A stalker was ordered to stay away from Holocaust scholar Elie Wiesel for the next three years when he appeared in a California courtroom for the first time Friday to face charges of assaulting the Nobel Peace laureate. Eric Hunt, 22, who was extradited from his home state of New Jersey on Thursday, did not speak or enter a plea when he was arraigned in the Feb. 1 attack at a San Francisco hotel where Wiesel addressed a peace forum. His defense lawyer, John Runfola, said he was weighing an insanity defense in the case. "Eric has an undiagnosed psychiatric disorder," Runfola said outside court. "He is not a Holocaust denier,"
