“Gov. Gavin Newsom of California moved to spare the lives of all 548 prisoners on the state’s death row on Thursday in the largest mass commutation of death sentences in modern American history,” the New York Times reports.“Mr. Newsom said he made the decision because he finds capital punishment morally objectionable. He reduced every death sentence to life in prison without parole, a sweeping move that will require a review by the state’s highest court in some cases and could draw legal challenges.”
