I don't have any new information on this, but wanted to comment on "smart guns" and the New Jersey legislature's rush to pass legislation mandating something before it even exists.
I view "smart guns" as a flank attack by anti gun types to gradually render existing guns illegal and replace them with "smart guns" that the government will be able to turn off at will. The antis know they can't win a direct assault on the Second Amendment and the banning of all guns outright. They don't have the political support for this.
So they have turned to a more subtle strategy of gradually eliminating existing "dumb" guns and replacing them with controllable guns. Although the smart gun will presumably only be usable by the registered owner, does anyone doubt that an electronic control that allows the gun to be turned on and off would eventually be under the control of the government? In the event of some emergency or revolution, the government would simply turn off all civilian owned guns, rendering them useless.
This is disarmament in slow motion.
