John Lattimer's "bulging jacket tests": https://dn710700.ca.archive.org/0/items/nsia-LattimerJohnKDr/nsia-LattimerJohnKDr/Lattimer%20John%20K%20Dr%20109.pdf
And equally important test #2. If the bullet going through Connally was NOT tumbling when it hit him it wouldn't create a jacket bulge. This is because the resulting wound would have been smaller; there would less fragmentation of the ribs that contributed to the bulging. The bulging was not caused solely by the bullet exiting the chest; it was the bullet and the rib fragments exiting Connally's chest that caused it.
One thing I am curious about is what if any lag time there would be between the bullet passing through the jacket and the jacket bulging. Was Lattimer able to determine that. The reason I ask because in other super slow motion footage I've seen of a bullet passing through an object, the bullet exits and the debris it disperses follows behind the bullet. That kind of footage shows thousands of frames per second as opposed to 18 fps, but I think there still might be a lag time of a few frames.
