Oklahoma prison officials have released a new protocol for executions following April’s botched lethal injection of Clayton Lockett, which lasted 43 minutes. Media witnesses described Lockett writhing and moaning in apparent agony. Lockett was injected with an untested cocktail of drugs, which included midazolam, a sedative also used in other prolonged executions, including one that lasted two hours in Arizona. The new protocol in Oklahoma allows the continued use of midazolam, but calls for a dose five times what Lockett received. Changes also include more staff training, contingency plans for when problems arise, and a reduction of the number of media witnesses at executions by more than half — from 12 to five.
