The 4473 form itself is indeed a joke in it's current state. It is executed by the purchaser, at the gun counter, with zero information that can be trusted. The current "background check" is time consuming, is many times falsely rejected or delayed, and as was pointed out, no criminal with a minimal amount of grey matter between his ears would be stupid enough to submit to one.
Look at firearm purchases before the 4473 form existed, (pre 1968). There were no school shootings. Far less gang violence to citizens, and zero guns found in schools themselves. A kid growing up in the 60's wouldn't even entertain the thought of bringing a gun into school. Now it happens on a daily basis, forms, background checks, and all.
What is wrong is society itself, and no amount of laws, background checks, or badmouthing of firearms will change it. We need something to blame. First in the 70's it was the "Saturday Night Special", what ever the hell that was. Now it's "Assault Weapons". In another decade they'll find some other buzz word to blame it on. Lousy parenting along with a deteriorating educational system and family values that are all but non existent, is what is bringing all of this about. Anyone with working sexual organs can reproduce children. We have seen it takes far more to be a parent, and checking a few boxes on a yellow piece of paper won't make up for that responsibility.
