Ayaaa, we had a conversation a while ago about this same topic. I do think you are still correct in your proposal to make NICS public, but I do also think that the other guy is perhaps partially right. I think such a law would probably be well-accompanied by requirements to own a gun safe (which might be seen as increasing the cost of ownership and thus discriminating and yadda yadda yadda shit I don't care about), and to keep guns in said gun safe when perhaps they're not being kept immediately on your person barring extraneous circumstances. I can't quite recall, but I do believe we also talked about that last time, that there was a kind of need for common sense pertaining to the handling of guns, more than there is, considering how many guns are overwhelmingly passed into illegal uses through relatively simple theft.

I'm also not sure I agree that a violation of the background check, being a fine, is going to have much of an effect. If the fine is cheap enough, that might well enough be just free license to pass guns into an illegal domain and then pay the fine and go about your day. It may increase the costs of illegal firearms well enough which might have knock-on effects in decreasing illegal access to and usage of guns, and what have you, but I think it would probably require a more severe punishment than a fine a la a traffic ticket.

But then, maybe if that's the metaphor we're using, then along the lines of traffic tickets, maybe we should just be, uhh, designing the roads differently, whatever that equivalent might look like for guns, but I think that might be stretching the metaphor a little too much.
