Alabama, having exhausted its other alternatives, executed Kenneth Eugene Smith tonight by fitting him with a mask and then pumping it full of nitrogen:
Witnesses saw Smith struggle as the gas began flowing into the mask that covered his entire face. He began writhing and thrashing for approximately two to four minutes, followed by around five minutes of heavy breathing.
This has prompted a lot of hand-wringing, but the convulsions are autonomic reactions. Smith was almost certainly unconscious when they happened.
The death penalty doesn't happen to be big hot button of mine, but I understand the opposition and I'm certainly OK with ending it. Still, if it's going to be done, I have a hard time understanding the endless controversies over the precise method it's applied. Nitrogen is fine, and almost certainly painless. Ditto for helium, once a favored method of suicide. That's because human choking reflexes don't respond to what kind of gas you inhale, only to a buildup of carbon dioxide. Obviously you don't get that when you breathe pure helium or nitrogen, so you barely even know anything is wrong. This is why accidental asphyxiation via nitrogen is fairly common.
Hanging is also painless. So is the guillotine. So is a firing squad if it's not botched. By contrast, lethal injection is idiotically complicated and never should have been adopted.
Opposing the death penalty is fine. But trying to pretend that even a brief and theoretical moment of discomfort is the real problem? That makes no sense.
