Edward Snowden, the source of US National Security Agency leaks, has said he left all the leaked documents behind when he flew from Hong Kong to Moscow and there is no chance of them falling into the hands of Russian or Chinese authorities.
In an interview with the New York Times, Snowden said he had decided to hand over all digital material to the journalists he had met in Hong Kong because it would not have been in the public interest for him to hold on to copies. “What would be the unique value of personally carrying another copy of materials onward?”
Snowden disputed speculation that he had run the risk of China and Russia gaining access to the secret files. He said he was so familiar with Chinese spying operations, having himself targeted China when he was employed by the NSA, that he knew how to keep the trove secure from them. “There’s a 0% chance the Russians or Chinese have received any documents,” he said.
The 30-year-old said he had previously been reluctant to disclose that he no longer had the files for fear of exposing the journalists – Glenn Greenwald and Ewen MacAskill of the Guardian, and the independent filmmaker Laura Poitras – to greater scrutiny.
