> Are you saying he now regrets losing his cushy $122k/yr job with Booz Allen, so we can't trust him?

No, I'm saying that I wouldn't be surprised if something happened while he was in Hawaii that inspired him to leave with a bang. Apparently he left the CIA station in Geneva in 2009 because he received a derogatory performance report regarding his behavior and work ethic, and decided to leave prior to the CIA conducting a more thorough investigation.[1] He arrived in Hawaii in March 2012, so he had apparently only been there for a few months before he started stealing documents. He had spent around a year each working systems administration jobs under a contract Dell for the NSA in Japan and the CIA in Maryland prior.

I also don't doubt that he had planned to leak prior to switching over to Booz, since he initially contacted Greenwald about four months prior to taking the job, in addition to the government's claims that he began downloading them all in 2012. But I doubt that it was because he saw something and insisted that it must be brought to light. If that was the case, he wouldn't have walked out with so much data. He claimed to have "carefully evaluated every single document [he] disclosed to ensure that each was legitimately in the public interest"[2], but he took out somewhere between 50 thousand and 1.7 million documents, depending on whose numbers you go by. This is a collection of documents that dozens of reporters, several dedicated solely to NSA reporting, haven't managed to go through over the course of two years, but somehow he himself carefully evaluated the potential damage and public interest value of every single document in less than eight months while simultaneously still working his 9-5 job. I don't buy it. If his intent was to blow the whistle on something, he would have just grabbed the few documents he needed and gone to press with them. The fact that he didn't leads me to believe that he had some other intent.

> "The incident convinced him, Snowden says, that trying to work through the system would lead only to reprisals."

What you left out from the paragraph that quote was pulled from was that it wasn't some shady intelligence operation that apparently convinced him to not work through proper channels, but that he claims was reprimanded for modifying his own performance report in a stunt to prove that there was an issue with the security in one of the systems used by human resources (there's slightly more information in this article: [3]) I don't know the details, but in every place I've worked bypassing security to modify your personnel files would be grounds for losing your job, regardless of what point you were trying to make.

And again, that's just his story - there's no evidence to back it up. Same thing for story about getting the banker drunk in Geneva to recruit him as a CIA asset; and distributing pornographic photos at NSA; and that the NSA took down all internet connectivity in Syria during their civil war; etc. Most importantly, that also goes for his claim that he voiced his concerns through internal channels. When NBC made a FOIA request to verify Snowden's claim that he had raised his concerns, the NSA responded that the only e-mail they could find was asking a generic question about legal authorities mentioned in a training program[4]. If Snowden wanted to maintain credibility at this point, he could have instantly produced the e-mails and said 'Look! The NSA is lying!' Instead, he just made a claim that they were lying without producing any evidence. I find it hard to believe that he walked out the door with thousands upon thousands of documents, but forgot to bring a copy of his own e-mails that would corroborate his story.

I'm sorry - I just think there's way too many aspects of his story that sound a bit too fishy. I could go on about other aspects regarding the NSA reporting, and Snowden's relationship with Glenn Greenwald/Laura Poitras, and questions about why he went to China and how he ended up in Russia, etc., but that diverges a bit from the subject of his grandstanding/credibility and I think that's probably enough for now
