> So far it seems no-one who has leaked information has had the clearance to get to the truly painful stuff, but the psychological screening to get to those levels is specifically designed to keep potential Snowdens and Mannings out. This implies that the reason nobody has leaked such things is because it's too high in the security clearance hierarchy and therefore nobody of good conscious has been near it. The reality is much more likely to be a result of compartmentalization rather than "making it high enough security clearance" such that few can reach it - as if getting higher security clearance grants you access to more and more information. Even at the highest levels of clearance, you can only see what it is deemed necessary for you to see.
