A high-school student opened fire today on his classmates in Conyers, Georgia... just one month after the deadly school massacre in Littleton, Colorado. President Clinton was in Littleton today, to offer consolation to the victims there. He called today's incident "deeply troubling" and asked all Americans to join in a national campaign to protect children from violence. Dr. Blanton Bessinger grew up near Conyers, Georgia and is currently the director of Child Advocacy for Children's hospital in Minneapolis . Bessinger who develops strategies for preventing juvenile violence, says Americans have been too tolerant of violent words and threats in school.
