There are another couple of points that are relevant, but I don't know if they're any good in trying to explain things.
The method we're talking about, which is the stunning and then chucking and then bleeding, are consistent with abattoir practices that are used worldwide. They use stun guns to cause irreversible unconsciousness, followed by death. So that's consistent with abattoir practices.
As well, one of the references we referred to in our report is the 2000 panel on euthanasia, which was created by the American Veterinary Medical Association. It's the standard that's used worldwide for methods of euthanasia in all different species of animals. It says that physical methods such as a blow to the head can be humane in an animal with a thin cranium, like a young pig, which is the example they use.
So these are consistent with scientific standards, but there's still the whole matter of, as you say, public perception.
