Dr. Cyril Wecht on the Bullet Wounds to Kennedy's Back/Throat

I've been reading Cyril Wecht's book, The JFK Assassination Dissected: An Analysis by Forensic Pathologist Cyril Wecht, on Kindle this weekend, and it's full of errors. I'll be writing a review in the near future.

Wecht's description of the Kennedy's back/throat wound caught my eye: (page 447 in Kindle)

"I explained how the bullet that hit Kennedy and missed Connally likely continued onward to crack the limo's windshield, leaving a dent on the chrome."

This is the first time I have ever heard this. When I corresponded with Dr. Wecht in the 1970s, he wrote me that he believed the bullet that transited Kennedy exited the limousine on the left side.

I would very much like to see his trajectory diagram to show how the bullet missed Connally but hit the windshield. And where does he think that bullet came from? Of course, he presents no such diagram.

Of course, this confirms Wecht's belief that the bullet wound in Kennedy's throat was one of exit, which is not what Oliver Stone's so-called documentary, JFK Revisited: Through the Looking Glass, claims.
