It's private industry. If you don't like dying in a fire, don't go to clubs that burn down. The invisible hand of the market at work. . .

Think of the wildest, most irresponsible adult you know. Now think of them hammered in a bar. Now picture them hammered in a bar openly carrying a loaded gun among a bunch of other drunk people with loaded guns. If this sounds like a good idea to you, you could be governor of Georgia or South Carolina.
