Ah! Thanks for clearing that up. I understand your point. I'm not certain I agree though. As I wrote to another user downthread:
Maybe ultimately convincing judges to ban nitrogen hypoxia is a good thing over the long run, even if it results in short term harm. But that is not a calculus I feel comfortable solving on behalf of others who will suffer while I remain insulated from the consequences of this decision.
Using the stark, open, and obvious violence of a firing squad might make execution less palatable to the masses, but honestly, when are "the masses" actually exposed to footage of a criminal execution in the United States? We don't normally film executions, and even when we do, we certainly do not broadcast them. Despite being one of the most carceral nations, typically unless a person has actually personally experienced prison, he or she largely has no idea what even goes on at that level, let alone death row.
