The real issue here is this stupid idea that if they can just pass enough laws, criminals won't be able to get guns. They miss the most obvious: criminals don't have respect for laws, ANY law! Criminals by definition do respect or obey the law. Thinkng that laws will prevent criminals from owning guns only serves to disarm law-abiding citizens. the old saying is true: When guns are outlawed, only outlaws will have guns. Maybe that's too simple for the Leftist, the-State-is-my-god, Communist weenies to understand.
Unfortunately, when you just go ahead and comply with stupid laws, you only perpetuate them.
