Anyone that isn't a resident in the US should have no opinion on the matter because it doesn't concern them. States with more guns and more lenient gun laws have lower gun-crime rates than states with strict laws. That's just a fact in the US. As for implementing a gun ban, that's completely impossible in the US. There are hundreds of millions of guns legally owned in the US. Those guns are used in a nearly non-existent amount of crimes. The guns used in the vast majority of crimes were bought off the black market or stolen by criminals, who already can't legally own a gun. If you want to get rid of gun crimes, get more funding for the ATF so they can apprehend and charge gun traffickers, and work on the mental healthcare in this country so people that are mentally disturbed can be located and treated properly. Suicides count in the gun-related death statistics. Gang violence counts in the gun-related death statistics. Responsible gun owners aren't part of those statistics.
