"It was a total melee," said [Carl Middleman], who witnessed the incident from the 12th row of the amphitheater. "I don't know if [Axl Rose] was provoked or not, but he seemed to fly off the handle. I think he could have handled himself better."

Rose, who left the amphitheater with his band as the disturbance grew, called KSHE-FM about two hours after the incident to express his concerns about the riot.
