I don't feel like there's really any excuse to use a personal email server as your primary means of correspondence when serving as Secretary of State. I just think it reflects a level of professional incompetence more than a criminal offense.
i can see where you're coming from, and while i can also see why it shouldn't be considered a criminal offense, but the level of incompetence oin the handling of classified information is still pretty off-putting to me, and again, there can also be reasons why the FBI aren't indicting her right away
and also in a response to your post i missed;
They recovered all of the emails though. Outside of loony conspiracy theories, there's no reason why the FBI wouldn't indict her if they found that she was throwing out classified or top-secret information.
i'm hoping this doesn't sound too loony to you guys, but this is a post online that i found that pretty nicely summed up what i thought in better words than my own;
The way I understand it is the FBI is wary to recommend the DoJ to prosecute because it's simply that sensitive of a matter. The full extent of the Clinton Foundation/e-mail server being compromised would come to light and implicate too many powerful people. They don't want to indict the presumptive Democratic nominee of treason (that is for leaking secret access programs and compromising field agents).
go on wikileaks. most of that stuff is so inconsequential its not even interesting.
these are 50,547 pages of documents, i'm not sure if you looked through all them and just got 'meaningless garbage', and there's also still the unrevealed e-mails/documents that are kept from public viewing/hearing for a reason
