Norway has open borders, and the murder rate was
0.5 per 100 000 inhabitants in 2021. Meanwhile, the murder rate in the US was 6.8.
Fine, we're pretty small and isolated from the rest of the world. What about Germany? It has a population of 80 million and is pretty centralized (refugee crisis and all) — murder rate: 0.9.
Well, at least there's no cartel wreaking havoc at the German border. What about Turkey? It borders Syria, which has been in civil war for 13 years, and Iraq, which... well, you know. And let's not forget that whole ISIS ordeal. Murder rate: 2.5.
What about Alaska? It borders a bunch of Canadian trees.
Murder rate: 10.2.
No, wait! It must be because the United States have Democrats! Nope.
Turkey's got Democrats too.
Sorry to pop your bubble.
