Ford's Theatre
During the book's initial release, Rae Emerson, the deputy superintendent of Ford's Theatre National Historic Site, conducted a review of the book's text and discovered a number of inaccuracies, which she described as "factual errors" and listed as numbering ten, each different and one additionally occurring multiple times. As a result of the review, the National Park Service, which manages Ford's Theatre, made the decision not to allow the edition of the book containing the errors to be sold at the Eastern National Bookstore located in the Museum at Ford's Theatre National Historic Site, although it is sold in a gift shop in the lobby that is operated independently by the Ford's Theatre Society. Historian Edward Steers has also criticized the book in a review for various inaccuracies and for lending support to conspiracy theories.
