What is the author's tone in the book, Killing Kennedy?

The tone of the book is typically non-partisan. This is a particularly difficult tone to achieve considering the personal opinions of O'Reilly as a political commentator and controversial material in the text. The authors tend to stick to the facts except perhaps when it comes to Lee Harvey Oswald.

There is also an air of fondness in the book relating to the Kennedys - particularly JFK and Jackie. Much of JFK's inappropriate behavior is simply stated as fact and the controversial nature is downplayed. The same can be said of the turbulent relationship between JFK and Krushchev. It is made clear however, that the relationship between LBJ and "The Harvards" was almost hostile. LBJ is painted as somewhat of a ne'er-do-well in the eyes of the Kennedys and is all but ousted from important events. LBJ is also painted as an opportunist.
