Fear mongering

Started my web design course last night at the local college. It was so comforting to be told the procedures should a gunman enter the building and attempt to kill us all. We were told in all seriousness that we should turn off the lights, turn off our cell phones(???), close the door and move away from the look-through window. Basically - WE MUST GET OUT OF THE LINE OF FIRE. I couldn't believe it! I looked around the room incredulously (as thankfully some of the other people did) and wondered what the hell the world has come to.
