If c02 was humane. We would use it on death row inmates.
Quoted from other forums One of the main objections to gas chambers in general is that the person being executed doesn't cooperate (which really shouldn't be a surprise). If the person being executed would breathe normally, or even close to it, the currently used methods are painless and humane. What happens instead is that the victim struggles painfully not to breathe and ends up thrashing around and gasping for breath. I've never watched a gas chamber execution (and have no desire to do so) but from what I've read they are quite gruesome to watch. It's definitely not a quick and painless death in practice.
Carbon monoxide was one of the gases used by the Nazis in WWII. It is currently used in some animal shelters, but there is a push by animal activists to ban gas chambers for animal euthanasia which is causing a decline in their use.
CO2 ??? What inhumane idiot suggested that? Of course the animals go nuts. Their entire respiratory system is telling them that they are dying. They die frantic and in pain. CO is, as the OP suggest the humane gas. Or N2. I can't help but wonder if somewhere down the line somebody with less than useful knowledge in physiology missed the significant distinction.
In all seriousness, I would be wanting a talk with the ethics committee overseeing the research.
There have been threads before on this, and generally N2 seems about as humane as you could get. A gradual increase in concentration over time might avoid the worst issues. Given this is GQ I will grit my teeth and refrain from further comment on executions.

This is me talking now. Again I don't wish to derail or offend. I love chemicals and physics and biology. C02 is cruel.
And there we go comparing apple to oranges last time I check the national veterinary association was not in charge of death row inmates????
Comparing humans to animals in this case just made you lose the very little newbie's credibility you had
