(Portland, OR)  --  Students at Portland State University are remembering a Navy veteran who was shot and killed by campus police.  Dozens of students ended their first day of the new semester yesterday with a candlelight vigil for Jason Washington outside the campus public safety office.  Earlier in the day, students held a march and rally calling on the school to disarm campus police officers.  Campus police shot and killed Washington in June while he was trying to break up a fight.  Police opened fire on him after he bent over to pick up a gun that had fallen out of his holster.  Washington reportedly had a concealed carry permit for the gun.
