If the private sector is challenged, technology is the answer to making schools safer. Another part of the consideration is public education itself. There shouldn't be State education that forces kids into building 6 to 8 hours five days a week. If education is left to the private sector and parents, solutions to threats of violence will arise. As a society we have transferred too much responsibility for children's safety to government. But aside from the point of safety, education will never be innovative and effective for everyone until it's taken away from government.
