As someone living outside the United States, sometimes it is pretty hard to comprehend everything that happens there.
The guns are crazy. The mass shootings and the tacit acceptance of them never end. Donald Trump and the apparent trainwreck that is the Republican party. The NRA buying politicians. As far as I can tell, most people outside the United States don't really understand the insane gun-nut culture that exists there.
In the wake of most horrific news events, change takes place. We realize something in the system is broken and close the loopholes that make future events improbable or less likely. Yet with guns, we do nothing. No matter how high the body counts reach, we hear the same refrains: now’s not the time to talk about guns, if anything we need more guns in more places, and perhaps most famously the only thing stopping a bad guy with a gun is a good guy with a gun.
That there can be tens of thousands of deaths in the United States every year from guns is insane. Than nothing can be done about it because of the culture and the Second Amendment is criminal.
