Riverport Riot was an infamous Riot that took place in 1991 in St. Louis.
Guns N' Roses were performing their song Rocket Queen and Axl Rose saw some guy with a camera and because he hated cameras, he tells the security to take it away from him by saying "Hey, take that, take that, now. Get that guy and take that?" But the security refused to, Axl handled the situation himself by saying "I'll take it god dammit!" and jumps into the crowd to beat the guy up.
After beating him up, Axl went on the stage and said "Well, thanks to the lame-ass security, I'm going home!" and he smashed the microphone, which caused a riot.
2 people were killed, Axl Rose got arrested and hundreds of dollars was costed. The riot was also known as Rocket Queen Riot.
