Why do people riot during peaceful protests or happy gatherings?
I've noticed that a lot of times, when there's a large group of people, riots usually ensue. Even if it's born from protests AGAINST violence or from happy times like your home team winning the world series/cup/superbowl. These are especially common in football(eu[no offense, but it's true]) and I seriously question why people have the urge to hurt others, destroy property, and loot stores for something that's GOOD.
