Not only is Arnold's law corrupt, the stupid reporter can't even get it right:
"...has backed previous landmark measures such as a 2004 ban on a particular type of machine gun."
"Machine guns?" I believe she meant .50 caliber rifles and revolvers.
It's worse than that. They baned the bullet [.50 BMG], not the gun. I am positive that .50 cal hand guns are still legal, so are .50 muzzle loaders and other variations of the .50 calibers. It's just he .50 BMG that they, in their infinite wisdom, banned.
