A lot of analogies have been slung around in the months since it came out that Hillary Clinton, while Secretary of State, used a private email server stored in her own home to conduct official business. Most of these analogies have been lacking. Here's one that I think captures what she did:Imagine Hillary instructing her staff that each day they were to take all of the correspondence that landed on her desk, but it in a box and send it to her house. When she finished with it, she threw it in the trash and hoped that no one went through her recycling bin. When it was discovered that Hillary had done this, imagine her excuse was "It was too hard to have correspondence in two places" and "Nothing was marked secret when it landed on my desk. I'm not responsible for what people sent me or how it was classified after I got it."
The point is that this would never have been an issue if her correspondence had stayed at the office where it was supposed to.
