Bottom line is that, whatever your stance on guns, your current system isn't working. Well, except for arms companies. It's working very well for them.
I honestly don't know if violent crime rates are directly related to firearms or not. At any rate, there are statistics that show that the UK has significantly more violent crime than the USA. Some studies claim the UK, per capita, has up to 5 times as much violent crime. Other studies claim it is less, only about twice as much. Regardless, it is interesting. Of course, some people claim you can't compare the UK to the USA in terms of violent crime, which makes me wonder: if you can't compare violent crimes across countries than why are we comparing gun deaths across countries? Unfortunately it seems like just about all these studies get manipulated by some group with an agenda... SIGH. Anyway, point is some claim the "higher violent crime in the UK" is because in the US people are allowed to have firearms and defend themselves. Whether this is true is highly speculative, although you can't outright dismiss it.

Also, an interesting statistic is that the majority of homicides with firearms are gang related. Mass shootings are of course horrific, and I'm not saying there shouldn't be background and mental checks. However, it is a fact that despite the media coverage they get, they are very rare. Secondly, what exactly constitutes a "mass shooting"? Technically it refers to an incident with more than one victim. Thus, if three gang members shoot it out that is technically a "mass shooting". Probably not what most people think of when they hear the words "mass shooting". Anyway, this is interesting to discuss. I'm honestly not convinced that other countries handle guns AND violence better than the USA. However, I'm always interested in hearing opinions and discussing things.
