Would you tell your CEO that he wasn't able to access his email from some unsecure consumer laptop on his private jet?
Yes, because there are laws regarding what you can and more importantly CANNOT do in government that don't apply to the private sector. Besides being potentiality classified, official government emails are official records and have to be treated as such so that us lowly citizens can use the freedom of information requests to see them. Now that she got away with this, what is to stop the head of every government organization from breaking the law and keeping their email on their own servers? Servers they control and can wipe before evidence of other crimes can come to light.
All extremists should be taken out and shot.
