Mr. Paul Landis' description for NBC News of where he found the bullet:
"...on the back of the seat where the cushioning meets the trunk of the car [...] It was just lying where the seam on the back of the seat meets the metal of the trunk, and it's where they would have attached the bubble top if they were putting it on"
A quote from the pre-publication proofs:
“When Mrs. Kennedy finally stood up, I looked down at the seat and saw a bullet on top of the tufted black leather cushioning behind where she had been sitting. It was resting in a seam where the tufted leather padding ended against the car’s metal body. It wasn’t a bullet fragment like the other two pieces. It was a completely intact bullet. It had been hidden behind Mrs. Kennedy all the time she was seated.”
Do the underlined words definitely mean 'behind her side of the [long] seat'?
