As an aside, I would urge caution in putting the bullet impact too late. A strike at z224, or even z223, opens the door up to CTers to go to their standard claim “The reactions are too fast to be humanly possible”. Popular for both the z222 and the z312 bullet strike. They would make the same claim about a third strike on the President or the Governor if we LNers believed there was a third strike. Frame 222 is the best estimate. I’m not placing it earlier than it should be, except a CTer might point out that z222 is 110 milliseconds before z224, not 100. Even so, Frame 222 is the best estimate we have, subject to future testing of the nature Dr. Lattimer carried out.
Hi Joe,
The way I'see it at the moment is that the argument for an impact earlier than z224 is the preceding frame in which Connally is sat looking completely untroubled.
The Croft photo can be fairly accurately synchronised with z160, give or take a few frames. In it we see Connally looking towards his wife, Nellie. If we roll the Zfilm forward from this point and focus on Connally we can just about make out him looking towards his left then turning his head to the right. He stays in this position as he passes behind the Stemmons sign. As he emerges from behind the sign the first good look at him is z223 in which he looks totally calm and composed and his jacket hasn't started to bulge. It seems clear to me he has not been shot. In z224 we see the right-hand side of his jacket beginning to bulge, this is the shot which passed through both men. z225 the beginning of JFK's 'hand snap' reflex, z226 both men begin to react to being shot.
Because I'm so green here I'm not sure what a CTer or a LNer is or what they think, I can only make my judgement off what I'm actually seeing and will only listen to arguments that I find compelling (the Larsen/Graves identification of Gloria Calvery being a good example).
