Yeah, I get it.
So, can't you get people to end the debate on banning firearm ownership or purchase for convicted felons?
Actually most states ban ownership of firearms by felons. But they don’t mandate that all of the people who provide firearms to others to verify they aren’t felons.
Best analogy would be: our current alcohol laws except if a 17 year old standing outside gave 22 year some cash to a 22 year old alcoholic who went in and bought two bottles booze - 17 took one and the 22 year old keep one and in such a case the 17 year old broke the law but the 22 year old was under no obligation to make sure the 17 year old was old enough. So all night long the bum hangs out in front of the booze store. And there is nothing the police can do because they can't ask the minors for id unless they already know they are under 21.
That is the gun show loophole. Criminal love it because they can get guns without background checks. Sellers love it cause they can charge a hefty premium.
If the goal is to make alcohol more expensive for minors but absolutely do nothing to actually stop underage drinking it is a great loophole. Same thing here.
