What more can be said about the assassination of President John F. Kennedy? A great deal, according to this author, a physicist and ballistics expert. Drawing on his fifteen years experience as an experimental physicist for the US Navy, the author demonstrates that the commonly accepted view of the assassination is fundamentally flawed from a scientific perspective. He claims that the physics behind lone-gunmen theories is not only wrong, but impossible. The author devotes separate chapters to the Warren Commission, challenges to the single-bullet theory, the witnesses, how science arrives at the truth, the medical and acoustic evidence, the Zapruder film, and evidence for at least a second rifleman in Dealey Plaza.
