Richard Arnold: US Correspondent says the Richneck School shooting has sent shockwaves through the community

Questions have been raised about whether parents should be held criminally responsible for gun crimes committed by children in the United States. A six-year-old boy has been taken into custody after shooting his teacher at Richneck Elementary School in Virginia. The teacher suffered life-threatening injuries, but is now in a stable condition. US correspondent Richard Arnold told Tim Dower that the crime has sent shockwaves through the community. He says there are questions about how a child of that age can access a gun, let alone take it to school to shoot a teacher. LISTEN ABOVESee omnystudio.com/listener for privacy information.
