I'd be interested to see what you would do had you been in such a position. Getting fired from a government position is a bigger deal than you think, especially if you have a family to support.
I am not discounting it. But it is an equation: The questionable benefit of learning e.g. some publicly available datapoint pales in comparison to the damage to our nation. This isn't some banana republic. Why do you accept that it is? This isn't Turkey, thank God.
Executive is doing something illegal? Take them to court!
Why get fired? Why not send it to wikileaks? Why not pick up the phone and contact NYTimes? Heck, there are legions of representatives in congress and senate who would love to talk to you and give you immunity to boot!
These people -- /whoever they are/ -- are creating the perception of alternative governmental outlets. No one who cares about this nation would do that.
