"Seriously, if this is true..."
It's extremely unlikely this is true. Think about it...
He's a sysadmin at the NSA, which means he's supposed to be maintaining their servers -- not looking through classified materials. So if he were to report to his superiors about his concerns with any of these highly classified programs, he'd be admitting to looking at information he should never touch. If he did anyway, he would have been shit-canned immediately and investigated. So, it sounds like a complete pile of horseshit to me.
Either way, this kind of issues should roll uphill, not downhill. If the people in charge can let a Snowden slip, how many more have they let? How many more will they? Someone is trying to avoid their responsibility.
The fact that Snowden was able to get out with the info, suggests the thing is mismanaged. Why was he given access to all this super-classified information, and who's responsible? What was a contractor doing in a super-classified government organization anyway? What Snowden managed to prove, either from the leaked content, or from the fact that there was a leak, is that no one is watching the watchers.
It doesn't matter how you look at it, in the end, it's a complete management screw-up.
