Very detailed description of what we are seeing. But by Golly somehow You Forgot to mention that even though Connally had his Radius Bone Busted along with the Tendon Severed that controls his thumb, he Still somehow managed to maintain his Grip and Hold Onto that stetson hat of his. Strange how You Forgot to include this in your narrative.
Repeating what you read/see on the internet isn't evidence and as Jerry points out, you don't have a clue.
What happened Royell, you were so much better than this?
But anyway Connally's wrist wound can tell us a lot. Firstly the amount of lead in the wrist is tiny and as Lattimer shows us, the approx equivalent amount of missing lead from CE399 is enough to make many tiny lead fragments.
And next we see the WC results of a full on bullet strike on a human wrist and we see massive damage whereas Connally's light fracture indicates a bullet that has been dramatically slowed.
