An anatomy teacher had called campus security after Zaccagni displayed erratic behavior in the classroom. The teacher was alarmed when Zaccagni was using a scalpel to make gestures to his throat. Campus security discovered a loaded handgun in Zaccagni's coat pocket. And even though Zaccagni claimed he has been around firearms for most of his life he admitted he did not have a permit to carry the weapon.
"The permit application is sitting on my China cabinet at home," Zaccagni said. He told reporters he "forgot" he had the loaded gun in his pocket. "I'm very sorry. I'm going to get expelled," he said.
