New England is the exception to the rule; as I said there's a visible trend of more gun states = more death states. It is not always true, but it is more often true than not.
Also, while my list doesn't specify where those crimes occur, my list as I have stated includes Arkansas, Wyoming, South & North Dakota that have no large cities but still have astonishingly high murders.
Thus, the argument of yours that murder in USA is just because of a few aberrant cities is clearly wrong; there are murders everywhere in USA, and they have greater concentrations (usually) in gun-happy places.
Here is a rural area in Greece, with population similar to Wyoming and without big cities. Crete... where guns are prevalent although they are technically illegal. Many people own guns and all.
The study is in Greek.
From 1987 to 2021, in 35 years, there have been 337 murders in Crete. That's easily
double the ratio of murders in other parts of Greece that don't have as many guns.
And BTW, the ratio of homicides in Crete, is about
half that of Wyoming.
And now, about Immigration. Greece does have a problem with illegal immigration. During the Arab Spring years, we had about a million of illegal immigrants and asylum seekers in a country the size of (and the population of) Ohio. That is, about 1/12 people currently staying within borders around 2015 were illegal immigrants. And not people overstaying their visas, but traumatized people coming from war-torn countries.
And yet, we never went more than
a quarter of the murders Ohio has.
You are trying to put the blame for the tens of thousands of murders of USA in a few democrat, anti-gun cities and immigration. That is not true and doesn't hold up to scrutiny.
