"All this evidence fits with Tague being hit by a fragment from one of the shots - the second shot, according to Tague's WC testimony."
Isn't your second shot the one that was supposed to exit JBC's chest while he was facing Zapruder?
How could a fragment from such a shot head towards Tague?
The deflection is off the wrist that is pressed against the chest. The bullet sent a spray of lead throughout the wrist wound after striking and shattering the radius well above the wrist joint.
No one has ever been able to explain how the bullet and its resulting fragments would not obey the laws of physics and deflect away from the point of contact. So
if the bullet obeyed the laws of physics, it should have deflected up slightly. The fragments that struck the windshield were spread over an area of about 12" x 12" ranging from the upper edge down to below the mirror.
