What is the importance of "Camelot" in the book, Killing Kennedy?

Camelot is a mythical place in literature and the home of King Arthur and the Knights of the Round Table. After JFK, Jackie and the children took up residence in the White House, people began to refer to it, and to the Kennedy reign as Camelot because it seemed to be an idyllic state. The Kennedys were wealthy, powerful, beautiful and stylish. They represented what every American family hoped they could be. Inside the walls of Camelot, things were not so idyllic but the Kennedys were so well loved that even the media did not dare to tarnish their image.
