Well, what would you do if you accidentally send confidential e-mail to everyone. Not as fatal as in the movie American Pie, where the the lead role send a link to his webcam, showing some embarrasing encounter. Maybe the document content is not that confidential, but still the mistake of sending an e-mail should be avoidable. And now you have to live with the embarrasment, the damage is done. No excuse, I'm not Assange nor Snowden, after all.
