Craig Scott knows the pain that can be inflicted by anger and rage.
And he's also seen the power of kind words and acts of compassion.
Thursday, Scott made his second visit to Marion County, addressing middle and high school students, staff and the community.
Scott is a survivor of the Columbine school shooting that took place April 20, 1999. His sister, Rachel Joy Scott, was the first person killed by the shooters that day.
"She was a teenager that believed she could make a difference," Scott said.
