The exoneration of two North Carolina men who spent 30 years in prison — one on death row — provides a textbook example of so much that is broken in the American justice system. And it is further evidence (as though more were needed) that the death penalty is irretrievably flawed as well as immoral.

In late September 1983, an 11-year-old girl named Sabrina Buie was found murdered in a soybean field in Robeson County. She had been raped, beaten with sticks and suffocated with her own underwear.

Within days, police got confessions from two local teenagers, Henry Lee McCollum, 19 at the time, and his half brother, Leon Brown, who was 15. Both were convicted and sentenced to death.

The crime was so horrific that it has echoed for decades through North Carolina politics and beyond. In 1994, after Justice Harry Blackmun of the Supreme Court announced that he opposed capital punishment in all circumstances, Justice Antonin Scalia cited the Buie murder as a case where it was clearly warranted. “How enviable a quiet death by lethal injection compared with that!” he wrote.
