10 years since Sandy Hook – what’s changed? Politics Weekly America special

On 14 December it will be 10 years since the Sandy Hook elementary school mass shooting, when a 20-year-old killed 20 children aged six and seven, as well as six adults. The Guardian’s Joan E Greve travelled to Newtown, Connecticut to speak with Nicole Hockley and Mark Barden of Sandy Hook Promise, the parents of Dylan and Daniel, who were killed that day. She meets teenagers from the Junior Newtown Action Alliance, who now go through terrifying lockdown drills as preparation for another shooting, who want to see more change in gun legislation. She also speaks with Senator Chris Murphy, who helped draft the first significant gun control policy in the US in 30 years this year. Together they discuss what more could and should be done to stop such tragedies
