If the US actually has arrested the individual responsible for conveying 'classified' materials that person must be prosecuted. This is true even though the materials were only 'classified' far from 'Secret.' Still it is a truth that most of what any nation 'classifies' is not a threat to society or national survival. Even most of that deemed 'Secret' fall far short of being a threat. Most of what any nation deems 'secret' is not a threat beyond the fact that it is embarrassing. it is very likely that this dump, as with the last two, will not live up to the billing given it a priory by the US. It will turn out to be very embarrassing, but by no means a threat. It has already become obvious that the leak comes from someone who only had access to low-level material which while embarrassing, posed no real threat to anyone but those who would be embarrassed by what they lacked the decency to admit to.
