Wow, I didn't know this happened and I sorta followed I+e tour.
I think people weren't really trying to touch Edge, Adam or Larry (they looked like casual fans who only cared about singing Bono). Good reminder not to try to touch or hug them. I'll just wave excitedly and grin at them if I ever get to see them up close.
I'm sure band+crew were royally pi**ed. Though crew can't show it or do anything about it.
