Since starting Libra, all I can think about is the musical by Stephen Sondheim, "Assassins," which tells the stories of the people who both succeeded and failed in assassinating a president. Each of the assassins stories, called ballads, are narrated/sung by a balladeer, who later is revealed to be Lee Harvey Oswald. In the song, "Take a Look, Lee" the ghosts or spirits or whatever of previous and future presidential assassins convince Lee to kill JFK instead of taking is own life. They tell how his name will leave on for years and years, and how he helps them live again. Together, they create history.
You know, it is an interesting theory to think about. The spirits of assassins led Lee to commit murder. Fits right in with all the other theories. However, it does kind of reinforce the idea that Lee was nothing more than a crazed crackpot. Yet, the lines of "Take a Look, Lee" are really powerful. I mean, the assassins aren't wrong. Sometimes the names that live in infamy live longer than the ones that once reveled in fame. It's true that Lee will live on forever, and become a part of history along with John Wilkes Booth and Leon Czolgosz and Charles Guiteau and yes, even John Hinckley. Indeed, Lee, through killing JFK, shapes history more than he thinks. JFK becomes a president forever immortalized as a great man who did wonderful things for his country. Almost all negative views of him are pushed away, such as how any negative views of Abraham Lincoln were wiped away when he was assassinated by Booth. The assassination changes people's perceptions of their presidents, and we can see, from "Something Just Broke," that that perception will have a lasting impact on the entire country.
