"Last Second in Dallas reveals new forensic discoveries since 2000 that overturn previously accepted "facts" about the assassination of President John F. Kennedy: that at least some the bullets recovered from the scene were not specifically tied to Lee Harvey Oswald's rifle; that the two-inch forward movement on Zapruder slides Z 312 and Z 313 was an optical illusion, and so the shot in Z 313 came from the grassy knoll; that there were two shots to the President's head that hit in the final second of the assassination; and that the Ramsey Panel's 1982 analysis of acoustic evidence was fundamentally flawed. Together they provide undeniable evidence that JFK was killed in a crossfire. An established figure in the realm of JFK assassination studies, Thompson combines the story of this investigation with numerous personal anecdotes as he walks the reader through his experience of the assassination, his subsequent publications on the event, his lengthy gap in publication on the topic, and his return to the evidence. The work itself focuses on the forensic evidence and does not offer any conspiracy theories or ad hominem attacks. More than 250 photographs, charts, tables, and diagrams support the book's central argument, including the best-quality reproductions of the Zapruder film ever created. Two appendices in the book present scientific analysis conducted by Thompson and acoustics experts Dr. James E. Barger and Richard Mullen"--
