FWIW, the United Kingdom's homicide rates (1.17 per 100,000) are much lower than the U.S., with gun death rates that are some of the lowest in the world other than Japan (although Japan has high rates of non-gun suicides). Almost all of the excess homicides in the U.S. relative to the U.K. and Japan are committed with firearms.
Canada's homicide rates, by province, are mostly lower than comparable U.S. states, outside of its Arctic territories.
Latin America's homicide rates are very high for the most part (mostly due to organized crime cartels using U.S. sourced guns), even though U.S. Hispanics commit crimes (including homicide) at a rate lower than native born Americans. Mexico, however, has dramatically reduced homicide rates under its current President.
