Parents go to your kids school and insist they have:
1. One Main Entrance for Each building with Metal Detectors.
2. Double Access Doors to be buzzed in by a secure person.
3. All classrooms kept locked from inside while kids in class, keyed access to inside classrooms.
4. Same for bathrooms, utility rooms..
5. All Exit doors self closing with alarms and keyed access from outside.
We Must Keep Our Children Safe.
