I think I expressed myself poorly. They aren't using banned things because they are banned. Instead, they go the easier route of killing people with non-banned things.
shows a wide variation among US states. Curiously, some of the states with the lowest stats have essentially no gun control. So its more complicated that it might seem.
So seems like it's easy in Brazil to illegally own a firearm. I suspect the UK avoided a similar outcome by not only making it illegal, but also policing in such a way as to make it difficult to illegally own a firearm.
I read a statistic stating that somewhere around 80% of the violent crime in America takes place in about 5% of the counties.
In other words, there are certain niche demographics in America that are pulling up those gun murder stats, and it's generally not a problem for most people who enjoy 2nd Amendment protections.
You are being very very selective with the data. Assuming good faith please refer to the rather larger dataset with gun ownership and gun crime data for many countries provided in another post.
Knives were banned because of an surge in knife crime. Guns have obviously been banned for an age. I suspect you have an ulterior motive.
