Federal employees are taught about the danger of emails, from not opening suspicious emails on gov't computers to sending confidential information via computer. For example, we could not email patient information to a doctor when we referred them out: We had to send the information by hard copy or to fax it.
Maybe someone should have taught Hillary and her friends about basic computer security...
or maybe even instruct them on basic computer skills, such as how to delete emails when you don't want to keep them on your hard drive.
of course, it's not just Hillary having bad computer security: My federal personnel file is among those hacked by Chinese hackers two years ago.
