I have never understood why they don’t convert those gas chambers into nitrogen chambers.
Instead of pumping cyanide or whatever the hell else they put into them, why don’t they just pump pure gaseous nitrogen in?
Quick. Painless. Cheap. Environmentally safe (you could probably just open a valve and release it to the environment.
Better yet, just put the criminal’s head into a full face rebreathing device and pump it full of nitrogen. You don’t need to fill an entire room.
