Lawyers for four death row inmates who have run out of appeals are expected to argue to the South Carolina Supreme Court that the state's old electric chair and new firing squad are cruel and unusual punishments. Attorneys for the inmates also plan to argue Tuesday that a 2023 law meant to allow lethal injections to restart keeps secret too many details about the new drug and protocol used to kill prisoners. In the balance are the death sentences of 33 inmates who are on South Carolina's death row.
