Moms form "Lives on the Line" group as gun violence fears become daily reality for parents

A group of moms decided to stage a protest in Kansas City on Thursday to coincide with the 24th anniversary of the Columbine High School shooting. They spent several weeks planning, not expecting that the recent shooting of teenager Ralph Yarl in Kansas City would thrust their community into the national debate on gun violence. 

The protest was the first major event organized by "Lives on the Line," a group Sara Ennis, Anna Simpson, Annie Noll and Eileen Knoblauch formed after the Nashville school shooting three weeks ago. They believe if they don't speak up, they're part of the problem.  

"We don't have enough White people who are willing to stand up and say: this is not right," Simpson said.
