Did someone just compare the crime rates of DC, a major city, to hicksville Michigan? REALLY now?
The problem here is that people believe more guns = more safety. Compared to every other country, this is solidly proven incorrect. Where do you people believe criminals get guns from in the first place? I'll give you a hint: they're not making them in the basement. They're stealing yours. You buying more guns = criminals getting more guns. It's as simple as that.
So yes, there's a small correlation to areas with more firearms mildly reducing crime. But there's an overlying correlation between no guns and markedly reduced crime much more than getting more guns. Furthermore if you actually look at the stats, the percentage of gun owners who actually have their guns for use during a crime is minuscule.
This all comes down to the ridiculous American mindset of "screw community, I'm looking out for me". It doesn't matter that if everyone agrees to tossing guns then crime gets reduced, because dumb hicks only look out for themselves, at the expense of others, and their neighbors repay the favor.
