While you are thinking about it it you might ask yourself how does the jacket bulge out but not the shirt or the tie? The tie does not move at all.
Here is the shirt:
Not that much blood there and there would be a less hitting the jacket. Lattimer proved that the bullet itself cannot cause the jacket to bulge.
In my giff of Lattimer's 1994 bulge & flip the tie appears to be short, shorter than the lapel even.
The tie comes out (in 1994), & the end of the tie lifts up to about where we might possibly see it over the top of the side of the jfklimo in the Zapruder 1963 frames/giffs (if the tie came out in 1963).
Anyhow, the tie might have come out in 1963, but it is unlikely that the coming out would be vizible in Zapruder.
I will have a closer look at the 1963 frames to see if there is any hint of tie coming out.
I forget whether Lattimer said that in 1994 the jacket did not bulge nor the lapel flip unless the slug was tumbling during outshoot.
Or whether Lattimer was referring to the lapel flip only.
In any case we can safely assume that the shirt bulges as per the jacket. We can see a bit of shirt bulge in 1994, but i dont think we can see shirt bulge in 1963 (shirt might have bulged, but not vizible in Zapruder)(too blurry etc).
And anyhow why would the movement of the shirt be important?
Its strange that the 1994 lapel on Connally's left side duznt appear to bulge or flip at all.
Lattimer's outshoot in 1994 is much closer to centerline than the outshoot in 1963, & higher. The 1994 outshoot was just a couple of inches from the tie.
In fact the 1994 slug took a big chunk out of the edge of the lapel (as can be seen).
