ANDREW NAPOLITANO (FOX NEWS SENIOR JUDICIAL ANALYST): Our home state, New Jersey, our home state has the strictest background check in the union. It's not only a federal background check, it's a state. I have been through the state background check. They know everything about you. The killer in El Paso and the killer in Dayton would have passed the New Jersey background check. The background check is not the answer. The answer is an armed and trained citizenry.
