The whole "we should let it play out in court" looks like Christie is just following constitutional separation of powers. In truth, it reflects the fact that a RINO like Christie is more than happy to have draconian, unconstitutional gun laws on the books, and only tosses a token sentence commutation here and there on the rare occasion that people are watching and it's politically expedient to make it seem like he cares about gun rights at all.
Don't worry, tubby, we're well aware of your actual views.
