For the longest time, US officials denied that Edward Snowden made serious attempts to raise concerns about NSA surveillance activities before he took off with classified data. There was only evidence of one not-so-worrisome email, they said. However, it's now clear that this isn't the whole story. Documents obtained by Vice News (and published by the NSA) show that Snowden likely did more to raise concerns with the NSA than officials claimed. While there's no smoking gun, two out of three previously unmentioned Snowden interactions with the Oversight and Compliance Office involved disputes over an open-book test on foreign intelligence gathering. The findings suggest that Snowden might have disagreed with the test's interpretation of the law, which would be in sync with the previously released email.
