Humane Killing

I wonder what took so long but someone finally invented a humane shellfish killing machine. You may ask why but apparently there are places with laws requiring humane killing of animals including crabs, lobsters, and crayfish. The inventor of this machine happens to be a lawyer. So I guess suing or defending inhumane shellfish killers in court weren't bring in enough money for him. I wonder which is more humane, humane killing by such a machine or death due to natural causes. By the way, I also wonder if humane killing some how make the shellfish tastes better. I doubt it since if it was the case the maker of the killing machine would be jumping all over that. Afterall, taste better is a much better marketing point than humane.
