This is stupid. Everyone knows it will get struck down by the courts for whatever stupid liberal reasons they can come up with. These types of controversies are just kept up by the political class to keep everyone riled up about something that is of no real consequence.
If you want to have executions, it is so brain dead simple to set up that even a liberal could do it.
1. Build an airtight enclosure.
2. Wheel the condemned into the enclosure strapped down on a gurney.
3. Pump the enclosure with pure nitrogen. Put oxygen sensors both inside and outside of the enclosure.
4. Wait 15 minutes.
5. Vent the enclosure to the roof of whatever building you are in while cycling in ambient air.
This is no-muss no-fuss execution. The condemned won’t even know he’s dead when he passes. 78% of every breath you take is nitrogen. There are no unusual chemicals, poisons, or anything else to get people riled up over. No doctors must violate their hippocratic oaths.
Every industry that deals with nitrogen in any volume understands the safety requirements you have to put in place so that people do not enter a pure nitrogen atmosphere. A person in such a situation will simply collapse and die without warning because nitrogen saturation does not trigger an asphyxiation response in the body.
Some will doubtless complain that the condemned will not suffer, and while that is true, it is also true that he will definitely be quite and fully dead, which I figure is the point of the exercise.
Using anything else is just stupidity. You don’t even have to do anything special to the room/enclosure afterwards, because the only thing that was in the room was normal air. Just be sure to check the oxygen sensors before you walk in.
You just described the kill floor I used to maintain. Instead of nitrogen it was co2.
