I call Bullshit. Breaking the law does NOT require intent before you can be charged.
"Honestly, officer, I didn't MEAN to speed. I just wasn't paying attention."
"But I didn't MEAN to kill that other hunter. I just shot at the sound and didn't know what was in the bushes."
"I didn't MEAN to run that stop sign. I didn't see it because I was busy playing with my cell phone."
If intent was part of the prosecution then there wouldn't be a need for the saying "Ignorance of the law is no defense." You can still be charged and prosecuted for breaking a law even if you didn't KNOW it was illegal.
Disclosing classified material, which she should have known was classified, is breaking the law. If I did that when I was in charge of classified information it would have gotten me arrested, my security clearance revoked, and my job changed. I would never be allowed to handle classified material again.
Instead the FBI says "Oh, let's not prosecute her because she didn't MEAN to reveal classified material over an illegal, unsecured email system.
The more likely reason they decided not to prosecute was that they didn't want to draw attention to the fact that multiple classified email messages were sent over an unsecured system and are possibly stored in the backup systems of the commercial email servers. Sweep it under the rug, deny there was any wrongdoing, and hope nobody remembers it once the election circus starts.
