The U.S. Supreme Court has yet to intervene on executions based on 11th-hour appeals challenging lethal injections despite controversy surrounding lethal injections, according to NBC News. But a recent vote in the court may indicate that the justices might dispute the issue in the future. Because the supply of traditional deadly cocktails used to carry out executions is shrinking, states have found other sources for drugs without naming their specific pharmacies. Defense lawyers have criticized states for keeping a veil of secrecy.
