@George-K said in A Simple Solution:
Any meaningful comparison has to compare the populations.
Would it be possible that the population in Denmark is just a wee bit more homogeneous than that in, say, Chicago?
I've been told that London is a warzone filled with police no-go areas, and Birmingham is 100% Muslim 😀
I know, you're right. It's apples and oranges. However, it's possible it's not just the populations that are different, but the attitude of the powers that be of how best to deal with the problem.
I don't think it's homogeneousness (is that a word?) so much as the culture - London is cosmopolitan, but doesn't have the same issues and gang crime, at least to anywhere near the same level.
