Snowden sought Booz Allen job to gather evidence on NSA surveillance

In college I had a friend who wanted to intern with the NSA. He was extremely smart, knew his way around a computer and then some, and was a model student. He was one of the few classmates of mine who never smoked and only occasionally drank, and even then only in moderation. He was exactly the sort of person who you'd expect to get the job (well, internship) with the NSA.
Following some initial interviews, he went for a polygraph at a facility near campus. Then, he was called to the DC area to undergo more interviews and another polygraph. Finally, he was called back for a third polygraph...and didn't get the job.
My impression at the time was that the NSA was doing such a thorough job screening candidates that they were likely discarding a large number of false positives from their screenings. This changes that impression completely...
What's worse than a government agency that has access to all of your secret information? A government agency that has access to all of your secret information and can't even determine if the people it's hiring and giving access to that information are trustworthy.
Not good...
But why does this not increase Snowden's credibility? He went undercover to gather evidence of malfeasance. How does that not turn him from a leaker into an investigative journalist getting an inside scoop?
Like the GP post said, the intentions or motivations (emotional or intellectual) are of little concern as long as the scientist changes their views/theories based on experimentation. I could be emotionally invested in what I believe to be a life-saving cure for cancer, and I'll be emotionally pre-disposed to see the medical trials prove that, but that won't mean I'll fix the results to prove that.
