She was careless.
No! She was not careless. You aren't careless when you instruct aides to strip classification headers and send the resulting "document" through insecure fax.
Was she convicted? No. Will she go to jail for it? No. Why? Because Republicans can't get a conviction on anything to save their lives.
That's not the reason why. The reason is because politicians
NEVER go to jail. Sure, they'll talk a tough game, but in the end, they don't want her in jail. It'd set a bad precedent if there was actual accountability.
