Fight at Mindless Behavior concert

According to sources there was a fight at the Mindless Behavior concert. In the video clip it shows two boys very likely in there teens getting into a dispute and fist's being thrown. This blogger speaking on it at the end didn't seem too thrilled about it but he makes some great points. Why can't people nowdays just go to a concert without getting into a fight or causing trouble? Well i don't know the answer to that one maybe you do but checkout this latest video and feel free to let me know what you think about it.
