Personally, watching the portion of the Zapruder film in which JFK is hit is disturbing to me. So I typically only view it when necessary. This clip does depict some interesting details which I haven’t considered before. It appears to me that at the very beginning of the clip that JFK has his head turned so that he is looking directly at Jackie. Then his head suddenly drops so that he is looking down toward her lap. And he does appear to be trying to say something and appears to be pointing toward his throat with his left index finger. However, with a wound in his trachea below his larynx it is doubtful that he could actually speak. Jackie appears to be trying to see what is wrong with JFK but also appears to have been momentarily distracted by what Connally is saying/doing. Such a sad moment in time and one of the reasons so many of us continue to be interested in the assassination.
