Lies, damn lies, and statistics. Whilst I'm not disputing the actual statistics, things do get interesting when you broaden it out a bit. For example if you were to look at overall violent crime per 100,00 then the USA is at about 401'ish. Yet the UK is at nearly 1,800 per 100,000 people. But fair enough I would be disingenuous if I didn't highlight that the way the fbi record that figure is differently than the UK. So if we filter out violent crimes where there was not actual injury recorded, merely

a threat with the weapon then the UK drops down to about 700. Still 300'ish more than the USA dispute our gun control and many other laws.
Focussing on the weapon is the wrong focus imo. We should focus on the individuals involved.
