You wouldn’t want to impose any serious closing hours on your bars in a city where every drunk fucker has five guns; better to wait until two AM when everyone’s maximally drunk and concentrated in a chaotic nightclub with other violent people in order to insure a mass shooting.
This keeps happening in our gunniest, stupidest, bloodiest, cities – the late-night lounge loaded with bullets; the hours of bar-boosted boozing; bad behavior that finally gets you thrown out and makes you vengeful blahblahblah. Absolutely by the book. Absolutely happens every weekend somewhere in the states.
Cities with a flicker of brain activity have begun imposing relatively early closing hours on their abattoirs, but apparently Amarillo prides itself on its status as one of America’s most dangerous cities.
