Deletion of Mistakes were made

Comment: The NYT article is a solid source.  And here's another good source which features it in the title: ''http://books.google.com/books?id=Q-xxeolg09kC Mistakes were made (but not by me): why we justify foolish beliefs, bad decisions, and hurtful acts''.  This book indicates that we might consider merger into self-justification.  There seem to be many ways to go with this material but they do not require deletion and our |editing policy is not to delete if we can sensibly avoid it
