Supreme Court intervenes in Oklahoma execution case.

The US Supreme Court has granted a rare stay of execution for Richard Glossip, an Oklahoma death row inmate who has maintained his innocence in a 1997 murder-for-hire case. The state's attorney general has said Glossip may be innocent and should not be executed. Glossip's clemency plea was denied by the Oklahoma Pardon and Parole Board last month, prompting his attorneys to ask the Supreme Court for an emergency stay of his sentence. The court's intervention was necessary as the attorney general had already confessed error, and an execution under such circumstances would be "unthinkable," he said.
