The 2nd shot was the one that passed through JFK and hit governor Connally. I agree if the 3rd bullet doesn't hit JFK then Oswald will likely fire a 4th shot. I don't think there would be time for any further shots after that though.Which shot was it that hit the Governor? And if he misses JFK with a scope, I imagine he keeps shooting until he gets him or thinks the heat it too high. Guess they would speed away quickly after the first few shots, though.
