But in this landmark book, reissued with a new afterword for the 40th anniversary of the assassination, Gerald Posner examines all of the available evidence and reaches the only possible conclusion: Lee Harvey Oswald acted alone. There was no second gunman on the grassy knoll. The CIA was not involved.
