The article "Dealey Plaza Echo" is a journal featuring various articles on the assassination of John F. Kennedy. The first article pays tribute to Jack D. White, a pioneer in assassination research who contributed significantly to advancing the case, highlighting his photographic work. The second article explores the role of Lillian Rogers, the secretary and personal assistant to Abraham Zapruder, who was instrumental in encouraging Zapruder to retrieve his camera on the day of the assassination. The third article, "Harvey, Lee and Tippit," raises questions regarding the shooting of Officer J.D. Tippit and examines evidence suggesting that Lee Harvey Oswald was not the sole suspect. The fourth article, "The Single Bullet - Fired by the Mafia?", uses a diagram to argue that the single bullet theory (SET) does not support Oswald's guilt and suggests the possibility of mafia involvement.
