You said whether it was criminal was up to the DOJ. That's not accurate. Whether to prosecute is up to the DOJ. What she did was criminal.
That's why there are degrees of crimes. What Hilary did was a much graver offense than driving a little over the speed limit. She operated an unsecure email server where she conducted Dept of State business on. Sec State is a serious office. It not like the Sec of interior, or the Sec of transportation. She did so to avoid FOIA requests, because she knew she was going to run for President. All the other reasons they gave were bull shit. You know that and so does everyone else. It wasnt about them not having the device she was used to, whatever device she wanted they would have gotten and set it up however she liked. She was the ******* Sec of State for crying out loud. And because she did that, unknown amounts of classified information were exposed. And it wasnt exposed like Trump and Biden exposed classified. There's a huge difference in documents being in someone's garage or their home and them being on an unsecure server that's connected to the internet. A server that was associated with the Sec of State's email address. Any adversary who wanted to access that server would have been able to at least know where it was on the network.
And they didnt prosecute her precisely because of who she was. Had you or I pulled some shit like she did we'd still be in jail.
That's an objective take on the Hillary BS.
