Hillary Clinton told aid to send secure info through nonsecure system with no identifying heading

Game changer...

Clinton, the front-runner for the Democratic presidential nomination, has repeatedly maintained that she did not send or receive classified material on her personal account. The State Department claims none of the emails now marked classified were labled as such at the time they were sent.
However, one email thread from June 2011 appears to include Clinton telling her top adviser Jake Sullivan to send secure information through insecure means.
In response to Clinton's request for a set of since-redacted talking points, Sullivan writes, "They say they've had issues sending secure fax. They're working on it." Clinton responds "If they can't, turn into nonpaper [with] no identifying heading and send nonsecure."

I don't see how Hillary avoids an indictment after this revelation.
