As I understand it Christie wasn't so Gun Friendly as an US Prosecutor. About the only thing that he's done was let the poor guy out of jail who really didn't deserve to be there because the judge on the case wouldn't let the jury hear the letter of the law. Christie also removed that judge from the bench for a number of horrible legal rulings on all sorts of things.
About the best thing that came down the road has been a NJ court ruling that Gun ownership is a legal right in NJ (previously NJ courts have held that the 2nd amendment didn't apply in NJ and that gun ownership was a privilege.) Hopefully that and the court case to remove the Good and Substantial need clause (similar to MD) from our carry permit process will break the ice and start things going gun owner’s way in NJ.
Did you know you cannot lend a family member a gun unless you are actually present the entire time that family member has possession of it? Its things like this that drives us Jersey residents batty.
