"Wow, that some really crazy and stupid claims. I mean, a lot of cultures were actually centered around music and dancing. However the other part is disturbing. I assum you already tried to track down the original members. It is also possible, that someone with actual brainpower and experience took over the "organization". A group of fanatics can be a powerful tool, if one can control them. In time, that leader can twist their ways to match his own agenda. It is a matter of patience and manipulation skills.
You mean taking out the guy, who placed them? It was suspicious enough that he was wearing an arena employee uniform and dispite there was no power outage, he walked around with a flashlight. It was the fact, that he raised that flashlight to blind me, while he reached behind his back, that convinced me, that something was not OK. After I found the suitcase, there was no more doubt. My bet was on a sniper rifle, wich would have been only good against a single performer. Now that we know it was a bomb and that there are six more of them, it is almost certain, that whoever planned the thing, wanted to target more "artists"...and an arena full of people. It would have drawn a lot of attention to their cause. Do we know anything specific about the bombs? I'm also pretty concerned that the security stuffed so many people into one small building. One of these bombs could cause a lot of casualties."
