Oklahoma governor signs bill allowing nitrogen gas executions

[AFTT47]

I'm 100% against the death penalty but I've often wondered why this method was not used by states who insist on murdering the murders. I'm familiar with the physiological effect because of my background as a scuba instructor. Zebo is correct in that it is the build-up of CO2 which causes a feeling of air starvation, not a lack of oxygen. All you have to do is replace the oxygen one breaths with an inert gas such as nitrogen. They won't notice a thing until the oxygen percentage drops below about 16%. At that point, they'll simply get light-headed and lose consciousness. No discomfort at all.
