Revise death penalty laws

This bill revises Montana's death penalty laws to establish specific procedures for carrying out executions. It mandates that executions be performed using a lethal injection of an ultra-fast-acting barbiturate combined with a chemical paralytic agent, administered by a person selected by the prison warden who does not need to be a medical professional. The law sets strict timelines for scheduling executions, limits the number of witnesses to 12 including representatives from the media, victim's family, and the condemned person, and requires the warden to maintain confidentiality regarding the identity and training of the executioner. These changes apply to all death sentences in Montana and govern how executions are conducted, supervised, and documented.
