I don't know but I'm very suspicious of him.
First off, he went to hong kong (which is controlled by our number one enemy in the cyberterrorism and hacking field, China) for sanctuary due to their...how did he put it..."support of free speech"? Hong kong may be a little bit better off than the rest of china but free speech does not exist truly in ANY area of a communist dictatorship.
Second, he seeks asylum in Russia (another nation that has the potential to gain a significant advantage should he sell information to them) which also has a terribly low amount of free speech. Whether Russia calls itself a democracy or not, Putin is a dictator and human scum in general and free speech can never exist in a country such as that.
Finally he seeks asylum in Ecuador which is, by history, fairly unfriendly with the United States.
It's like he's choosing countries that have a lot to gain from info against us instead of countries that just promote free speech. Besides instead of using the proper routes to report any malpractice he's jeopardized what could have been an important counter-terrorism operation (which everyone now knows about and can create countermeasures for).
But let's ignore this for a second. If he really is an innocent whistleblower, why would he not even attempt to report this supposed malpractice through proper channels? He was too scared? Of what, if the proper channels were used the NSA wouldn't even know he was reporting just that there was an investigation (government departments tend to be competitive and loathe to share information with each other for reasons unknown to humans...ps they aren't human).
If I had any say on it though, whether he's innocent or not I personally want him dead. He knows way too much to live outside our nation's borders and I'd rather have him dead (innocent or not) than have any of our nation's info in the hands of a threat like China or Russia. Once the external threat is dealt with I can start worrying about the internal ones of whether NSA really did anything wrong or not.
