When guns are outlawed, only lawmen and outlaws will have guns. Good. That's the state of affairs in every developed country except one and it's demonstrably better in every way.
You may not have realized that your statement is ambiguous between the state of affairs and the sole exception.
Either way you meant it, that is your individual belief based upon your own preferences, and there are literally millions of people who would disagree with you on this particular point. If there were no exceptions, where would all those dissenters go?
PS: I have actually been paid to look into crime statistics. Guns are bad, really really bad. But, you can twist statistics to say the sky is orange if you want to.
