In a recent development, the Supreme Court has decided not to intervene in the planned execution of Kenneth Smith, making it the first known use of nitrogen gas for a death sentence in the United States. Smith, who was convicted by the state of Alabama for a murder-for-hire case in 1988, had initially requested this untested method for his execution after experiencing difficulties during a lethal injection attempt in 2022. However, Smith has now expressed concerns about potential 'super added pain' and is seeking to reverse the decision.
There are several legal concerns surrounding this untested method, with experts questioning its compliance with the Eighth Amendment, which prohibits cruel and unusual punishment. The proposed approach involves nitrogen hypoxia, a process that deprives the body of necessary oxygen to sustain life. The execution technique would entail placing a plastic mask over Smith's face and introducing a large volume of nitrogen instead of oxygen. The intended outcome, if successful, would be rapid loss of consciousness followed by swift death. However, the lack of prior implementation raises doubts about its efficacy, further compounded by Alabama's secretive approach to the protocol.
