Gun laws != lower violent crime. Though I can't show you the statistics, take a look a couple of years back when Australia outlawed guns. Violent crime (especially home invasion) went through the roof). So there.
I was reading a book/article/talking to someone a while back and we came up with a
great idea. Outlaw all guns. But, make everybody carry around some sort of large edged weapon. Lets face it, are you gonna mug someone with a broadsword?
