Statistics are such a wonderful things, it makes ones point regardless of how accurate that point might be. Curious you used AJM research rather than FBI research, but no matter. 

By leaving out critical data like  where/who/what/when you misrepresent what is actually happening. Most of the murders you report take place in the inner city and are drug gang related. ESPECIALLY in the 15-24 age range.

As for europe's statistics you are not comparing apples to apples. They don't track things the way we do. One example is, if the crime is unsolved it does not make the statisic. And that is just one example, they have several differences that would leave something off that we add.

For the most part, Europe has per capita more violent crime, that the USA by a fair amount. Agreed, it is not gun violence, but my daughters carry guns to stop rape/assault. Note, if she has to use it, it will be classified as gun violence!
