Southwestern Highschool

Ok guys. I see a lot of debates. Especially recently about teachers having guns in classrooms and how to adequately protect students during school shootings and Intruders. Well, at Southwestern Highschool in Indiana, they have it all figured out. Each teacher is equipped with a fob around their neck that has a panic button. If they click the button, the police are instantly notified. All of the doors also have the ability to lock and they are bullet proof. Essentially making everyone in the classrooms 100% safe. They also have a red line in every class that shows a zone where the students go to not be seen from the door window. In addition to all of that, there is a box in every class where the teachers can flip a switch and it calls the police and sends off an alarm throughout the entire school. There are also cameras everywhere. There were 6 just down the hallway and they are all connected to the police department and monitored by them, as well as school officials. Seems like enough right? Nope. They have smoke bombs that drop from the ceiling that they police or officials can drop where the intruder is located. Making it virtually impossible to see. With all of this put together, it's incredibly safe and no funds are involved. The downside? It's $400,000 per school. Personally, I think it's genius. What do you guys think? Would you say this is fool proof? Would you all pay extra in taxes to implement this in all schools?
