What a shame it is that attorney Gerald Posner's book, Case Closed (Random House, 1993) is now, in the 30th year after the assassination of President John F. Kennedy, a national best-seller. The book purports to prove that the Warren Report was right: that 24-year old Lee Harvey Oswald was a violence-prone, disgruntled, pro-Communist misfit and loner who, without help from anyone, murdered JFK; that Oswald accomplished the assassination with a bolt-action 6.5 mm Italian rifle manufactured around 1940 and ammunition manufactured in 1944; that shortly afterwards Oswald killed a Dallas policeman, J. D. Tippit, with a pistol; and that the evidence of Oswald's guilt as the lone assassin is so strong that the JFK murder may be described as a closed case.
