Same thing as what he said mainly. All these new laws were written during the clinton years BTW. They wanted to add shotguns to the list of weapons that needed to be registered like a machine gun. They got the Striker 12 added but the Mossberg wasn't since they look different. But they can hold the same amount of shotgun shells.
In Colorado they have close the "Gunshow loophole" thanks to those 2 pukes in columbine. They also held up CCW for a year too since it was progun and was still to hot of a topic. Those 2 could have benifited from some real parenting.
