For the worst crimes, life without parole is better, for many reasons. I’m against the death penalty not because of sympathy for criminals but because it isn’t effective in reducing crime, prolongs the anguish of families of murder victims, costs a whole lot more than life in prison, and, worst of all, risks executions of innocent people.

The worst thing about it. Errors: The system can make tragic mistakes. In 2004, the state of Texas executed Cameron Todd Willingham for starting the fire that killed his children. The Texas Forensic Science Commission found that the arson testimony that led to his conviction was based on flawed science. As of today, 138 wrongly convicted people on death row have been exonerated. DNA is rarely available in homicides, often irrelevant (as in Willingham’s case) and can’t guarantee we won’t execute innocent people. Capital juries are dominated by people who favor the death penalty and are more likely to vote to convict.

Keeping killers off the streets for good: Life without parole, on the books in most states, also prevents reoffending. It means what it says, and spending the rest of your life locked up, knowing you’ll never be free, is no picnic. Two big advantages: -an innocent person serving life can be released from prison -life without parole costs less than the death penalty

Costs, a surprise to many people: Study after study has found that the death penalty is much more expensive than life in prison. Since the stakes are so high, the process is far more complex than for any other kind of criminal case. The largest costs come at the pre-trial and trial stages. These apply whether or not the defendant is convicted, let alone sentenced to death.

Crime reduction (deterrence): The death penalty doesn't keep us safer. Homicide rates for states that use the death penalty are
