As a dad

One of the moment I really enjoy is waiting at the classroom door and pick up my kids from school by myself. As a dad, I really don’t want to read news like “Robb Elementary School shooting”. events like this happened so many time already, and many families and lives have been destroyed by it. Yet, people in power still won’t do nothing about it.
If the shooter had posted what he was going to do 15 minutes before the shooting, the piece of information must have been stored somewhere and monitored by the network somehow, can we have something build to monitor all major network and push notification nearby schools? I think we can.
