Alabama is set to execute Alan Eugene Miller, marking the second use of nitrogen gas in the United States as a method of capital punishment. Miller, who has been declared 'mentally ill', faces a method that witnesses have described as 'horrific'. This upcoming execution raises serious ethical concerns, especially following the first nitrogen gas execution where the inmate reportedly struggled for two minutes. Despite criticism and the refusal of gas-mask maker Dräger to participate in the death-penalty supply chain, Alabama proceeds with its controversial decision, drawing increasing scrutiny from advocacy groups and the public.
