These kinds of comparisons are constantly touted, and essentially meaningless. Why? because the social demographics are completely different. Different countries, different societies.
Try comparing homicide rates between Canada or the USA with third world countries with extremely strict anti-gun laws, and I'm sure you'll find some shockingly very high non-firearm homicide rates.
PEOPLE kill people. Plain and simple.
people with guns can generally kill more people than those without.....that's simple too.
