One of the many significant breakthroughs in The Final Truth is the four-film jiggle analysis triangulation leading back to the source of the shots.  Until this book, the Zapruder film was the only film studied for the jiggle effect.  The Final Truth examines that and four other films— Bell, Hughes, Dorman and Towner— to determine not only the place but the time of that enigmatic first shot.  One of many ‘firsts’ in The Final Truth.
