School is out for the summer, but DeSoto County residents received an education on school safety Wednesday. Hundreds of teachers, officers, and parents gathered at First Baptist Church in Southaven to learn how to make schools safer from Secret Service Agents. Agents say most school shootings can be prevented, and they base that information on interviews conducted with convicted shooters. Derek Verdyen, Memphis Secret Service said, "We've had the opportunity to interview them, find out what caused them do what they did. Did they tell anyone about it. So we will be sharing with them the interviews of most all the school shooting that most people have heard about." Agents say most attackers told others what they were planning to do beforehand. They also say school shootings are rarely impulsive, but are typically planned out in advance.
