I never knew there were so many violent flash mobs. It's kind of disturbing. It's not even like they are roughing people up, people are being killed. These
truly are the 'dark side' of flash mobs. These are happening all over the world. That list was truly disturbing to see some of the ones it mentions, like a man was hit by a train when he tried to escape when he was being beaten and mugged by a group.
