CLANDESTINE SENSORS at schools and other public entrances would be uniquely set up to SPECIFICALLY AND IMMEDIATELY TRACK ALL TYPES OF CONCEALED FIREARMS at all building entrances. Firearms carried by hired security would already be cleared.
Federal laws will be enacted by Congress declaring that ALL REGISTERED (AND NON-REGISTERED) FIREARMS MUST BE RECALLED AND CHIPPED to be able to be tracked. All Americans would rally behind this. All law-abiding gun owners would be behind this. The NRA would be behind this to show its earnestness and solidarity to join in to help solve this serious problem.
