Great question. Seems that NSA would have EVERYTHING (quite literally). Huber has justification to request those emails, among other communications. That the servers and mobile devices are destroyed means nothing in a data cloud environment. Fact is, they tried to destroy both public and TOp Secret ( and every classified designation around ) - all in those electronic communications.  We shall soon (next 12 months) get more and more information. Many are demanding arrests (yesterday). That is understandable. That said, this is the largest RICO case in the history of racketeering. The DS is one big racket going back decades, when the C-A was born. We were warned by Eisenhower. With that we know it will take years to unravel the entire criminal cabal, while trying to keep the economy afloat and very active. Some would say that the economy ISthe most important issue. Others want justice, understandably so.  Things are being exposed in a slow-roll fashion so the general public doesn't get spooked. Rightfully so. You don't want to light a match in a crowded movie theater and scream "fire" knowing the result would be catastrophic. Now, if the match was lit and the back row USC engulfed in flames, yelling "fire" would be necessa to save the people and theater.  We have a major fire brewing, for sure. Matches gave gen lit all over that are being snuffed out. Keeping the Public calm is necessary, when you think about it. It's frustrating for those of us who know the crimes that have been committed.
