By ending gun free zones, such as schools, that will limit the damage and possibly end these mass shootings. When we arm citizens and teachers, we have a chance to fight back and stop the violence before it gets insane. Clearly, the gun free zones are not working, as evident by all the mass shootings. End these zones and arm citizens and teachers to end the violence. More gun control with not help. Criminals are criminals, and will get guns no matter what means, legal or illegal.
