After taking into account the poverty rates, standard of living and education levels of the nations, what did your rates look like?
I am betting that area with equal poverty rates, standards of living and education levels showed a lower crime rate in the areas that were armed than the areas where the legal citizen was more often unarmed. Comparing a place in a great spot economically with a place in the shitter like the US is now isn't a fair comparison though, for us, getting rid of guns would actually make the crime rates worse.
