Idaho is set to become the only state that uses a firing squad as its main method of capital punishment. The move, taking effect Wednesday, marks a sharp break with the lethal injection procedures common elsewhere in the country.

Indiana lawmakers are weighing a controversial bill that would permit executions by firing squad if lethal injection drugs become unavailable or if requested by an inmate. The proposal ignites debates on ethical boundaries, costs, and secrecy, underscoring continuing disagreements on the most “humane” method of capital punishment.
