…….A complicating factor is how California law defines an “assault weapon.” Its definition does not deal with lethality, but rather a weapon’s “features” such as a detachable magazine or a pistol grip.
Thus two semi-automatic rifles that fire identical cartridges can be differentiated essentially by their appearance. One that looks scary because of its “features,” such as the AR-15, is supposedly banned while another that fires the same .223 cartridge, such as Ruger’s Mini-14, is perfectly legal.
One says “supposedly” because AR-15s and similar weapons are readily and legally available for sale in California after being rendered “featureless” by slight modifications to their appearance.
It means that state officials who defend California’s gun laws are in the awkward position of claiming that a weapon’s scary looks is sufficient cause to be prohibited.
“This is an average case about average guns used in average ways for average purposes,” Benitez said. “One is to be forgiven if one is persuaded by news media and others that the nation is awash with murderous AR-15 assault rifles. The facts, however, do not support this hyperbole, and facts matter.”
