There are criminals in California who have never murdered anyone, yet are sentenced to life in prison because of the 3 strikes law. Do you think we should kill these people as well so we taxpayers can save some money?
And if we save some money, we really don't save
all that much money. Sure, the drugs themselves that are used in lethal injection cost less than $100, but it's the process in getting the prisoner to the gurney itself that is so expensive.
It isn't the amenities that are so costly - it's the maximum security we put for death row inmates, the legal costs of even a single appeal (and death penalty cases are far more expensive than regular court cases for first degree murder), and court costs to prosecute in the first place.
This is where I part with proponents for capital punishment when it comes to the money issue - if we are to live with a system that can hand down a punishment as final and irreversable as death, then we better make darn sure more than anything else that this sentence is the most fair consequence and punishment for the crime. And truthfully,
this takes time and money. I disagree wholeheartedly with the notion that we could live with compromising fairness in our justice system by speeding up executions in order for us to save some tax dollars.
