The left side of JFK's brain was virtually undamaged as I understand it. The injury was a referred in some quarters a shattering type, partially blowing out the right side and top of the head, apparently. Clearly seen in Zap. This, arguably, explains why Jackie avoided a bloody face-wash.
Look at the facts once more:
1) The plume visible in Z313 at an angle distributed 6 feet above the car clearly shows an incredible and unavoidable mist at the front of his head. The view of her face is blocked by the spray.
2) The car movement forwards would also help scatter this on her face. It is shown in Z313 as a massive cloud which would have had to have distributed itself!
3) The reports of motorcycle policemen passing behind on Jacqueline's side also reported being struck with body tissue (6 to 8 feet away)
4) Jacqueline's distance a mere 12 to 18 inch distance without even a flinch in the film sequence just following Z313 pretty much dismisses a right side blowout coming from the TBSD (up and behind) and staying on his side of the car! Her face was facing his direction too!
5) She has no reaction until after Z329/Z330 upon which time she notices something very much has happened and that unusually matches the red blur masking the President's entire head! As I said earlier, JFK's face goes from white to that of dark red. (Just after you see the massive windshield glass shatter reflected in the light. Clint Hill is in ducking motion and out of way by Z322 to avoid being hit.
6) The mere fact that JFK goes back in his seat and raises his right arm is too coincidental with Clint Hill ducking and going forward at the very same instant. If there was hard braking of vehicle, you could say Clint Hill lurched forward as a result. However that motion is exact opposite to a supposed limp Kennedy's reaction. Weakened by an earlier visible neck shot when he stops wavings and places his hands near his neck, he reacts in the exact opposite Clint Hill!
Bullets from the front explain rather nicely why Jackie avoided a bloody face-wash, please and thank you! You would be foolish to think that an explosive round such as that exhibited in Z313/Z314 complete with a lingering mist in those frames could miss Jacqueline's face. There was lack of expression change just after Z313 as well but before Z329 indicating nothing has changed other than her trying to figure out where he was injured in the neck shot. Could we not draw a conclusion that inbound bullets never occurred there? Remember that is evidence only required to frame LHO and make it look like the shots came from behind!
You can't help but see the expression change in Z335 when she decides to leave the car - wondering if she is going to survive! Her clean face
with eyes getting very large and in shock - no indication of splatter and there are some very clear Zapruder frames in this area. Look closely at Z335 and you can see Jacqueline's left shoulder in the frame, see the position of Kennedy's ear and absolutely nothing in front of it. It sure looks like an edited picture to me! His head is cut off! Kind of a "wet" gold nugget (sunlight reflection of course) below Jacqueline's clearly visible shoulder. If that frame wasn't edited, Kennedy had no head at all from the ear forward to try to save at hospital or to even take a picture at a morgue. It was edited out of the picture obviously as you can't reconstruct that big of a mess and end up with a head later on for a funeral! That was a rather serious edit on that particular frame!
You couple that with the man coming from the front of the car (some would like to call him Macolm Summers) having his head totally scratched out of the frame on Lightbox Z347 (intentionally obliterated???) leads a conspiracist to question that maybe this man who rolls into the grass has more to do with a windshield shot than meets the eye and is a key character in the assassination scene! At frames z363 the family with the small child remains virtually
motionless and emotionless - that is unexplained! Why is there only one massive reaction (movement done by one guy rolling across from the front of the car - my assumption) while everyone else close remains motionless in the pictures? You would have thought the next couple with the child would have some reaction after hearing gun shots and seeing a man rolling in the grass. Wouldn't the child be covering his face in horror? Instead no responses. They missed looking over and seeing the guy beside them running and rolling?
Again, Kennedy's hand and head movement is extremely meaningful if he is reacting to something he saw at the front of the limousine. Who would think that a shot taking out his entire front of head at Z313 would cause his head to move back in the seat (about a foot) against the bullet flow and at the same time causing him to raise his right arm up. That looks like a pure defensive move to me! Tie it together and you have a very close frontal shot, no splatter on any occupant's in the car and a dead President! No one else hurt!
Of course, no eye witnesses observed or ever recorded that very obvious head movement and arm lifting visible in the Zapruder Frames! Maybe it was all masked by the cloud of misty vapor? I would guess it was a well executed script to thwart out the possibility of having to deal with more than just one lone gunman who was killed before he could talk and proclaim his innocence. Yes, it had to be a deranged nut with no motive at all!
