Totally off topic, but I loathe shitty bar graphs like this.
So we have a gun murder rate of .0037% as opposed to, say, .0006%. At the same time, we're referring to gun murder rate, not murder rate.
Honest question: if we were to ban guns tomorrow and wipe out all guns, legal and illegal, how much would the actual murder rate decline? It doesn't go to 0, and America's diverse racial, economic, and social groups create challenges unique to this country no other in the world had to deal with. No matter what the gun laws, we will have a relatively high violent crime rate in the world for dozens of other much more difficult to talk about reasons.
Gun violence is usually a symptom of many other problems. Eliminating the gun doesn't necessarily eliminate the violence. This asshole for instance seemed pretty intent to take those lives by whatever means necessary. So many of our heavily debated political topics are just easy ways to cope with deeper issues.
