"In 2011, a notice to all State employees was sent on Clinton's behalf, which recommended employees avoid conducting State business from personal e-mail accounts due to information security concerns. Clinton stated she did not recall this specific notice, and she did not recall receiving any guidance from State regarding email policies."
That's from the Hill. She also claims that her server was more secure than using a private email service like gmail. What exactly is actionable here? It is guidance, not a law. It was claimed to be more secure (even though it was not).
Your claim that the handling of top secret information is only guidance (not a law), says a lot more than I need to say.
There are numerous criminal codes covering these matters.
