here is how to up and vanish
The way it works is the livestock comes in single file up a chute and through a vinyl strip curtain onto the kill floor, and there you are with two other guys already waiting in your steel-toe boots and extra plastic bags slipped over your throwaway Goodwill clothes like it’s a makeshift hazmat suit, and you go ahead and use this special gun that’s got a retractable bolt and place it sort of where two imagined lines between the cattle’s ear and opposite eye cross and shape an X-target there where the skull is weakest, and more often than not the retractable bolt does a real good job of it and leaves only a keyhole of a trace, i.e. it scrambles their brains to a real good mess and knocks the living daylights along with any sense of pain right out of them, out of the cattle, who most of them at this point just quiver and buckle and drop down kicking their legs if the bolt didn’t also sever their spine up high at the neck and end their reflexes too…
