I think that is B.S.
There is nothing BS about it, many studies in USA have shwon that death penalty costs more than life without parole.
First of all it's not necessary to keep a prisoner in prison for very long before "deep sixing" them. It's only the lawyers that keep the operation in limbo for so long. Realistically speaking the guy could be sentenced to death two years to the day from being found guilty & then he and his lawyers know that that is what is going to transpire. (And don't tell me "it doesn't work that way", because where there is a will there is a way)
Quite so JLM, where there is a will, there is a way, for death penalty opponents, that is. There are many organizations dedicated to getting rid of death penalty (such as ACLU), they fight each and every death penalty case to the bitter end.
They have many smart lawyers. They find every loophole, launch appeal after appeal, claim that new evidence has been found etc. and delay the process by ten years or more. In the meantime, in addition to the cost of housing the prisoner, there is the cost of district attorneys, defense lawyers, judges, maintaining the court rooms, salary of ancillary staff etc. The expenses mount and it becomes more expensive that life without parole.
For life without parole, there is one appeal and that is it. ACLU or others don’t fight each life without parole case to the bitter end. When the appeal is granted (and criminal found guilty), that is the end of the process. Then there is only the cost of housing the prisoner for life.
That is why death penalty is much more expensive than life without parole. As to executing a criminal two years after being found guilty, the law needs to be changed for that. It should be evident to everybody how difficult it is to change the law in USA in the face of a determined majority or even a minority (as is becoming evident from the health care fiasco). I don’t see it ever happening. Under the current system, death penalty indeed is more expensive than life without parole.
