I wouldn't recommend going down the medical evidence trail at all.
Just know,that one single bullet did not cause all of the tragic damage to JFK's head.It's like a time bomb went off in there & there is no telling just how much of it the Dr.s did during autopsy.
*Of course,I am going off some of the autopsy pictures I have seen with JFK's head completely blasted,and not knowing if they are even real pictures or not and what time that they were actually taken.
