I know this seems like nitpicking, but you said "She went against protocol because she wanted to and she could, and she should own the consequences". The fact is that she did not go against protocol. If the president or congress wanted to prohibit the use of certain communication devices, they would have. Just like if someone's supervisor didn't want them to use a blackberry, they wouldn't write a memo pointing out problems with the device. They would just say "Don't use a blackberry."
The issue is did she break any laws or policies regarding the handling of classified information. That's for the courts to decide. But if there was any evidence I'd imagine they would have brought an indictment by now.
