Those are personal emails that several lawyers agreed were just personal, brainwashed functional moron. You people start with the fact that Hillary was a criminal though you have absolutely no evidence.They were erased and she was covered by the FBI.Maybe, just maybe they can investigate Benghazi again...
But, but what about Hillary's emails?
In that particular case, she put herself in the situation where suspicion was inevitable by deliberately mixing business and personal emails, I believe to give her cover to delete stuff she didn't want to come out. There would be no controversy had she simply used the government provided hardware and software for all government emails. That way, there's no deleting anything. But she did not.
