Ask HN: Why help, or protect WikiLeaks?

I find my self really pissed off at the general lack of support for freedom of information, and can see my self getting involved somehow, but before I do anything I want to make sure that I am informed.

I imagine there has been a line of discourse over the years about the idea of leaking state secrets when there is a believed greater good. Does someone know a way to get a primer on this line of discourse.

What are the preeminent arguments in this space, books, papers, people?
