I'm curious why the singer was labeled controversial. I guess only the statement that was made about security. I remember the event in this article happening because I like the band, and was familiar with them, and it could have been me at the show. All of those people were innocent and had no idea what was going on, didn't ask for it, etc. Hearing the stories was really traumatizing. I can't even imagine. I'm glad that everyone is able to overcome.
