Yeah....because they can go to a gun show in Arizona, Nevada or another state and pick them up without background checks...or....in NY, they can go to Ohio, or PA....in Chicago, they can go to any of the surrounding states.
What you don't get is that background checks aren't hurting you one bit, the bill proposed purposely put in an item that would make a National Registry illegal, and closed a huge method that people who legally aren't allowed 2nd Amendment rights use to get them despite their ineligibility.
Now... you wanna yell some more?
