The Pima County Sheriff's Office said it arrested Eric Fuller, 63, who was wounded in the knee a week ago in the shooting rampage that killed six and wounded 13. He was being held Saturday for alleged threats of intimidation and disorderly conduct and will undergo a mental-health evaluation. [...]

Toward the end of the taping, [Christiane] Amanpour brought up the issues of gun safety and mental health. As one member of the audience stood up and expressed his support for gun ownership, Fuller, seated near the front in an area reserved for victims and special guests, appeared increasingly frustrated and agitated.

Fuller then swiveled in his chair, raised his camera and took a photo of the pro-gun speaker, muttering, "You're dead," according to Joel Tranter, who was sitting behind him.
