Nothing magical about them, and like every other law in the history of the world, they aren't 100% effective, but they do reduce the number of guns for people that shouldn't have guns.
You didn't explain how that works...you just say it like it is the truth.......
Criminals steal their guns...they don't go through a background check for that...guns are not limited by that.
Criminals get relatives and other people with clean backgrounds to buy their guns for them....they bypass background checks that way...guns are not limited by that.
Mass shooters....pass background checks because they have committed no crime or they too steal their guns....guns are not limited by that.
Other than a mantra....repeated over and over again, or like a magical chant, "Background checks...ommmm....Background checks...ommmmmm...." Could one of you gun grabbers please explain how background checks keep criminals and mass shooters from getting guns?
