Could the School Shootings be link to conspiracies?

[Kallie]

OK, Im from Oklahoma and I am pro gun. I live in a town where almost every has an open carry, and children know gun safety at a young age. My husband will be teaching my son about gun safety soon ( He's 12) for hunting reason, recreation (Skeet Shooting), and protection. Its awful what happens at the schools such as Sandy Hook. I know its real and Those poor children really died but I hear (SOME of these shootings) that the government post things like its a training day or people make facebook pages days before the event actually happens. and I was just wondering does anyone know or even have any conclusive evidence that these shootings are set up?
