Damn. If only the entire United States was just rural country. Then, people would just stop killing each other with guns. Ban urban inner cities.
Not sure if you're aware but, Chicago is also a part of the United States and a large amount of guns exist there as well.
I don't know where you live, but it's implied that you don't live in the inner city. This probably means that you know the people who are likely to be around you at 3am. Or, you don't have anybody around you at 3am. I live in a place like that too. This is important. If you could walk around any inner-city in this country where you are surrounded by strangers, some of whom, you know are packing and you just don't know who, and still feel as safe, over the long run, as you do in your hometown, you'd have an argument here. Oh yeah! you have a gun to defend yourself with right? Good luck with that bro. MAD only works as a reliable deterrent on the international scale. On the individual scale, one or both just get shot.
Seoul, Busan, Daegu, Incheon, and Daejeon are all huge urban cities with population density higher than a city like Chicago. I can tell you that people in those cities feel safe. Just as safe as you do in your place despite the crazy amount of strangers around them. You tell me what the difference is.
Why do cops need guns here? There are a lot of countries where the cops don't carry firearms. Tell me why they don't need them.
How many cop death incidents would we have on our hands if they also didn't have to carry firearms.
Just to be clear, my argument here isn't that we should immediately try to ban all guns. That's clearly unrealistic. I'm only saying that if it were possible, from a theoretic standpoint, to make all guns disappear in this country, it would be a good thing.
