My point is that you cannot predict what if any contractions or any other reaction will occur. Not that they don't or cannot. You don't know if they are going to drop like a sack of potatoes or flop like a fish. What I disagree with is the implication that if you shoot them they will pull the trigger. Your previous post summed it up well:
