What affect would a scream have on the perp? It would seem likely that the scream would cause the perpetrator to strike JB, but would the motivation have been intense fear of being discovered, or would it have been part of a rage syndrome or both? Both anger and fear have similar affects on our nervous systems, but just BR had evidence of rage incidences. If hes swallowed up in a rage, would a quick response just be to grab something to strike her with? The past etiology has it that he would physically attack JB out of anger. JRs anger has been noted by several people as more like seething. Quiet, but scary. OTOH, while it doesnt seem like fear would have affected BR as much in this situation as anger, if JR were the perp, fear of discovery might be the overriding emotional reponse to a scream. What disturbs me - of the many things to disturb one in this case - is why if she screamed, and it were the father of JB, wasnt she immediately released from his grasp and a hand placed over her mouth, and then perhaps she might have been comforted. How big was the fear of discovery? Was it a split second decision that the jig was up and he needed to silence JB before evidence of what was going on in the home were revealed to others? Theres an interesting comment from LW, former housekeeper to the Rs to add to the mix. The comment was made to Peter Boyles and it was that JR was absolutely intolerant of noise. Just throwing spaghetti against the wall, Ive no idea who the perp was.
