Could you imagine working hard all of your life, whether it be in owning your own business, or working for your local government, only to see your future destroyed because of the death of one guy? All you want is to be left alone and make ends meet. Perhaps you worked hard improving your house or business in the hopes to sell it one day, possibly to move to a better neighborhood, or another city or state to be with family or friends. Then all of sudden within a couple weeks, one guy dies, your business is ransacked, and you can't sell your house because nobody wants to move to a city without a police force. Years and years of hard work down the drain, with your assets becoming virtually worthless overnight. Just because of one guy and the insanity of the masses.
At that point, you don't give a fuck about one dead criminal, or a thousand.
