Earlier quoted context omitted.
The e-mails should have put her in prison, and they would have put anyone else in the same situation in prison. But you're right, with her being her, they're a complete nonissue. They simply don't matter at all.
To be absolutely objective about it, there really are people in prison for doing with confidential state secrets what Secretary Clinton did with confidential state secrets. [1] http://www.politico.com/story/2016/05/kristian-saucier-inves...
1) Saucier generated the classified information. He took the photos. I don't think there was evidence the Clinton was knowingly sending classified information to non-cleared individuals
2) Saucier himself deleted the files from his laptop after learning he was under investigation. The FBI in Clinton's case determined that there was no willful attempt to obstruct justice
3) The quantity and quality of the information likely differs. If the Clinton emails contained photographs of classified military hardware, we'd probably see more motion.
See Comey's quote comparing the Petraeus case to the Clinton case:
"So you have obstruction of justice, you have intentional misconduct and a vast quantity of information," Comey said. "He admitted he knew that was the wrong thing to do. That is a perfect illustration of the kind of cases that get prosecuted."
