I think you meant to say UNdeveloped countries. Places where everyone is banned from owning a gun, the criminals run rampant. Look at Mexico. Guns are banned there. Yet mexico has more murders in a week than the US has in an entire year. In contrast, look at Switzerland. The Swiss have the highest gun ownership percentage in the world. And one of the lowest murder rates in the world too. Last year, more people in Switzerland were stabbed to death, than were shot. In summary, guns prevent violent crime, because the criminals are going to own them no matter what the law says.
