You have to look at the geometry of that limousine to see that there was nothing magic about that bullet. It was all in a straight line. The hustlers selling books and movies don’t want you to know that. .
And the “pristine” bullet found at Parkland?
“It entered Kennedy upper back, exited his throat”
Then why the ‘splody head?
