First of all, i'm not on the fox news bandwagon. Secondly, the documents were stolen, which is a crime. Believe it or not, in order for a government to function, especially in terms of national security and wartime, it cannot be 100% transparent to the entire world. This would be like asking poker players to play a game of high stakes poker with an open hand. It doesn't work, period. These communication documents contained the same kind of sensitive information that should not fall into the hands of extremists. Granted, there were many other documents that showed crimes and torture that should have come to light, but not at the expensive of released every document.
If you think 100% transparency would work, then you obviously have no idea what national security means. If you have such a bleeding heart for those being mistreated by government, then you're probably liberally blinded to the realities of modern governance.
