YOu might need to look at it in a different way. Go beyond the headline numbers and look at the detail.
I saw a study about 10 years ago (I cant find it now) that analyzed homicides by ethnicity. It found that for every ethnic group among immigrants that move to the United States, the homocide rate of that group in the United States was LOWER than that same group in their native land.
In other words, Canadian immigrants living in the United States, actually have a lower homicide rate than the homicide rate in Canada.
Japanese Americans commit less murders, have a lower homicide rate, than the Japanese in Japan.
Kenyan, South African, Ethiopian, Sudanese, Nigerian, and Tanzanian immigrants living in America commit fewer murders than Kenyans, South Africans, Ethiopians, Sudanese, Nigerians, and Tanzanians still living in Africa.
Pakistani’s living in America commit fewer murders than Pakistani’s living in Pakistan.
Danish people who immigrate to America commit fewer murders than the Danes in Denmark.
…and so on and so forth. If you search you can probably find that or a similar study by ethnicity. I have seen at least a couple of similar studies dealing with Canadians and Japanese, both of them have lower homicide rates if they live in America. I also know/saw a separate study that the FBI has done comparing/confirming statistics of the Japanese living in America , and they found Japanese Americans living in America to have a very small homicide rate, even smaller than Japan’s rate of Japanese living in Japan.
It was kind of interesting that when Canadians move to Florida(where they can buy and carry guns) they commit much fewer murders than the Canadians they left behind in Canada who have less access to guns.
Of course, bottom line: I really dont care what other countries do, its none of my business, and they can do whatever they want. I have had friends and relatives tell me enough over the past 70 years about how dangerous Western Europe, Mexico, Eastern Europe/Soviet Union, etc have been at various times, that I will feel safer carrying a gun in America any day than the stories I heard.
(Note that different countries count “homicides”, or what is homicide, differently, so international comparisons have to be studied closer than just looking at the numbers on the bottom )
