Coming: ‘Last Second in Dallas,’ by Josiah Thompson 

Josiah Thompson was headed for a dull career as a college philosophy professor when he took an interest in the assassination of JFK.

In 1966, he gained access to Abraham Zapruder’s film of the assassination, then under lock and key at the National Archives. By analyzing the film  frame by frame, Thompson became was the first person (outside of the CIA) to forensically analyze the most important piece of evidence in the case of the murdered president. In his classic book, “Six Seconds in Dallas,” Thompson posed–and answered–a question that the Warren Commission studiously avoided: what does Zapruder’s film tell us?

In many ways, the parameters of Thompson’s analysis set the terms for decades of JFK debate. Thompson showed that the Warren Commission’s account did not not reflect what can be seen on the film; that the gunfire that struck to the presidential limousine occurred within six seconds, and that it came from two directions, and The book was a milestone in JFK research, demonstrating that JFK researchers could do more authoritative analysis than the Warren Commission. It was a turning point for Thompson too. He threw over academia and he went on to a long and fascinating career as a private eye in San Francisco, which he recounts in his memoir, Gumshoe. 

Now Thompson is revisiting the JFK story with new findings and thinking about the crime of Dallas. He sequel to “Six Second in Dallas,” titled”Last Second in Dallas,” will be published next November.

At once a historical detective story and a deeply personal narrative by a major figure in the field, Last Second in Dallas captures the drama and sweep of events, detailing government missteps and political bias as well as the junk science, hubris, and controversy that have dogged the investigation from the beginning.

    I also have my take on each frame of the Zapruder film. It actually proves that Oswald did it and, if there is a writer out here who would like to partner up on a last book about the assassination, from what we can actually prove, I’ve got a story for you. Actually, it’s not a story. It’s something that hasn’t appeared in print, on tv, in papers, on discussion boards, or anywhere that I’ve seen. And I’m dying to share it with someone.

  2. Seth Thomas says:

    It is unfortunate that this man’s work, hailed as ground-breaking, is incorrect in so many observations. Six Seconds in Dallas was full of hype and conspiracy hoops. The entire shooting lasted, by using the Zapruder Camera as the standard, from frame 160 (missed shot) to 313 (last shot), approximately 8.35 seconds. Yet incredibly, this time standard may not even be accurate as Zapruder spring-loaded mechanism would only be clocked at 18.3 frames per second when fully wound. We have no way to determine for sure it’s last wind-up.

    Mmmm, seriously Seth? Well I have great news for you. What you have described above seems a reference to something that has been missing from this saga all along, the TRUTH.

    The good news is that if you were to simply spill the beans here about what it is you are so excited about I’m sure you will end up famous.

    For IF, you in fact are sitting on the solution to this puzzle no one will be able to steal the TRUTH from you.

    So let’s have it.

    I agree with Robert. Let’s hear it Seth. Proves Oswald did it? Would love to see that or hear what you have to say because that’s pretty funny. Oswald??

    It’s just a shame that forensics experts never got to examine the limo. That would have been the best evidence of where the shots came from don’t you think. If only we had that evidence now so we could start Case Closed 2 and saved Mr. Posner all the time he wasted on his book trying to prove Oswald did it too.

    Have a great Tuesday and again would love to hear the TRUTH some day but we never will. Very sad.

    Why did oswal d go home to get his pistol? Because he saw right away that he was set up. His help promised for a get away wasn’t there.
