A courageous school employee averted disaster on Tuesday by calmly talking down a man armed with an assault rifle who said that he has going to die and take as many others as possible with him. According to ABC News, Antoinette Tuff, the bookkeeper at the Ronald E. McNair Discovery Learning Center, convinced 20-year-old gunman Michael Brandon Hill to empty his pockets and backpack of ammunition and lie down on the floor so that police could take him into custody without incident.
