I've had a number of discussions with Jenkins, and can say it is a mistake to think he's just telling CT's what they want to hear.
1. He has long insisted he was present from the beginning of the autopsy, and that the pre-autopsy surgery proposed by Horne did not happen.
2. He has long insisted the back of the head at and below the level of the ears was present, but shattered, at the beginning of the autopsy. This is a problem for CTs, such as Mantik, who insist the Harper fragment was occipital bone, and that the low back of the head was missing both at Parkland and Bethesda.
