People line up for entry into the U.S. Supreme Court where justices are debating whether executions of teenage killers are unconstitutionally cruel, in this October 13, 2004 file photo. It's not official, but a "creeping moratorium" on the death penalty in the United States is taking hold as the Supreme Court prepares to hear a challenge to the method of lethal injection.

He had already eaten his "last meal." To match feature USA-EXECUTIONS/ REUTERS/Kevin Lamarque/Files (UNITED STATES)
