Ok, but you still need to distinguish between Snowden and the historical cases of civil disobedience where thinkers have agreed that submission to punishment was necessary for justification. Simply pointing to some revolutionaries which are commonly accepted by the public as justified is not enough. You need to engage the argument of MLK, Rawls, Gandhi, or whoever.

Would they have agreed that the revolutionaries were justified? Is Snowden closer to the revolutionaries, or to repressed blacks in 1963 Alambama?
