Before some slimy politician gives you what you stupidly ask for, think about this.
How many of those failed back ground checks were denied because of mistakes due to incorrect information?
How many were denied because of the ex-post facto laughtenburg amendment that people didn't know they were subject to.
Did you know that in Pennsylvania before 1977 if you were convicted of shop lifting, drunk driving or reckless driving like drag racing or peeling out, you are denied gun ownership? All three of these small crimes, usually committed by teenagers, carried sentences of up to three years. There are probably a lot of other states that had the same laws and penalties.
So now you want to bring federal prosecution down on everyone that tries to purchase a firearm, even though they might not even know that they are prohibited?
Do some research before you spout off.
