Guns are the things most likely to kill young people in America

ON MAY 24TH an 18-year-old gunman, Salvador Ramos, walked into an elementary school in Uvalde, a town in south-west Texas, and shot dead at least 21 people, including 19 children. Mr Ramos was himself killed, reportedly by police. His motive remains unclear. It is the latest in a spate of mass shootings in America, and the toll is the biggest at a school since a gunman killed 26 people at Sandy Hook Elementary in Newtown, Connecticut, in 2012.
