Sorry, Paul, but do not impose your limitations onto others.  It has been clearly stated in the media and by the intelligence agencies that it was not sophisticated hacking that "liberated" the democratic emails.  It was simple phishing wherein an uninformed user reveals their own log-in credentials by a trick email.  If electronic records have been kept it is possible to identify the phisher, but the intelligence agencies make no representation that they were able to access appropriate electronic records which may only be on foreign machines to which they have no access.  But if you wish to follow those you view as experts, that is your choice.  I question everything.
