I love the rosy picture painted of the clean clinical process painted by the advocates of stunning used in our 'traditional' abattoirs. Ignore the exposes into how they ignore even basic animal welfare standards, the fact they can see, hear, smell the fear as they are literally herded towards the stun/bolt.
Ask yourselves if it is so effective why are there guidelines on the best practice for signs of consciousnesses?
At the moment there are differing rules for different animals, horses can't be killed in sight of another horse, pigs can be gassed I'm assuming this is due to them being classed as more sentient?... that looks about to change though and they will soon be as inhumanely disposed of as everything else.
