“A murder should only have one victim. When Ratchett kills Daisy Armstrong, a dozen lives are broken, deformed, ended, THEY DEMAND JUSTICE! Of all these wounded souls, we must finally answer — who among them is a killer? Who takes up the knife? The answer is… no single one of you could have done it. Nor any pair. It could have only be done… by all of you."*

But that’s fundamentally a flawed argument. It’s more expensive becuase death penalty cases have more rights. Specifically in the US what is called “actual innocence” is not grounds for an appeal to a life sentence but is for a death penalty.
Ideally we would extend that everyone, not save a few bucks and justify continued incarceration of innocent people by noting “hey it’s not a death sentence.”
Imagine the scenario of an innocent person who can’t appeal becuase the trail was fair but would have been freed if they had been sentenced to death, but becuase of the judge or jury’s mercy, they are imprisoned for life.
That has happened here.
Not think a great argument for abolishing the death penalty since it fundamentally is just saying “it is way too expensive to let any prisoners appeal based on being innocent. We could save so much money if didn’t let anyone do that.”
