(CNN) -- New Mexico Gov. Bill Richardson signed a bill Wednesday repealing the death penalty in his state, his office confirmed.
"Regardless of my personal opinion about the death penalty, I do not have confidence in the criminal justice system as it currently operates to be the final arbiter when it comes to who lives and who dies for their crime," Richardson said in a statement Wednesday.
He noted that more than 130 death row inmates have been exonerated in the past 10 years, including four in New Mexico.
"Faced with the reality that our system for imposing the death penalty can never be perfect, my conscience compels me to replace the death penalty with a solution that keeps society safe," he said.
Good job, Billy.
