Doubt is over
If you ever had a doubt that Lee Harvey Oswald acted alone in the assasination of John Kennedy, as I did, it will be dispelled by reading this book. I actually read the book back in the 90s but wanted to revisit it after discussions with friends about subject. Posner did a masterful work in writing this book. You will learn the facts, just the facts as Joe Friday would say. Conspiracy theorists really aren't concerned with facts, just points to support their theories to sell their books.
