I wonder how that is factored in? Wouldn't it make more sense to use gun crimes committed with small arms as the factor?
Arizonans have free access to all kinds of weapons and we didn't make either list, we ranked 37. While our freaky gun control neighbor California ranked 33rd.
Just being in the USA means it’s easy to get a gun (Mexico would be in that category too). It’s kind of like how door locks are mostly there to stop trivial mischief makers, not serious criminals.
