"In this Feb. 5, 2015, file photo, Utah Gov. Gary Herbert speaks to members of the media during a news conference at the Utah State Capitol, in Salt Lake City. Utah became the only state to allow firing squads for executions Monday when Herbert signed a law approving the controversial method's use when no lethal-injection drugs are available. Herbert has said he finds the firing squad ""a little bit gruesome,"" but Utah is a capital punishment state and needs a backup execution method in case a shortage of the drugs persists.
