Just because Hillary Clinton wasn't using work email as Secretary of State doesn't mean she was throwing caution to the wind -- if anything, she may have been shrewder than most. The Associated Press has learned that Clinton conducted official business using an email server registered to her home. It's not clear exactly where the server was or who ran it until 2013 (probably not internet 'inventor' Al Gore), but the move gave the politician a lot of control. Since the email was strictly hers, she could decide if and when she turned over messages to the government or lawyers. It may have also let her toughen up security versus off-the-shelf services. If the server was in her house, she would have even had the Secret Service offering physical protection.
