I don't even understand why the basic existence of Hillary Clinton's private email system isn't widely viewed as the crime, apart from whether anything was found out by our enemies or whether the Clinton Foundation benefited from Hillary Clinton's tenure as secretary of state.
Honest to God, the existence of the server shows that Hillary Clinton learned the lesson that you can't always count on loyal minions to retrieve information from the wrong hands in order to suppress it by stuffing it down their pants and smuggling it to safe Clintonian hands.
Hence the private server and private email account.
And the loyal minion doesn't seem to have suffered. That's a lesson the Clintons want remembered, too.
