Back in the United States, Oklahoma’s attorney general said Wednesday the state will seek to put prisoners to death using asphyxiation by nitrogen gas. The proposal comes as Oklahoma has struggled to procure lethal injection drugs following a string of botched executions. In a statement, Dale Baich, an attorney for Oklahoma’s death row prisoners, said, “This method has never been used before and is experimental. … How can we trust Oklahoma to get this right when the state’s recent history reveals a culture of carelessness and mistakes in executions?”
