High Tech Security Systems and officers involving schools... Is it necessary? It is necessary in my opinion because there are so many schools shootings taking place all over the world. these systems help keep tract of who ans what enters the school. I believe metal detectors on the doors would be a hood improvement because then you can really see when someones trying to cause a disruption. There's a big player in those things that most schools don't have though witch is money. Most places cant afford these things but if we can raise money for them? how many lives can we save by doing these kinda things in our schools?
