Well, you just pulled that 99% out of your ass. And like I said before there is no concrete proof that it is a deterrent. I'm not going to argue this one with you because it is been proven multiple times by numerous sources that it is more expensive to sentence a man to death than to life in prison. They are both costly but capital punishment is much more expensive. People being sentenced to death are usually serial killers. Their sentences are extreme and most never even have the chance to get out. Plus there is a simple solution to that problem; life in prison without the possibility of parole. Shocking, yes I know. Did you even read my quotes? "if our legal system followed the cost-benefit analysis of economics, we would shoot all young, first-time offenders -- because we know they are very likely to offend again” The fact is that our justice system has moved toward a humane type of system. Using your logic, we should kill all first time offenders because statistics show they will commit crime again. Right? Probabilities and assumptions CANNOT be used to justify things in our justice system. Agreed.
