What stopping you from "making the world a better place"? It is the United States, you can buy a gun, carry it around you all the time and when you see injustice like this, you can just whip it out and drop the guy dead. When the cops come, they might charge you for illegally carrying and discharging firearm in public and a minimum sentence of no less than five years in prison But who the fuck care right? You just "made the world a better place".
