Over and over again, news outlets uncritically reported on the "common-sense" effort to implement more stringent background checks and get rid of automatic weapons, AR-15s and other "assault" weapons. Well, automatic weapons -- i.e., machine guns -- are already essentially banned for civilians. And the weapon used in Orlando wasn't an assault weapon or an AR-15. As for background checks, they already exist. Moreover, the FBI conducted two extensive investigations into the shooter -- a background check far more exhaustive than any proposed checks.
