On July 2, 1991, at the Riverport Amphitheater in Maryland Heights, Missouri, just outside of St. Louis, during a performance of "Rocket Queen", Rose noticed that a fan was filming the show with a camera. He asked the venue's security to take away the camera, and after a few seconds decided to take it himself, jumping into the audience and tackling the fan. He had a heated confrontation with the fan before physically assaulting him. After being pulled out of the audience by members of the crew, Rose said, "Well, thanks to the lame-ass security, I'm going home!", threw his microphone to the ground and stormed off stage. The angry crowd began to riot and dozens of people were injured.
