Sentenced to death Part 1 The Captive Bolt Pistol does not cause instant death. It is a method of stunning that -- if used correctly -- stuns the animal, so that the heart carries on pumping after they have had their throats cut. However, this can and does fail -- leaving some animals fully or semi conscious and in pain whilst they are bleeding to death. Part 2 The video makes clear that the festival footage was taken in France. However, in the UK slaughter without pre-stunning is only legal for so-called religious slaughter -- and it happens here to thousands of animals every year.
