A great friend of mine blew me away the other day. He's a gun guy and has had no less than a dozen AKs at one time since I've known him, among other weapons including his fully auto Uzi (yes, legal). He comes up to me the other day and asks me, "I know you're against all of the new gun laws and stuff, and I pretty much am too, and don't freak on my ass when ask you this, but what's so bad about making background checks mandatory?"

I made a few points and he was marginally convinced at best. Frankly, I can see how under-informed folks can think this. I mean, it sounds so good and harmless to them. I was a bit surprised that my shooting bud brought this up, but that's really besides the point.

What are the best talking points to combat this question?
