First, and let's be clear about this, our President didn't lie. He told you all along he was in favor of commonsense control on guns. That would be HIS sense of what's common, not ours, but the way.
Secondly, imy "common sense" gun law would be this.
"The inalienable right of all people to keep and bear arms, shall not be infringed by federal, state or local government!"
No if's, and's, or but's.
Of course, that would necessitate overturning about 30,000 statues, laws and rules........but I'm willing to make that sacrifice.
