Bill, you are a conspiracy theorist! You need to be a realist. The x-rays and the autopsy pictures are the ones used by the HSCA.
"Dr. G. M. McDonnel oversaw the production of computer enhanced copies of the original skull x-rays for the HSCA, and then copies of these copies were made available and released by NARA. Dr. McDonnel?s interesting past and his interpretation of these x-rays will be discussed later."http://assassinationofjfk.net/a-review-of-the-jfk-cranial-x-rays-and-photographs/I do agree that there is what seems to be a patch in the x-rays in the right rear of the skull, but there is no way that could be an exit wound from a bullet that entered from the front.
