Computer experts will explain that electronic records never actually disappear. In this case, there are lots of sloppy and greedy people involved---what one might attempt to destroy, another may still have. In the end, truth will out. Watch events in Egypt carefully--el Sisi must have LOTS of info, particularly email and other traffic American players thought was hidden, because it was sent in Arabic. I am guessing, not so much, and that NUMEROUS "folks" hacked the servers in DC, Chappaqua, as well as accounts of Teneo, Clinton Foundations. Moreover, there likely are many alias accounts (think Richard Windsor). Stay tuned.
