If I have a choice of putting someone to death for $5 million, or incarcerating them until the end of their natural life for $1.5m, I will always choose the latter. The US has debt of $36 TRILLION for fuck sakes. When you owe $36 trillion, you don't have money to spare on the spectacle of more expensive executions. If we can't immediately figure out a way to fairly put people to death at a cost that is equal to or less than keeping them in prison until they die, we should abolish the DP for that reason alone. There is no utility in it. Plus, we make martyrs and celebrities out of these folks on death row. They are getting interviewed on Netflix documentary shows for fuck sakes. They should be in there with the LWOP folk doing real, hard, bleak time.
You are trying to impose some humanity argument on me that I never made. My argument has always been completely about the cost. I'm not particularly concerned with the accommodation of our LWOP inmates. I would prefer they not be abused, tortured, or starved. But other than that, I'm not really bothered.
