The other countries cannot be compared to the US regarding gun ownership and use, period.
Find another country the size, and the multinational demographics of the United States, that comes even close, that also has FIFTY independent state governments.
The US is the THIRD largest country by population and the fourth largest by area. Of the four, only two are non-communist countries or communist dictator led countries. The diversity of cultures is unmatched as is the geography/boundaries; political-constitutional makeup.
I guess you overlooked your "next door neighburs" here in Canada? While our population is "just 40 million people " compared to that of the USA, we do have very strict fire arms laws, and in particular the ownership and use of hand guns. No body in Canada can carry a hand gun in public, except on duty Police officers, on duty members of the Canadian Forces Military Police, and on duty armed security guards on an armored cash in transit truck.
If a person applies for a hand gun permit in Canada, the approval process takes up to a year to be completed. If the person has previous convictions for violent crimes, especially for domestic assault, the application will be automatically denied. Part of the background check involves in person interviews with the applicant's family, and if any adult relative objects to the issuance of a hand gun permit, it will be denied.
Legally owned hand guns in Canada, MUST be locked in a gun safe, unloaded, with a trigger lock on it, at all times, with the ammunition in a second locked safe. The ONLY place where a legal hand gun can be shot in Canada is at a registered gun range. The hand gun MUST be transported directly TO the range in a lock box, and directly BACK home again, afterwards.
In the year 2022, there were a total of 874 murders in Canada, of which 342 were by firearms. By comparison, in Chicago in the same year, there were 2,656 shootings, with 605 murders using firearms. Toronto and Chicago have just about equal populations, but the number of murders by firearms are very unequal. In Toronto in 2022, there were 78, while in Chicago there were 605 murders using guns. In the majority of the gun murders in Canada, the fire arm was smuggled into Canada from the USA.
So the country that is right next door to the USA geographically, has way fewer deaths by guns than the USA does, even when you take into account the population difference between the 2 countries. In my opinion, this speaks to the history of the 2 countries in terms of how they emerged and developed over three centuries. JIM.
