SHELBYVILLE, Ind. -- At Southwestern High School in Indiana, the kids drill.
The classroom doors are bullet-resistant, cameras are everywhere and the sheriff's department -- only 10 miles away -- can track an intruder in real-time.
The school's cameras are connected and monitored at the sheriff's department.
Teachers all wear a panic button around their necks. Once push of the button sets off an alarm system to alert everyone of an intruder.
Teachers also have special boxes in their classrooms connected to the sheriff's department. A flip of a switch can call for help if the teacher's class is in danger. The switch can also be flipped to safe is the classroom isn't in danger.
The safety precautions don't stop there.
The school has a $400,000 "secret weapon" to stop intruders. Exploding smoke cannons, called "hot zones," are installed near the school doors and can be deployed in an instant. The smoke disorients and blinds the intruder.
