Make gun free zones illegal to allow the American people to protect themselves wherever they are as the 2nd allows

The 2nd amendment allows for Americans to bear arms. As such gun free zones prevent that. Criminals are not worried about breaking the gun free zone law. If we arm teachers and staff in schools, maybe only a few people would die before the gunman was taken down. Even a small handgun, not "Assault rifle," can kill 50+ people per minute. It may take a School Resource Officer over 2 minutes to reach the part of the building the shooting is taking place, which is easily 100+ people dead before they can be taken out. On the flip side, if every staff member was armed, the first office or classroom the shooter entered could be the last. Gun free zones make a place that a criminal will feel safe that they will have no return fire and can kill as many as possible before the police respond.
