About the best analogy I can make is a pit bull introduced to dog fighting. They say once they get the taste of blood they are never the same. The mob has now gotten a taste of blood and there is no turning back. They literally can't help themselves now. They are like dope fiends but instead of being addicted to dope they are addicted to violence and destruction. These states have allowed this violence to go largely-unchallenged and now that is what the mob craves. They don't care who they get their pound of flesh from, just that they get the pound of flesh.
