> Name an illegal US activity that was unmasked via the Manning dump.

That was not the point of my post. I did not say or imply that that illegal activities were unmasked by the Manning dump.

I am saying that your prediction that people who think the Manning dump moved democracy forward necessarily believe that basically all secrecy is bad is unhelpful to a conversation about what the whistleblowing laws should be. For instance, some people may think that US foreign policy should all be public while domestic criminal investigations can be private. Some people might believe that the Manning dump was illegal but that some illegal activities (like lunch-counter sit-ins or suffragettes chaining themselves to the White House fence) move democracy forward.
