Well, I guess it's hard to stop this kind of people. They don't understand they might even cause a non-camera statement in the future (no pictures as well). The only thing we can do is thank these idiots for ruining everyone's gig!
This kind of people will not understand and think they can operate above the law. So, it doesn't make sense, don't get angry anyhow, they'll be kicked out sooner or later.
