Glenn Greenwald, the Guardian writer who cultivated Edward Snowden as a source and has broken numerous stories about the nature and extent of secret U.S. surveillance programs, says harmful national security information will be released automatically if "something happens" to the notorious NSA leaker.
"Snowden has enough information to cause harm to the U.S. government in a single minute than any other person has ever had," Greenwald said in an interview with the Argentinean paper La Nacion. "The U.S. government should be on its knees every day begging that nothing happen to Snowden, because if something does happen to him, all the information will be revealed and it could be its worst nightmare."
It's the most explicit confirmation yet that among the documents Snowden sneaked out of the NSA are some that could harm the U.S. and that these are being used as leverage against the United States as the government seeks his arrest and extradition. It's unclear what actions would trigger such an indiscriminate, mass leak, and who would authorize or execute it.
