Alabama just executed its second murderer by nitrogen. It was reportedly not pleasant:

Alan Eugene Miller, 59, was pronounced dead at a south Alabama prison. He shook and trembled on the gurney for about two minutes with his body at times pulling against the restraints. That was followed by about six minutes of gasping breathing.

And yet, we are told that suicide by nitrogen in the suicide pod is peaceful and dignified. So, which is it?

This is another example of what I call cruel and unusual death with dignity.
