that no one has ever seen,” said Gibson. “You can’t Google ‘secret FISA Court order’ to see if it looks like one that’s in front of you.” The audience laughed at this. “No, that’s not funny, that’s a genuine problem,” she countered, drily.

The conversation shifted to the Guardian’s collaboration with The New York Times as the documents from Snowden kept coming over the following months. Jill Abramson’s first response to Bell’s question about the Times getting involved was an honest memory of her disappointment that her paper hadn’t been first with the scoop. “We did not break the story—the Guardian and The Washington Post did—and that caused me, you know, severe indigestion,” said Abramson.

But both Gibson and Abramson agreed that the partnership between the two papers during this process was invaluable. Tech-savvy reporters and editors at the Guardian educated their peers at the Times about best digital-security practices for communicating, searching, viewing, and storing the classified documents. Then, the Times was able to protect the files when the British government aggressively pursued (and forced editors to destroy) the Guardian’s hard drives in the UK.

The Guardian’s outside counsel, David Schulz, was on the panel as well. He had previously worked with the Times during their WikiLeaks coverage. When asked about the legal challenges to news organizations dealing with such sensitive material, he started with the word “conundrum.” A news organization possessing and then publishing classified documents is “still a legal gray area,” said Schulz.
