All kidding aside, I think NJ is trying to ignore this:
From heller:
In sum, we hold that the District’s ban on handgun possession in the home violates the Second Amendment , as does its prohibition against rendering any lawful firearm in the home operable for the purpose of immediate self-defense. Assuming that Heller is not disqualified from the exercise of Second Amendment rights, the District must permit him to register his handgun and must issue him a license to carry it in the home.
Listened to Nappen's podcast, as usual he's right.
