When it comes to the cloud over Hillary Clinton’s emails, a natural question would ask, “What was she thinking?”
In light of serious Wikileaks involving other diplomatic matters, I wouldn’t be surprised if she feared the official site would be compromised, targeted, already hacked, or simply betrayed by a disgruntled employee. Confidentiality, like it or not, is part of international diplomatic maneuvering.
Hillary learned early that not even the White House was safe from intrusions by the likes of Rush Limbaugh, who somehow left notes on the guest room pillows.
You’re not paranoid if there’s a reasonable expectation of attack. Had somebody suggested to her to go another route? It could have been viewed as prudent, perhaps.
Just a hunch. We’ll see.

A bit off topic, but I scratch my head over the fact that people can approve of both Wikileaks and privacy.
Looks to my like the heart of the dilemma. Or are we just back to “not in my backyard”?
