> Ultimately, there is a line which the US currently hasn't crossed
If US government is killing civilians in various countries and is orchestrating arrests of minors, morally it is not really rising above China by much. Yeah, it is not sending 'guidelines' to the media, because there are other methods of influencing what gets published and what doesn't -- namely intimidation of journalists and sources, appeals to the owners of media corporations and so on.
> Additionally what scares them is the handing out of classified material;
Well what kind of classified material? Yes, if these are nuclear launch codes, or frequency hopping codes of military radios, they would have a valid reason to detect the source of the leak. I think most of us and most US citizens would agree with the government doing that. But these are videos of slaughtering of civilians. At this point, the CIA should be appologizing and not running around arresting and following people. There are now showing their true face (well to the rest of us who didn't know it yet).
> Whatever your feeling on whether it should be classified or not they have an obligation to reasonably mitigate information they consider secret.
That is what I have a problem with -- "an obligation". Obligation to who? Government? Why should we have an obligation to them that trumps our moral sense of right and wrong? Luckily there is someone there, who is an actual human being, with a moral sense, that knows that killing innocent people is wrong no matter how many classification layers get slapped on top of it. That is why these leaks happened. Someone put their job, freedom (and life?) at risk because they felt that the "obligation to hide murder under the carpet" is wrong.
