A U.S. District Judge in Alabama has denied a preliminary injunction request to block the upcoming execution of Carey Dale Grayson by nitrogen gas on November 21. The judge ruled that Grayson did not meet the legal burden required to prove that the method is unconstitutionally cruel.
The nitrogen gas execution protocol involves placing a respirator gas mask over the inmate's face to induce death by lack of oxygen. Critics have raised concerns about the effectiveness and potential pain caused by this method.
