There are conflicting reports about the blow: some say it came before, some say it was almost simultaneous, some say it came way before, some say after. Also, we don't know definitively what caused the blow (you say flashlight, but again, that isn't definitive). I know the CBS special made people believe that a nine year old could have caused enough damage to cause the blow, but that's unrealistic in my view. JBR was not perfectly stationary and this was a real human being; not some fake skull and wax like they used in the television program. I don't see how the pineapple has anything to do with it one way or the other. They all distanced themselves from it. In my view, they forgot to dispose of it in all the chaos that night; or they weren't smart enough to realize it would be found in her digestive tract, and just left it out.
