Idaho has become the latest state to turn to older methods of capital punishment due to a nationwide shortage of lethal-injection drugs, with Republican Governor Brad Little signing a bill allowing execution by firing squad. Pharmaceutical companies have largely barred executioners from using their drugs, prompting other states in recent years to revive older methods of execution. One Idaho death row inmate has already had his execution postponed multiple times due to the drug scarcity, and the new law is expected to take effect on July 1, 2020.
