After more than four decades and scores of books, documentaries, and films on the subject, what more can be said about the assassination of President John F. Kennedy? A great deal, according to the author. This provocative, rigorously researched book presents evidence and compelling arguments that will make you rethink the entire sequence of terrible events on that traumatic day in Dallas. Drawing on his fifteen years of 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. The physics behind lone-gunmen theories is not only wrong, says Chambers, but frankly impossible. This is the first book to: identify the second murder weapon, prove the locations of the assassins, and demonstrate multiple shooters with scientific certainty. It concludes with a persuasive chapter on why this horrible event, now almost half a century old, should still matter to us today. Originally published as a hardcover in 2010, this paperback edition contains a new preface and postscript in which the author addresses some interesting developments since the book was first published as well as the fiftieth anniversary of the assassination. For anyone seeking a fresh understanding of the JFK assassination, this is an indispensable book.
