It's also very disappointing that, for quite some time, Snowden was labeled a "traitor". Even now, although the polls are showing that the majority of Americans surveyed state he is a whistleblower and not a traitor, that what he did was bad for, or an action against, America.
If what Snowden has said is true regarding the level of access he had when working in the CIA, then it is absolute proof, if any more is ever needed, that his actions were taken in the interest of the public and not himself, and especially not against America.
It's likewise very disappointing how little has come about as a result of what was shown by his leaks through the Guardian.
