A number of notable bodies including the Farm Animal Welfare Committee and the EU Food Safety Authority all agree that there is a high probability that the cutting of sensitive tissues at the neck will trigger a significant pain response in a conscious animal

Of course it will. No one is disputing that. What you keep ignoring is the fact that a bolt in the head or a severe electric shock will also trigger a significant pain response. If you doubt that, I suggest you try it out yourself.
