A death penalty opponent says he welcomes a study of whether lethal injection is really as humane as it’s passed off to be. Jeff Stack with Missourians to Abolish the Death Penalty says he’s glad the U.S. Supreme Court intervened and stopped the execution of Michael Taylor at the Bonne Terre prison last week. Stack says he’s encouraged that the Court has indicated it will take seriously the recent appeals centering on lethal injection. The High Court blocked the Missouri case and two in Florida. All raised objections to lethal injection.
