I don't live in a country where individual arming this much causes shooting anywhere in daily life.
I don't live in one either either. I think people really need to educate themselves about America's violence problem. It's also a fallacy to compare US with other countries pertaining to gun legislation when there is no comparison. It is a common argument to say that gun laws work in other countries; meanwhile, within the US gun laws are not working. Over Memorial Day weekend, there were over 40 shootings in a city where it's harder to buy guns than it is to buy drugs.
The USA has more guns than it does citizens. There are no comparable countries.
