So I went a little further by reading parts of the actual regulations, i.e., the implementation and enforcement of the act, because I’m genuinely curious to learn about this. It seems that they’re defining stunning as basically destroying the brain of the animal before killing the body. For instance: “Unconsciousness is produced immediately by physical brain destruction and a combination of changes in intracranial pressure and acceleration concussion.” It seems like a distinction without a difference, since they’re essentially killing the animal by “stunning” it or making it “unconscious”.
