When a person obtains a Security Clearance, mush is determined by the Customer's Security Guidance, but mostly but by the Defense Security Service now days. I have been out of the picture for a couple of years, do stay in contact with my previous peers, and at levels of control from Company Sensitive to Top Secret/SCI/SAP and some above that I dont have comfort in discussing. They almost all include IT information control and transmission, and all that I have ever dealt with have had distribution controls, none that were classified were ever allowed to be transmitted over unsecured means, which included private servers, irregardless of your position in the government. Ms Clinton in my opinion abused her position and her previous role as first lady to abuse this. The SF 312 that I referred to you give intimate detail as what one is responsible for and must do in handling classified material, and the Customer also has rules and guidance, and if properly investigated there no escape, if you did it the penalties are specific. In my opinion, she violated Security rules and should pay the price. Folks used to think that the DoS had separate rules until they hired folks from they old Security Services all old three letter services who were aware of the dangers and the potential leak from DoS channels. Sorry for the length, might be good to put you to sleep.
