Well, this is embarrassing. The NSA is struggling to figure out which of its files Edward Snowden has, reported a government official on Saturday. The former contractor meticulously covered his tracks, either deleting logs that would show what he was up to or bypassing them entirely. Since the logs were put in place to safeguard any sensitive files from being viewed and downloaded by unauthorized parties, the development puts the NSA in an uncomfortable spot. The government has previously assured the public that files in the NSA's database are so closely monitored that they can't be abused.
