Hillary requested a book on e-mailing that includes tips on how to delete messages for good

Clinton has not said why she requested the book, but it includes some advice that is particularly interesting in light of the controversy over her unconventional email arrangement at the State Department and her decision to delete tens of thousands of emails she deemed to be purely personal.

The copy that ABC downloaded for $9.99 had some interesting revelations.

Take, for example, Chapter Six: “The Email That Can Land You In Jail.” The chapter includes a section entitled “How to Delete Something So It Stays Deleted.”

“Some people are hoarders, some are checkers,” the authors write. “The main thing to consider is that once you do decide to delete, it’s like taking the garbage from your kitchen and putting it in your hallway. It’s still there.”
