New California Lethal Injection Procedure:  LA Times writer Carol J. Williams reports on California's proposed new lethal injection procedure.  This would allow California to resume executions after a four-year moratorium.  The proposals involve only minor changes to the three-drug method, but the revisions appear to address the concerns of a federal judge who deemed the previous lethal injection practices unconstitutional for their risk of inflicting cruel and unusual punishment.  Experts predict that the legal reviews will take months, but that executions could resume as soon as this year if the changes put to rest the judges' concerns.
