A federal judge has ordered the Marines to discharge a San Jose lance corporal as a "conscientious objector" who had an aversion to killing and participating in war. Robert Zabala, 23, must be released from the Marines Corps Reserves by mid-April, U.S. District Judge James Ware said in a 21-page ruling Thursday. "We're very pleased with it," Zabala's attorney, Stephen Collier, said Monday. "I think it's a good decision and that it makes clear to the armed services that they can't deny conscientious-objector discharges from the military."
