Care, YOU want to suddely declare ONLY SECRET and TS-level information can be looked at. It doesn't work that way. YOU don't get to make that call.
Confidential, SECRET, TOP SECRET, and Special Compartmetalized Information -- 'SCI' - material is involved, and she has broken laws regarding them all.
If you have TS/SCI information on a server, that server is therefor classified as a TS/SCI server. ANYTHING on that server is then classified as TS/SCI...even if it is un-classified personal material. By law you can not save /send multiple levels of classified documents on one server.
The military, for example, has different colored stickers on their PCs labeling them as UNCLASS, SECRET, and TS. Among the many laws she violated, she broke the law by putting it all on one server and sending different classification-level e-mails from one server.
When you KNOW what you're talking about, when you KNOW what the laws, regs, and rules are pertaining to Classified, and then start disecting Hillary's actions as they pertain to the access to, handling of, and destruction of classified information you begin to understand the mountain of violations and crimes with which the FBI will be able to charge Hillary if they do choose to do so.
