Ignoring the moralities and can-of-worms question of the death penalty itself for a moment, I've always thought the reasoning of "life without parole is cheaper, so let's do that" was flawed. Why not figure out why the death penalty process is so expensive, and fix that instead? Then you can have your moral & ethical arguments without adding economics to an already hairy debate. I would bet the costs are rooted in over-inflated legal fees and prosecutorial inefficiencies which should be fixed in any case.
