Antoinette tuffAntoinette Tuff, a school clerk at an elementary school in Georgia, saw a gunman barge into the school and took action. She was not armed and had no prior training.

However, she had a back story, and she knew the gunman did, too. She remained calm and merely talked to the man carrying an AK-47 assault rifle.

She related to him, explaining that she had faced hardships as well; she was going through a divorce at the time, and her son has various disabilities. They talked for an hour, and she convinced him not to shoot anyone.
