In other parts of the US, the debate on gun control is going strong. Some people are questioning whether teachers should be armed with guns. While others believe the measure is necessary. Our reporter Dan Williams has the story from Chicago.

Afternoon on the south side of Chicago and school safety wardens prepare to give children a safe passage home. This is a neighborhood that knows all about gun violence. Helen Dumas is the principal at St. Sabina Academy. She believes two-thirds of her students have either lost a relative or a close friend to gun violence. Dumas has been watching the debate over gun control closely. She opposes the suggestion of allowing teachers the right to carry concealed weapons as a way to prevent school shootings.

HELEN DUMAS, PRINCIPAL ST. SABINA ACADEMY "I am absolutely against that. I just think it is ridiculous to ask teachers to get trained to shoot guns or invaders or whoever the case may be. Educators are trained to teach not to go to war."

This shooting range in Illinois offers free concealed gun carry classes for teachers. James Kruger is the president of the Illinois Association of Chiefs of Police. He believes schools should strengthen security. But he questions whether that should be with armed teachers.

JAMES KRUGER ILLINOIS ASSOCIATION OF CHIEFS OF POLICE "First of all, I think those folks have a lot of responsibility as it is right now. Police officers especially undergo a significant amount of training on a monthly basis on shoot-don't shoot situations. Are we going to expect that level of proficiency from a teacher I think is maybe a little misdirected."

DAN WILLIAMS CHICAGO "But not everyone agrees with that position. A school in southern Illinois is already looking at ways to arm teachers and other staff members. Although those at this school believe there are other solutions to the issue."

MARK WALSH ILLINOIS COUNCIL AGAINST HANDGUN VIOLENCE "What we have seen across this country is that more guns don't make us safer. It actually increases the risk of being shot and killed. We're in a school today talking about real solutions to the issue and that is more community involvement, more community engagement and knowing what is going on with friends, family and neighbors and that is how we reduce gun violence."

As the debate over concealed carry continues, many of the children here are preparing to add their voice to the national 'March for Our Lives'. For them, the answer is stricter gun controls. They hope their voices will be heard. Dan Williams, CGTN, Chicago.
