Lady I work with said she was in the row immediately in front of where the guy fell into Section 110. They heard this big thud and turned around to a guy laying across some chairs and 2 screaming ladies who were injured. She said people started calling for medical/EMT and a bunch of people started running over. The cops moved in and told everyone to move out of that area of the section. The dude came to and was apparently flipping out and was arrested (or at least restrained at that point). They dealt with him and came back to administer assistance to the two ladies he fell on. I asked her about them, and she was like, "I don't know. The cops were screaming "go back to your seats" and she and her husband say, "Well you're in our seats" and they went, "Oh." So they went outside to smoke a cigarette and then just came back and didn't care. That's all I could get, but I'm glad that guy didn't fall on her and her husband at least.
All I could think is that someone is going to be traumatized, their concert experience will be ruined and they might not be able to listen to Tool ever again. But the guy didn't die, so none of that happened. I am just glad that everyone was able to walk away, relatively uninjured.
