You have to institute federal minimum sentencing and charge up the ladder of the transfer of the weapon ownership using "all in" laws. It's a simple problem to correct, really. Keep your guns, but if you commit a homie you and the owner go in or you and the private party who sold to you without a bg check go in.. etc.
Yeah, more draconian laws will remedy the situation.
Because similar draconian laws vis a vis the black market drug industry has successfully put a halt to drug trafficking, right? With all these football numbers they've been passing out to dealers over the past 30 years or so they've made it so soooo difficult for people to obtain drugs and have successfully detered people from wanting to deal drugs, right?
The only beneficiary of something like that would be the prison industry.
As long as there is a demand for firearms (like drugs) people are going to get them regardless of what a law or statute has to say about it. Especially given the reality of the wide proliferation of guns in this country, most of which are unregistered & untraceable because there's no gun registration in most states in the union. The state would only be able to trace the gun back to the original dealer who the manufacturer sent it out to. No practical way to institute something like that.
