This is the strongest argument against the death penalty, or one of them, as if it is correct they can convince an unelected supreme court to subdue the death penalty. Anti-Death penalty groups such as the Death Penalty Information Center (DPIC) try to capitalize on these arguments all the time. I think this is the vilest strategy of the abolitionist crowd. However, their claims are all false, and as usual the abolitionist crowd is good at ignoring facts.
The claim the death penalty (may be referred to, as the title already does, “DP”) costs to much is one of the most common claims about the death penalty. The history of it really began in 1970 when abolitionists began to back down from morality claims as they had little ground to stand on. So they decided to take a whack at the administrative “problems” of the DP, such as race, innocents, and costs. We will only look into costs in this article to make it simpler.
