Alabama moves closer to allowing death row inmates to be executed with nitrogen gas. This method is only available in two other states and has never been used. The House Judiciary Committee approved the measure today without debate. Senator Trip Pittman says the bill offers a painless way to put a person to death and is more humane than lethal injection or the electric chair. The Montrose Republican says Alabama needs another execution method as lethal injection faces legal challenges. The bill will now move to the full House.
