I am against the death penalty across the board, but this article is bad. It makes a lot of claims about nitrogen asphyxiation without citation, and one thing it does cite contradicts what they write.

There's tons of hand wringing about how the prisoner would be an active participant in their execution. By breathing. They spend an awful lot of time on this point, and it's almost silly.

There's some points about how responders would be able to safely enter the room in case of problems. A portable oxygen source with a mask would do.

And then there's this huge misrepresentation for the one scientific study they actually cite:

A group of Swiss researchers conducted research in 2019 on the comparative humanity of nitrogen versus carbon dioxide in euthanizing mice. Their conclusion? That nitrogen did produce a fear response, raising questions about its ethical use as a mouse execution method, and that further studies would be required to determine whether nitrogen would be a suitable euthanasia agent for mice.

Here's the study they cite for it: https://boris.unibe.ch/136198/1/pone.0210818.pdf

Abstract from there: "Carbon dioxide (CO2) is one of the most commonly used gas euthanasia agents in mice, despite reports of aversion and nociception. Inert gases such as nitrogen (N2) may be a via- ble alternative to carbon dioxide. Here we compared behavioural and electrophysiological reactions to CO2 or N2 at either slow fill or rapid fill in C57Bl/6 mice undergoing gas euthana- sia. We found that mice euthanised with CO2 increased locomotor activity compared to baseline, whereas mice exposed to N2 decreased locomotion. Furthermore, mice exposed to CO2 showed significantly more vertical jumps and freezing episodes than mice exposed to N2. We further found that CO2 exposure resulted in increased theta:delta of the EEG, a measure of excitation, whereas the N2 decreased theta:delta. Differences in responses were not oxygen-concentration dependent. Taken together, these results demonstrate that CO2 increases both behavioural and electrophysiological excitation as well as producing a fear response, whereas N2 reduces behavioural activity and central neurological depression and may be less aversive although still produces a fear response. Further studies are required to evaluate N2 as a suitable euthanasia agent for mice."

The tone is completely different. The study thinks N2 would be a good candidate for euthanasia in mice. They do conclude that there is a fear response, but less so. Far from "raising questions about its ethical use as a mouse execution method", the authors think it's worth pursuing as a more humane method.

Again, the death penalty should be abolished. This article is garbage.
