"There was no indication that the information in Kerry's email was considered classified at any level at the time it was sent or if Kerry, then chairman of the Senate Foreign Relations Committee, would have considered it particularly sensitive"
http://www.politico.com/story/2015/09/hillary-clinton-email-state-department-release-214246 " The messages are from January 21 and 22, 2011 and were forwarded to Clinton's private account by Deputy Chief of Staff Jake Sullivan"..."A State Department spokesman said that message, and the others deemed classified, were not marked as such when they were sent to Sullivan by other State officials." (so in other words, Sullivan was sent the message on unclassified systems and he simply forwarded to his boss, which means it was not Sullivan's or Clinton's fault, and is just the spread of a data spill event)
"The other message deemed "SECRET" in Wednesday's release is only classified in a technical sense."..."It appears Abedin, now the vice chairwoman of Clinton's campaign, got the transcript from State officials who downloaded it off the Internet and were debating how to respond to the leak." (In other words, the classified document was on the internet, yep, somehow that is Hilary's fault according to you).
"As has been reported on multiple occasions, any released emails deemed classified by the administration have been done so after the fact, and not at the time they were transmitted"
I could keep on going on and on and on, but so far, there has been nothing that I have seen which has said the emails that have been deemed to contain classified information were generated or created by Hilary and/or can be attributed to a fault that she caused.
