I am not suggesting that Bugliosi was right in concluding that JFK was struck around z210. I was just suggesting that his comments about Lattimer’s theory are persuasive. So it is Bugliosi’s reasoning that JFK was hit around z210 which appears to strain credulity for you.
I'd have to go back to Reclaiming History to find out what Bugliosi had to say about this. I certainly don't agree that JFK was shot at Z210. That is the earliest the WC concluded that Oswald had a clear line of fire at JFK. That is how they concluded the two shots that hit JFK were no more than 5.6 seconds apart. 103 frames / 18.3 comes out to 5.63 seconds. In reality, the shot probably was fired at or about Z220 and struck at or about Z222.
